Sun tunnel installation in Dyfed

Most people looking for sun tunnel installation in Dyfed want three answers: can you do it, what will it cost, and when. Yes, anywhere in Dyfed. Cost starts from a guide of £595 and is fixed in a written quote once we know the roof. Timing depends on fitter availability and the weather, so you get offered dates rather than promises. Fit-only jobs, where you already own a sun tunnel, are usually priced from photos.

Towns we list in Dyfed

Fitting across Dyfed means planning routes, access and lifting as well as the roof itself. Narrow lanes, shared driveways and town-centre parking restrictions all affect how a large unit is delivered and raised to roof level. We ask about these early so the quote reflects them. That approach is the same everywhere we work in Wales, from single domestic jobs to multi-unit commercial sites.

What we do on the day

  • Route through the loft checked for joists, cables and pipes
  • Dust cleared from the room below and the loft
  • Dome fixed and sealed on top of the flashing
  • Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.
  • Flat or pitched roof kit — We confirm the roof type and covering before ordering the kit.

Rules that apply in Wales

Welsh rules differ from England's in one important way: rooflights lose permitted development rights in conservation areas, National Parks, AONBs and World Heritage Sites. Elsewhere on a house, a rooflight that projects no more than 150 mm and stays below the highest part of the roof is usually fine. Building regulations still apply to new openings, replacements we fit go through a building notice because we are not scheme-registered, and the energy limit for rooflights is 2.2 W/m²K. A new Welsh Approved Document L takes effect on 4 March 2027.

Common questions in Dyfed

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Do you cover Dyfed?

Yes. Fitters travel to addresses in Dyfed and the surrounding districts, including SA and SY postcodes. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
