None at all. Compare quotes at your own pace. You’re only ever committed once you sign an installer’s contract directly — and we recommend you read it carefully before signing.

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.

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.

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.

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.
