Worcester Bosch air source heat pump FAQ
How much is a Worcester Bosch air source heat pump installed in the UK (2026)?
A Worcester Bosch 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 (CS7400iAW 7kW, 7kW heat output) starts around £9,000 pre-grant; the largest (CS7400iAW 7kW, 7kW) tops out around £13,500. Combi-to-cylinder conversions and radiator upgrades add to these figures, so always confirm with a written quote.
Is a Worcester Bosch 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 Worcester Bosch a good air source heat pump brand?
Britain's most trusted boiler brand, now applying that dealer network to heat pumps. For households who have run Worcester boilers for decades, the familiar badge and installer base de-risk the switch. Bosch-owned, Worcester-based. Worcester Bosch is best suited to loyal boiler customers who want the same badge on the wall and the same engineer network.
What is the warranty on a Worcester Bosch heat pump?
Worcester Bosch 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 Worcester Bosch air source heat pump?
The CS7400iAW 7kW carries a SCOP (seasonal coefficient of performance) of 4, meaning that across a heating season every 1 kWh of electricity in delivers about 4 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 £625 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 Worcester Bosch heat pump last?
Worcester Bosch 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.
