How to get triple glazing quotes
The only way to know what triple glazing would really cost for your home is to compare quotes from more than one installer. This guide shows you how to request quotes online, what to ask for so you can compare like for like, and how our free matching service works.
Why compare more than one quote?
Window prices vary between installers for the same job, and specifications differ too. Getting two or three quotes lets you see the genuine range, spot anything unusually high or low, and negotiate with confidence. It also helps you check that each firm is offering the same frame, glass and guarantee before you compare on price.
What to ask for on every quote
To compare fairly, ask each installer to state:
- The whole-window U-value, not just the centre-pane figure — see our U-values guide.
- The frame material and the glass specification, including any acoustic or low-emissivity glass.
- The guarantee length and whether it is insurance-backed.
- Whether the installer is registered with FENSA or CERTASS.
- The total price, including fitting, VAT and making good.

What to look for in an installer
- Vetted, accredited local installers — not random cold-callers.
- FENSA or CERTASS registration and insurance-backed guarantees.
- Deposit protection and a clear written quote before you commit.
- Free, no-obligation quotes — compare and walk away if it is not right.
Paying for your windows
Once you have your quotes, think about how you want to pay. Many installers offer finance, and funding or contribution options may be available for those who qualify, subject to eligibility and a home survey. If you are weighing up the options, it is worth reading about spreading the cost of a glazing upgrade before you decide. Our cost guide explains what drives the price, and the double vs triple comparison helps you decide which specification to quote for.

Once the quotes arrive, lay them out together and compare on equal terms: the same frame material, the same glass specification and U-value, the same guarantee. If one is much cheaper, check what has been left out rather than assuming it is a bargain. Take your time — a good installer will give you a written quote with no pressure to decide on the spot, and you are free to walk away.
Quotes matched through this site are free and carry no obligation. Any figures discussed are typical ranges; your final price is confirmed by a home survey.
