Electric opening rooflight installation in Chiswick

What the job costs in Chiswick

Guide ranges for supply & fit; the electrician's final connection is quoted separately. 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.

Areas around Chiswick we cover

Covering Chiswick means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in W4, W3 and W6, and are happy to quote further out in Acton and Barnes. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.

Buying your own, or letting us supply

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put an electric opening rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

On the day, we cover

• Cable route and controls set up ready for the electrician's final connection, quoted as a separate line
• Opening and closing tested, with controls explained at handover
• Rain sensor positioned where it will get wet when rain starts
• Cable length and size — We check the cable run against the maker's limits before planning where the controls go.
• Who makes the final connection — We confirm who will connect the rooflight to the mains before booking.

What happens on the day

Where a job takes one day, plus the electrician's connection, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then an electric opening rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Planning, building control and Chiswick

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Before you get in touch

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 W4, and we can price it.
