Electric opening rooflight installation in Hounslow

Guide prices in Hounslow

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.

Is your address covered?

Distance is rarely the deciding factor. A roof in Isleworth, 1 mile from Hounslow, gets the same survey, the same written quote and the same fitting process as one in TW3, TW4 and TW5. What changes the price is the job itself: size of unit, roof type, access and lifting. Heston, around 1 mile out, is treated the same way.

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.

What the job includes

• Rain sensor positioned where it will get wet when rain starts
• Unit fitted, sealed and weathered like a fixed flat rooflight
• Cable route and controls set up ready for the electrician's final connection, quoted as a separate line
• Opening onto a side slope — We check where the opening part will sit if the roof is pitched or the unit faces a neighbour.
• Cable length and size — We check the cable run against the maker's limits before planning where the controls go.

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 an electric opening 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 Hounslow 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.

Getting a price from photos

For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as TW3.
