Skylight installation in Sudbury: what is involved?
Thinking about skylight installation in Sudbury? 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.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Skylight installation suits builders' projects and retrofits into finished roofs.
Sudbury is around 29 km from Ipswich, and we survey and fit throughout that part of Suffolk, including the CO10 district.

Consents for skylight installation in Sudbury
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight installation in Sudbury: questions
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
How do I book a survey in Sudbury?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Will I need planning permission in Sudbury?
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.
