Electric opening rooflights for Croydon: the essentials
Our electric opening rooflights service in Croydon 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. Typical uses for electric opening rooflights include rooms that overheat in summer or steam up when cooking.
From Croydon to South Croydon, Wallington and Carshalton, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Rain and wind sensor
- Manual winder on smaller units
- Double or triple glazing

What to check first
- Needs a power supply at the opening — plan the cable route before ceilings close up
- Opening area may count toward purge ventilation for the room
Planning and building rules for Croydon
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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.
Do I need to be at home for the survey in Croydon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Croydon?
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.
