Electric opening rooflights for Chatham: the essentials
Thinking about electric opening rooflights in Chatham? 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Electric opening rooflights suit rooms that overheat in summer or steam up when cooking.
Jobs in Chatham are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Chatham
- Frame colour to match your doors
- Double or triple glazing
- Integral blind
- Electric actuator with wall switch or remote
- Rain and wind sensor
- Same slim look as a fixed unit when closed
- Clears cooking steam and summer heat at ceiling level
What to check first
- Lid opening height is limited by the actuator stroke, typically a few hundred millimetres
- Electrical connection should be made by a competent electrician to BS 7671
Planning and building rules for Chatham
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about electric opening rooflights in Chatham
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.
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 you work alongside my builder in Chatham?
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 Chatham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
