Electric opening rooflights in Feltham: what is involved?
For Feltham 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Electric opening rooflights suit rooms that overheat in summer or steam up when cooking.
From Feltham to Ashford, Surrey, Hounslow and Sunbury-on-Thames, the same survey-first process applies: measure, specify, fix the price, then fit.
Choices for your Feltham project
- Electric actuator with wall switch or remote
- Double or triple glazing
- Smart-home or app control (manufacturer dependent)
- Frame colour to match your doors
- Rain and wind sensor
- Rain sensor closes the lid automatically
- Same slim look as a fixed unit when closed
What to check first
- Opening area may count toward purge ventilation for the room
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Planning and building rules for Feltham
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. 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.
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. 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.

Electric opening rooflights in Feltham: questions
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.
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.
Do I need to be at home for the survey in Feltham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Feltham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
