A Samsung heat pump costs roughly £7,000 to £15,000 installed
The installed cost for a typical 8–12 kW air-source heat pump (ASHP) is £7,000–£15,000. A new gas combi boiler costs £2,500–£4,500 (Boiler Guide, 2026 industry averages). Samsung’s Gen 6 and Gen 7 models sit at the upper end of this range due to inverter technology and smart controls.
The Boiler Upgrade Scheme (BUS) grant of £7,500 can reduce your outlay to £0–£7,500 (DESNZ, 2026). Running costs can also be lower. A Samsung heat pump can cut annual heating bills by £200–£600 compared to a gas boiler, depending on the gas-to-electricity price ratio (Energy Saving Trust, 2026).
Samsung’s 2026 Gen 7 range delivers a SCOP of 4.2–4.6
Seasonal Coefficient of Performance (SCOP) measures efficiency across a full year. A higher SCOP means lower running costs. Samsung’s Gen 7 ASHP models (AE050MXADGH/EU and AE090MXADGH/EU) achieve SCOP 4.2–4.6 at a 35°C flow temperature (MCS Product Database, 2026).
For comparison, a typical UK gas boiler has an efficiency of 0.85–0.92 under SAP 2012. A SCOP of 4.5 means the heat pump uses 4.5 times less electricity per unit of heat than a gas boiler uses gas. Samsung’s Gen 6 range (2023–2025) had SCOP 3.8–4.2. The Gen 7 represents a 10–15% efficiency gain.
Samsung heat pumps qualify for the full £7,500 BUS grant from 2026
The Boiler Upgrade Scheme (BUS) offers £7,500 off the installation of an MCS-certified air-source heat pump (DESNZ, 2026). Samsung’s Gen 6 and Gen 7 models are all MCS-certified (MCS Product Database, 2026).
Eligibility requires your property to have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation (GOV.UK, 2026). The grant is applied directly to the installer, so you pay the net price.
Samsung heat pumps come with a 7-year parts-and-labour warranty
Samsung offers a 7-year warranty on the outdoor unit (compressor and heat exchanger) for domestic installations registered within 30 days (Samsung UK, 2026). Labour coverage varies by installer. Most MCS-registered firms add 1–2 years of labour cover, so check individual quotes.
For comparison, Vaillant offers 5–7 years, Daikin 5 years, and Mitsubishi Electric 5 years (manufacturer websites, 2026). The Samsung warranty is transferable to a new owner if the property is sold within the period.

Samsung heat pumps are compatible with both radiators and underfloor heating, but radiators may need upgrading
Samsung heat pumps operate at a lower flow temperature (35–45°C) than gas boilers (60–75°C). Radiators must be sized to emit enough heat at these lower temperatures. Most existing radiators (Type 11 or 22) in UK homes are undersized for heat pumps. Upgrading to larger radiators or fan-assisted models costs £1,000–£3,000 for a typical 3-bed house (Heat Pump Association, 2026).
Underfloor heating (UFH) is the ideal partner because it runs at 30–35°C and has a large surface area. Samsung’s ‘Smart Pre-Heating’ function on Gen 7 models can raise flow temperature temporarily to meet peak demand, reducing the need for full radiator replacement (Samsung technical specs, 2026).
The installer must be MCS-certified and registered with TrustMark to qualify for the BUS grant
The BUS grant requires the installer to be MCS-certified (Microgeneration Certification Scheme) and registered with TrustMark (DESNZ, 2026). Samsung does not have its own installer network. Use the MCS Installer Database or TrustMark’s ‘Find a Tradesperson’ tool to verify credentials.
Check the installer’s MCS certificate number and confirm it covers ‘Air Source Heat Pumps’ (MCS, 2026). Also confirm the installer will register your Samsung warranty within 30 days of installation.
For most UK homes, a Samsung heat pump will cut annual heating bills by £200–£600 compared to a gas boiler
Based on a typical 3-bed semi-detached house with gas heating at 12,000 kWh per year, a Samsung Gen 7 (SCOP 4.4) uses 2,727 kWh of electricity at 24p/kWh. This equals £655 per year. Gas at 6.5p/kWh costs £780 per year (Energy Saving Trust, 2026). The £125 saving is at the lower end.
With a higher SCOP (4.6) and a time-of-use tariff like Economy 7 at 15p/kWh, the saving can reach £600. If the home has a heat pump and solar PV (3.5 kWp), you can self-consume around 30% of generation, saving a further £150–£250 per year (Solar Energy UK, 2026). The biggest variable is your current heating system. Old oil or LPG boilers are much more expensive to run, so savings are higher.
