How we approach skylight installation in Witney
Our skylight installation service in Witney covers survey, supply and fit — new openings, extensions and fit-only work. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Witney, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
Witney is around 16 km from Oxford, and we survey and fit throughout that part of Oxfordshire, including the OX28 district.

Do you need permission in Witney?
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Skylight installation in Witney: questions
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 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 offer skylight installation in Witney?
Yes. We carry out skylight installation in Witney and across Oxfordshire. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Witney?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
