Dome rooflight replacement in Finchley

Guide prices

Guide ranges for supply & fit, per dome; building control notice fee extra on homes in England and Wales. 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 Finchley

Finchley and the districts around it, N3, N12 and N2, all sit inside our working area. So does the ground between Finchley and Golders Green (2 miles), and on towards Friern Barnet (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.

Already bought your unit?

Your unit or ours, the fitting standard is the same. For supply and fit we choose a dome rooflight to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

What we do on the day

• Kerb checked for rot, size and height before the new unit goes on
• Adaptor or packing fitted where the old kerb needs it
• New multi-skin dome or glass unit fixed and sealed
• Is the kerb sound? — We check each kerb for rot and movement before quoting a dome swap.
• Fragile dome safety — We treat old domes as fragile at all times.

Fitting your dome rooflight, step by step

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a dome rooflight: a few hours per dome, weather permitting.

Planning, building control and Finchley

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.

What to send for a quick quote

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in N3, and we can price it.
