Change of Use Planning Applications: A Guide for Business Owners and Trades
2026-09-30 · 7 min read
What change of use means, when a UK business needs planning permission to change how a building is used, and how trades and consultants can win change of use projects.
Why change of use matters to business owners
Anyone opening a business, converting a building or expanding into a new use runs into change of use. Get it wrong and the project stops; get it right and everything else - fit-out, recruitment, trading - can proceed.
Understanding the use classes and what is permitted development is the first step in deciding whether an application is needed at all.
How the use classes work in practice
Use classes group land and buildings by activity. Moving within the same class usually needs no permission; moving between classes may need an application or may be allowed under permitted development.
- Shops, cafes and services have distinct classes
- Offices, light industrial and storage sit in their own classes
- Residential conversions from commercial often need permission
- Some changes have automatic permitted development rights, some do not
Building a strong application
A good change of use application answers the concerns a planner will raise before they raise them: parking, noise, traffic, hours of use and impact on neighbours.
Include clear floor plans, a supporting statement explaining the proposal and its benefits, and any specialist reports the site requires. Applications that address concerns up front face far fewer delays.
Where the work comes from for trades and consultants
Change of use projects need drawings, structural advice, fit-out and often a planning consultant to shepherd the application. Trades that spot applications early can quote before competitors know the project exists.
| Project type | Typical professional input | Typical trade input |
|---|---|---|
| Shop to cafe | Planning statement, drawings | Fit-out, services, seating |
| Office to flats | Architect, planners, building control | Conversion, M&E, kitchens |
| House to HMO | Planning, licensing knowledge | Fire doors, partitions, services |
Pitfalls that sink applications
The most common failure is not checking permitted development rights before assuming permission is needed - or assuming it is not, and finding out the hard way. Others include inadequate parking provision, overlooking and noise concerns left unaddressed.
Turning planning activity into a pipeline
Planning applications are public and are submitted every day. Watching the ones that match your skills lets you approach the applicant early, while plans are still forming.
A consistent habit of reviewing new applications in your area builds a pipeline of projects long before they reach a tender.

Frequently Asked Questions
What is change of use planning permission?
It is permission to change how a building or land is used - for example turning a shop into a cafe, an office into flats, or a house into an HMO. Use classes group similar uses, and moving between them may or may not need an application.
When do I need planning permission for change of use?
You need permission when the new use falls outside permitted development rights for the existing use class. Some changes between classes are allowed automatically; others require a full application.
How long does a change of use application take?
Usually eight to thirteen weeks for a straightforward application, longer if there are objections, listed building issues or highways and environmental considerations.
Who can help with a change of use application?
Planning consultants and experienced trades prepare the drawings, statements and supporting reports. Getting the application right first time avoids costly refusals and appeals.
