How much is a Mitsubishi Electric Ecodan air source heat pump installed in the UK (2026)?
A Mitsubishi Electric Ecodan air source heat pump costs £9,000 - £14,000 fully installed in the UK before any support (indicative, June 2026, with 0% VAT already applied). After the £7,500 Boiler Upgrade Scheme grant in England and Wales, that is illustratively £1,500 - £6,500 out of pocket. The smallest model (Ecodan R290 8.5kW, 8.5kW heat output) starts around £9,000 pre-grant; the largest (Ecodan R290 11.2kW, 11.2kW) tops out around £14,000. Combi-to-cylinder conversions and radiator upgrades add to these figures, so always confirm with a written quote.
Is a Mitsubishi Electric Ecodan heat pump eligible for the £7,500 grant?
Yes. Every air-to-water unit on this page qualifies for the Boiler Upgrade Scheme in England and Wales when it is fitted by an MCS-certified installer, who applies for the grant on your behalf so it comes straight off the quote. From 21 July 2026 homes heated by oil or LPG can claim £9,000 instead of £7,500. Scotland uses the Home Energy Scotland grant and loan instead; Northern Ireland currently has no equivalent scheme. Grant details accurate as at June 2026.
Is Mitsubishi Electric Ecodan a good air source heat pump brand?
The best-known air source heat pump name in Britain, with Ecodan units assembled in Livingston, Scotland. The current R290 range reaches high flow temperatures, suiting radiator retrofits without full re-pipes. Huge installer familiarity means competitive quotes and easy servicing. Mitsubishi Electric Ecodan is best suited to homeowners who want the safest mainstream choice with the widest installer support.
What is the warranty on a Mitsubishi Electric Ecodan heat pump?
Mitsubishi Electric Ecodan backs the unit with a 7-year warranty and the compressor with 7 years (indicative; confirm the current terms for your specific model, as accredited-installer schemes often extend them). Workmanship cover for the installation itself comes separately from your installer and should be at least 12 months. Warranty claims generally require professional installation and servicing per the manual, so keep your installation paperwork and MCS certificate.
How efficient is a Mitsubishi Electric Ecodan air source heat pump?
The Ecodan R290 8.5kW carries a SCOP (seasonal coefficient of performance) of 4.3, meaning that across a heating season every 1 kWh of electricity in delivers about 4.3 kWh of heat. At Ofgem cap electricity prices (~25p/kWh) and a typical 10,000 kWh annual heat demand, that is an estimated running cost of around £580 a year, against roughly £640 to £810 for a 90%-efficient gas boiler at the 2026 cap gas rates (5.74p rising to 7.33p/kWh on 1 July 2026). Estimates, not quotes; heat-pump time-of-use tariffs can do better.
How long does a Mitsubishi Electric Ecodan heat pump last?
Mitsubishi Electric Ecodan warrants the unit for 7 years and the compressor for 7, and with an annual service heat pumps are generally expected to run well beyond their warranty period. Longevity depends on correct sizing (the MCS heat-loss survey), sensible siting and regular servicing. Confirm design life and extended-warranty options for your specific model with your MCS-certified installer.
