The double glazing quote process

Getting a double glazing quote should feel calm and clear, not pressured. This is the hub for every part of the journey — from your first enquiry to the day new windows or doors are fitted. Follow the four stages below and you will know what happens next at every step, and why the price is what it is.

Stage 1 — Enquire

The first step is a short enquiry: your postcode and a few contact details so a local surveyor can be arranged. Requesting a quote is free and there is no obligation to go ahead. A good starting point for a first estimate is an online double glazing quote, which sets expectations before anyone visits your home.

Stage 2 — Survey

A home survey is where an estimate becomes an accurate quote. A surveyor measures each opening, checks access and looks at the condition of the existing frames. This is the stage that removes guesswork, and it is covered in detail in our guide to the survey and final quote. The survey is free and, again, commits you to nothing.

Stage 3 — Quote

After the survey you receive an itemised quote: the specification, what is included and the total, with VAT shown clearly. A fair quote makes it easy to see what you are paying for line by line. Understanding the difference between a fixed price and an estimate helps you read the small print with confidence, and funding or contribution options may be available, subject to eligibility and a home survey.

Stage 4 — Fit

Only once you are happy with the price do you book a fitting date. Fitters remove the old units, install your new windows or doors and tidy up before they leave. If you would like a picture of the day itself, read what to expect on installation day, or see our own quote-to-fitting timeline for realistic lead times.

Comparing quotes fairly

Because the process is standard, the smartest thing you can do is get more than one quote and compare them on the same terms. Check the frame material, the glass specification, the guarantee and whether the price is fixed. For a wider view of how window pricing works across the market, the complete guide to window quotes is a useful companion read, and you can always get a free no-obligation quote to add to your comparison. When you are ready to compare properly, our reviews of the installation partner show what other homeowners experienced.

See it through, stage by stage

Whichever guide you start with, the shape of the journey stays the same: enquire, survey, quote, then fit. Keep that pipeline in mind and every quote you receive becomes easier to read, easier to compare and far less daunting. There is nothing hidden in the process — just four clear stages, each one under your control.
