When I saw a limelon for the first time yesterday (some recently marketed lime/melon hybrid since you ask, and tangy and refreshing it is indeed), I naturally thought of the proposed combined infrastructure levy: what on earth is it?
Planning For The Future is of course work in progress and it may be churlish for us to expect it to have all the answers. After all, it is up to us to provide cogent responses to the current consultation process.
But the sections in the document on infrastructure contributions are very light indeed, given the central role that section 106 and the community infrastructure levy play in the current system and the obvious complexity of arriving at a system for a combined infrastructure levy that on the one hand does not choke off various forms of development in some areas by making it unviable and that on the other hand both (1) raises sufficient monies to secure the delivery of necessary social (e.g. affordable housing) and physical infrastructure and also (2) ensures for the benefit of both communities and developers that the infrastructure will actually be provided in the right place, at the right time.
The lightness is in contrast to the detailed analysis of the existing position in relation to contributions by way of CIL and section 106 planning obligations that is the subject of a detailed study (143 pages) by respected academics (all those listed on the front page of the document), The Incidence, Value and Delivery of Planning Obligations and Community Infrastructure Levy in England in 2018-19, published alongside the white paper.
The objectives of the study were to
•Update the evidence on the current value and incidence of planning obligations
• Investigate the relationship between CIL and S106
• Understand negotiation processes and delays to the planning process
• Explore the monitoring and transparency of developer contributions
• Understand the early effects and expectations for the changes to developer contributions brought in by the revisions to the NPPF
Chapter 3 (The value of Planning Obligations and the Community Infrastructure Levy) sets out some interesting findings:
“• The estimated value of planning obligations agreed and CIL levied in 2018/19 was £7.0 billion. This valuation is premised upon the assumptions identified in the appendix, corresponding to survey validity, respondent representation and the distribution of values.
• When adjusted to reflect inflation the total value of developer contributions in real terms is £500 million higher than in 2016/17, £300 million higher than in 2007/08.
• 67% of the value of agreed developer contributions was for the provision of affordable housing, at £4.7 billion; this is the same proportion as in 2016/17 and is the joint-highest to date.
• 44,000 affordable housing dwellings were agreed in planning obligations in 2018/19. This is a reduction since 2016/17, but the value of this housing has increased over the same period due to an increase in house prices in many areas with higher developer contributions.
• The value of CIL levied by LPAs was £830 million in 2018/19, with a further £200 million levied by the Mayor of London.
• The geographic distribution of planning obligations and CIL is weighted heavily towards the south of England. The South East, South West and London regions account for 61% of the total value. However, the value of developer contributions exacted in London has fallen since 2016/17 – down from 38% to 28% of the total aggregate value.”
There is nothing in the white paper that explicitly draws from the findings of that report in order to arrive at the wholly new mechanism that is proposed.
Some people seem to have picked up the message that the white paper means the end of the community infrastructure levy – a cause for celebration in some parts. But the white paper’s proposal for a combined infrastructure levy to my mind is CIL writ large, potentially just as complex, with a whole new set of rate setting, liability, payment and spending mechanisms and with the express objective of raising more monies than the current system. It warrants its own focus at this point, away from the noise of the other proposals in the white paper.
How to begin to unpick what is proposed in relation to CIL and section 106 planning obligations (and what the proposals in relation to section 106 mean for the delivery of affordable housing in particular)? I wrote down for myself five basic questions:
1. How will planning obligations work under the new system?
2. What will happen to CIL?
3. How will the new Combined Infrastructure Levy be set?
4. What requirements will there be on local authorities as to how they apply combined infrastructure levy receipts?
5. Under the new system, how can local planning authorities set requirements for affordable housing and seek to ensure that they are delivered?
In order to try to answer them (in a way which would have to work in relation to all of the proposed consenting routes: DCO, outline planning permission in plan, PiP (if different from outline permission in plan, not sure!), traditional planning permission, PD), then I cut and pasted the relevant passages from the white paper in their entirety (only leaving out the detail of some of the “alternative options” floated and leaving out the questions raised in the consultation). It is easy to read summaries and think “well there must be more detail in the document itself”. It is worth reading these passages to see the totality of the proposals.
