Electric opening rooflights for Purley: the essentials
We handle electric opening rooflights across Greater London, including Purley. In short: hinged rooflights that open on an electric actuator for fresh air. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Typical uses for electric opening rooflights include rooms that overheat in summer or steam up when cooking.
Purley sits about 3 km from Coulsdon and 3 km from South Croydon, and we cover the whole CR8 postcode district and the roads in between.
What you can choose
- Integral blind
- Electric actuator with wall switch or remote
- Double or triple glazing
- Rain and wind sensor
- Manual winder on smaller units
- Can be grouped with fixed units on one roof
- Clears cooking steam and summer heat at ceiling level
Before you order: points to check
- Opening area may count toward purge ventilation for the room
- Electrical connection should be made by a competent electrician to BS 7671
Planning and building rules for Purley
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Electric opening rooflights in Purley: questions
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.
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.
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 the survey in Purley 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 Purley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
