Towns we list in Wiltshire
Builders and roofers working in Wiltshire can use us for the rooflight element of a job, wherever the site is in England. Homeowners can book us directly. In both cases the fitters come to the address, the work follows the maker's instructions, and a written quote fixes the price first. Fitting is carried out by vetted teams under S&K's direction.

What the job includes
- Dome fixed and sealed on top of the flashing
- Dust cleared from the room below and the loft

- Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
- Tube size — We match the tube size to the room and the roof.
Rules that apply in England
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
Common questions in Wiltshire
What if my roof opening is the wrong size for the sun tunnel?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
How long does fitting take?
Fitting a sun tunnel into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
