How we approach electric opening rooflights in Ely
Thinking about electric opening rooflights in Ely? 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 homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Ely, as anywhere, electric opening rooflights are the usual choice for kitchens, bathrooms and bedrooms that need fresh air as well as light.
Ely sits about 20 km from Newmarket and 21 km from March, and we cover the whole CB7 postcode district and the roads in between.

Consents for electric opening rooflights in Ely
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. 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.

Electric opening rooflights in Ely: questions
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 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.
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.
Can you work alongside my builder in Ely?
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 Ely?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
