About Us

Sash Windows London

Since our opening in 2005, as a family owned professionally managed window company, Sash Windows London has built a reputation for delivering a high standard of customer service and satisfaction. We have built our reputation from local people that trust us and share our values, which is why personal recommendation has always been one of our major sources of new business. Sash Windows London offer a friendly, reliable approach to customer service with highly experienced knowledgeable staff to guide you through every step of the process. Our products have all been designed specifically to suit our customer’s needs, from replicating heritage design in conservation areas to modern, contemporary products to suit today’s market. We are committed to ensuring that high quality remains consistent throughout our entire product range & installation process. We are registered members of FENSA who regulate our installations, and also issue a GGFI 10-year insurance backed guarantee with every installation. We are also registered members of Check-a-Trade, in which our customers submit reports on the quality of their installation to give an honest review of our service. Thanks to all our customers support over the years, Sash Windows London is now the leading installer in the London and Surrey area.
