Electric opening rooflights for Greenwich: the essentials
Electric opening rooflights in Greenwich means hinged rooflights that open on an electric actuator for fresh air. We cover the SE10 district and the rest of Greater London, with a survey before any price is fixed.
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. Electric opening rooflights suit kitchens, bathrooms and bedrooms that need fresh air as well as light.
From Greenwich to Blackheath, Lewisham and Catford, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Integral blind
- Electric actuator with wall switch or remote
- Double or triple glazing
- Smart-home or app control (manufacturer dependent)
- Frame colour to match your doors
- Daylight and purge ventilation from one unit
- Clears cooking steam and summer heat at ceiling level
Things we check at survey
- Opening area may count toward purge ventilation for the room
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
Do you need permission in Greenwich?
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.
What do electric opening rooflights cost in Greenwich?
These are typical supply-and-fit ranges. For an address in Greenwich, scaffold, a hoist for heavy glass, or a new structural opening can move the figure, which is why we survey first.

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