What Is A Change Of Use Planning Application?

A change of use planning application is a formal request submitted to your local council to authorise a change in the way a building or part of a building is used. Under the UK planning system, every property falls into a specific “use class” (like retail, restaurant, office, or residential). If you want to use premises for something different from its current use class, you’ll often need official approval before making the switch-even if no building work is involved.

Why does this matter for your business? Simple: trading without the correct use permissions can lead to enforcement action, business disruption, or even forced closure. So getting your change approved early is a must.

Why Might My Business Need A Change Of Use Planning Application?

Most UK businesses will need a change of use planning application if:

• You’re opening a new business in a building previously used for a different purpose (e.g. turning a bakery into a bar).
• You want to add new services-like serving food and drink at a venue previously used as a shop (which may not be permitted without approval).
• You’re converting offices into residential flats, or vice versa.
• You want to expand into additional areas (e.g. making a retail space partly a café).

If you’re unsure, it’s always worth checking with your local planning authority. Even subtle changes-like adding takeaway to a café-can trigger a change of use requirement.

How Do Use Classes Work In The UK?

The government classifies types of property use into “use classes” under the Use Classes Order 1987 (as amended). The main use classes for business are:

• Class E: Shops, cafés, restaurants, offices, gyms, nurseries and more.
• Sui Generis: Certain uses that don’t fit a class (like takeaways, pubs, nightclubs, cinemas, or betting shops).
• Other Classes: Residential (Class C), assembly/leisure (Class F), industrial (Class B), etc.

In 2020, the government restructured the classes so that some changes (like shop to restaurant, both now under Class E) don’t always require formal planning applications. However, moving to or from sui generis or residential uses generally still does require council permission.

Do I Always Need A Change Of Use Planning Application?

Not every change of business activity needs a formal planning application. Some small changes within the same use class may be done without permission (this is called “permitted development”). For example:

• Switching from a shop to a café may be possible if both fall under Class E (but check if late hours or alcohol are involved-these can still trigger applications).
• Adding workspace desks into a retail store may be fine within mixed commercial use.

However, if you want to:

• Convert a retail unit into residential accommodation, or vice versa
• Open a takeaway (sui generis) in a former convenience store (Class E)
• Turn an office into a music venue or gym

…then you’ll almost certainly need a change of use planning application.

The best way to confirm is to check local licensing requirements and contact your council.

What Is The Process For Getting A Change Of Use Approved?

Here’s a step-by-step guide to the typical process:

1. Research The Current Use Class

Before making plans, confirm the building’s current use class. You can find this information through your council’s planning department or the last planning permission granted.

2. Assess Your Proposed Use

Compare your business idea to the existing use. If your proposal is a different class, you’ll probably need to apply.

3. Check Local Policies

Some councils have strict rules about what uses are allowed in certain areas. For example, they may restrict the number of takeaways, protect retail on high streets, or control late-night venues.

4. Prepare Your Application

An application usually includes:

• Correct application form (found on the council’s website)
• Supporting documents: a business plan summary, location map, site plan, floor plans, and a statement explaining the change
• Application fee (varies by council and property)

5. Submit The Application

Apply online through the Planning Portal or your council’s planning system. You’ll likely receive an acknowledgement and reference number.

6. Wait For Consultation And Decision

The council will notify neighbours, consider comments, and assess policies. Expect a decision within 8 weeks-though it can be longer for complex cases.

7. Possible Conditions Or Refusal

If approved, the council may set conditions (like operating hours or noise limits). If refused, you can revise your proposal or appeal.

What Legal Risks Should Businesses Watch For?

It’s crucial to follow the legal process for a change of use planning application. Trading under the wrong use or before getting approval exposes your business to several risks:

• Enforcement notices: The council can order you to stop trading or revert the property to its previous use.
• Fines or prosecution: Persistent breaches can be prosecuted under the Town and Country Planning Act 1990.
• Landlord disputes: Changing property use without landlord permission can breach your commercial lease or licence agreement.
• Problems selling or assigning your lease: Unauthorised changes may make the property less attractive to buyers or future tenants.

Setting up your legal compliance early saves you from expensive mistakes and lost business down the line. Be proactive and don’t risk it.

Does My Business Need Other Permissions Or Licences?

Depending on your new business activity, you may need other licences or consents on top of your change of use planning application:

• Alcohol Licence: Serving alcohol requires a premises licence.
• Food Business Registration: If you’ll be preparing or selling food, you’ll need to register with the local authority. Learn more from our food licence guide.
• Building Regulation Approval: Any physical changes to the property might need separate approval for safety.
• Signage Consent: New external signs usually need advertisement consent.
• Music or Entertainment Licence: Public performances, live music, or showing films often require extra permissions.

Missing out on these requirements-even if you have planning approval-can lead to legal headaches. Make sure you check all necessary licences before opening the doors.

What Legal Documents Do I Need Before Changing Use?

Anytime you change your business activity or use of a property, having the right legal paperwork is as important as council approval. Key documents to consider include:

• Commercial Lease or Licence Agreement: This should clearly permit your intended use and spell out responsibilities for compliance and insurance. See our café and restaurant lease guide.
• Planning Consent/Decision Notice: Keep a copy as proof of your approved use-you’ll need it for future licence applications, lease renewals, or sales.
• Supplier Contracts: Make sure new activities and goods are covered by written terms with suppliers and service providers.
• Health & Safety, Data Protection Policies: Update or create policies reflecting your new activities (especially if you’re moving into catering, hospitality, or have new customer data).

Avoid using generic templates-tailored, well-drafted contracts will protect your business from disputes and liabilities as it grows. Our guide on secure contracts explains why this matters.

What Are Some Common Mistakes To Avoid?

Change of use planning applications can trip up business owners if you don’t cover all the bases. Watch out for these pitfalls:

• Trading before approval: Don’t start operating until you have written consent. Acting early risks fines and even closure.
• Assuming permission isn’t needed: Always check, even if your activities seem similar to the previous business. Councils interpret “change of use” differently based on local policy.
• Ignoring lease restrictions: Landlords can block changes or even terminate the lease if you breach the permitted use clause.
• Only receiving verbal/not written guarantees: Get all permissions (landlord, council, other regulators) in writing.
• Missing extra licences: Just because you’ve got change of use approval doesn’t mean you’re legally allowed to carry out all new activities. Always check for secondary licences.
• Undervaluing professional advice: Getting a legal expert involved early can flag risks and save you costly mistakes.
