How we approach electric opening rooflights in Clapham
Electric opening rooflights in Clapham means hinged rooflights that open on an electric actuator for fresh air. We cover the SW4 district and the rest of Greater London, with a survey before any price is fixed.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of electric opening rooflights for rooms that overheat in summer or steam up when cooking.
Clapham is around 5 km from central London, and we survey and fit throughout that part of Greater London, including the SW4 district.
Options we can specify in Clapham

Things we check at survey
- Needs a power supply at the opening — plan the cable route before ceilings close up
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Planning, building control and Clapham
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. 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.

Questions about electric opening rooflights in Clapham
Is it noisy?
Actuators run for a few seconds and are about as loud as an electric blind. Once closed, an opening unit is as quiet as a fixed one.
Can I control it from my phone?
Some ranges link to smart-home hubs or their own app. If that matters, say so at survey and we will specify a compatible model.
Does it need an electrician?
The rooflight wiring needs a suitable supply. We can arrange it, or your own electrician can provide the spur and we connect the unit.
Will I need planning permission in Clapham?
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.
Is the survey in Clapham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
