A few essentials to get you started. For more, see our full FAQ guide.
Is Double Glazing Hub an installer?
No. We’re an independent information hub. We publish guides and, when you’re ready, match you with vetted local installers who provide the quotes and carry out any work.
How much does double glazing cost?
It depends on the frame material, glass, number of windows and your home. Rather than quote a figure, our guides explain what drives the price so you can compare quotes fairly. The best way to get an accurate number is a free quote based on a home survey.
Are the quotes really free?
Yes — quotes are free and there’s no obligation to go ahead. You simply compare what installers offer and decide in your own time.
Do you sell my details to lots of companies?
No. Your details are used to match you with suitable local installers for the quotes you asked for, and we contact you about that enquiry. See our privacy policy for the full picture.
