Our Services Explained



If you need to add living space to your property or want to increase the resale value of your home, choose to invest in our high-quality uPVC conservatories. They’re a great way to enjoy your garden all year round, even when the weather gets a little too cold to sit outside. Our conservatories can be made in all sorts of shapes and styles, and used for anything from a dining or lounge area, to a play area for the kids.



Make Britannic Windows & Conservatories your trusted choice for double glazing in Doncaster and have your home or business property fitted with energy-efficient windows approved by the British Fenestration Ratings Council. Our Veka systems undergo strict hotbox testing to ensure they meet the latest BS EN ISO 12567-1 requirements.


Our uPVC windows are of the upmost quality. We manufacture them in-house to strict energy standards, and offer long guarantees on all installations carried out around Barnsley, Doncaster and Rotherham by our NVQ qualified window fitters.

While slightly more expensive than uPVC doors, composite doors offer increased security and a high-end, premium aesthetic. They combine an easy to clean GRP outer skin with a foam inner core, and aluminium-reinforced timber frame. This makes them incredibly durable and long-lasting, and a fantastic long-term investment for both domestic and commercial property owners around Barnsley, Doncaster and Rotherham.



An essential part of your roof lining, fascias and soffits not only help seal your property against the elements, but they play a big part in your property’s curb appeal. We can supply and install high quality fascias and soffits at extremely affordable prices. Like our uPVC windows, uPVC doors and uPVC conservatories, they’re made out of uPVC and are therefore immune to rotting and warping, and will look great for many years to come.



In addition to the supply and installation of new uPVC windows and double glazing, we also repair existing fixtures that have been damaged. So, whether you’ve been the victim of vandalism or an attempted break-in, or merely suffered an unfortunate accident, call in our window fitters to fix the damage at an affordable rate, that you won’t find with other window companies around Barnsley, Doncaster and Rotherham.
