When Permitted Development Does Not Apply

What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply covering thermal performance (Part L, minimum U-value), security standards (Part Q, PAS 24:2022), safety glazing if the door contains glass panels (Part K), and accessibility (Part M for new dwellings). A FENSA or CERTASS-registered installer can self-certify compliance.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Folkestone and Hythe building control or use an approved inspector.
How to Apply in Folkestone and Hythe

If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Folkestone and Hythe. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Very low planning enforcement risk for standard door replacements. The main practical risk is installing a door without Building Regulations compliance, which creates problems during property sales. A FENSA certificate or building control completion certificate is needed.
