Electric opening rooflights for Guildford: the essentials
We handle electric opening rooflights across Surrey, including Guildford. In short: hinged rooflights that open on an electric actuator for fresh air. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of electric opening rooflights for kitchens, bathrooms and bedrooms that need fresh air as well as light.
From Guildford to Godalming, Woking and Aldershot, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Integral blind
- Manual winder on smaller units
- Rain and wind sensor
- Smart-home or app control (manufacturer dependent)
- Insect screen
- Electric opening — no poles or winding
- Can be grouped with fixed units on one roof
Before you order: points to check
- Opening area may count toward purge ventilation for the room
- Electrical connection should be made by a competent electrician to BS 7671
Consents for electric opening rooflights in Guildford
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. 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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

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