Roof lantern installation in Highbury

Guide prices

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.

Fitting across Highbury and nearby

Jobs across N5, N7 and N1 are part of our normal cover for Highbury. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Islington and Holloway are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Already bought your unit?

There are two ways to do this. Supply and fit means we source a roof lantern that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What we do on the day

• Roof membrane checked where it meets the lantern frame
• Glass lifted and laid into the frame by hand or with gear
• Frame assembled on the kerb in the maker's set order
• Level, not to a fall — We set or check the kerb level unless your lantern's maker says otherwise.
• Following the build order — We assemble lanterns in exactly the sequence the instructions give.

Fitting your roof lantern, step by step

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

Do you need permission in Highbury?

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.

Details that speed up your quote

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 N5 and we will come back with a quote or a survey date.
