Roof lantern installation in Bayswater

Our guide price for roof lantern installation starts from £3,095, and the real figure for your roof in Bayswater depends on a handful of things: the size and type of roof lantern, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of Greater London.

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.

Covering W2 and neighbouring districts

Fitters travel to the job, so the address is what counts. In Bayswater that means postcode districts W2, W8 and W11, and the same teams can just as easily take on work in Kensington, about 1 mile away, or Notting Hill at roughly 1 mile. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Buying your own, or letting us supply

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a roof lantern, 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 the job includes

  • Internal trims fitted to the ring beam or upstand
  • Caps, end closures and ridge trims fitted and sealed
  • Glass cleaned and packaging cleared from the roof
  • Level, not to a fall — We set or check the kerb level unless your lantern's maker says otherwise.
  • Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.

What happens on the day

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 roof lantern 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.

Planning, building control and Bayswater

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

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 W2, and we can price it.

Common questions in Bayswater

What upstand height and roof pitch does roof lantern fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

How long does fitting take?

Fitting a roof lantern into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

Got a unit waiting to go in, or need one sourced? Either way, start with your Bayswater address and a couple of photos.
