How we approach electric opening rooflights in Lewisham
Thinking about electric opening rooflights in Lewisham? 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.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. In Lewisham, as anywhere, electric opening rooflights are the usual choice for kitchens, bathrooms and bedrooms that need fresh air as well as light.
From Lewisham to Catford, Peckham and Greenwich, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Frame colour to match your doors
- Manual winder on smaller units
- Electric actuator with wall switch or remote
- Insect screen
- Smart-home or app control (manufacturer dependent)
- Can be grouped with fixed units on one roof
- Rain sensor closes the lid automatically
What to check first
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
- Needs a power supply at the opening — plan the cable route before ceilings close up
Consents for electric opening rooflights in Lewisham
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Electric opening rooflights in Lewisham: questions
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.
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.
