How we approach electric opening rooflights in St Austell
Thinking about electric opening rooflights in St Austell? 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 West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Typical uses for electric opening rooflights include rooms that overheat in summer or steam up when cooking.
Neighbouring towns include Bodmin (15 km) and Truro (22 km). We offer a survey date when we reply to your enquiry.

Planning, building control and St Austell
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about electric opening rooflights in St Austell
Can I control it from my phone?
Some ranges link to smart-home hubs or their own app. If that matters, say so at survey and we will specify a compatible model.
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 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.
Can you work alongside my builder in St Austell?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in St Austell free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
