What does skylight installation in Thatcham involve?
Thinking about skylight installation in Thatcham? 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.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Thatcham is around 21 km from Reading, and we survey and fit throughout that part of Berkshire, including the RG18 district.

Planning and building rules for Thatcham
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight installation in Thatcham
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 long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Will I need planning permission in Thatcham?
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.
Can you work alongside my builder in Thatcham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
