How we approach sliding rooflights in Towcester
Our sliding rooflights service in Towcester covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Sliding rooflights suit staircases that rise to a roof terrace.
We work across Northamptonshire, including Towcester, and in neighbouring towns such as Northampton and Daventry. Access, parking and how the glass reaches the roof are all checked at the survey.

Things we check at survey

Planning, building control and Towcester
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.
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.
Read the planning permission guide before you commit to a design.
