Programme of works
Phased replacement across a building, priced from a survey
Guide ranges for supply & fit, per unit; site set-up priced separately. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Areas around Nelson we cover
Distance is rarely the deciding factor. A roof in Colne, 2 miles from Nelson, gets the same survey, the same written quote and the same fitting process as one in BB9, BB8 and BB10. What changes the price is the job itself: size of unit, roof type, access and lifting. Burnley, around 3 miles out, is treated the same way.
What we do on the day
- Unit schedule and handover notes for the building's records
- Old units removed, with waste taken off site
- New units fitted, sealed and weathered into the roof covering
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
Fitting your commercial rooflight, step by step
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a commercial rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Planning and building rules in England
For non-domestic roofs in England, expect building control involvement for new openings, energy limits of 2.2 W/m²K for rooflights, and fire checks where rooflights sit near a boundary or above an escape route. Smoke ventilation rooflights must be certified products, with controls commissioned by a specialist. We set out what applies to your building on the quote.
Help us quote accurately
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, BB9 or nearby, confirms travel.
Common questions in Nelson
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.
Does commercial rooflight work need building control?
Usually. New openings, structural changes and smoke vents go through building control, and on buildings covered by fire safety law that means a full plans application rather than a building notice. We are not registered with a competent person scheme, so replacements we fit are notified to building control. We confirm the route and show any fee on the quote.
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
