Double glazing in London: what to know

Replacement windows and doors in England must meet the Building Regulations — a U-value of 1.4 W/m²K or a Window Energy Rating of band B, and no worse than the units they replace. A FENSA- or CERTASS-registered installer can self-certify that compliance and register the work, so you get a certificate without arranging building control separately.

When comparing firms in London, check the accreditations each one holds, make sure quotes are like-for-like on frame material and glass specification, and get at least three before you decide. Every listing here is an independent local business, so your enquiry goes straight to the firm.

Double glazing in London — common questions

How much does double glazing cost in London?

As a rough guide, a replacement uPVC casement window is typically around £400–£650 fitted, and a full-house replacement often falls between £4,000 and £8,000 depending on the number of windows, the glass specification and the frame style. Prices vary between firms, so it is worth comparing at least three quotes from installers in London.

Are double glazing installers in London FENSA registered?

Many are. Replacement windows and doors must meet Building Regulations, and a FENSA- or CERTASS-registered installer can self-certify the work and register it for you — so you receive a compliance certificate without arranging building control separately. Each listing shows the accreditations that firm holds.

Do I need building regulations approval for new windows in London?

Replacement windows must meet the Building Regulations, but you usually do not need a separate building control application — a FENSA- or CERTASS-registered installer self-certifies the work. In England the windows must not exceed a U-value of 1.4 W/m²K (or achieve at least a WER band B) and must be no worse than the ones they replace.
