Storage and electric heater replacement in Isleworth
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. Old storage heaters in Isleworth homes are removed and recycled as part of the replacement.
Flats and bungalows in Isleworth that have never had gas are the usual candidates for replacing storage heaters. Isleworth lies roughly 10 miles from central London, and we cover it as part of London. Homes in TW7 are all within our coverage.
Prices in Isleworth
Our London guide price for storage and electric heater replacement is £4,545–£13,795 for 3–5 rooms, VAT included. That is above the UK middle, mainly because labour and access cost more in London. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. For reference, the Bungalow or house option in Isleworth (four rooms on one outdoor unit) usually comes to about £6,545–£10,495.
Small flat
Two or three rooms replacing storage heaters.

Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
Isleworth is in the Boiler Upgrade Scheme area, so eligible homes replacing oil, gas, LPG or electric heating may be able to get £2,500 off an air-to-air heat pump, as long as no fossil-fuel boiler stays in use. An MCS-certified installer must claim it; we confirm eligibility, and which installer applies, before you commit.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. On a survey in Isleworth the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
