Anglian has been selling double glazed windows and doors for more than 50 years. It's a well-established and recognisable company. But does that mean Anglian's double glazing is any good?

We've asked 2,239 double glazing customers to rate the well-known brands Anglian, Everest and Safestyle to see how they compare to each other, and with local independents. 

Our results show a staggering difference between the double glazing companies. In fact, the first and last-placed companies are 30 percentage points apart.

How did Anglian score in our double glazing survey?

The table below shows how Anglian performed across the range of important criteria when buying double glazing and having it installed.

Our customer score, which gives you an overall view of how a brand rates in comparison to others, is based on how satisfied customers are with the company and how likely they are to recommend it to a friend.

We are also able to dig even deeper into what elements of the sales and installation process are working, and which are failing, for each company. To do this, we ask customers to rate a number of factors. This includes the knowledge of staff (both sales and installers), quality of products and installation, and clarity of documentation - such as the contract.

You can use this information, based on the experiences of actual double glazing customers, to help you pick the best double glazing company for your home.
