Sliding rooflights in Northampton: what is involved?
Our sliding rooflights service in Northampton 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.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Think of sliding rooflights for staircases that rise to a roof terrace.
Northampton is the main town we list in Northamptonshire; we also cover nearby Wellingborough and Towcester.

Do you need permission in Northampton?
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. 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.