After these passages I then see how far we can get in answering my questions.
“The process for negotiating developer contributions to affordable housing and infrastructure is complex, protracted and unclear: as a result, the outcomes can be uncertain, which further diminishes trust in the system and reduces the ability of local planning authorities to plan for and deliver necessary infrastructure. Over 80 per cent of planning authorities agree that planning obligations cause delay. It also further increases planning risk for developers and landowners, thus discouraging development and new entrants.”
“1.19. Fourth, we will improve infrastructure delivery in all parts of the country and ensure developers play their part, through reform of developer contributions. We propose:
• The Community Infrastructure Levy and the current system of planning obligations will be reformed as a nationally-set value-based flat rate charge (‘the Infrastructure Levy’). A single rate or varied rates could be set. We will aim for the new Levy to raise more revenue than under the current system of developer contributions, and deliver at least as much – if not more – on-site affordable housing as at present. This reform will enable us to sweep away months of negotiation of Section 106 agreements and the need to consider site viability. We will deliver more of the infrastructure existing and new communities require by capturing a greater share of the ulpift [sic] in land value that comes with development.
• We will be more ambitious for affordable housing provided through planning gain, and we will ensure that the new Infrastructure Levy allows local planning authorities to secure more on-site housing provision.
• We will give local authorities greater powers to determine how developer contributions are used, including by expanding the scope of the Levy to cover affordable housing provision to allow local planning authorities to drive up the provision of affordable homes. We will ensure that affordable housing provision supported through developer contributions is kept at least at current levels, and that it is still delivered on-site to ensure that new development continues to support mixed communities. Local authorities will have the flexibility to use this funding to support both existing communities as well as new communities.
• We will also look to extend the scope of the consolidated Infrastructure Levy and remove exemptions from it to capture changes of use through permitted development rights, so that additional homes delivered through this route bring with them support for new infrastructure.
“4.5. Securing necessary infrastructure and affordable housing alongside new development is central to our vision for the planning system. We want to bring forward reforms to make sure that developer contributions are:
• responsive to local needs, to ensure a fairer contribution from developers for local communities so that the right infrastructure and affordable housing is delivered;
• transparent, so it is clear to existing and new residents what new infrastructure will accompany development;
• consistent and simplified, to remove unnecessary delay and support competition in the housebuilding industry;
• buoyant, so that when prices go up the benefits are shared fairly between developers and the local community, and when prices go down there is no need to re-negotiate agreements.
4.6. The Government could also seek to use developer contributions to capture a greater proportion of the land value uplift that occurs through the grant of planning permission, and use this to enhance infrastructure delivery. There are a range of estimates for the amount of land value uplift currently captured, from 25 to 50 per cent. The value captured will depend on a range of factors including the development value, the existing use value of the land, and the relevant tax structure – for instance, whether capital gains tax applies to the land sale. Increasing value capture could be an important source of infrastructure funding but would need to be balanced against risks to development viability.”
“4.7. We propose that the existing parallel regimes for securing developer contributions are replaced with a new, consolidated ‘Infrastructure Levy’.
Proposal 19: The Community Infrastructure Levy should be reformed to be charged as a fixed proportion of the development value above a threshold, with a mandatory nationally-set rate or rates and the current system of planning obligations abolished.”
“4.8. We believe that the current system of planning obligations under Section 106 should be consolidated under a reformed, extended ‘Infrastructure Levy’.
4.9. This would be based upon a flat-rate, valued-based charge, set nationally, at either a single rate, or at area-specific rates. This would address issues in the current system as it would:
be charged on the final value of a development (or to an assessment of the sales value where the development is not sold, e.g. for homes built for the rental market), based on the applicable rate at the point planning permission is granted;
• be levied at point of occupation, with prevention of occupation being a potential sanction for non-payment;
• include a value-based minimum threshold below which the levy is not charged, to prevent low viability development becoming unviable, reflecting average build costs per square metre, with a small, fixed allowance for land costs. Where the value of development is below the threshold, no Levy would be charged. Where the value of development is above the threshold, the Levy would only be charged on the proportion of the value that exceeded the threshold ; and
• provide greater certainty for communities and developers about what the level of developer contributions are expected alongside new development.
