When should you hire a window and door fitter?
Call a window and door fitter when frames are draughty or rotten, glazing has misted up, security feels weak, or you want to cut noise and heating bills with modern units. Replacement windows and external doors must meet Building Regulations, so the work needs certifying.
How to choose a window and door fitter
Replacement windows and external doors must comply with Building Regulations. Reputable installers are registered with a Competent Person Scheme — FENSA or CERTASS (both UKAS-accredited) — so they can self-certify the work and issue the certificate you will need when you sell your home. Membership of the Glass and Glazing Federation (GGF) is a further quality signal, and it is worth asking for an insurance-backed guarantee on the installation.
What affects the cost
Every job is different, so always get a written quote. The main things that affect the price are:
- Number and size of windows or doors
- Frame material (uPVC, aluminium or timber)
- Glazing specification (double or triple, acoustic, Low-E)
- Access and whether scaffolding is needed
- Like-for-like swap versus structural changes
Frequently asked questions
Do window fitters have to be FENSA registered?
Not necessarily — installers can instead use CERTASS, or arrange a building control inspection. What matters is that the work is certified as meeting Building Regulations, so you get the certificate you need when selling.
Will I get a certificate for new windows?
Yes. A FENSA or CERTASS registered installer issues a compliance certificate after the job, which you should keep with your property documents.
How long do replacement windows take to fit?
A typical house of windows is often completed in one to three days, depending on the number of units and access.
