Loft conversion skylights in Chippenham: what is involved?
Our loft conversion skylights service in Chippenham covers roof windows planned for loft rooms — light, headroom and escape. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Loft conversion skylights suit attic bedrooms, offices and en-suites.
Chippenham sits about 10 km from Melksham and 15 km from Devizes, and we cover the whole SN15 postcode district and the roads in between.

Planning, building control and Chippenham
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.

Loft conversion skylights in Chippenham: questions
Can you work alongside my loft builder?
Yes — we set out and fit the windows to the builder's programme.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
How do I book a survey in Chippenham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Chippenham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
