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.
Coverage in and around Wellingborough
Wellingborough and the districts around it, NN8, NN29 and NN10, all sit inside our working area. So does the ground between Wellingborough and Rushden (4 miles), and on towards Kettering (7 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.
What the job includes
- New units fitted, sealed and weathered into the roof covering
- Old units removed, with waste taken off site
- Kerbs checked and packed, adapted or rebuilt where needed
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
- Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.
A typical installation day
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.
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 NN8 and we will come back with a quote or a survey date.
Common questions in Wellingborough
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
What upstand height and roof pitch does commercial rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
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.
