Permitted Development Rules for Replacing Windows (Like for Like)
Generally permitted. Replacing windows with units of a similar appearance is treated as maintenance and repair. Even changing the frame material (for example, timber to uPVC) is usually PD for standard residential properties, though conservation areas and listed buildings have restrictions.
Conditions
- 1Replacement windows must comply with Building Regulations Part L (energy efficiency)
- 2In conservation areas, changes to window materials, style, or proportions may need PP
- 3Listed buildings require listed building consent for any window changes
- 4Work must be carried out by a FENSA-registered installer or with building control approval
Size and Dimension Limits
- Same openings as existing; no change to wall structure needed for like-for-like replacement
When Permitted Development Does Not Apply
- Listed building consent is needed for all window changes on listed buildings
- Conservation areas may restrict changes from timber to uPVC
- Article 4 directions can remove PD rights for window replacement
- Non-compliant windows (not meeting Part L) cannot be certified and create problems when selling
What About Building Regulations?
Building regulations approval is likely required
Building Regulations approval is required for replacement windows. Part L requires minimum thermal performance (U-value). Part N/Part K covers safety glazing in critical locations. Part Q covers security (PAS 24). Most homeowners use a FENSA or CERTASS-registered installer, who can self-certify compliance without a separate building control application.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact North Warwickshire building control or use an approved inspector.
How to Apply in North Warwickshire
If you need planning permission for your replacing windows (like for like), you can apply through North Warwickshire'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 North Warwickshire. 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?
Low planning enforcement risk for standard replacements. However, windows installed without Building Regulations compliance (no FENSA certificate or building control sign-off) are a common problem flagged during property sales. Solicitors will request evidence of compliance, and the lack of it can delay or prevent a sale.
