Permitted Development Rules for an External Cladding or Rendering
Whether external cladding or rendering needs planning permission depends on the extent of the visual change. Maintenance and repair using similar materials is generally PD. Adding new cladding that significantly alters the appearance of the dwelling may require a planning application, particularly in conservation areas.
Conditions
- 1Like-for-like replacement of existing render or cladding is generally PD
- 2Adding cladding to a previously unclad wall may significantly change the building's appearance
- 3Materials should be appropriate for the area and building style
- 4Check with the LPA if the cladding materially changes the building's external appearance
Size and Dimension Limits
- No specific PD dimensions; the issue is visual impact rather than size
When Permitted Development Does Not Apply
- Listed buildings require listed building consent for any external change
- Conservation areas may restrict changes to external materials
- Article 4 directions can remove PD rights for external changes
- Some cladding materials may have fire safety implications (consult Building Regulations)
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations may apply if the cladding changes the thermal performance of the wall (Part L) or if the cladding system is load-bearing. Fire safety requirements (Part B) apply to cladding materials, particularly for buildings over 18m tall. For standard domestic properties, the main consideration is thermal performance and fire resistance of the chosen materials.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact King's Lynn and West Norfolk building control or use an approved inspector.
How to Apply in King's Lynn and West Norfolk
If you need planning permission for your external cladding or rendering, you can apply through King's Lynn and West Norfolk'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 King's Lynn and West Norfolk. 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?
Moderate risk in conservation areas or for listed buildings. In standard residential areas, enforcement is unlikely for render or minor cladding changes. The council can require removal and reinstatement if the change is unauthorised and materially alters the property's appearance.
