Making any kind of purchase needs careful consideration and when it's something as major as replacement windows, you need to make sure that you've really looked around to find the best price and service.

The double glazing and replacement window site helps you choose your windows and supplier by making it easier to find both local companies and the major national companies on one easy to use site.

Use our easy to navigate site to find a double glazing supplier and installer in your local area. You can click on your area of the UK and find a supplier by navigating to your town or postcode or you can use our search option to find a double glazing company in your location.

Once you've found a potential supplier, it's always wise to get more than one quote. Most advisors suggest at least three but you can get as many as you want.

We'd suggest that you try a minimum of one local and one big name or national double glazing company. Compare the prices and specifications of the quotes and make sure you are getting a like-for-like quote for each company to do a similar job.

During a recession, don't forget that you have extra bargaining power so make sure you ask for a discount and/or those free extras. There are some great deals out there if you take the time to look.
