Typical uPVC windows range from £450–£900 per window installed. A whole-house replacement (8–10 windows) is usually £4,000–£9,000 depending on style and material. Aluminium and composite cost 20–50% more. Our comparison service typically saves 20–40% vs single quotes.

Installers have different overheads, margins, suppliers, and seasonal workloads. National chains carry heavy advertising costs — local FENSA-registered installers often offer identical quality for significantly less. That’s why comparing is essential.

Many of our fitters offer 0% finance or monthly payment plans — new windows from as little as £43/month with no upfront cost. Mention finance in your quote request and we’ll match you with installers that offer it.

FENSA (Fenestration Self-Assessment Scheme) is the UK’s leading certification for replacement window installers. A FENSA certificate proves your install meets building regulations — essential if you sell your house. It also comes with an insurance-backed warranty, so you’re protected if the installer goes out of business.

All installers in our network are verified at sign-up. You can independently check any installer’s FENSA registration at fensa.org.uk or Certass at certass.co.uk.

FENSA-registered installers provide an insurance-backed warranty. If something goes wrong, you’re covered — and you have a formal complaints route via FENSA’s dispute resolution process. Let us know too and we’ll remove any installer who doesn’t meet our standards.

Quotes require homeowner consent because installers need to survey the property. If you’re a tenant, share Findfitter with your landlord — they can get quotes through us.
