Colin's Sash Windows

Colin's Sash Windows

I founded Colin’s Sash Windows in early 2014 to offer affordable uPVC sliding sash windows without the high costs of traditional double glazing installers. With just an iPad, a phone, and an eBay ad, demand quickly grew for our 7-day delivery sash windows at £299. By May 2014, we launched our website and expanded our range, adding Spectus profile sash windows. Today, 40% of our sales come from repeat customers, proving our quality matches or exceeds competitors. In 2024, our sales reached nearly £10m, driven by our uPVC sash windows and rising demand for Heritage aluminium steel-look doors and Aluspace internal doors. We also supply casement windows at unbeatable prices, with fast delivery and online ordering. Our experienced sales team is always ready to assist, ensuring the best prices in the UK.
