Maidstone
Maidstone, the county town of Kent, offers a diverse range of property styles—from charming period cottages and Victorian terraces to modern family homes and countryside developments. In areas like Bearsted, Allington, and Penenden Heath, many homes feature loft conversions, rear extensions, or underutilised interior spaces that can benefit from more natural light and better airflow. Velux roof windows and sun tunnels are a perfect solution—enhancing the brightness, energy efficiency, and overall comfort of your home.
At Certified Installers Limited, we proudly serve Maidstone and the surrounding Kent area as certified Velux installers and FENSA-approved professionals. This ensures that every installation we carry out complies with UK building regulations and is completed to the highest standard. Whether you're installing a brand-new Velux window, replacing an older unit, or adding a sun tunnel to illuminate a dark corridor or loft space, our expert team provides dependable, regulation-compliant service across Maidstone. For trusted Velux solutions, choose Certified Installers Limited for expert results that last.
