Loft conversion skylights in Trowbridge: what is involved?
For Trowbridge homes and buildings we offer loft conversion skylights: roof windows planned for loft rooms — light, headroom and escape. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty. In Trowbridge, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
Neighbouring towns include Melksham (8 km) and Bath (12 km). We offer a survey date when we reply to your enquiry.

Before you order: points to check

Do you need permission in Trowbridge?
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.
