How we approach electric opening rooflights in Dover
For Dover 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Dover, as anywhere, electric opening rooflights are the usual choice for kitchens, bathrooms and bedrooms that need fresh air as well as light.
Jobs in Dover 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.
Options we can specify in Dover
- Smart-home or app control (manufacturer dependent)
- Rain and wind sensor
- Double or triple glazing
- Frame colour to match your doors
- Insect screen
- Rain sensor closes the lid automatically
- Can be grouped with fixed units on one roof
Before you order: points to check
- Electrical connection should be made by a competent electrician to BS 7671
- Needs a power supply at the opening — plan the cable route before ceilings close up
Do you need permission in Dover?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Electric opening rooflights in Dover: questions
Can it open in a power cut?
Most electric units stay where they are during a power cut. Some manufacturers offer a manual override or battery backup — we will tell you which option the chosen model has.
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.
How do I book a survey in Dover?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Can you work alongside my builder in Dover?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
