We think your home could be perfect for a heat pump
We look at a few data sources to assess whether homes are suitable, and it looks like your home may be a perfect fit to get an affordable, green heat pump for less than £1,000 (after applying the £7,500 the Boiler Upgrade Scheme grant).
We need to check a few more bits to make sure your home is eligible. All being well, you could ditch your gas for good by winter! Just get a quick quote to find out how much it'll cost for you.
Why get a heat pump?
- They’re cheaper to run: you could save hundreds of pounds a year with our Cosy Octopus tariff.
- They last longer: up to 20 years, potentially 5 years longer than a gas boiler.
- They’re more efficient: up to 4 times more efficient than a gas boiler
- They’re better for the plant: 80% less dirty emissions than gas, without compromising on comfort.
- They offer comfortable, consistent heating and hot water: we found that heat pump customers rated their heating more highly than those with a gas boiler.

Heat pumps vs gas boilers
When compared to your old gas boiler, on average heat pumps come out tops – and they can be cheaper to install.

Our claims explained
Efficiency / A heat pump is up to 4x more efficient than a gas boiler:
Heat pumps can deliver several units of heat for each unit of electricity. For every 1 kWh of electricity you put in, you could get an average of 3.1kWh heat out, which is an efficiency of 310%! This is because heat pumps don’t create heat, but move existing heat from nature into your home (like an air conditioner or refrigerator, but in reverse).
Alternatively, when you burn stuff to generate heat (like gas, oil, or wood), you are instead creating heat by converting matter to energy - so you can never get more than one unit of heat for each unit of energy you burn. Gas boilers in UK homes are only around 85.3% efficient, so for every 1 kWh of gas you put in, you get around 0.853kWh of heat out, which is nearly 4x less efficient than a heat pump (3.1/0.853 = 3.6).
These are typical install efficiencies as seen from government funded studies of gas boilers and heat pumps installed in real homes. Our own installations are typically higher efficiency than the ones shown in this study.
Cut carbon emissions by around 80% with a heat pump:
This is the typical reduction in heating carbon emissions using an electric powered heat pump compared to a gas boiler, based on the following calculation:
Gas CO2 = (A/C*D) = 2.35 tonnes
Electricity CO2 = (A/B*E) = 0.45 tonnes
Carbon saving = 1.9 tonnes or 82%
Where A - E are:
A - 9,250 MWh typical energy demand for a medium use property (according to Ofgem).
B - 3 heat pump seasonal coefficient of performance
C - new boiler efficiency of 82.5% (BEIS study)
D - Gas fuel emissions of 210 gCO2/kWh (SAP 10.2)
E - Electricity fuel emissions of 136 gCO2/kWh (SAP 10.2)

Heat pump customers rated their heating more highly than those with a gas boiler
From our research, we found homeowners with a heat pump are generally happier with their heating than those with a gas boiler.
We surveyed 2,300 customers to find out how satisfied they were with their heating system, including heat pump owners and gas boiler owners. The results showed that:
- 90% of heat pump owners were satisfied with how warm it kept their home, compared to 80% of gas boiler owners.
- Heat pump customers gave their heating system a 7 out of 10 rating in terms of cost-effectiveness, while gas boiler owners rated theirs at 6.
Heat pumps vs gas boilers
Lifespan: the expected lifespan of a gas boiler is 10-15 years, whereas a Daikin heat pump is expected to run for 15-20 years.
Heating costs: Check out our blog on heat pump running costs for a full breakdown of our running cost calculations.
Integrates with solar: If you have solar panels installed, you'll have the ability to power your heat pump on electricity generated at home.
Runs on green electricity: Heat pumps run on electricity and if you're on supply with Octopus Energy, all of our tariffs include 100% renewable electricity.
Product-specific smart tariff: If you have a heat pump installed, you'll have access to the Cosy Octopus smart tariff which is specifically designed for heat pump users.
They're cheaper to run
You can save £221 a year on heating compared to a gas boiler with the Cosy Octopus tariff, designed specifically for heat pump users.
