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.!!”

Trowbridge
Trowbridge, the county town of Wiltshire, is known for its mix of historic architecture and expanding residential developments—ranging from Georgian townhouses and Victorian terraces to modern family homes and countryside properties. In areas like Hilperton, Paxcroft Mead, and Southwick, many homeowners are enhancing their properties with loft conversions, extensions, or by maximising natural light in darker rooms. Velux roof windows and sun tunnels offer an ideal solution—flooding interior spaces with daylight, improving ventilation, and boosting energy efficiency.
At Certified Installers Limited, we proudly serve Trowbridge and the surrounding Wiltshire area as certified Velux installers and FENSA-approved professionals. All our installations comply with UK building regulations and are completed to the highest standard. Whether you’re fitting a brand-new Velux window, replacing an outdated unit, or installing a sun tunnel to brighten a stairwell or hallway, our experienced team delivers reliable, regulation-compliant service tailored to your home. For trusted Velux installations in Trowbridge, choose Certified Installers Limited for expert craftsmanship and peace of mind.
