Storage and electric heater replacement in Grays
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. Flats and bungalows in Grays that have never had gas are the usual candidates for replacing storage heaters.
Old storage heaters in Grays homes are removed and recycled as part of the replacement. We cover Grays as part of Essex, roughly 17 miles from Southend-on-Sea. Postcode districts we cover here include RM17.
Prices in Grays
For Grays, expect roughly £3,845 to £11,695 for 3–5 rooms, VAT included, adjusted for typical East of England rates. That is above the UK middle, mainly because labour and access cost more in the East of England. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Bungalow or house option in Grays (four rooms on one outdoor unit) usually comes to about £5,545–£8,895.
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.
If your home in Grays 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
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. We book surveys in Grays at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
