Storage and electric heater replacement in Harpenden
Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure. Flats and bungalows in Harpenden that have never had gas are the usual candidates for replacing storage heaters.
Old storage heaters in Harpenden homes are removed and recycled as part of the replacement. Harpenden is about 11 miles from Watford and falls within our Hertfordshire coverage. We cover AL5 and the streets around them.
Prices in Harpenden
Storage and electric heater replacement in Harpenden typically comes in at £3,845–£11,695 for 3–5 rooms including VAT, based on East of England rates. That is above the UK middle, mainly because labour and access cost more in the East of England. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. On our East of England figures, the Bungalow or house option (four rooms on one outdoor unit) is about £5,545–£8,895.
Small flat
Two or three rooms replacing storage heaters.
Bungalow or house
Four rooms on one outdoor unit.
Larger home
Five or more rooms or two outdoor units.
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.
Harpenden 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 Harpenden 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. We book surveys in Harpenden at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
