Delivery!

MHCLG’s announcements this week have clarified three separate issues which go to whether the “tilted balance” in paragraph 11(d) of the NPPF applies in relation to applications for planning permission for housing development.

Where the tilted balance applies, Government policy is of course that planning permission should be granted unless:

(i) the application of policies in this Framework that protect areas or assets of particular importance [being specific categories of policies set out in footnote 6 to the NPPF] provides a clear reason for refusing the development proposed; or

(ii) any adverse impacts of doing so would significantly and demonstrably outweigh the benefits, when assessed against the policies in this Framework taken as a whole.”

Two situations where the tilted balance applies are:

⁃ “where the local planning authority cannot demonstrate a five year supply of deliverable housing sites” with an appropriate buffer percentage of 5%, 10% or 20% calculated by reference to paragraph 73 of the NPPF; and

⁃ “where the Housing Delivery Test indicates that the delivery of housing was substantially below [a defined percentage of] the housing requirement over the previous three years” the defined percentage being 25% in the case of Housing Delivery Test results published in November 2018, 45% in the case of results published in November 2019 and 75% in the case of results published in November 2020 and thereafter. (Additionally, the authority needs to publish an action plan where the delivery percentage is less than 95%, “to assess the causes of under-delivery and identify actions to increase delivery in future years“).

Paragraph 177 of the 2018 NPPF disapplies the presumption in favour of sustainable development (and therefore the possibility of the tilted balance applying) where the project requires appropriate assessment under the Conservation of Habitats Regulations, which has proved problematic following the Court of Justice of the European Union’s judgment in People Over Wind, which led to far more projects requiring appropriate assessment.

This week’s announcements have clarified three things:

1. How “deliverable” is defined for the purposes of that first situation.

2. The presumption in favour of sustainable development is no longer disapplied if there is a negative appropriate assessment.

3. What the November 2018 Housing Delivery Test results are for in relation to each English local planning authority (the results not having been, er, delivered on time by MHCLG).

After a long wait, and initial indications that this would all be done before Christmas, on 19 February MHCLG published:

Government response to technical consultation on updates to national planning policy and guidance

housing delivery test 2018 measurement

further revised NPPF

The revisions to the NPPF are limited but care will be needed when referring to decisions and court rulings to be clear as to the relevant policy basis: the 27 March 2012 NPPF, the 24 July 2018 NPPF or the 19 February 2019 NPPF.

What is deliverable?

Footnote 11 to the 2012 NPPF defined “deliverable” as follows:

To be considered deliverable, sites should be available now, offer a suitable location for development now, and be achievable with a realistic prospect that housing will be delivered on the site within five years and in particular that development of the site is viable. Sites with planning permission should be considered deliverable until permission expires, unless there is clear evidence that schemes will not be implemented within five years, for example they will not be viable, there is no longer a demand for the type of units or sites have long term phasing plans.”

The degree of probability required, given the words “realistic prospect“, was considered by the Court of Appeal in St Modwen Developments Ltd v Secretary of State (Court of Appeal, 20 October 2017), where Lindblom LJ said this:

35…Deliverability is not the same thing as delivery. The fact that a particular site is capable of being delivered within five years does not mean that it necessarily will be. For various financial and commercial reasons, the landowner or housebuilder may choose to hold the site back. Local planning authorities do not control the housing market. NPPF policy recognises that…


37… Had the Government’s intention been to frame the policy for the five-year supply of housing land in terms of a test more demanding than deliverability, this would have been done…


38 The first part of the definition in footnote 11—amplified in paras 3–029, 3–031 and 3–033 of the PPG—contains four elements: first, that the sites in question should be ” available now”; second, that they should “offer a suitable location for development now”; third, that they should be ” achievable with a realistic prospect that housing will be delivered on the site within five years”; and fourth, that “development of the site is viable ” (my emphasis). Each of these considerations goes to a site’s capability of being delivered within five years: not to the certainty, or—as Mr Young submitted—the probability that it actually will be. The second part of the definition refers to “[sites] with planning permission”. This clearly implies that, to be considered deliverable and included within the five-year supply, a site does not necessarily have to have planning permission already granted for housing development on it. The use of the words “realistic prospect” in the footnote 11 definition mirrors the use of the same words in the second bullet point in paragraph 47 in connection with the requirement for a 20% buffer to be added where there has been “a record of persistent under delivery of housing”. Sites may be included in the five-year supply if the likelihood of housing being delivered on them within the five-year period is no greater than a “realistic prospect”—the third element of the definition in footnote 11 (my emphasis). This does not mean that for a site properly to be regarded as “deliverable” it must necessarily be certain or probable that housing will in fact be delivered upon it, or delivered to the fullest extent possible, within five years.”

