Composite Windows UK specialise in high-end composite, timber and aluminium windows and doors.
We have partnered with the DOVISTA Group to offer both Rationel and VELFAC brands. We also supply Solarlux folding and sliding doors, glazed extensions and Spitfire entrance doors.
Both the VELFAC and Rationel composite product ranges bring together the best of both worlds. They offer the durability and versatility of aluminium, together with the beauty and warmth of natural wood.
Rationel windows and doors are also available as fully timber product. All Rationel windows and doors have an iconic Scandinavian design that’s driven by detail. The result is something that truly stands out from the rest.

What Our Clients Say

Westcott installed Velfac aluminium windows, bi-folds and external doors right across our house refurb. They were friendly, responsive and knowledgeable – and explained things in terms we could easily understand. We have no hesitation in recommending Westcott.
Chandra, Hove
I have had Velfac windows and external doors for 12 years. One window was not fitted properly by the developer (not Westcott) and had been leaking and needed replacing. The window was on a 4th floor flat and access difficult. Westcott were recommended by Dovista and Westcott worked timely from survey to order and then to sync with scaffolders dates to install. The guys had difficulty getting the frame up to 4th floor but they stripped it down and hoisted it up to the 4th floor. The job was professionally completed in a day. I am very pleased with the result and would recommend Westcott. Particular thanks to the boys who were all courteous and professional- Adam, Gavin, Matt and Andy. The office staff were always prompt with replies too. Thank you all.
Anthony, Cosham
I have had the pleasure of working with Jeremy and his team on numerous occasions and find them all to work to the highest standards and with the upmost professionalism. Having 25years experience in the building trade as a plasterer myself I have experienced good and bad companies along the way. However Westcott Construction is up there with the best of them and I couldn’t recommend them more highly than I do.
