Electric opening rooflights in Melksham: what is involved?
For Melksham homes and buildings we offer electric opening rooflights: hinged rooflights that open on an electric actuator for fresh air. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Electric opening rooflights suit kitchens, bathrooms and bedrooms that need fresh air as well as light.
Neighbouring towns include Trowbridge (8 km) and Chippenham (10 km). We offer a survey date when we reply to your enquiry.
Specification options
- Integral blind
- Insect screen
- Double or triple glazing
- Electric actuator with wall switch or remote
- Frame colour to match your doors
- Can be grouped with fixed units on one roof
- Clears cooking steam and summer heat at ceiling level
What to check first
- Needs a power supply at the opening — plan the cable route before ceilings close up
- Opening area may count toward purge ventilation for the room
Planning, building control and Melksham
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

Questions about electric opening rooflights in Melksham
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.
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.
Is the survey in Melksham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Melksham?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
