Dome rooflight replacement in Keynsham

Guide prices in Keynsham

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.

Covering BS31 and neighbouring districts

Distance is rarely the deciding factor. A roof in Kingswood, 3 miles from Keynsham, gets the same survey, the same written quote and the same fitting process as one in BS31, BS39 and BA1. What changes the price is the job itself: size of unit, roof type, access and lifting. Mangotsfield, around 5 miles out, is treated the same way.

Already bought your unit?

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a dome rooflight, 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 builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

What we do on the day

• Adaptor or packing fitted where the old kerb needs it
• New multi-skin dome or glass unit fixed and sealed
• Membrane checked where it meets the kerb, with small repairs made
• Upgrading to glass — We check whether the kerb suits a glass unit before recommending one.
• Is the kerb sound? — We check each kerb for rot and movement before quoting a dome swap.

A typical installation 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 dome rooflight 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 a few hours per dome.

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.

Help us quote accurately

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 BS31 and we will come back with a quote or a survey date.
