This heating system is only growing in popularity, with 2025 being a “record-breaking” year for heat pump installations, according to the government website. This comes as no surprise, considering it’s easier and more affordable than ever to install one in your home, with energy provider E.ON Next offering 0% APR finance for up to two years.
Tempted by the idea of an air source heat pump but want to learn more first? Below, we’ve rounded up five key benefits you could take advantage of.
Get a government grant of up to £7,500
Did you know that you could get up to £7,500 towards an air source heat pump as part of the government’s Boiler Upgrade Scheme? So, if the only thing stopping you from installing one in your home was the upfront cost, this is your sign to reconsider. The best part is that E.ON Next will handle your application for you, saving you the time and effort.
Once the Boiler Upgrade Scheme grant has been applied, you can expect to pay around £5,000, based on average prices of around £12,000 before funding, according to E.ON Next's website. This is all part of the government’s Warm Homes Plan, which aims to help families save on their bills and produce cleaner energy.
Get 0% APR finance with E.ON Next
E.ON Next has made heat pumps even more accessible by offering 0% APR finance for up to two years, which helps to make those payments more manageable – without having to worry about high interest rates.
To give you a rough idea of what you might expect to pay, it usually costs around £5,000 to install a heat pump and hot water tank in a three-bedroom house once the Boiler Upgrade Scheme grant has been applied. This could also include new radiators if the bespoke design and survey deem that they are needed.
Existing E.ON Next customers get up to £200 off
If you are an existing customer on an E.ON Next Tariff, you could also benefit from an additional discount of up to £200, helping to reduce upfront costs and make a heat pump more affordable.
Reduced long-term energy bills
According to E.ON Next, heat pumps are 300–400% efficient, meaning they generate three to four units of heat for every unit of electricity they use. When you compare that to A-rated boilers, which are only 90% efficient, it becomes clear why they’re a no-brainer for those looking to reduce their energy bills in the long term.
You could save up to £260 per year by replacing an old G-rated gas boiler, or up to £700 per year for an old G-rated LPG boiler, according to the Energy Saving Trust¹ .
Boost the value of your home
Installing a heat pump is a fantastic way to future-proof your home and it could even add to the value, according to the government's Cleaner Air Campaign. So, not only can you enjoy lower running costs in the short and medium term, but it’s also a decision you can feel good about for the future.
As a recap, it’s clear that there are many benefits to installing an air source heat pump in your home – and with E.ON Next’s 0% APR financing options and existing customer discount, it's an affordable choice.
