Common questions

Comparing double glazing, answered

How does comparing double glazing companies work?

You share your postcode and a few contact details, and we match you with vetted installers covering your area. Each provides a quote, and you compare them side by side on price, guarantees and workmanship before deciding anything.

Is it free to compare quotes?

Yes — requesting and comparing quotes is free and there is no obligation to go ahead. You only pay if you choose to accept a quote and proceed with that installer.

How many companies will contact me?

We aim to match you with a small number of suitable installers in your area so you have a genuine comparison without being overwhelmed. Any firm will only contact you about the enquiry you made.

What should I check before choosing a firm?

Look at accreditation such as FENSA or CERTASS, the guarantee on offer (including any insurance-backed guarantee), the full written specification, and the deposit and payment terms. Our guides walk through each of these.

Do I have to go ahead after comparing?

No. Comparing is there to help you make an informed choice. You are free to take your time, ask more questions, or decide not to proceed at all.
