How we approach electric opening rooflights in Streatham
Our electric opening rooflights service in Streatham covers hinged rooflights that open on an electric actuator for fresh air. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. In Streatham, as anywhere, electric opening rooflights are the usual choice for rooms that overheat in summer or steam up when cooking.
We work across Greater London, including Streatham, and in neighbouring towns such as Balham and Clapham. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Double or triple glazing
- Smart-home or app control (manufacturer dependent)
- Electric actuator with wall switch or remote
- Rain and wind sensor
- Manual winder on smaller units
- Same slim look as a fixed unit when closed
- Can be grouped with fixed units on one roof
What to check first
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
- Needs a power supply at the opening — plan the cable route before ceilings close up
Planning and building rules for Streatham
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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 Streatham
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.
What happens if it rains while it is open?
With a rain sensor fitted, the actuator closes the lid automatically when the sensor detects water. Without one, the lid stays where you left it, which is why we recommend the sensor on any unit over a kitchen or bedroom.
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.
Do I need to be at home for the survey in Streatham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Streatham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
