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.
Areas around Northolt we cover
Distance is rarely the deciding factor. A roof in Greenford, 1 mile from Northolt, gets the same survey, the same written quote and the same fitting process as one in UB5, UB6 and HA2. What changes the price is the job itself: size of unit, roof type, access and lifting. Harrow, around 3 miles out, is treated the same way.
Buying your own, or letting us supply
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.
What the job includes
- Tube insulated where it passes through a cold loft
- Route through the loft checked for joists, cables and pipes
- Ceiling opening cut neatly and the diffuser fitted
- Rigid or flexible tube — We check whether a rigid tube will fit the route before falling back on a flexible one.
- Flat or pitched roof kit — We confirm the roof type and covering before ordering the kit.
What happens on the day
Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a sun tunnel level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes half a day to a day.
Planning and building rules in England
England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.
Getting a price from photos
A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, UB5 or a neighbouring district.
Common questions in Northolt
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.
Do you cover Northolt?
Yes. Fitters travel to addresses in Northolt and the surrounding districts, including UB5. 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.
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.
