Did you know that changing the use of a property isn't always as straightforward as it sounds?
Whether you're converting a commercial building into residential units, transforming an office into a gym, or repurposing a retail space, understanding the Change of Use planning process is essential.
Here's a simple guide to the key steps:
1️⃣ Identify Your Property's Current Use Class
• If your proposed use remains within the same use class (for example, a shop becoming an office within Class E), planning permission is often not required.
• If the new use falls into a different class (such as commercial to residential), planning permission may be necessary.
2️⃣ Check Permitted Development Rights (PDR)
• Some changes of use are allowed under national legislation without a full planning application.
• In certain cases, you'll still need to obtain Prior Approval from the local authority, which may assess factors such as transport impacts, flood risk, noise, and access to natural light.
3️⃣ Prepare and Submit Your Application (if required)
You may need to provide:
• Existing and proposed floor plans
• A site location and layout plan
• Supporting reports (parking, noise, transport, design and access statements, etc.)
• The relevant planning application fee
4️⃣ Await the Decision
• Most applications are determined within 8 weeks.
• Larger or more complex schemes can take up to 13 weeks or longer.
5️⃣ Obtain Building Regulations Approval
Even if planning permission is granted, separate Building Regulations approval may still be required to ensure compliance with structural, fire safety, ventilation, and energy performance standards.
6️⃣ Appeal if Necessary
If your application is refused, you have the right to appeal through the Planning Inspectorate.