4.10. The single rate, or area-specific rates, would be set nationally. It would aim to increase revenue levels nationally when compared to the current system. Revenues would continue to be collected and spent locally.
4.11. As a value-based charge across all use classes, we believe it would be both more effective at capturing increases in value and would be more sensitive to economic downturns. It would reduce risk for developers, and would reduce cashflow difficulties, particularly for SME developers.
4.12. In areas where land value uplift is insufficient to support significant levels of land value capture, some or all of the value generated by the development would be below the threshold, and so not subject to the levy. In higher value areas, a much greater proportion of the development value would be above the exempt amount, and subject to the levy.
4.13. To better support the timely delivery of infrastructure, we would also allow local authorities to borrow against Infrastructure Levy revenues so that they could forward fund infrastructure. Enabling borrowing combined with a shift to levying developer contributions on completion, would incentivise local authorities to deliver enabling infrastructure, in turn helping to ensure development can be completed faster. As with all volatile borrowing streams, local authorities should assure themselves that this borrowing is affordable and suitable.
4.14. Under this approach the London Mayoral Community Infrastructure Levy, and similar strategic Community Infrastructure Levies in combined authorities, could be retained as part of the Infrastructure Levy to support the funding of strategic infrastructure.
4.15. In bringing forward the reformed Infrastructure Levy, we will need to consider its scope. We will also consider the impact of this change on areas with lower land values.”
Alternative options proposed: “The Infrastructure Levy could remain optional and would be set by individual local authorities”. “Alternatively, the national rate approach could be taken, but with the aim of capturing more land value than currently, to better support the delivery of infrastructure”
“Proposal 21: The reformed Infrastructure Levy should deliver affordable housing provision
4.20. Developer contributions currently deliver around half of all affordable housing, most of which is delivered on-site. It is important that the reformed approach will continue to deliver on-site affordable housing at least at present levels.
4.21. Affordable housing provision is currently secured by local authorities via Section 106, but the Community Infrastructure Levy cannot be spent on it. With Section 106 planning obligations removed, we propose that under the Infrastructure Levy, authorities would be able to use funds raised through the levy to secure affordable housing.
4.22. This could be secured through in-kind delivery on-site, which could be made mandatory where an authority has a requirement, capability and wishes to do so. Local authorities would have a means to specify the forms and tenures of the onsite provision, working with a nominated affordable housing provider. Under this approach, a provider of affordable housing could purchase the dwelling at a discount from market rate, as now. However, rather than the discount being secured through Section 106 planning obligations, it would instead be considered as in-kind delivery of the Infrastructure Levy. In effect, the difference between the price at which the unit was sold to the provider and the market price would be offset from the final cash liability to the Levy. This would create an incentive for the developer to build on-site affordable housing where appropriate. [Footnote: As above, a Section 106 planning obligation could still be used to secure a covenant on the land, where necessary. However, the value would be captured through the Infrastructure Levy, rather than Section 106. ] First Homes, which are sold by the developer direct to the customer at a discount to market price, would offset the discount against the cash liability.
4.23. Under this approach we recognise that some risk is transferring to the local planning authority, and that we would need to mitigate that risk in order to maintain existing levels of on-site affordable housing delivery. We believe that this risk can be fully addressed through policy design. In particular, in the event of a market fall, we could allow local planning authorities to ‘flip’ a proportion of units back to market units which the developer can sell, if Levy liabilities are insufficient to cover the value secured through in-kind contributions. Alternatively, we could require that if the value secured through in-kind units is greater than the final levy liability, then the developer has no right to reclaim overpayments. Government could provide standardised agreements, to codify how risk sharing would work in this way.
4.24. We would also need to ensure the developer was incentivised to deliver high build and design quality for their in-kind affordable homes. Currently, if Section 106 homes are not of sufficient quality, developers may be unable to sell it to a provider, or have to reduce the price. To ensure developers are not rewarded for low standard homes under the Levy, local authorities could have an option to revert back to cash contributions if no provider was willing to buy the homes due to their poor quality. It is important that any approach taken maintains the quality of affordable housing provision as well as overarching volumes, and incentivises early engagement between providers of affordable housing and developers. Local authorities could also accept Infrastructure Levy payments in the form of land within or adjacent to a site. Through borrowing against further Infrastructure Levy receipts, other sources of funding, or in partnership with affordable housing providers, they could then build affordable homes, enabling delivery at pace.
