Loft conversion skylights in Marlborough: what is involved?
Loft conversion skylights in Marlborough means roof windows planned for loft rooms — light, headroom and escape. We cover the SN8 district and the rest of Wiltshire, with a survey before any price is fixed.

Do you need permission in Marlborough?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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 Marlborough: questions
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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.
