Conservatories South West

Do you remember old conservatories that were freezing in the winter and sweltering in the summer? We don’t sell those. Instead, we curate high-performance glazed extensions that can be designed specifically for your unique needs and space. Talk to us to find out what we can do for your space.

We have invested millions of pounds into our state of the art UK manufacturing facilities, enabling us to provide high quality products at great prices. Our loyal factory workers are well trained and take pride in their work. They really care about conservatories.

High Quality

Our products are tested independently by British Standards. This means that we have to send them to independent test houses in order to be thoroughly tested. Needless to say, we take the quality of our products very seriously indeed.

Glazing Options

We have a wide variety of glazing options for our conservatories, including self-cleaning, noise-reduction, UV filters and much more. Our high-performance glass retains heat in the winter and reflects the worst of the sun’s glare in the summer, so it is a comfortable temperature whatever the season.
We spend the time to understand what you want from your glazed extension so that we can provide a multifunctional space that you can use all year round; for entertaining, relaxing or spending some quality family time. We want your conservatory to be as individual as you are, so just organise a home visit, and we can talk you through all the options available to you.

Roofing Options

Homeowners no longer have to choose between a solid or glass conservatory roof with the hybrid roof, Livinroof. This roof can help you extend your living space and create a comfortable room that’s light, bright and suitable for year-round living.

We can also fit Ultraroof - the high performance, tiled conservatory roof. This roof is the lightest and strongest tiled conservatory roof on the market. It is designed to sit on old or new window frames and doors without ever requiring a tie bar.

With fewer and slimmer bars than other systems, the Ultrasky Lantern has the flexibility to respond to your design aspirations. Whatever style of property you own, the Ultrasky lantern will enhance it.

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.
