How we approach electric opening rooflights in Bexleyheath
For Bexleyheath homes and buildings we offer electric opening rooflights: hinged rooflights that open on an electric actuator for fresh air. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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. In Bexleyheath, as anywhere, electric opening rooflights are the usual choice for kitchens, bathrooms and bedrooms that need fresh air as well as light.
We work across Greater London, including Bexleyheath, and in neighbouring towns such as Welling and Bexley. Access, parking and how the glass reaches the roof are all checked at the survey.

- Needs a power supply at the opening — plan the cable route before ceilings close up
Planning, building control and Bexleyheath
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Questions about electric opening rooflights in Bexleyheath
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.
Do I need to be at home for the survey in Bexleyheath?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Bexleyheath?
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.
