Windows & Doors in Hounslow: what to know

16 windows & doors firms cover Hounslow, across postcode areas including TW. They are all independent local businesses listed in this directory, so your enquiry goes straight to the firm rather than a national lead broker.

Replacement windows and doors in England have to meet the Building Regulations (Approved Document L) — a limiting U-value of 1.4 W/m²K, or a Window Energy Rating of at least band B — and they must be no worse than the units they replace. A FENSA- or CERTASS-registered installer can self-certify that compliance and register the work with your local authority, so you get a certificate without arranging building control separately.

Windows & Doors in Hounslow — common questions

Do I need building regulations approval for new windows in Hounslow?
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 and registers it for you. In England the replacement 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 windows they replace.
How much do new windows and doors cost in Hounslow?
As a rough guide, a replacement uPVC casement window is typically around £400–£650 fitted, a composite front door around £900–£1,500, and a full-house window replacement often falls between £4,000 and £8,000 — depending on the number of openings, the frame material and the glass specification. Comparing three quotes from Hounslow firms is the best way to judge a fair price.
Should my Hounslow installer be FENSA or CERTASS registered?
It is not a legal requirement, but using a FENSA- or CERTASS-registered installer means the work is self-certified for Building Regulations and registered automatically, and you get a compliance certificate you will need when you sell. Each listing shows the accreditations that firm holds so you can check before you enquire.
