How we approach electric opening rooflights in Trowbridge
Our electric opening rooflights service in Trowbridge 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.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Think of electric opening rooflights for rooms that overheat in summer or steam up when cooking.

Consents for electric opening rooflights in Trowbridge
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

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