How we approach electric opening rooflights in Sevenoaks
Electric opening rooflights in Sevenoaks means hinged rooflights that open on an electric actuator for fresh air. We cover the TN13 district and the rest of Kent, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of electric opening rooflights for rooms that overheat in summer or steam up when cooking.
Sevenoaks is around 23 km from Maidstone, and we survey and fit throughout that part of Kent, including the TN13 district.
What you can choose
- Manual winder on smaller units
- Electric actuator with wall switch or remote
- Smart-home or app control (manufacturer dependent)

- Same slim look as a fixed unit when closed
What to check first
- 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, building control and Sevenoaks
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.
See our building regulations guide for U-values, glazing limits and self-certification.

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.
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 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.
