Class R prior approval scheme
The Classes R prior approval scheme in the UK allows agricultural buildings to be converted to a flexible commercial use without requiring full planning permission, provided certain conditions are met and prior approval is obtained from the local planning authority.
The Class R prior approval scheme aims to support rural economic development by allowing greater flexibility in the use of agricultural buildings, facilitating their conversion to various commercial uses that can benefit the local economy while ensuring that any significant adverse impacts are considered and mitigated.
This streamlined approach reduces the regulatory burden on property owners and encourages the adaptive reuse of agricultural buildings, contributing to sustainable development in rural areas.
Under Class R, agricultural buildings can be converted to the following flexible uses:
- Shops (A1)
- Financial and professional services (A2)
- Restaurants and cafes (A3)
- Business (B1)
- Storage or distribution (B8)
- Hotels (C1)
- Assembly and leisure (D2)
Conditions and limitations:
- The total cumulative floor space that can be converted under Class R must not exceed 500 square meters.
- The building must have been in agricultural use on or before 3 July 2012, or for a period of 10 years before the date development begins.
- Prior approval from the local planning authority is required to assess:
The process for obtaining prior approval involves submitting an application to the local planning authority, which will consider the potential impacts related to transport, noise, contamination, and flooding. If the authority does not respond within the statutory period (typically 56 days), the development is deemed to have prior approval and can proceed.
From May 2024, the Town and Country Planning Amendment Order (General Permitted Development, etc) 2024 comes into effect. Stating 'Class R (agricultural buildings to a flexible commercial use) of Part 3 (changes of use) is amended as follows. (2) For paragraph R (permitted development) substitute—'
“Permitted development R. Development consisting of a change of use of a building and any land within its curtilage from a use as an agricultural building to a flexible use—
- (a) falling within one of the following provisions of the Use Classes Order—
- (i)Class B2 (general industrial) of Schedule 1;
- (ii)Class B8 (storage or distribution) of Schedule1;
- (iii)Class C1 (hotels) of Schedule 1;
- (iv)Class E (commercial, business or service) of Schedule 2; or
- (v)Class F.2(c) (outdoor sport or recreation) of Schedule 2; or
- (b) for the provision of agricultural training.”.
(3) In paragraph R.1 (development not permitted), in sub-paragraph (b), for “500 square metres” substitute “1,000 square metres”.
(4) In paragraph R.2 (conditions), at the end of sub-paragraph (c) insert— “;
- (d) where the site is to be used for general industrial purposes within Class B2, it must only be used for the processing of—
- (i) raw goods, excluding livestock, which are produced on the site and are to be sold on the site, or
