Frequently Asked Questions

What is the difference between planning permission and Permitted Development?

Permitted Development allows certain works without planning permission under the GPDO 2015, provided they meet specific size and design limits. If your project exceeds these limits or falls outside the rules, you must apply for planning permission.

How do I know if my property is in a conservation area?

Check your local planning authority website or contact them directly. Conservation area status restricts certain Permitted Development rights. Many works that would normally be allowed may require planning permission in a conservation area.

What happens if my property is listed?

Listed buildings require Listed Building Consent for most alterations. Even internal changes may need consent. Always check with your local authority before making any changes to a listed building.

What is an Article 4 Direction?

An Article 4 Direction removes certain Permitted Development rights in specific areas. If an Article 4 applies to your property, you may need planning permission for works that would normally be allowed elsewhere.

How much does planning permission cost?

Planning application fees depend on the scale of your project and are set by your local authority. Typical residential applications range from £200 to £1,500. Contact your council for current fees.

How long does planning permission take?

Standard applications take 8 weeks. Some may be decided faster, others may need more time if clarifications are required. Complex projects may take longer.

Do I need Building Regulations approval?

Most construction projects require Building Regulations approval, even if they do not need planning permission. This is separate from planning and ensures work meets safety standards.
