New rooflight in an existing roof in Swanley

Guide prices

Guide ranges for supply & fit, including structure and making good; building control or warrant fees extra. 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 BR8 and neighbouring districts

Covering Swanley means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in BR8, DA4 and DA2, and are happy to quote further out in Bexley and Orpington. 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.

Your rooflights or ours

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a new 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

• Rooflight fitted, sealed and checked for even clearance on every side
• Joists or rafters trimmed with new timbers to carry the load around
• Insulated upstand built square, level and to the maker's height
• Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.
• Which way the joists run — We check the direction and size of the joists before fixing the rooflight's position.

What happens on the day

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 new rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Do you need permission in Swanley?

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.

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 BR8, and we can price it.
