Electric opening rooflights in Tonbridge: what is involved?
For Tonbridge homes and buildings we offer electric opening rooflights: hinged rooflights that open on an electric actuator for fresh air. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of electric opening rooflights for rooms that overheat in summer or steam up when cooking.
Jobs in Tonbridge 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.
What you can choose
- Rain and wind sensor
- Insect screen
- Smart-home or app control (manufacturer dependent)
- Frame colour to match your doors
- Electric actuator with wall switch or remote
- Can be grouped with fixed units on one roof
- Daylight and purge ventilation from one unit
What to check first
- Needs a power supply at the opening — plan the cable route before ceilings close up
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Planning and building rules for Tonbridge
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. 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.

Common questions
Is it noisy?
Actuators run for a few seconds and are about as loud as an electric blind. Once closed, an opening unit is as quiet as a fixed one.
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 Tonbridge free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
