Anglian double glazing company review

Want to know what Anglian's customers think of its double glazing? Our independent double glazing customer survey reveals all - find out if you should buy Anglian double glazing.
Sarah Ingrams

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 is any good?

We've asked 3,467 double glazing customers about their experiences with well-known brands, including Anglian, Everest and Safestyle, to see how they compare to each other, and with independent or local double glazing firms. 

Our independent survey results show that there's a big difference between the double glazing companies. In fact, the first and last-placed companies are nearly 30 percentage points apart.

Anglian customers most commonly chose it because it had a good reputation, sold particular windows or doors they liked or offered a discount. Our unique research reveals how they felt it lived up to their expectations.