4.25. Alternative option: We could seek to introduce further requirements around the delivery of affordable housing. To do this we would create a ‘first refusal’ right for local authorities or any affordable housing provider acting on their behalf to buy up to a set proportion of on-site units (on a square metre basis) at a discounted price, broadly equivalent to build costs. The proportion would be set nationally, and the developer would have discretion over which units were sold in this way. A threshold would be set for smaller sites, below which on-site delivery was not required, and cash payment could be made in lieu. Where on-site units were purchased, these could be used for affordable housing, or sold on (or back to the developer) to raise money to purchase affordable housing elsewhere. The local authority could use Infrastructure Levy funds, or other funds, in order to purchase units.”
“Proposal 22: More freedom could be given to local authorities over how they spend the Infrastructure Levy
4.26. It is important that there is a strong link between where development occurs and where funding is spent. Currently, the Neighbourhood Share of the Community Infrastructure Levy ensures that up to 25 per cent of the levy is spent on priorities in the area that development occurred, with funding transferred to parish councils in parished areas. There are fewer restrictions on how this funding is spent, and we believe it provides an important incentive to local communities to allow development in their area. We therefore propose that under this approach the Neighbourhood Share would be kept, and we would be interested in ways to enhance community engagement around how these funds are used, with scope for digital innovation to promote engagement.
4.27. There is scope for even more flexibility around spending. We could also increase local authority flexibility, allowing them to spend receipts on their policy priorities, once core infrastructure obligations have been met. In addition to the provision of local infrastructure, including parks, open spaces, street trees and delivery or enhancement of community facilities, this could include improving services or reducing council tax. The balance of affordable housing and infrastructure may vary depending on a local authority’s circumstances, but under this approach it may be necessary to consider ring-fencing a certain amount of Levy funding for affordable housing to ensure that affordable housing continues to be delivered on-site at current levels (or higher). There would also be opportunities to enhance digital engagement with communities as part of decision making around spending priorities. Alternatively, the permitted uses of the Levy could remain focused on infrastructure and affordable housing, as they are broadly are at present. Local authorities would continue to identify the right balance between these to meet local needs, as they do at present.”
“ 5.19. If a new approach to development contributions is implemented, a small proportion of the income should be earmarked to local planning authorities to cover their overall planning costs, including the preparation and review of Local Plans and design codes and enforcement activities.”
Back to my questions:
1. How will planning obligations work under the new system?
It is said in the paper that the “current system of planning obligations under Section 106 should be consolidated under a reformed, extended ‘Infrastructure Levy’.” There will no longer be “months of negotiation of Section 106 agreements”. “Section 106 planning obligations [will be] removed”.
The proposals seem to assume that section 106 is simply a mechanism for securing provision of affordable housing and other “developer contributions”. Whilst that is its main role at present, it is a mechanism for a wide range of commitments – see this table from the accompanying study:

The joy of section 106 is its flexibility to circumstances and policy, enabling the applicant commit to commit, in a way that binds successors in title, to all necessary mitigation measures that cannot be secured by way of planning condition and which are necessary to overcome what would otherwise be reasons not to allow the proposed development to proceed. On more complex developments it is the only tried and tested way in which appropriate mechanisms can be arrived at to make sure that, for instance, necessary infrastructure comes forward at the right time and by way of a sensible process, bespoke to the circumstances of the development, agreed between the parties. There is no proposal in the paper (although it has previously been floated by some) that the role of planning conditions could be expanded.
