Skylight installation in Melksham: what is involved?
Skylight installation in Melksham means survey, supply and fit — new openings, extensions and fit-only work. We cover the SN12 district and the rest of Wiltshire, with a survey before any price is fixed.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of skylight installation for builders' projects and retrofits into finished roofs.
Melksham sits about 8 km from Trowbridge and 10 km from Chippenham, and we cover the whole SN12 postcode district and the roads in between.

Planning and building rules for Melksham
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight installation in Melksham: questions
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
How do I book a survey in Melksham?
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 Melksham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
