What does skylight replacement in Gloucester involve?
Thinking about skylight replacement in Gloucester? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Skylight replacement suits older extensions due a modern rooflight.
We cover all of Gloucester and the GL1 district, and nearby Cheltenham and Stroud.

Planning and building rules for Gloucester
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
