Do I need planning permission to replace windows in Wirral?

For like-for-like replacements in the same material and style, usually not. In conservation areas, changing materials or style may require planning permission. Listed buildings always need consent.

How much does it cost to replace windows?

Window and door replacement in London typically costs between £3,000 and £15,000 depending on the number of windows, material (UPVC, timber, or aluminium), and style.

Do I need Building Regulations for new windows?

Yes. Replacement windows must comply with Building Regulations for thermal performance. FENSA-registered installers can self-certify compliance.

Can I change my windows from timber to UPVC?

In most areas, yes. In conservation areas, the council may require you to keep timber windows. Listed buildings must retain their original window style.

Conservation Areas & Listed Buildings

In conservation areas, changing window materials (e.g. timber to UPVC) or styles may need planning permission. Listed buildings always need Listed Building Consent for any window or door changes.

Conservation areas

Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.

Listed buildings

Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.

Check if your property is in a conservation area or has other planning constraints.
