Energy Efficient Windows

At Britannia, we don’t think you should compromise on the windows you want. All our products are made in our state of the art factory near Bristol, so we can manufacture the perfect size and style of window to complement your home. At Britannia, quality is an obsession, and we want to make sure that your new windows are the best possible; that’s why we are always at the forefront of innovation in our industry. We use A+ rated glass only, and you can choose between double or triple glazing. The modern uPVC we use is a far cry from the same material used in the 80s. It is elegant, incredibly insulative, and now available in a range of colours and wood finishes if you want something different from the classic white.

Why Choose Britannia?

Thermally Efficient

All of our different window styles are highly energy efficient, so they’ll help your Bristol home to keep itself at a comfortable, steady temperature all year round, without needing constant input from the central heating!

Low Maintenance

No one wants to be stuck at home scrubbing, varnishing, repainting and just generally faffing all the time to keep things looking good. Fortunately, our windows do their part so you don’t have to! The most they’ll ever need from you is a quick wipe with a damp cloth from time to time!

High Security

Our windows are fitted with state of the art security features, including high tech multipoint locking mechanisms, so that you can be assured that your Bristol home is safe and sound, all the time.

Fully Weatherproof

One of the most important considerations with any home improvement project is weather resistance. The British weather can cause a lot of problems if it’s got a way inside after all! That’s why we ensure that all our windows are 100% weatherproofed.

Stylish and Sleek

With sleek frames, ultra slim sightlines, and seemingly endless customisation options, our windows can provide your Bristol home with a serious style boost! You’re sure to be the envy of all your neighbours!

Eco Friendly

Thanks to our high performance double glazing, our windows can improve the energy efficiency of your home. This helps your achieve a smaller carbon footprint!

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.
