Safestyle double glazing review

We've surveyed more than 3,000 double glazing customers to find out whether big brands Safestyle, Everest and Anglian are worth spending your money on, especially when pitted against smaller brands and independents. 

Safestyle has been manufacturing and installing windows and doors for more than 25 years, and it says it has completed more than one million installations.

Despite this, though, just over a quarter of customers in our survey said they chose the firm because it had a good reputation – notably less than Anglian and Everest.

The two most common reasons customers told us they chose Safestyle were that it offered a discount, or had particular windows or doors they liked. Our independent research reveals whether customers felt their decision paid off.

Safestyle went into administration in October 2023. It was bought by Anglian Home Improvements, and since January 2024 both businesses are now operating as trading names of the newly formed ASHI Group.

With the casement windows, you can choose from a number of different configurations for the placement of the glass and frames. Decorative glass can also be used in any of the models.

You can choose from bi-fold, French and patio doors. Safestyle's uPVC doors come in the same range of finishes as its windows.

Safestyle double glazing energy efficiency

All of Safestyle's windows are A-rated, and its Legacy sliding sash and EcoDiamond windows are endorsed by the Energy Saving Trust. 

Safestyle triple and secondary glazing

It doesn't sell triple or secondary glazing. Safestyle says its EcoDiamond windows and A-rated sliding sash windows are recommended by the Energy Saving Trust, as they meet recommended energy performance standards.

Safestyle conservatories

Safestyle no longer sells conservatories. If you're thinking of getting one, visit our guide to conservatory prices for all you need to know about buying one.

How long are Safestyle's double-glazed windows and doors guaranteed?

There's a 10-year guarantee for replacement and repair of all faulty windows and doors. Should you move home, this can be transferred to new owners with no charge.

Safestyle is accredited by the Fenestration Self-Assessment Scheme and Glass and Glazing Federation, which means Safestyle installers can self-certify that the double glazing is compliant with building regulations. This saves you having to contact the building control department at your local council yourself.
