Looking to buy a new conservatory? At Britannia, we offer a wide range of traditional and contemporary conservatories. Whether you’re after a Victorian conservatory, Lean-to conservatory, Edwardian or Georgian conservatory, Gable conservatory, or Lantern Roof conservatory, we can build any style in our state-of-the-art South West factory.
For those who already have a vision in mind, we offer Bespoke conservatories so you’ll never have to worry about your extension matching your tastes. This is a great option if you’re working with a particularly small, large, or strangely shaped space. Plus, if you like certain features of different conservatory styles, this is a fantastic way to bring them together in one design.
Torn between a new conservatory and a full extension? Have you considered a Tiled Roof conservatory? This is a great option if you’re looking for an extension feel and would also like to benefit from the insulative properties of a solid roof conservatory.
Already have a much-loved conservatory but it’s looking a little worse for wear? Consider a full or partial conservatory upgrade to bring your space to life again. Whether you’re noticing draughty corners, a stained roof, or the sun’s UV rays are damaging your furnishings, we can fix your issues or build you a fully functional conservatory replacement.
Is it just your conservatory roof that’s the issue? Take a look at our replacement conservatory roofs and install a new glass, tiled, or Polycarbonate roof that’s up to scratch.
A conservatory should be an integral part of your home, so give it the care and attention it deserves!
Doors don’t last forever. Are yours past their best-before? Whether you’re in need of a new front door, back door, or another exterior door, we have a range of style and material options suitable for any home.
For a sleek, space-maximising door take a look at our Bi-fold doors. If you’re looking for a tough and sturdy option for maximum protection then browse our Composite doors. Just in need of a quality yet cost-effective door replacement? Our PVCu doors might be exactly what you need. If you fancy a homely, country-style door then our Stable doors are an aesthetic choice that’s also perfect for families or homes with pets.
Looking for the best garden or patio door for your home? Choose between a classic French door style to open your home up to your outdoor space or our PVCu or aluminium Patio doors as a sliding alternative to Bi-folds. You can even opt for traditional sliding Patio doors or our popular lift and slide Patio doors.
At Britannia, we make our secure doors at our South West factory, ensuring only the highest quality doors make it into your home. Whatever your priority — be it style, security, or durability — we have a wide selection of door types and finishes to cater to your home’s needs. We’ll help you find your perfect door replacement to stand the test of time.
Still stuck with single glazing? Perhaps your double glazing is getting old? Don’t be let down by the low thermal efficiency of old or poorly functioning windows.
At Britannia, we’re expert installers of high-quality double glazing. We can replace your old windows with draught-proof and insulative panes that will provide better security for your home and lower your energy bills.
Double glazing is made from two panes of glass rather than one. This creates an extra barrier of protection, preventing cold air entering your home and reducing the rate that warm air leaves it. Thermally toughened glass, thick frames, and double glass panels are also harder to break and will improve your home security in one installation. What’s more, we only install A-rated double glazing to equip your home with the highest quality windows possible.
Did you know that installing double glazing can also reduce condensation build-up and noise from the street? Whatever your home type, we have the expertise and experience to install double glazed windows in modern or traditional properties.
In need of efficient yet cost-effective double glazing for your home? Look no further than Britannia. Still after windows with more protection? Ask us about our triple glazing and Super Energy Efficient glazing.

Manufacturing and fitting double glazing in Bristol & the South West since 1982
Britannia is a second-generation business with years of experience in creating high-quality double glazed windows and doors for homes and families across the South West, based in Bristol. 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 how much the company would grow!
We now have showrooms all across the South and South West of England, and we’re still looking to expand. We owe our growth to our dedicated team of professionals, who turn their hands to all the tasks necessary to run a trusted and successful doors, windows and conservatory business.Read more
Geoffrey Rushton founded Britannia Windows in 1982, and the company was underpinned by his passion for ensuring that all the products were manufactured to the highest possible standard. He made sure that he and all his workers had the skill to carry out all installations perfectly, which led the company to grow quickly through word-of-mouth recommendation.
We may have grown a lot since 1982, but however many showrooms we open, and however many tilt and turn windows, patio doors or Victorian conservatories we fit, we ensure our customer service remains as friendly and personable as it always has been. Over the years, we are proud to say we’ve gained a reputation as a trustworthy, honest and reliable company that has one aim – to give you the best quality service and products we can.
We do this by making all our windows, doors and conservatories in our own factories – this way we are completely in charge of all quality control. By making, delivering and fitting our products ourselves, we can ensure that our customers are happy – but it doesn’t just end there. We are constantly innovating, in security, energy efficiency and product design, so that we can reach our ultimate goal; to be Britain’s best and most trusted Home Improvement Business. This means we can serve you better by providing industry-leading products and services.
We will always be indebted to our loyal customers, which is why we never cut corners. We know your home is important to you, and it’s vital that you feel warm, comfortable and safe. Regardless of whether you choose a composite door or a PVCu panel door, we’ll talk you through the process and make sure you are comfortable with your choice. Our consultants are here to advise you, so you can make the right choice – we’ll never push a product on you.
As a company, we are committed to preserving the local environment. We’ve barcoded all of our orders to reduce paper use, we recycle the majority of our in-house materials (including your old windows) and our factory is powered by solar energy. We also offer triple glazing so that you can help save energy in your own home as well.
Our community investment and charitable donations have been core to our beliefs from the earliest days of our business. We believe that a sustainable business is a better business, and we have committed to reduce our impact on the environment and to support healthy communities in the areas we operate in.
From hiring local talent, providing exceptional customer service and making long-term commitments to help the environment around us, we are a nationwide company that has never lost its local touch.
The highest-rated and largest manufacturer of double glazing & home improvement products in Bristol & the South West.

Your happiness is so important to us; that’s why all our sales consultants will greet you with a smile and give you friendly, personable service – no wild promises and no pressure to buy.

Why not contact us today to see how we can make your living space more beautiful, more spacious and personalised to you and your family?
We have an extensive offering of technical window and glass features that can optimise your windows to your space. From sound-proofing to salt corrosion protection, or self-cleaning to UV-filters, just speak to one of our knowledgeable staff members and we can find what is right for you.
Maybe you’re tired of your old sash windows and are looking for an upgrade? We have a wide variety of windows including modern aluminium-framed windows, but we also specialise in heritage windows, so you can have all the performance of a modern window (including double glazing and draught protection) even in a listed house.
There are so many new and innovative window, door and conservatory designs that have recently come on the market, and we make sure we are up to date with all of them. We’re always on the lookout for new, better ways to improve your home, and we’re proud of the high-tech security and energy efficiency features we provide that mark our business as industry leaders.
We don’t expect you to know exactly what type of windows you want, or which front door features you’d like. That’s why we talk you through each stage, step by step, so you understand exactly what you’re getting – and why.
Your home is important to you, which is why we want it to be perfect.
