Electric opening rooflights for Wandsworth: the essentials
We handle electric opening rooflights across Greater London, including Wandsworth. 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.
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. Electric opening rooflights suit kitchens, bathrooms and bedrooms that need fresh air as well as light.
From Wandsworth to Battersea, Chelsea and Fulham, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Rain and wind sensor
- Double or triple glazing
- Electric actuator with wall switch or remote
- Insect screen
- Frame colour to match your doors
- Rain sensor closes the lid automatically
- Daylight and purge ventilation from one unit
Things we check at survey
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
- Opening area may count toward purge ventilation for the room
Consents for electric opening rooflights in Wandsworth
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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 Wandsworth
Can it open in a power cut?
Most electric units stay where they are during a power cut. Some manufacturers offer a manual override or battery backup — we will tell you which option the chosen model has.
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.
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.
