What does skylight installation in Exeter involve?
Thinking about skylight installation in Exeter? The short answer: survey, supply and fit — new openings, extensions and fit-only work. 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 skylight installation include builders' projects and retrofits into finished roofs.
Jobs in Exeter are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Exeter
- New openings with joist trimming
- Upstands and flashings
- Supply and fit
- Electrics coordination
- Internal plaster reveal

Before you order: points to check
- Work at height is planned with suitable access
- Structural changes may need an engineer's check
Do you need permission in Exeter?
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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.

For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.

Yes, for new installations. Repair visits are charged.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do I need to be at home for the survey in Exeter?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
