Use Classes and Change of Use – Page 11

Evidence pack for a change of use application

Change of use applications stall at validation more often than they fail on planning merits. The documents that prove the existing use and answer environmental health first.

Offices to laboratories: Class E flexibility in practice

Offices and research and development both sit within Class E(g), so the use change is not development. The old occupancy condition and the rooftop plant are what need an application.

Delivery-only kitchens: which use class applies

A delivery-only kitchen has no counter and no customers, which is why the use class question has no settled answer. The application turns on odour, noise and riders.

Agricultural to equestrian: why it is a change of use

Equestrian use falls outside the definition of agriculture in section 336. That single point decides the application, and it also removes agricultural permitted development from the holding.

Conditions that tie a use to one class or occupier

A condition can shut down the flexibility the Use Classes Order gives you. Here is how to spot one on a decision notice, when it is lawful, and the routes to getting it lifted.

Abandonment: how a lawful use can be lost

Non-use does not by itself end a lawful use. But condition, duration, intervening use and intention together can, and the loss is permanent.

Enforcement time limits for change of use after the 2023 Act

Which immunity period applies depends on when the breach began. The transitional position matters more than the headline rule, and continuity is what has to be proved.

Certificates of lawfulness for an existing use

A certificate under section 191 settles whether a use is lawful. It is decided on evidence, not planning merits, and the applicant carries the burden.

Intensification: when more of the same becomes a new use

Doing more of what you already lawfully do is not automatically development. The line is crossed when the character of the use changes, and that is an evidence question.

The planning unit: identifying what is being assessed

Choose the wrong planning unit and every subsequent conclusion is wrong with perfect logic. The starting point is the unit of occupation, and it moves when the land is divided.

Ancillary and incidental uses: when a sideline becomes primary

A cafe inside a garden centre needs no permission until it stops being part of the garden centre. The line is character and degree, and councils test it with floorspace, turnover and trips.

Section 55 and when a change of use is not development

Material change of use is a question of fact and degree, decided on the planning unit. Section 55 sets the frame, and the exclusions in subsection 2 do most of the practical work.

Large HMOs of seven or more: sui generis applications

Above six occupiers there is no permitted change and no prior approval, only a full application. The evidence pack, the amenity standards inside, and the parking and refuse arithmetic outside.

Class C4 and the C3 to C4 change: small HMOs

Three to six sharers puts a house in Class C4. Whether you need permission turns on one Article 4 check, and the application after it turns on concentration, amenity and parking evidence.

What single household means in Class C3

Three friends sharing are not a single household, whatever the tenancy says. How section 258 defines the term, where two sharers sit, and where C3(b) ends and Class C2 begins.

C2 and C2A: care homes, hostels and secure institutions

Class C2 covers care homes, hospitals and residential colleges; C2A covers secure institutions. The commercially important line is the one between C2 and C3.

C1, C3 and serviced accommodation: which class applies

Class C1 covers hotels and guest houses, Class C3 covers dwellings occupied as a single household. Where serviced apartments and short lets sit, and how councils decide.

Pubs and drinking establishments outside the use classes

Since September 2020 drinking establishments have sat outside the Use Classes Order entirely. What that means for changing a pub to another use, and the evidence councils expect.

Hot food takeaways: sui generis and the Class E boundary

Where the food is eaten decides the use class. What happens when delivery trade takes over a restaurant, and why the extract duct decides most applications.

Class F2: local shops, halls and the 280 square metre rule

Whether a village shop is Class F2 or Class E turns on floor area, goods sold and what else lies within 1,000 metres. Why that classification protects the use.

Class F1: schools, museums and places of worship

A church can become a museum without permission because both sit in Class F1. What the class covers, what still needs consent, and the policies protecting these uses.

Class E(e) and E(f): clinics, creches and day nurseries

Medical services sit in Class E(e) and creches and day nurseries in E(f). The use change is often free, but conditions, drop-off and play space decide whether it works.

Class E(d) gyms and the F2 community boundary

A gym is Class E(d) and a swimming pool is Class F2, even though both are indoor sport. Which side of the line a facility falls on decides whether a change of use is needed at all.
