How we approach electric opening rooflights in Balham
For Balham 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. Electric opening rooflights suit rooms that overheat in summer or steam up when cooking.
We work across Greater London, including Balham, and in neighbouring towns such as Clapham and Streatham. Access, parking and how the glass reaches the roof are all checked at the survey.
Choices for your Balham project
- Double or triple glazing
- Smart-home or app control (manufacturer dependent)
- Insect screen
- Electric actuator with wall switch or remote
- Integral blind
- Clears cooking steam and summer heat at ceiling level
- Daylight and purge ventilation from one unit
Things we check at survey
- Needs a power supply at the opening — plan the cable route before ceilings close up
- Electrical connection should be made by a competent electrician to BS 7671
Consents for electric opening rooflights in Balham
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. 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.

Common questions
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.
Is it secure when open?
An opening rooflight is a vent, not an access hatch, so the gap is small. For security, close it when the house is empty — a rain sensor does not lock the unit.
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.
Is the survey in Balham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Balham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
