What do electric opening rooflights in Catford involve?
Thinking about electric opening rooflights in Catford? The short answer: hinged rooflights that open on an electric actuator for fresh air. The longer answer depends on your roof, which is why we survey before we 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. Typical uses for electric opening rooflights include rooms that overheat in summer or steam up when cooking.
We work across Greater London, including Catford, and in neighbouring towns such as Lewisham and Blackheath. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Smart-home or app control (manufacturer dependent)
- Electric actuator with wall switch or remote
- Double or triple glazing
- Insect screen
- Rain and wind sensor
- Can be grouped with fixed units on one roof
- Daylight and purge ventilation from one unit
Before you order: points to check
- 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
Planning and building rules for Catford
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Electric opening rooflights in Catford: questions
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.
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.
How do I book a survey in Catford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Catford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
