Rooflight replacement in Didcot

Guide prices

Guide ranges for supply & fit; building control notice fee extra 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 Didcot

Looking at a property near Didcot but not quite in it? We work across OX11, OX14 and OX10 and outwards to Abingdon, Cowley and Oxford. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Didcot.

Fit-only or supply and fit

Your unit or ours, the fitting standard is the same. For supply and fit we choose a replacement 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.

On the day, we cover

• Old rooflight or dome unscrewed, lifted out and taken away for disposal
• Building notice given to the council in England and Wales, with its fee on the quote
• Packers, an adaptor or a new insulated upstand where the old kerb falls short
• Inside finishes — We check the condition of the plaster and trim around the opening from inside.
• Dome to glass upgrades — We check that the opening and kerb suit a flat glass unit before quoting a dome-to-glass swap.

A typical installation day

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A replacement rooflight goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one day.

Planning, building control and Didcot

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

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around OX11. That is enough for a first price.
