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.

Towns we list in Greater London

We work right across England, and Greater London is covered on the same footing as everywhere else. There is no showroom or depot to visit. The survey happens at your property or, for fit-only jobs, from your photos. If your address is remote or reached by ferry, tell us early and we will confirm what arrangement is needed before quoting.

What's included

Glass bedded on the specified tape or sealant and fixed through the concealed frame
Lifting gear arranged for heavy single panes where two people cannot safely carry
Kerb squared across the diagonals before the glass is ordered or fitted
Laminated inner pane — We confirm the inner pane is laminated or otherwise suited to being overhead.
Tolerance on the upstand — We build frameless kerbs to the maker's tolerance rather than to normal carpentry accuracy.

Rules that apply in England

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.

Common questions in Greater London

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

What if my roof opening is the wrong size for the frameless rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

Do you cover Greater London?

Yes. Fitters travel to addresses in Greater London and the surrounding districts, including BR, CR, DA, E, EC, EN, HA, IG, KT, N, NW, RM, SE, SM, SW, TN, TW, UB, W and WC postcodes. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
