What About Building Regulations?
Building regulations approval is not usually required
A conservatory is exempt from Building Regulations provided it is at ground level, under 30 square metres, has its own independent heating with separate controls, is separated from the house by external-quality walls, windows, and doors, and any glazing complies with safety glazing requirements. Removing the separating wall or door means Building Regulations apply in full.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Walsall building control or use an approved inspector.
How to Apply in Walsall
If you need planning permission for your conservatory, you can apply through Walsall's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Walsall. 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?
Enforcement risk is the same as for single-storey extensions. Conservatories that breach PD limits can face enforcement notices. Removing the separating wall without Building Regulations approval is a common issue flagged during property sales.
