Electric opening rooflights for Falmouth: the essentials
We handle electric opening rooflights across Cornwall, including Falmouth. 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. In Falmouth, as anywhere, electric opening rooflights are the usual choice for rooms that overheat in summer or steam up when cooking.
Falmouth sits about 12 km from Truro and 14 km from Redruth, and we cover the whole TR11 postcode district and the roads in between.
Specification options
- Frame colour to match your doors
- Insect screen
- Integral blind
- Manual winder on smaller units
- Rain and wind sensor
- Clears cooking steam and summer heat at ceiling level
- Can be grouped with fixed units on one roof
What to check first
- Opening area may count toward purge ventilation for the room
- Needs a power supply at the opening — plan the cable route before ceilings close up
Planning and building rules for Falmouth
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

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