What do electric opening rooflights in Bexley involve?
Our electric opening rooflights service in Bexley 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. Think of electric opening rooflights for kitchens, bathrooms and bedrooms that need fresh air as well as light.
Jobs in Bexley are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Double or triple glazing
- Electric actuator with wall switch or remote
- Frame colour to match your doors

- Smart-home or app control (manufacturer dependent)
- Rain sensor closes the lid automatically
- Can be grouped with fixed units on one roof
Things we check at survey
- Electrical connection should be made by a competent electrician to BS 7671
- Opening area may count toward purge ventilation for the room
Do you need permission in Bexley?
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.
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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Will I need planning permission in Bexley?
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.
Do I need to be at home for the survey in Bexley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
