New rooflight in an existing roof in Soho

Soho 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.

Is your address covered?

Distance is rarely the deciding factor. A roof in Pimlico, 2 miles from Soho, gets the same survey, the same written quote and the same fitting process as one in W1F, W1B and W1D. What changes the price is the job itself: size of unit, roof type, access and lifting. Camden Town, around 2 miles out, is treated the same way.

What we check on a supplied unit

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

What we do on the day

• Joists or rafters trimmed with new timbers to carry the load around
• Opening marked out, covering stripped back and the deck cut cleanly
• Rooflight fitted, sealed and checked for even clearance on every side
• Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.
• Planning for your roof — We check whether the new rooflight falls within permitted development for your house and nation.

Fitting your rooflight, step by step

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a new rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Regulations for Soho properties

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.

Before you get in touch

A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, W1F or a neighbouring district.
