Electric opening rooflights in Crowthorne: what is involved?
Thinking about electric opening rooflights in Crowthorne? The short answer: hinged rooflights that open on an electric actuator for fresh air. The longer answer depends on your roof, which is why we survey before we price.
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 Crowthorne, as anywhere, electric opening rooflights are the usual choice for rooms that overheat in summer or steam up when cooking.
Crowthorne sits about 3 km from Sandhurst and 4 km from Yateley, and we cover the whole RG45 postcode district and the roads in between.
What you can choose
- Smart-home or app control (manufacturer dependent)
- Electric actuator with wall switch or remote
- Integral blind
- Rain and wind sensor
- Manual winder on smaller units
- Daylight and purge ventilation from one unit
- 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
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Do you need permission in Crowthorne?
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 Crowthorne
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.
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.
