Double glazing installer

Just 7% of Which? members say they trust double glazing installers

Local independent double glazing companies tend to leave their customers more satisfied than the big national glazing firms, according to a double glazing customer satisfaction survey carried out by Which?.

Just 7% of Which? members say they trust double glazing companies. So, to help you find a trader you can trust, we asked more than 2,500 members who'd had double glazing installed in the last five years to rate the company they'd used for various aspects of their experience, such as quotation process and customer service.

To find out how the likes of Anglian, Everest, Safestyle and Zenith Staybrite score in the survey, see the full results of our double glazing satisfaction survey.

Double glazing prices

More than 40% of Which? members say it's difficult to find good advice on double glazing, and a quarter had no idea how much double glazing should cost before getting quotes.

To help you avoid getting ripped off, we've produced a pricing guide using prices collected from recommended double glazing companies featured on trader recommendation website Which? Local. 

Find out how much you should pay for different sizes of casement windows, sash windows and double glazed doors with our double glazing pricing guide.

Smaller firms cheaper

We also asked some of the national firms to give us their prices. For the two that shared their prices with us – Anglian and Zenith – these were typically higher than those quoted by local traders who responded to the same questionnaire.

Everest and Safestyle declined to share their prices, with Everest saying: 'it's no secret we charge a premium price for our products'.
