A big thank you to Jason and his team for their fantastic work! We’ve been working together for quite some time now, and they’ve just completed the installation of triple glazed windows at our Cotswolds barn conversion. The windows look absolutely fabulous — the quality is outstanding, and the attention to detail has been excellent throughout.
The Origin triple glazed triple sliders in particular create a real wow effect and have completely transformed the space.
Looking forward to the next project together!

We are extremely happy with our new windows and door from Associated Windows. The pricing and quote were clear with no hard sell. They managed to get the windows and door installed within our very tight time frame (our fault!) and the finished products are well made and look great. I definitely recommend them as a window/door company!

Outstanding company with a straightforward, honest approach to pricing and customer service. The quote provided was fair and accurate—no inflated numbers followed by sudden discounts. We received expert advice during the window measurement and ordering process, which was handled professionally. Installation was fast, clean, and high-quality. We’ve used this company twice over the past 15 years, and both times they delivered the best combination of price and workmanship.
