Benchmark Windows


Benchmark Windows Limited was formed at the end of 2010 by the merging of two long established window companies that had previously specialised solely in the trade sector of the double glazing industry.

With over fifty years of combined window industry experience, directors Jason, Pippa and Russ are hoping to fill what they consider to be a rather large gap in the market for a good,new company with a real foundation. A local company with extensive local experience and genuine integrity. A company that has a full range of their products on display in their own showroom.


A Benchmark conservatory is a great way to add space and value to your home. Built to last with the very best products and materials available – you will be delighted at the difference a well designed and crafted glassroom can make to your home and lifestyle.
