Guide ranges for supply & fit. 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.
Covering WF12 and neighbouring districts
Covering Dewsbury means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in WF12, WF13 and WF17, and are happy to quote further out in Batley and Ossett. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
Buying your own, or letting us supply
A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a sun tunnel, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the opening size and the flashing kit it expects. If everything lines up, we fit it. If not, we explain what needs changing first.
What we do on the day
- Tube insulated where it passes through a cold loft
- Dome fixed and sealed on top of the flashing
- Route through the loft checked for joists, cables and pipes
- Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
- Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.
Fitting your sun tunnel, 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 sun tunnel 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
Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.
Getting a price from photos
For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as WF12.
Common questions in Dewsbury
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.
How long does fitting take?
Fitting a sun tunnel into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
What is included in the price?
The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
Got a unit waiting to go in, or need one sourced? Either way, start with your Dewsbury address and a couple of photos.
