There are many factors that contribute to whether you’ll be able to save money on your energy bills, such as:
- your electricity tariff
- the type of heat pump you install
- the design of your central heating system
- your location and its average air or ground temperatures throughout the year
Savings on your energy bill will also depend on the system you're replacing. According to Energy Saving trust, if you are replacing an old (G-rated) gas boiler with an air source heat pump, you could save you up to £395. However, if you have a modern A-rated boiler then a heat pump may cost slightly more per year to run by around £80.
