EDF offers free seven-year service and warranty on Air Source Heat Pumps

Posted August 12, 2026
  • EDF is offering free seven-year service and warranty package worth £750 to customers purchasing an Air Source Heat Pump before 31st August
  • With the grant increase to the Boiler Upgrade Scheme (BUS) for households with oil or LPG, now is the perfect time to switch to zero-carbon energy 
  • With the Boiler Upgrade Scheme grant applied, customers can install a heat pump from as little as £4,100.

EDF is helping more households make the switch to low-carbon heating this summer with a new limited-time offer on air source heat pumps.

Customers who buy a heat pump via EDF will get free seven-year servicing and warranty package worth £750, providing them with added peace of mind and long-term value when upgrading their home’s heating system.

Following the update to the Government’s Boiler Upgrade Scheme (BUS) on 21st July 2026 to support households hoping to make the switch away from oil and LPG, customers are now able to install an EDF heat pump from as little as £4,100.1 

Making the switch to a low-carbon home 

With demand for low-carbon heating expected to grow as winter approaches, EDF is encouraging homeowners to act now and secure their installation ahead of the seasonal rush. 

The free seven-year service and warranty package covers whichever heat pump manufacturer customers select as part of the installation, providing them with added peace of mind and helping them to reduce the ongoing costs of owning a heat pump.2 

EDF customer saves £600 per month with low-carbon home 

Steve, an EDF customer from Somerset, has already made the switch from oil and says replacing his oil powered heating and hot water system with a heat pump was “the best thing he did”. Alongside his installation of a heat pump, he paired it with a substantial solar panel installation, making his home low-carbon. 

He said: “Our home was previously heated by oil, so we wanted a more efficient and predictable energy solution. I estimate I’m now saving around £600 per month when accounting for avoided oil purchases, no longer needing my log burner, and factoring in the export from solar generation offsetting against the cost of running our heat pump. This includes powering two EVs too!

“Working with EDF was great; they coordinated the installation of both the heat pump and solar to make sure they worked together. We wanted to create a house that was self-sufficient, and that’s exactly what we’ve ended up doing!” 

Toby Allen, Director of Business Development at EDF, said: “We’re committed to helping more customers take control of their energy costs while reducing their carbon footprint. Air source heat pumps offer an opportunity to lower household emissions and, for many homes, reduce heating costs compared with traditional heating oil and gas boilers.

“Combined with the enhanced Boiler Upgrade Scheme grant and our free seven-year service and warranty package worth £750, this summer is an excellent opportunity for homeowners who are considering making the switch ahead of the winter.”

Air Source Heat Pumps can save £146 per year on bills 

Air source heat pumps are typically 300-400% more efficient than a standard gas boiler, making them one of the most effective ways for households to reduce both their energy use and carbon emissions.3 According to the Energy Saving Trust, replacing an A-rated gas boiler with a standard air source heat pump in an average three-bedroom semi-detached home can reduce a household’s carbon footprint by around 13.4%.4

A customer switching from a highly efficient 94% gas boiler to an air source heat pump with a seasonal coefficient of performance of 3.1 could save around £146 per year with EDF’s Heat Pump Tracker Tariff, compared with the current single-rate price cap tariff.5

EDF is also referring customers to Snugg for their Carbon Cashback programme, which gives eligible solar and heat pump customers the opportunity to be paid for the carbon savings generated by their installation. Customers on the scheme have the potential to receive Carbon Cashback payments of up to £2,000 over 10 years, subject to eligibility criteria and programme terms.6

Customers can learn more about the offer for Air Source Heat Pumps on the EDF website.


1 This price reflects the BUS government grant and is based on our lowest priced heat pump, reusing a suitable existing hot water cylinder and requiring no radiator upgrades. Your individual quote will be specific to your property and requirements.

2 The limited time offer is eligible for the first 125 customers purchasing an air source heat pump system.

3 This is dependent on what system you’re replacing. To check the efficiency of your system, visit Product directory - MCS (mcscertified.com).

4 According to ONS reports, average CO2 emissions are 6 tonnes per head, and the average household size is 2.36 residents. Therefore, an average household has a carbon footprint of 14.16 tonnes per year. This equates to a 13.4% reduction in CO2 emissions if you upgrade your old gas boiler with an air source heat pump. 

5 Savings are based on a customer using Ofgem’s typical domestic consumption of 2,500 kWh of electricity and with heating provided by an ASHP with a COP of 3.1, providing equivalent heat to that from a 94% gas boiler using 9,500 kWh of gas.

6 Snugg’s Carbon Cashback programme is a project registered with Verra, the single biggest issuer of carbon credits globally. The methodology Snugg utilises has a project length of 5 years initially, followed by the possibility of two project period renewals of 5 years each. Therefore, the maximum possible crediting period for a single home is 15 years. 10 years is Snugg’s opinion of the most likely period a home enrolling in Carbon Cashback will be able to generate carbon credits and therefore receive payment. If you sell or let your home whilst enrolled in Carbon Cashback, you will no longer be able to generate carbon credits.
