Storage and electric heater replacement in Chiswick
Flats and bungalows in Chiswick that have never had gas are the usual candidates for replacing storage heaters. The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights.
For Chiswick landlords, swapping storage heaters for a heat pump is one of the more effective EPC improvements. Chiswick sits around 6 miles from central London, inside our London area. Postcode districts we cover here include W4.
Prices in Chiswick
Storage and electric heater replacement in Chiswick typically comes in at £4,545–£13,795 for 3–5 rooms including VAT, based on London rates. Prices here sit above the national middle, reflecting London labour rates and parking and access costs. What moves a quote in Chiswick up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed. On our London figures, the Bungalow or house option (four rooms on one outdoor unit) is about £6,545–£10,495.

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
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
Chiswick 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.

We book surveys in Chiswick at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Chiswick cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
