“It’s the economy, stupid.”
More E words: the English planning and property community was immediately, depending who you spoke to, exercised/excited by the changes to the Use Classes Order and General Permitted Development Order this week. Surprisingly so perhaps, given how heavily the changes had previously been trailed (although, it must be said, in terms of the Use Classes Order changes, not consulted upon). Inevitably and by contrast, the wider public appears to be oblivious as to what lies ahead, despite the potentially far-reaching implications of the creation of the new “commercial, business and service“ class E within the Use Classes Order in particular.
There are many good summaries already of the changes. My Town colleagues Nikita Sellers, George Morton Jack and Meeta Kaur have prepared a detailed summary.
I am not going to consider the rights and wrongs of the changes in any detail. I have referred previously to my disappointment that the Government has not required for example its nationally described minimum space standards to be applied in relation to the creation of new dwellings by way of permitted development rights (despite having published, with curious timing, a report Research into the quality standard of homes delivered through change of use permitted development rights, on the same day as publishing legislation which does not take into account the recommendations of that work, with no explanation for the discrepancy). The Use Classes Order changes do provide some overdue flexibility given the structural changes underway in our town centres in the light of changed shopping patterns (not just Covid-related but of course now accentuated), but they are extremely wide ranging and I query whether the various permutations of potential consequences have been adequately considered. But that is all for another day.
Instead, I wanted to pull us back to some planning law fundamentals – in what circumstances may owners find that they cannot rely on the expanded use rights after all?
First, in order to move within a use class, the initial use first has to have been instituted, so if for instance you have an as yet unimplemented planning permission for a shop, or if the development has been built but not yet been occupied, the development will first need to have been used as a shop before there can be a change to another use within the new class E (e.g. offices).
Secondly, there must not be a condition on the planning permission authorising the current use that has the effect of preventing use changes that would otherwise have been enabled by way of the Use Classes Order and/or General Permitted Development Order. This is familiar but not straightforward territory. There is much case law as to whether particular phrases in conditions actually achieved what the local planning authority intended and indeed whether the benefit of the condition was lost through the grant of subsequent permissions which did not expressly impose it.
The general answer is that it depends on a careful analysis of the existing planning permission (and of course any provisions within any section 106 agreement).
The Supreme Court considered a situation like this in London Borough of Lambeth v Secretary of State (Supreme Court, 3 July 2019), which I summarised in my 4 July 2019 blog post What Really Is The Meaning Of Lambeth?
The original permission read:
“The retail unit hereby permitted shall be used for the retailing of goods for DIY home and garden improvements and car maintenance, building materials and builders’ merchants goods and for no other purpose (including any other purpose in Class I of the Schedule to the Town and Country Planning (Use Classes) Order 1972 or in any provision equivalent to that Class in any statutory instrument revoking and re-enacting that Order).”
It was then amended to read:
“The retail use hereby permitted shall be used for the retailing of DIY home and garden improvements and car maintenance, building materials and builders merchants goods, carpets and floor coverings, furniture, furnishings, electrical goods, automobile products, camping equipment, cycles, pet and pet products, office supplies and for no other purpose (including the retail sale of food and drink or any other purpose in Class A1 of the Schedule to the Town and Country Planning (Use Classes) Order 1987 (as amended) or in any provision equivalent to that Class in any statutory instrument revoking and re-enacting that Order).”
The council then approved by way of section 73 a further change so that it was to read:
“The retail unit hereby permitted shall be used for the sale and display of non-food goods only and, notwithstanding the provisions of the Town and Country Planning (General Permitted Development) Order 1995 (or any Order revoking and re-enacting that Order with or without modification), for no other goods.”
However, the council neglected to include that wording in a condition. It was simply part of the description of the development.
The Supreme Court held that the permission was to be interpreted as constraining the use of the retail unit so that it was for the sale of non-food goods only. But for our purposes, this is an example that the courts (1) routinely treat conditions as able validly to restrict the operation of the Use Classes Order and/or General Permitted Development Order and (2) are perhaps currently more benevolent towards the local planning authority’s position than has previously been the case where there has been procedural imprecision, as long as what was intended was clear.
My 14 October 2017 blog post Flawed Drafting: Interpreting Planning Permissions referred to another recent example, Dunnett Investments Limited v Secretary of State (Court of Appeal, 29 March 2017) which concerned this condition:
