Our claims explained
Heat pumps vs Gas boilers
The comparisons below are based on typical UK domestic installations and published consumption and emissions data. Individual performance, costs and emissions will vary depending on property, system design, tariffs and usage.
Efficiency: A heat pump is around 4x more efficient than a gas boiler
Based on performance data from a fleet of installed low temperature Octopus Cosy heat pumps, the average Seasonal Coefficient of Performance (SCOP) is around 3.3, meaning approximately 3.3 kWh of heat is delivered for every 1 kWh of electricity used. Systems are designed to achieve an in-situ SCOP of 3.4, reflecting typical UK installations. All our heat pumps are independently tested by the Building Research Establishment (BRE), and SCOP values are published on the Microgeneration Certification Scheme (MCS) product database.
By comparison, typical UK domestic gas boilers operate at around 85% efficiency, delivering approximately 0.85 kWh of heat per 1 kWh of gas used. Boilers generate heat through combustion and cannot exceed 100% efficiency.
The comparison is based on typical real-world performance of low temperature Octopus Cosy heat pumps and typical UK domestic gas boilers. Actual efficiency varies by property, system design, and usage.
Lifespan: Heat pumps typically last longer than gas boilers
The expected lifespan of a typical gas boiler is 10–15 years. A heat pump typically has a lifespan of 15–20 years, with UK government research indicating an average of around 20 years. Manufacturer Daikin reports similar ranges. Actual lifespan depends on factors such as installation quality, maintenance, usage patterns, and operating conditions.
Running costs: Save around £300 a year with a heat pump compared to a gas boiler
Based on a predictive model for a typical medium-use home with gas supply removed and no gas standing charge, running a low temperature Octopus Cosy heat pump on our Cosy Octopus fixed tariff, compared to the same medium-use home with a gas boiler on our Flexible Octopus tariff (prices correct as of January 2026). Actual savings will vary depending on system design, tariff choice, home insulation and energy use. Based on typical Ofgem household consumption data.
See our heat pump savings blog for full details and calculations.
Emissions: Cut carbon emissions by around 80% with a heat pump
A typical medium-use home could reduce operational heating carbon emissions by around 83% using an electric powered low temperature Octopus Cosy heat pump compared to a typical UK domestic gas boiler, based on the following calculation:
Gas CO2 = (A*D) = 2.42 tonnes per year
Electricity CO2 = (A/B*C*E) = 0.40 tonnes per year
Carbon saving = 2.01 tonnes or 83%
Where A - E are:
A - 11,500 Ofgem gas consumption values for a typical medium-use home
B - 330% typical seasonal coefficient of performance from a fleet of Octopus low temperature heat pumps
C - 85% typical gas boiler efficiency from a BEIS study
D - Gas fuel emissions of 210 gCO2/kWh (SAP 10.2)
E - Electricity fuel emissions of 136 gCO2/kWh (SAP 10.2)
Based on these sources, heat pumps typically produce lower operational emissions when heating the home than gas boilers.
Save around 85% on electricity bills with solar & battery power
This estimate is based on a predictive model for a typical medium-electricity-use home installing a 10-panel solar system with a 5kWh battery. In this scenario, a home on a standard tariff could reduce their electricity bill from £943 per year to around £155 when exporting excess power on our fixed outgoing rate – a saving of £788 (around 85%).
Actual savings will vary depending on factors including your energy usage, property location, tariff type, solar system size, and whether a battery is installed.

Save 85% vs public charging when you power up at home with Intelligent Octopus Go
A slow or fast charge (<50 kWh) with one of the UK’s public charging points costs an EV driver 54p/kWh on average (last checked March 2026). With Intelligent Octopus Go, you smart charge for only 8p/kWh and save 85%.
1 - 8/54 = 0.85 or 85%
Save £820 a year on your fuel costs with an EV vs a petrol car
Save £820 a year on your fuel costs with an EV vs a petrol car
This is the difference in annual cost to smart charge an average electric car on our Intelligent Octopus Go tariff (£174) versus fueling the average petrol car (£994).
Annual cost to charge with Intellingt Octopus Go = A*B*C = 7,100 miles * 0.306 kwh/mile * 0.08 £/kWh = £173.81
Annual cost to fuel a petrol car = A*D = 7,100 miles/year * 0.14 £/mile = £994 per year
A - 7,100 average annual mileage (gov.uk)
B - 0.306 kWh/mile average electric car efficiency (EV database)
C - 8 p/kWh Intelligent Octopus smart charging rate, assuming you're smart charging for a maximum of 6 hours/day. Check if you're eligible.
D - 0.14 £/mile average cost per mile for a petrol car (gov.uk)
