How we approach electric opening rooflights in Hampstead
Our electric opening rooflights service in Hampstead covers hinged rooflights that open on an electric actuator for fresh air. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Hampstead, as anywhere, electric opening rooflights are the usual choice for rooms that overheat in summer or steam up when cooking.
We work across Greater London, including Hampstead, and in neighbouring towns such as Kilburn and Highgate. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Hampstead
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about electric opening rooflights in Hampstead
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.
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.
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.
