Anglian double glazing company review

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 3,409 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 research shows that Anglian is the company that consumers most commonly consider when choosing where to buy their double glazing. A quarter of those who contemplated a different company to the one they ultimately chose considered Anglian.

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

Anglian customer comments and ratings

Our customer scores give a good overall idea of what people think of the brand. They are calculated by combining how satisfied people are with a brand and whether they would recommend it.

Our star ratings enable us to dig deeper into what elements of the sales and installation process are working, and failing, for each of the companies in our survey.

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. 

We also ask the customers we survey for comments on the firm they used. These comments reveal exactly what they think about their experience of buying double glazing from that particular firm.

Our research shows that half of those who responded to our survey chose a local or independent double glazing firm or trader. So besides rating seven of the biggest nationwide and regional firms, we’ve created a dedicated advice guide for buying from an independent double glazing company.
