Class E flexibility or a change of use application

Moving from one use to another inside Class E is not development, so it needs no planning application. A shop can become a cafe, a gym, a nursery or an office without asking anybody, because section 55(2)(f) of the Town and Country Planning Act 1990 takes changes within the same use class outside the definition of development. That is the freedom the 2020 amendments to the Use Classes Order created, and it is wider than most occupiers realise.

Three things take it away. A condition on the planning permission that restricts the use. A proposed use that sits outside Class E altogether, usually as sui generis. And an Article 4 direction removing a permitted development right the occupier was relying on. Check all three before signing a lease, because the answer changes what the premises are worth to you.

What movement within Class E is free

Class E, the commercial, business and service class, covers a wide span:

Movement between any of those is outside planning control as a matter of use. The physical works are a separate question, and a shopfront alteration, a flue, a new opening or an air conditioning unit may each need permission in their own right even where the use change does not.

That split catches people out. A gym operator taking a former bank unit needs no consent for the use and may still need consent for the plant on the roof, the acoustic enclosure around it and the signage.

Uses that look like Class E but are sui generis

Several high street uses sit outside the class entirely, so a change to them is development and needs an application. The ones that come up most:

• hot food takeaways, where food is sold for consumption off the premises
• pubs and drinking establishments, including those with expanded food provision
• cinemas, concert halls, live music venues, theatres, bingo halls and dance halls
• betting offices and casinos
• launderettes
• vehicle hire, sale or repair premises and petrol filling stations
• nightclubs and amusement arcades

The takeaway case is the one that generates most trouble, because the line between a cafe in E(b) and a takeaway in sui generis turns on where the food is consumed rather than on the shopfront. An operator selling mostly to walk-out customers from premises with a few tables is on the wrong side of it, whatever the lease says.

Places of worship and community halls sit in Class F1 and F2 rather than E, so a change from a shop to a place of worship needs permission. So does a change to a small local convenience shop where it falls within F2(a) rather than E(a), which is a distinction that depends on floorspace and on whether another such facility exists nearby.

Conditions on an existing permission that override the class

A condition is the most common reason the Class E freedom does not apply. A permission granted with a condition requiring the premises to be used "as a retail shop and for no other purpose" removes movement within the class, and the Court of Appeal has confirmed that clear words excluding other uses are effective.

Two practical points follow. Read the whole planning history rather than only the most recent decision, because the restrictive condition may sit on a permission from twenty years ago that is still the operative consent. And remember that where a permission predates 1 September 2020, references in its conditions to the old use classes continue to be read as references to those old classes under the transitional provisions in the 2020 Regulations.

Where a condition blocks the use you want, the route is an application under section 73 to vary or remove it. That is a different exercise from a change of use application and it is usually quicker, and the choice between the mechanisms available is set out in the comparison of section 73 against section 96A for changing a scheme.

Evidence of the lawful existing use

You cannot move within a class unless you know which class you are starting from. On older premises that is a question of fact and it needs evidence: the planning history, business rates records, trading accounts, photographs, tenancy documents and, where the use has changed without permission, proof of how long the current use has run.

Where the position is unclear, a certificate of lawfulness of existing use or development under section 191 of the Town and Country Planning Act 1990 settles it. A lawful development certificate is the only formal way to confirm that a use is lawful, and it costs a fee and some weeks against the risk of taking a lease on premises whose lawful use is something you did not expect.

When an application is unavoidable

Four situations put you back in the application system:

1. The proposed use is sui generis or falls in F1 or F2
2. A condition restricts the use and has not been removed
3. An Article 4 direction removes the permitted development right you were relying on
4. The works needed to deliver the use require permission, regardless of the use question

Where an application is needed, the supporting documents follow the impacts. A hot food use will need extraction and odour evidence, and the Ventilation and Extraction Statement page sets out what that covers. A late-opening use or one with plant will need a Noise Impact Assessment addressing plant noise and customer activity against the background level. Parking and servicing evidence follows where the trip pattern changes.

Article 4 directions affecting Class E

Article 4 directions do not remove the within-class freedom, because that freedom comes from the Act rather than from permitted development rights. What they remove is the rights the Order grants to move out of Class E, most commonly the commercial to residential route, which many authorities have restricted in town centres and employment areas.

So check the authority's Article 4 register for the specific address. The directions are site-specific or area-specific, often drawn tightly around a shopping frontage, and a unit two doors down may be treated differently.

Checking before you sign a lease

Five enquiries, in this order:

• the planning history of the unit, with every condition read
• the lawful existing use and the evidence supporting it
• whether an Article 4 direction applies to that address
• whether the works you need require permission in their own right
• whether the landlord's permitted use clause matches what planning allows

The last one is a lease problem rather than a planning problem, and it is regularly the one that bites.

Budget time as well as fees. A section 73 application or a change of use application runs to eight weeks when it goes smoothly, and a lease with a short rent-free period will not absorb that comfortably.

A Planning Statement drafted on PlanScope sets out the use class analysis, the condition position and the impact sections for a change of use application, with the local policy references structured for the officer. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
