Storage and electric heater replacement in Cardiff
Old storage heaters in Cardiff homes are removed and recycled as part of the replacement. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.
Flats and bungalows in Cardiff that have never had gas are the usual candidates for replacing storage heaters. We cover Cardiff and the rest of South Glamorgan, including Barry and Penarth. That includes the CF10, CF11, CF14, CF15, CF23 and CF24 postcode districts.
Prices in Cardiff
Budget around £3,145–£9,595 for 3–5 rooms including VAT for storage and electric heater replacement in and around Cardiff. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. Typical Bungalow or house work (four rooms on one outdoor unit) lands around £4,545–£7,295 in this area.
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
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Cardiff can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
Cardiff 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.

We book surveys in Cardiff at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
