Conservation rooflight installation in Dorset

Most people looking for conservation rooflight installation in Dorset want three answers: can you do it, what will it cost, and when. Yes, anywhere in Dorset. Cost starts from a guide of £1,145 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 conservation rooflight, are usually priced from photos.

Towns we list in Dorset

Builders and roofers working in Dorset 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.

Included in the work

  • Position checked against any consent drawings or council conditions
  • Flashings in lead or a matching kit, dressed to the covering
  • Slates or tiles lifted carefully and kept for reuse where possible
  • Conservation area rules by nation — We check the permitted development position for your nation before the rooflight is ordered.
  • Listed building consent — We confirm listed building consent is in place before fitting any rooflight on a listed building.

Rules that apply in England

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Common questions in Dorset

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 Dorset?

Yes. Fitters travel to addresses in Dorset and the surrounding districts, including BH, DT and SP 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.

Will my new conservation rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
