Made in Britain

Made in Britain for over 50 years

Everest has been at the forefront of double glazing production in the UK for over 50 years. From the production of our first Aluminium Secondary Glazing in Waltham Abbey, Everest has been dedicated to supporting UK manufacturing. This enables us to keep a close eye on every step of the process and develop our own market-leading technology and processes, from testing and controlling the quality of the raw materials to making sure everyone involved maintains the high production standards that we expect at Everest.

We manufacture with absolute precision every single time

Our locations

Our 2 factories in the UK are based in Sittingbourne in Kent where we produce all our bespoke uPVC Windows and Conservatories and Treherbert in the Upper Rhonda Valley in Wales where we manufacture all our Aluminium and Timber products.

Family means everything

Having been established for so long we're proud that Treherbert and Sittingbourne are close-knit places. Communities where everyone knows everyone and a family atmosphere has prevailed at the factories over the years. Families and friends have worked for us – fathers, mothers, sons, daughters, brothers and cousins. The culture has changed as the times have changed but the warm and friendly feel has remained.

That's why we're proud of
'Made in Britain'
