They go the extra mile
“Had an issue with the weather for the last couple of appointments, which obviously can't be helped, the lads came today on thier day off and completed my new Velux as my old one was leaking really bad.

Kensington
Kensington, one of London’s most prestigious and architecturally rich areas, is home to elegant period townhouses, grand mansion blocks, and luxury modern apartments. With properties in areas like South Kensington, Holland Park, and Earl’s Court often featuring top-floor flats, loft spaces, or rear extensions, Velux roof windows and sun tunnels are a discreet yet effective way to enhance natural light, ventilation, and energy efficiency—while preserving the refined aesthetic typical of Kensington homes.
At Certified Installers Limited, we proudly serve Kensington and the surrounding West London area as certified Velux installers and FENSA-approved professionals. All of our installations comply with UK building regulations and are delivered with the highest standards of craftsmanship.
