Storage and electric heater replacement in Horsham
Old storage heaters in Horsham homes are removed and recycled as part of the replacement. Hot spells reach the South East early, which makes spring the easiest time to arrange an installation.
Flats and bungalows in Horsham that have never had gas are the usual candidates for replacing storage heaters. Horsham sits around 7 miles from Crawley, inside our West Sussex area. Coverage includes RH12.
Prices in Horsham
Our South East England guide price for storage and electric heater replacement is £4,195–£12,745 for 3–5 rooms, VAT included. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. What moves a quote in Horsham up or down is mostly pipe length, how high the outdoor unit goes, and whether a new electrical circuit is needed.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
If your home in Horsham is replacing fossil fuel or electric heating, and no gas, oil or LPG boiler stays in use, an MCS-certified air-to-air heat pump may qualify for the £2,500 Boiler Upgrade Scheme grant, which the MCS-certified installer claims and deducts from the price.
The survey
A survey in Horsham 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
