New rooflight in an existing roof in Wallington

What the job costs in Wallington

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?

Fitters travel to the job, so the address is what counts. In Wallington that means postcode districts SM6, SM5 and SM1, and the same teams can just as easily take on work in Carshalton, about 1 mile away, or Sutton at roughly 2 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.

Already bought your 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.

Included in the work

• Plasterboard reveals formed inside and left ready for skim or decoration
• Roof membrane, felt or tiles made good and dressed up the upstand
• Joists or rafters trimmed with new timbers to carry the load around
• Upstand energy performance — We build the upstand to meet the energy limit for site-built upstands, not just to hold the rooflight up.
• Planning for your roof — We check whether the new rooflight falls within permitted development for your house and nation.

From arrival to clean-up

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a new rooflight: two to three days, weather permitting.

Planning and building rules 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.

Before you get in touch

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around SM6. That is enough for a first price.
