Class G – Class E or Betting Office or Payday Loan Shop to Mixed use

When Class G cannot be used: The result must remain a qualifying mixed use with no more than two flats, not an entirely residential building. Part of the commercial use must occupy a floor below the lowest flat. Where the building has a ground-floor display window, none of the ground floor can become a flat. The flats must meet the residential-occupation restriction in G.1(c), and prior approval must be dealt with before work begins. The council assesses contamination, flooding, commercial noise, natural light and domestic-waste arrangements, not every aspect of a full planning application.


Class G
is a useful permitted development right for as long as you meet a few minor conditions you can do this anywhere within England subject to Prior Approval. This works well for anything in Use Class E, betting office or pay day loan shop which are both Sui Generis. Use Class E includes offices, shops, banks, gyms, restaurants, GPs, light industrial amongst others. So a wide range of opportunities. Unlike other permitted development rights for conversion to residential there isn’t any date stamp. In theory it could be a virtually new building.

 

Class G

 

Ancillary Use Upstairs

 

First establish whether the proposed upper floor is part of the lawful commercial planning unit. Upstairs storage, staff rooms or offices may be ancillary to the shop or other commercial use below, but physical location alone does not prove that. An independent planning unit upstairs cannot simply be assumed to qualify. Class G also requires an ongoing qualifying non-residential use below the new flats and imposes specific ground-floor and occupation restrictions.

 

Prior Approval Required

 

In August 2021 Class G was altered to required the need for a Prior Approval application to be submitted to the local authority. The proposals will be assessed against contamination, flood risk, impacts of noise from commercial premises, natural light to all habitable rooms and the storage of domestic waste. There is no assessment against noise from the highway.

One item that might cause issues is the storage of bins for domestic waste or the placing of them on the road to not obstruct others. This must be dealt with in the application.

Provide a credible, site-specific strategy for domestic waste storage and collection. Do not assume a universal 25-metre carrying distance or that bins may automatically be stored on the highway. The acceptable arrangement depends on the collection authority, highway conditions and the particular site. This appeal decision is an example of the treatment of waste arrangements, not a general statutory exemption.

If there is not a suitable location, then the possibility of an on-site management company moving the bins to/from the main road might be an option if the drag distance is too far. This distance might be in the local plan.  Do not ignore this part as this is where a refusal might take place.

Note that transport and parking is not a matter for consideration, unlike Class MA.

Noise from existing commercial properties might be an issue depending upon the location. Therefore a Noise Assessment might be required. This should not include highways.

Application Form

 

You can download the application form directly from the planning portal here. You will need to submit it to the local authority directly and pay the relevant application fee. See our planning application fees page for the current amount.

 

What does “Mixed Use” mean?

 

Quite simply it means that you can have up to two flats above shops under permitted development. You must have the flats above the commercial element and you can’t convert part of the ground floor into a flat.

That’s about it on Class G – it is not restricted in any location such as conservation areas, national parks, listed buildings etc. Although for a listed building you will require listed building consent. The only requirement is that the area above should be connected to the commercial unit below in some way or in other words ancillary.

If the shop is large enough why not consider splitting the shop. Once you have split the building down the middle or into more segments from top to bottom you can create up to two flats above each of the shops. How good is that?

If the commercial unit has been in existence for two years you might be able to combine Class G with Class MA. You should also be able to combine it with Class L upstairs. But please ensure you complete Class G before attempting to convert the commercial unit below.

It was held in Valentino Plus Limited v. Secretary of State for Communities and Local Government [2015] EWHC 19 (Admin) that a proper interpretation of Class F (a previous incarnation of what is now Class G) “permits a change from a single planning unit to up to three planning units, that is to say one in A1 (now E) use and two flats” (paragraph 17 of the judgment). This gives extra weight to the ability to use Class L to convert to an HMO.

However as every circumstance could be different, the person considering applying Class L rights must asses as to whether their property is legally able to go from C3 to C4 having previously benefited from Class G change of use or indeed any other legislation. Of course, these rights may also be prevented via an Article 4 or other restrictions placed on the property.

When Class G is not available

The starting point must be a lawful Class E use, betting office or payday loan shop. The new arrangement must be a qualifying mixed use containing no more than two flats and an ongoing commercial use, not the conversion of the whole property into residential accommodation. The Class G conditions require some of the commercial accommodation to remain on a floor below the lowest part used as a flat. If there is a ground-floor display window, no part of that ground floor may become a flat.

It is important to check the lawful planning unit before commissioning drawings. An upstairs room described as shop storage might form part of the existing Class E unit, while an independent upstairs dwelling or different planning unit might not. The existing commercial floor space must be genuinely lawful; merely using a room informally for storage does not necessarily establish its planning status. Flats must also comply with the residential-occupation condition in G.1(c).

What can cause prior approval to fail?

The council can consider contamination and flooding risks, noise from nearby commercial premises affecting future occupants, adequate natural light in habitable rooms, and workable storage and management of domestic waste. Bin collections, service yards, neighbouring restaurants and poorly lit deep-plan accommodation therefore deserve attention before an application is submitted.

There is no general Class G right to construct an extension or radically rebuild the premises. Separate operational work may require planning permission, building control approval or listed building consent. Article 4 directions and restrictive planning conditions must also be checked. Where the original commercial use has no lawful right to operate, obtaining Class G prior approval will not cure that underlying problem.

What evidence should you assemble?

Provide dated evidence of the existing lawful use and the relationship between floors, a floor plan identifying retained commercial accommodation and both proposed flats, window locations and elevations, and supporting flood, noise, daylight or waste information where needed. Follow the Paragraph W application procedure rather than assuming that Class G grants permission automatically.

(i) by a single person or by people living together as a family, or
(ii) by not more than 6 residents living together as a single household (including a household where care is provided for residents).

(d) before beginning development, the developer must apply to the local planning authority for a determination as to whether the prior approval of the authority will be required as to—
(i) contamination risks in relation to the building;
(ii) flooding risks in relation to the building;
(iii) impacts of noise from commercial premises on the intended occupiers of the development;
(iv) the provision of adequate natural light in all habitable rooms of the dwellinghouses;
(v) arrangements required for the storage and management of domestic waste.

Interpretation of Class G

G.2 For the purposes of Class G, “care” means personal care for people in need of such care by reason of old age, disablement, past or present dependence on alcohol or drugs or past or present mental disorder.

 

Class G was introduced on 15th April 2015. Until 1st August 2021 it didn’t require prior approval.
Prior to 15th April 2015, it was Class F within the 1995 GPDO. Class F was introduced on 3rd June 1995
