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.

Exeter
Exeter, a historic city in Devon, is known for its Roman heritage, stunning cathedral, and a wide variety of homes—from traditional stone cottages and Victorian terraces to contemporary townhouses and rural new-builds. In areas such as St Leonard’s, Heavitree, and Alphington, many properties feature loft spaces, extensions, or darker rooms that can be greatly enhanced with Velux roof windows and sun tunnels. These additions help maximise natural light, improve ventilation, and increase energy efficiency—creating brighter, more comfortable living spaces.
At Certified Installers Limited, we proudly serve Exeter and the surrounding Devon region as certified Velux installers and FENSA-approved professionals. Every installation is carried out to meet UK building regulations and delivered with a high standard of workmanship. Whether you're installing a brand-new Velux window, upgrading an older unit, or fitting a sun tunnel to illuminate a hallway or loft, our expert team provides trusted, regulation-compliant service tailored to your home. For reliable Velux installations in Exeter, choose Certified Installers Limited for results that last.
