Conservation rooflights in Bristol: the essentials
Conservation rooflights in Bristol means slim, low-profile steel-look rooflights for period and listed roofs. Every quote follows a survey of the roof and the room below.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs.

Planning and building rules in England
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
