Areas around Bath we cover
Covering Bath means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in BA1, BA2 and BS31, and are happy to quote further out in Keynsham and Trowbridge. 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.
Fit-only or supply and fit
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a sun tunnel on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
Included in the work
- Dome fixed and sealed on top of the flashing
- Roof opening cut and the flashing fitted to tiles, slates or a flat-roof kit
- Route through the loft checked for joists, cables and pipes
- Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.
- Condensation in cold lofts — We insulate the tube where it passes through a cold loft.
Fitting your sun tunnel, step by step
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a sun tunnel, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Do you need permission in Bath?
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.
Details that speed up your quote
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 BA1.
Common questions in Bath
Will my new sun tunnel leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
Do you cover Bath?
Yes. Fitters travel to addresses in Bath and the surrounding districts, including BA1. 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.
Does a rooflight need building regulations approval?
A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.
