Commercial rooflight installation in Lancing

Our guide price for commercial rooflight installation starts from £1,095, and the real figure for your roof in Lancing depends on a handful of things: the size and type of commercial rooflight, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of West Sussex.

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.

Where our fitters travel

Lancing and the districts around it, BN15, BN14 and BN43, all sit inside our working area. So does the ground between Lancing and Shoreham-by-Sea (2 miles), and on towards Worthing (2 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

On the day, we cover

  • Unit schedule and handover notes for the building's records
  • Old units removed, with waste taken off site
  • Kerbs checked and packed, adapted or rebuilt where needed
  • 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.

From arrival to clean-up

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.

Do you need permission in Lancing?

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.

Getting a price from photos

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around BN15 and we will come back with a quote or a survey date.

Common questions in Lancing

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.

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.

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.
