Storage and electric heater replacement in Chelmsford
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. Old storage heaters in Chelmsford homes are removed and recycled as part of the replacement.
Flats and bungalows in Chelmsford that have never had gas are the usual candidates for replacing storage heaters. Chelmsford is about 17 miles from Southend-on-Sea and falls within our Essex coverage. Postcode districts we cover here include CM1.

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 Chelmsford 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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. 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.
