Electric opening rooflights in Leytonstone: what is involved?
Our electric opening rooflights service in Leytonstone 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of electric opening rooflights for rooms that overheat in summer or steam up when cooking.
We work across Greater London, including Leytonstone, and in neighbouring towns such as Walthamstow and Hackney. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Electric actuator with wall switch or remote
- Integral blind
- Insect screen
- Smart-home or app control (manufacturer dependent)
- Double or triple glazing
- Can be grouped with fixed units on one roof
- Electric opening — no poles or winding
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
Planning and building rules for Leytonstone
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.
Read the planning permission guide before you commit to a design.

Questions about electric opening rooflights in Leytonstone
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 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.
Can you work alongside my builder in Leytonstone?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Leytonstone?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
