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!

Every person was polite and professional, helpful and personable. The process was simple and clearly explained each step of the way. It is rare to get such good service, not to mention the quality of the products. I am very pleased with the windows, the fitting, the price and the experience as a whole. I would happily recommend Britannia Windows.
From the salesman to the office staff and fitters, everyone was thoroughly pleasant and helpful so an excellent experience all around. I'm very pleased with the windows too, they look great. Would recommend without hesitation.

Great job of our new front door. They couldn’t have been more helpful and even fitted earlier originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.
