Spread the cost with monthly payments
(Subject to status and affordability)
A finance package means you could spread the cost of your air source heat pump installation with manageable monthly payments. Below is an illustrative representative example of what your typical repayments could look like over 5 or 10 years.
If you live in Scotland, you can apply for an interest-free loan of up to £7,500 through Home Energy Scotland.
Finance available at a fixed 9.9% APR representative, subject to status and credit check. The amount to be financed will vary depending on the heat pump required for your property and your chosen deposit.

Operating costs
You could save up to £290 a year on your energy bills (4) if replacing an old G-rated gas boiler and could see comparable energy bills if replacing a new A-rated gas boiler. If you’re replacing old electric storage heaters, however, you could be saving £1,000 per year on your energy bills. Heat pump efficiency fluctuates throughout the year, so you should look at the average for the whole year to get an accurate figure for cost. What’s more, with heat pump tariff’s such as those from EDF, you could also make further savings (3).
The per-unit cost to run an air source heat pump can be as little as zero if the heat pump is being powered by renewable, on-property sources such as solar panels. It is however important to remember that actual costs are difficult to pin down as they depend on how the heating system is used, how well it’s been installed, the efficiency of the system, and the heat loss profile of the home.
Future proof your property
Opting to invest in a heat pump while government grants such as the Boiler Upgrade Scheme are still available is a great way to get ahead of the curve and future-proof your home.
The average effective operational life of an air source heat pump is at least 25 years. Compared to the average efficient operational life of a gas boiler of 10 years, the investment is seen by many as the perfect balance of clean, green energy, comfortable set-it-and-forget-it heat, and long-term value-building for their property. With our heat pump promise (6), we promise that if your heat pump doesn’t perform as promised, we’ll give you a refund (Terms & Conditions apply).
Investing in solar panels and domestic batteries alongside your heat pump upgrade could mean you are energy self sufficient. This not only moves you away from paying energy bills again, but could add significant value to your property. It’s far more desirable to buy a property where you won’t have to worry about paying energy bills or a cold winter.

Zero standing charges
3. Zero standing charge for 12 months. Unlock £360 in savings with EDF Energy's Heat Pump & Save Tracker tariff. https://www.edfenergy.com/heating/electric/air-source-heat-pump £164 of savings are based on a customer using Ofgem’s typical domestic consumption of 2700 kWh electricity and with heating provided by an air source heat pump with a coefficient of performance (CoP) of 3.1 providing equivalent heat to that from a 94% gas boiler using 11,500 kWh of gas. A further £196 of savings based on 0p per day electricity standing charge based on the Q2 Ofgem price cap using a regional average. Total saving of £164 + £196 = £360.

The running cost you can expect will depend on the size of your home, any heating system upgrade and any saving will also depend on the fuel type being replaced. You can expect the saving to range between old and new, depending on the age of your current heating system.. https://energysavingtrust.org.uk/advice/air-source-heat-pumps/
