Skylight installation in Henley-on-Thames: what is involved?
Thinking about skylight installation in Henley-on-Thames? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of skylight installation for builders' projects and retrofits into finished roofs.
Henley-on-Thames sits about 10 km from Reading and 12 km from Earley, and we cover the whole RG9 postcode district and the roads in between.

Do you need permission in Henley-on-Thames?
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
Is the survey free?
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 Henley-on-Thames?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Henley-on-Thames?
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.
