What do electric opening rooflights in Barnes involve?
We handle electric opening rooflights across Greater London, including Barnes. 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Barnes, as anywhere, electric opening rooflights are the usual choice for rooms that overheat in summer or steam up when cooking.
Barnes sits about 2 km from Chiswick and 3 km from Putney, and we cover the whole SW13 postcode district and the roads in between.
Choices for your Barnes project
- Manual winder on smaller units
- Integral blind
- Smart-home or app control (manufacturer dependent)
- Double or triple glazing
- Rain and wind sensor
- 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
- Electrical connection should be made by a competent electrician to BS 7671
Planning and building rules for Barnes
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.

Questions about electric opening rooflights in Barnes
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.
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.
Is the survey in Barnes free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Barnes?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
