Towns we list in Lancashire

From the larger towns to the smaller places in between, we take on rooflight fitting across Lancashire. The process is the same for a terrace, a farmhouse extension or an industrial unit: details first, written quote second, fitting day third. Remote and island addresses in England, where they arise, are covered by arrangement, and we tell you that before quoting.

Included in the work

Perimeter joints sealed and the waterproofing lapped as the maker shows
Drainage around the unit checked so water does not lie on the glass
Lifting plan for the unit, including people or gear for the day
Units tested to old standards — We check which standard the walk-on unit has been tested to.
Structural calculations — We need structural calculations for the glass and its support before a walk-on job goes ahead.

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 Lancashire

Do I need planning permission for a rooflight in Lancashire?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

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 Lancashire?

Yes. Fitters travel to addresses in Lancashire and the surrounding districts, including BB, FY, L, LA, OL, PR and WN 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.