Where financial contributions are paid to a local planning authority under a section 106 agreement they can only be used for the specified purposes, whereas the proposals in relation to the consolidated infrastructure levy appear to be more loose: “We could also increase local authority flexibility, allowing them to spend receipts on their policy priorities, once core infrastructure obligations have been met.”What is meant by “core infrastructure obligations”? The core infrastructure obligations necessary to make a particular development acceptable? If so, then a document will need to be drawn up which surely will be as complex as a section 106 agreement – when will the school come forward, using the developer’s infrastructure levy contribution, how, where and when? Local employment and training measures, provision and maintenance of open space and play areas, carbon reduction commitments, commitments to specified transport improvements and the formulation and implementation of transport plans – are all these to be swept away? If so, the document needs to explain either why this is acceptable and desirable or how these matters will otherwise be addressed.
Additional confusion arises when these bold statements as to the removal of section 106 obligations are then contrasted with the footnote to paragraph 4.22: “As above, a Section 106 planning obligation could still be used to secure a covenant on the land, where necessary. However, the value would be captured through the Infrastructure Levy, rather than Section 106”. What does that mean? What would the “covenant on the land” and if the only point is to make sure that the infrastructure levy binds successors in title, why not leave that for the legislation itself?
Is anyone out there clearer at this stage ?
2. What will happen to CIL?
The community infrastructure levy will be replaced by the consolidated infrastructure levy, which will work in various significantly different ways to the current system. For instance:
• It will be a “nationally-set value-based flat rate charge”. I try to unpick this in my answer to question 3 below.
• It will be “levied at point of occupation”.
• “Revenues would continue to be collected and spent locally.”
• “we would also allow local authorities to borrow against Infrastructure Levy revenues so that they could forward fund infrastructure. Enabling borrowing combined with a shift to levying developer contributions on completion, would incentivise local authorities to deliver enabling infrastructure, in turn helping to ensure development can be completed faster.” [If a developer needs specific infrastructure to be delivered in order to enable development to proceed, how will this be documented? What if, as is usually the case, the developer would prefer to deliver the infrastructure, e.g. build the school?]
• The “London Mayoral Community Infrastructure Levy, and similar strategic Community Infrastructure Levies in combined authorities, could be retained as part of the Infrastructure Levy to support the funding of strategic infrastructure” [Is this retained as in retained under the current CIL system so that in London CIL would continue to operate alongside the new levy, or is this retained as in “rolled into”?]
• “We will also look to extend the scope of the consolidated Infrastructure Levy and remove exemptions from it to capture changes of use through permitted development rights” [This is odd – development pursuant to PD rights is not exempt from CIL at the moment. Is this flagging more widely that exemptions will be removed? That would have been a sensible, simplifying, approach were CIL levels to be reduced, but here we are faced with an increased Infrastructure Levy…]
3. How will the new Combined Infrastructure Levy be set?
• It will be a “nationally-set value-based flat rate charge, set nationally, at either a single rate, or at area-specific rates”. [Clearly this can’t in any circumstances mean a nationally-set flat rate charge of x per square metres but must mean a nationally-set proportion of (I assume) gross development value.]
• There will be “a value-based minimum threshold below which the levy is not charged, to prevent low viability development becoming unviable, reflecting average build costs per square metre, with a small, fixed allowance for land costs. Where the value of development is below the threshold, no Levy would be charged. Where the value of development is above the threshold, the Levy would only be charged on the proportion of the value that exceeded the threshold”. [When would the developer have certainty that the threshold was not exceeded, or indeed as to what the value (and therefore charge) is considered to be, through what procedure and with what rights to appeal against the valuation? Is the valuation a notional one, applying a formula, or an actual valuation?]
• “buoyant, so that when prices go up the benefits are shared fairly between developers and the local community, and when prices go down there is no need to re-negotiate agreements.” [the timing of the valuation date will be critical, as will how to deal with phased and revised schemes and so on].
• “It would aim to increase revenue levels nationally when compared to the current system” [so more than £7bn, on the basis of the findings in that study – in a way which will need not to disincentivise owners and developers from carrying out development].
That’s all I can glean from the document. It seems to me that local planning authorities will lose much flexibility, for instance in the setting of differential rates for different types of floorspace (the document does focus to a significant extent on residential development – what rate would be set for, say, offices, logistics or retail, particularly given the weaker relationship between non-residential uses and the delivery of affordable housing, and what about not for profit development – will we need to reintroduce a number of the current CIL exemptions?
