A building is classified as a particular type of use.
Class C = residential; C1 = Hotel;
Class E – Commercial, Business and Service E; E(b) sale of food and drink for consumption on site
Change of use is classed as development and as such requires planning permission, however planning approval is not required for some changes of use for example, for a pub to a shop. Under the previous and current government administration more permitted development changes of use have been brought in.
A revised General Permitted Development Order was published in 2015
Note: some permitted development rights for eg house extensions may vary within Conservation Areas.
Permitted development rights for change of use from Retail to Residential are not applicable in conservation areas. See part 3 M of the Schedule 2 Permitted development rights
Change of use from Office to Residential is permitted change of use in Conservation areas (not for Listed buildings) but an application has to be made to cover certain aspects of the proposed development, transport, contamination and flooding See part 3 O of Schedule 2 Permitted development rights
Prior Approval applications are for Permitted Developments and cover the aspects of development set out above.

Class MA: permitted development right:
“The new PD right, and other changes to the PD system, were introduced via new regulations laid by the Ministry of Housing, Communities and Local Government (MHCLG) last Wednesday, the Town and Country Planning (General Permitted Development etc.) (England) (Amendment) Order 2021. Here are 12 things you need to know about the revisions.
- The new class MA PD right allowing a range of commercial uses to convert to housing without needing a planning application will be introduced on 1 August. It covers a range of uses in the new class E use class, including offices, shops, restaurants, cafes, health services, nurseries, gyms and leisure uses. Of the above uses, shops and offices are already subject to other residential conversion PD rights (see next point). An explanatory memorandum accompanying the changes states that applications for prior approval under Class MA “may therefore only be submitted on or after 1 August 2021”.
- The new class MA PD right replaces two existing commercial-to-residential PD rights, including the controversial office to residential right. The latter, called class O, was introduced in 2013 and the government says has “delivered over 72,000 homes in the five years ending March 2020”. It will also replace the class M right allowing A1 shops and A2 financial and professional services to convert to residential. The memorandum states that the “existing rights for the change of use from offices and from retail to residential will continue to apply until 31 July 2021” but the legislation prevents applications for prior approval for under these two rights being made after 31 July 2021. The class M right also allows the conversion of take-aways, betting offices, pay day loan shops and launderettes, which will not be allowed under class MA.
- The government has placed limits on the size of the buildings that can be converted. Buildings with over 1,500 square metres of floorspace will be exempt from the new rules, the statement said, to “focus the right on medium sized high street sites which are more likely to be suitable for conversion”. This is a change on the consultation proposals which had said that no size limit would be in place. According to the MHCLG memo, the change is “in response to comments received”. The current class O right places no limit on the size of buildings to be converted.
- A three-month vacancy requirement has been introduced. Applicants will need to show that the class E building has been “vacant for three continuous months immediately before the date of application for prior approval”. The MHCLG memo says that it has introduced this consideration in response to “concerns raised” during the consultation about “the impact on thriving business”. It adds: “The time that the premises is closed as a result of Government Covid-19 restrictions will not count towards this period where the building continues to be occupied by the owner or tenant.”
- Applicants will also need to demonstrate that it has been in the correct commercial usage for at least two years. They will need to show it has been in class E use for at least two years before the application “in order to prevent gaming”. Because class E was only introduced last autumn, “time served in the uses in former use classes now within the Commercial Business and Service use class, such as A1 (shops), and D1 (b) (non-residential institutions – crèche, day nursery or day centre), will count towards this period”, says the memorandum.
- The prior approval process adds new considerations aiming to protect health centres, nurseries and conservation areas. The right will be subject to prior approval by the local authority in respect of: flooding; transport impacts; contamination; adequate natural light; noise “from existing commercial premises”; and the “impact on future residents from introduction of residential use in an area the authority considers is important for heavy industry, waste management, storage and distribution”. In addition, councils will be able to consider the impact of the loss of health centres and registered children’s nurseries on the provision of local services. The MHCLG memo says it has introduced this consideration in response to “concerns raised” during the consulation about “the potential loss of services like health centres”. In conservation areas, a further consideration is the “impact of the loss of ground floor commercial, business and service use on the character and sustainability” of the area. The memo adds that “separate legislation later in the year will amend the right to introduce an additional prior approval in relation to the fire safety of the building changing use”.
- National parks, areas of outstanding natural beauty (AONBs) and sites of special scientific interest will be exempt from the right. However, it will apply in conservation areas (see point above).
- Article 4 directions exempting areas from current commercial-to-residential PD rights will be allowed to continue for another year. The regulations confirm that any Article 4 directions which currently restrict office-to-residential or retail-to-residential changes will still be in force until the end of July 2022, rather than expiring on 1 August, as many experts had feared. More details here.
- Councils will be able to charge a fee of £100 per home under the new PD right, up to a maximum level of £5,000. The fee “will be introduced via separate secondary legislation at the first available opportunity”, says the MHCLG memo. Currently, £96 is the fee for a prior approval application under class O.
- PD rights for schools, colleges, universities, hospitals and prisons are amended to allow such buildings to expand to a greater extent. The changes to class M of the General Permitted Development Order (GPDO) increase the threshold of the footprint and height these “public service buildings” can increase to under the PD rights. A special prior approval process specifically for university buildings has been introduced “that will allow for local consideration of the impact on design, heritage and archaeology, and highways and transport”, says the MHCLG memo. More details here.
- The new regulations change planning rules around the removal of statues and other monuments. An amendment to class B of the GPDO exempts “statues, memorials and monuments from the permitted development right for the demolition of buildings”. It applies to such structures that “have been in place for at least ten years on the date of proposed demolition” so that in future, proposals to demolish them “will require an application for planning permission”. More details here.
- The new regulations expand PD rights for ports with the changes coming into force on 21 April. The change to class B of the GPDO allow a greater range of buildings to be erected without needing a planning application, bringing the rights into line with those for airports. However, a requirement to consult the local authority would also be included. More details here.”
Permitted development orders:
- size of side and rear extensions, quantum of retained garden, height depending on proximity to boundary
- garage conversion, loft conversion, additional storeys
