Sliding rooflights for Chippenham: the essentials
Sliding rooflights in Chippenham means box rooflights whose glass lid slides back for walk-out roof access. We cover the SN15 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. Sliding rooflights suit staircases that rise to a roof terrace.
Chippenham is around 26 km from Swindon, and we survey and fit throughout that part of Wiltshire, including the SN15 district.

- Integrated balustrade on some ranges
- Box (glazed sides) or flat sliding lid
- Electric drive with safety edge

Before you order: points to check

Planning, building control and Chippenham
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.
