Storage and electric heater replacement in Harrow
Flats and bungalows in Harrow that have never had gas are the usual candidates for replacing storage heaters. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
Old storage heaters in Harrow homes are removed and recycled as part of the replacement. Harrow lies roughly 10 miles from central London, and we cover it as part of London. That includes the HA2 postcode district.
Prices in Harrow
Budget around £4,545–£13,795 for 3–5 rooms including VAT for storage and electric heater replacement in and around Harrow. London is one of the dearer parts of the UK for trades, which shows in the range. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Bungalow or house option (four rooms on one outdoor unit) would typically be £6,545–£10,495 here.
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
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.
Harrow 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
A survey in Harrow usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes. On a survey in Harrow 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.
