Which rules apply in London?

Replacement windows, heating systems and some electrical work are controlled under the Building Regulations. In higher-risk buildings (18 metres or 7 storeys and above, with two or more homes), building work needs Building Safety Regulator approval before it starts unless it is exempt. Most repairs and like-for-like replacements are exempt, but heating systems, fuse boxes and glazing units are not.

What does it cost in London?

Our guide range for uPVC window replacement in London is £5,500–£14,650 per home. That is the UK range of £4,500–£12,000 (published figure) adjusted by a regional cost factor of 1.22 (VOA Rating Cost Guide 2026: inner London 1.17–1.32, outer London 1.08–1.26); figures are before VAT where the source states it. Every job is priced after survey; specification, access and the condition of the homes will move the figure.