The wording in glossary to the 2018 NPPF was made more specific:

“”Deliverable: To be considered deliverable, sites for housing should be available now, offer a suitable location for development now, and be achievable with a realistic prospect that housing will be delivered on the site within five years. Sites that are not major development, and sites with detailed planning permission, should be considered deliverable until permission expires, unless there is clear evidence that homes will not be delivered within five years (e.g. they are no longer viable, there is no longer a demand for the type of units or sites have long term phasing plans). Sites with outline planning permission, permission in principle, allocated in the development plan or identified on a brownfield register should only be considered deliverable where there is clear evidence that housing completions will begin on site within five years.”

Due to concerns as to potential ambiguity (which I didn’t really see) as to the treatment of non-major development (ie developments of less than ten homes, with a site area of less than 0.5 hectares), the wording has now been changed in the 2019 NPPF to read as follows

“Deliverable: To be considered deliverable, sites for housing should be available now, offer a suitable location for development now, and be achievable with a realistic prospect that housing will be delivered on the site within five years. In particular:

a)  sites which do not involve major development and have planning permission, and all sites with detailed planning permission, should be considered deliverable until permission expires, unless there is clear evidence that homes will not be delivered within five years (for example because they are no longer viable, there is no longer a demand for the type of units or sites have long term phasing plans).

b)  where a site has outline planning permission for major development, has been allocated in a development plan, has a grant of permission in principle, or is identified on a brownfield register, it should only be considered deliverable where there is clear evidence that housing completions will begin on site within five years

But there will remain room for argument: “realistic prospect” inevitably requires judgement and the local planning authority’s assessment as to the position of individual sites will always be potentially controversial given its interest (and/or that of objectors to development) in demonstrating an adequate supply so as to avoid the tilted balance. We will no doubt still see cases such as East Cheshire Council v Secretary of State (Deputy Judge Justine Thornton QC, 1 November 2018), East Bergholt Parish Council v Babergh District Council (Sir Ross Cranston, 7 December 2018) and (no transcript available but the link is to a useful Cornerstone summary) R (Chilton Parish Council) v Babergh District Council (Deputy Judge Robin Purchas QC, 2 February 2019.

There has also previously been much uncertainty as to the circumstances in which the new standard method for assessing local housing need should be used as the basis for assessing whether a five year supply of specific deliverable sites exists in the case of a plan with strategic policies which are more than five years old (unless those strategic policies had been reviewed and found not not to require updating). Footnote 37 in the 2019 NPPF makes clear that the standard method should indeed be used (which reflects the 5 February 2019 decision of the Secretary of State in relation to the Edenthorpe Doncaster called in application, blogged about by Lichfields on 21 February 2019).

Appropriate assessment

Hooray, paragraph 177 now reads:

The presumption in favour of sustainable development does not apply where the plan or project is likely to have a significant effect on a habitats site (either alone or in combination with other plans or projects), unless an appropriate assessment has concluded that the plan or project will not adversely affect the integrity of the habitats site.

The Housing Delivery Test

Well, the results are finally in. The housing delivery test 2018 measurement. According to analysis by Savills:

⁃ no authority is subject this time round to the tilted balance by virtue of delivering less than 25% of its housing requirement over the last three years

⁃ 86 out of 326 authorities are subject to the requirement of a 20% buffer on their five year housing land supply figure as a result of having delivered less than 85% of their housing requirement over the last three years

⁃ 107 out of 326 authorities have to prepare an action plan as a result of having delivered less than 95% of their housing requirement over the last three years.

A future blog post will deal with the “need” side of the equation…