“This use of this building shall be for purposes falling within Class B1 (Business) as defined in the Town and Country Planning (Use Classes) Order 1987, and for no other purpose whatsoever, without express planning consent from the Local Planning Authority first being obtained“.
The court held that “express planning consent” did not include prior approval pursuant to the “office to residential” permitted development right. The restriction applied.
So care is needed! Where there are restrictive conditions which would restrict the flexibility that the new class E would otherwise give, of course consideration can be given to applying to remove those conditions by way of section 73 application.
Thirdly, when applications for planning permission are now to be determined, careful consideration will need to be given to the proposed description of development and no doubt there will be issues arising as to whether decision makers are justified in imposing conditions which restrict the operation of the new Use Classes Order and General Permitted Development Order flexibilities. It will be the B1(a), (b) and (c) arguments all over again, but writ large.
I hope that we will have updated Planning Practice Guidance. In the meantime, the current Planning Practice Guidance has passages such as these:
“It is important to ensure that conditions are tailored to tackle specific problems, rather than standardised or used to impose broad unnecessary controls.”
1. necessary;
2. relevant to planning;
3. relevant to the development to be permitted;
4. enforceable;
5. precise; and
6. reasonable in all other respects.”
“Is it appropriate to use conditions to restrict the future use of permitted development rights or changes of use?
Conditions restricting the future use of permitted development rights or changes of use may not pass the test of reasonableness or necessity. The scope of such conditions needs to be precisely defined, by reference to the relevant provisions in the Town and Country Planning (General Permitted Development) (England) Order 2015, so that it is clear exactly which rights have been limited or withdrawn.Area-wide or blanket removal of freedoms to carry out small scale domestic and non-domestic alterations that would otherwise not require an application for planning permission are unlikely to meet the tests of reasonableness and necessity. The local planning authority also has powers under article 4 of the Town and Country Planning (General Permitted Development) (England) Order 2015 to enable them to withdraw permitted development rights across a defined area, where justified.
Will that guidance be sufficient to avoid disputes? I doubt it.
Am I entitled to apply for planning permission simply for Class E use? Given that Parliament now deems changes within class E not be material, why not? How will such applications be determined as against development plan policies which are likely to be at odds with such an approach, and how will CIL be calculated, given that many CIL charging schedules distinguish as between, for instance, retail and office use?
Fourthly, planning permission will still be required for operational works that materially affect the external appearance of the building. To what extent will local planning authorities seek to exert control by that route, as we have sometimes seen with office to residential conversions? How to guard against plainly substandard conversions of shops to offices and of, for instance, units on out of town business parks to shops?
Fifthly, there is going to be much focus on how precisely the General Permitted Development Order operates in relation to the new class. For an initial period, until 31 July 2021, the GPDO will operate as against how the relevant use was categorised before the changes to the Use Classes Order became effective. Are we to expect further changes to the GPDO in the coming period?
Sixthly, quite apart from these planning law constraints, private law constraints imposed by way of, for instance, restrictive covenants and user covenants in leases will still apply.
But, there’s no way round it, class E has huge implications for much of the world around us, from central business district to market town, to out of town retail or business park. It also brings with it, and this is its very point, huge opportunities to allow for adaptation and for entrepreneurship. How is all this going to work out in practice? Will people start using the new freedoms and then find that inevitably in due course the rules tighten again, by which time the horse has bolted, or, that for land owners, they may have unwittingly lost the right to the use which was most valuable in investment terms? E is also for experiment.

PS and for Emily! Happy birthday daughter.
Personal views, et cetera

Hi Simon
An excellent blog post as ever.
You pose the question: ‘Are we to expect further changes to the GPDO in the coming period?’ It’s worth noting that paragraph 7.10 of the explanatory memorandum to the UCO amendement says:
‘A building or use will continue to be subject to any permitted development rights that it was entitled to on or before 31 August 2020. These transitional provisions will remain in place until 31 July 2021 when new, revised permitted development rights will be introduced.’
E is, it seems, also for expectation.

Simon,
E is also for the Eleventh position in which Saints have just finished, which should add even more shine to the Red & White mug standing proudly in your photo!
It is also for the Excellent blog, thank you. Your six points very powerfully highlight the reality of the situation in which these extended rights arise.
