Skylight installation in Thetford: what is involved?
Thinking about skylight installation in Thetford? 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 homes in the East have low-pitched roofs on later extensions, which are better served by flat rooflights than pitched roof windows. In Thetford, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
Thetford sits about 19 km from Bury St Edmunds and 25 km from Diss, and we cover the whole IP24 postcode district and the roads in between.

Planning and building rules for Thetford
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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. 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.
Read the planning permission guide before you commit to a design.

Questions about skylight installation in Thetford
Is the survey free?
Yes, for new installations. Repair visits are charged.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
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.
Can you work alongside my builder in Thetford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Thetford?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
