Britannia Windows - Trusted Local Experts


Britannia Windows - Trusted Local Experts

We are a family owned factory with friendly fitters serving Bristol, Clevedon, and the South West. We’ve provided quality double glazing and home improvements such as doors, windows and conservatories since 1982.

You’re in safe hands

Here at Britannia, we are a second generation business with years of experience in creating high quality double glazed windows, doors, conservatories and other home improvement solutions. 

We transform homes across the South East and South West, from our base in Clevedon. Our heart is in the South West, and we opened our first store in Clevedon, just a short drive from Bristol nearly 40 years ago- little did we know then how much the company would grow!  

Across all these years, we’ve developed a knack for high quality work, with even higher quality customer service, so you’ll never need to worry when you’re with Britannia!

We’re here to help you every step of the way
