Skylights and rooflights in St Austell
SkylightCompany.uk covers St Austell and the surrounding part of Cornwall, from a single roof window in a loft to a glass link or a warehouse roof.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs.
From St Austell to Bodmin, Truro and Newquay, the same survey-first process applies: measure, specify, fix the price, then fit.

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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.