4. What requirements will there be on local authorities as to how they apply combined infrastructure levy receipts?
• “With Section 106 planning obligations removed, we propose that under the Infrastructure Levy, authorities would be able to use funds raised through the levy to secure affordable housing”. I try to unpick this in my answer to question 5 below.
• “We could also increase local authority flexibility, allowing them to spend receipts on their policy priorities, once core infrastructure obligations have been met. In addition to the provision of local infrastructure, including parks, open spaces, street trees and delivery or enhancement of community facilities, this could include improving services or reducing council tax.” [So, infrastructure levy surplus receipts (after delivery of “core infrastructure”) become unhypothecated tax receipts – the less the authority spends on infrastructure, the lower it can keep its council tax, hmm…]?
• “If a new approach to development contributions is implemented, a small proportion of the income should be earmarked to local planning authorities to cover their overall planning costs, including the preparation and review of Local Plans and design codes and enforcement activities.”
5. Under the new system, how can local planning authorities set requirements for affordable housing and seek to ensure that they are delivered?
• “We will be more ambitious for affordable housing provided through planning gain, and we will ensure that the new Infrastructure Levy allows local planning authorities to secure more on-site housing provision”.
• “This could be secured through in-kind delivery on-site, which could be made mandatory where an authority has a requirement, capability and wishes to do so. Local authorities would have a means to specify the forms and tenures of the onsite provision, working with a nominated affordable housing provider. Under this approach, a provider of affordable housing could purchase the dwelling at a discount from market rate, as now. However, rather than the discount being secured through Section 106 planning obligations, it would instead be considered as in-kind delivery of the Infrastructure Levy. In effect, the difference between the price at which the unit was sold to the provider and the market price would be offset from the final cash liability to the Levy. This would create an incentive for the developer to build on-site affordable housing where appropriate. First Homes, which are sold by the developer direct to the customer at a discount to market price, would offset the discount against the cash liability.” [So presumably the developer could net-off the costs of on-site delivery from its infrastructure levy liability. How is this to be documented? Who adjudicates on the obvious valuation issues arising?]
• “Under this approach we recognise that some risk is transferring to the local planning authority, and that we would need to mitigate that risk in order to maintain existing levels of on-site affordable housing delivery. We believe that this risk can be fully addressed through policy design. In particular, in the event of a market fall, we could allow local planning authorities to ‘flip’ a proportion of units back to market units which the developer can sell, if Levy liabilities are insufficient to cover the value secured through in-kind contributions. Alternatively, we could require that if the value secured through in-kind units is greater than the final levy liability, then the developer has no right to reclaim overpayments. Government could provide standardised agreements, to codify how risk sharing would work in this way” [How to safeguard against misuse?]
• “To ensure developers are not rewarded for low standard homes under the Levy, local authorities could have an option to revert back to cash contributions if no provider was willing to buy the homes due to their poor quality.”
• “Local authorities could also accept Infrastructure Levy payments in the form of land within or adjacent to a site.” [Back to ensuring a robust valuation process].
Again, maybe it’s just me but I’m left scratching my head. This is a wholly different approach to extracting contributions for affordable housing and for ensuring that they are delivered. Basic questions:
• How will the requirements (quantum, tenure mix, size] be set at policy stage and determined at application stage (in advance of valuations) such that there can be confidence that development will not be stalled through lack of viability?
• Are we moving to a system where all affordable housing is delivered by a local authority nominated housing provider, with less ability for the developer to seek to improve viability?
• How can there be any confidence that this mechanism will result in more on-site affordable housing than at present?
I also recommend George Venning’s LinkedIn piece on the issues arising: Planning Reforms Contain a Poison Pill.
Again, thoughts welcome – it’s not that the proposals can’t be made to work, it’s just that much more input is required and, in my view, a cautious approach needs to be taken so as to guard against the inevitable unintended consequences.
The deadline for consultation responses is 29 October. We are likely to be collating a Town response, if only on specific issues such as this. If you would be interested in feeding in your thoughts, then please let me know, although, health warning, we are not in the business of designing fruit by committee!
