What our Customers say
Quick and Reliable
“A first class product, professionally fitted but two very pleasant workers. I had, initially, been very wary of the remote pricing for the work, as a pensioner unused to this style of estimating, but I needn't have worries and a special mention for the lady on the office computer - Lucy - she always responds quickly and does exactly what she says she will do - you can rely on her.!!”

Norwich
Norwich, a historic city in Norfolk, is known for its beautiful medieval architecture, vibrant cultural scene, and diverse range of housing—from centuries-old cottages and Victorian terraces to contemporary developments and rural homes on the city’s outskirts. In areas like Eaton, Thorpe St Andrew, and Hellesdon, many properties feature loft spaces, extensions, or internal rooms that would benefit from more natural light and ventilation. Velux roof windows and sun tunnels offer a smart and stylish solution—bringing light into darker areas while boosting energy efficiency and comfort.
At Certified Installers Limited, we proudly serve homeowners in Norwich and surrounding areas as certified Velux installers and FENSA-approved professionals, ensuring all work is fully compliant with UK building regulations. Whether you're fitting a brand-new Velux window, replacing an older unit, or adding a sun tunnel to a stairwell or hallway, our expert team delivers dependable, high-quality service tailored to your home’s design. For trusted Velux installations in Norwich, choose Certified Installers Limited for long-lasting, regulation-compliant results.
