Air Source Heat Pump Costs 2022 Josh Jackman Last updated on 11 August 2022 8 min read ✔ An air source heat pump usually costs around £10,000✔ The Boiler Upgrade Scheme will knock £5,000 off the total cost✔ A heat pump typically saves you £1,760 overall, compared to a gas boilerAir source heat pumps are an incredibly efficient, renewable source of energy – in fact, getting one could cut your carbon footprint by 44%.They’re easy to buy, get installed, and understand. An air source heat pump simply takes the air from around your home, and converts it into fuel to heat your home and hot water.It requires three times less energy than a gas boiler to do the same job, on average – and if you power it with 100% renewable electricity, it’ll be a completely green machine.With a gas boiler ban coming soon on new homes, it’s worth considering the best alternative on the market – especially as it costs no more than a gas boiler over its lifespan.If you're ready to embrace heat pumps, pop a few details in our easy-to-use tool, and we’ll put you in touch with experts in your area who will give you free heat pump quotes. That way, you’ll receive the best deal for your property.What’s on this page? 01 How much does an air source heat pump cost? 02 Air source heat pump cost calculator 03 Running costs 04 How can an air source heat pump make you money? 05 Service costs 06 Next steps How much does an air source heat pump cost?An air source heat pump costs a large amount at first – around £10,000 – but as with any long-term investment in your home, you have to spend money up front to make a difference.The typical air source heat pump owner will cut their emissions by 44% per year, according to calculations we've made using data from the Energy Saving Trust and the government.And you'll also save £48 per year compared to gas boiler owners, so you don't have to pay any extra to follow your green principles. Air source heat pump installation costsThe average air source heat pump costs around £10,000 to buy and install, according to the Energy Saving Trust – not ideal, considering 69% of people rank cost as the most important factor when evaluating which low-carbon product to purchase.However, you may have to install underfloor heating, better insulation, or new radiators that are 2.5 times bigger than regular ones to take full advantage of your new heat pump's abilities.You may not need to replace all your radiators, but most homes should expect to replace one-third of them.This is because a heat pump releases heat at a lower level than a gas boiler, over a longer period of time.Their slow-release nature is a large part of why they're more energy-efficient, but means you either need large surface areas in your heating equipment, or insulation that holds onto the warmth your heat pump generates.You should hire a specialist to install the heat pump and any extra equipment – it’s a complicated process that only experts should take on, and it’s easy enough to find one.They’ll also be able to explain to you how to use it easily and efficiently.You might also be able to qualify for one of the UK government grants to cover some of the cost. Air source heat pump running costsAn air source heat pump costs £1,132 per year to run, on average, which is more it would currently cost to run a gas boiler – but that won't be the case forever.Let’s dive into how we reached that figure.The average home uses 12,000kWh for heating per year, according to the latest Ofgem data.Fortunately, the typical air source heat pump produces three units of heat energy for every unit of electricity it uses, largely because water holds onto more heat than air.Where your pump falls on this scale is called its Coefficient of Performance. With three units of heat produced for every unit of energy, its efficiency rate will be 300%.If your pump is your sole heating system, that means you’ll only need to use 4,000kWh of electricity to produce the 12,000kWh of heat needed to heat the average home over a year.However electricity’s average price is currently 28p per kWh according to Ofgem, while gas only costs a relatively low 7p per kWh. That’s four times higher.So one factor reduces your costs by 300%, while the other increases your costs by 400%, meaning you'll pay slightly more in energy bills.Instead of paying £888 per year with a typical gas boiler, you’ll pay £1,132 with an air source heat pump – but that's not the end of the story.A gas boiler needs to be replaced every 10 years, while a heat pump typically lasts for 20 years or more. Avoiding that extra boiler cost of £4,000 means you'll actually save £1,760 overall by opting for a heat pump.You can also save on your air source heat pump installation, thanks to the government's Boiler Upgrade Scheme.If you want to take advantage of this grant, just enter a few details about your home into our easy-to-use quote tool. We’ll pass on your details to our specialist suppliers, who’ll send you free heat pump quotes for you to compare. How can an air source heat pump make you money?Boiler Upgrade SchemeIn April 2022, we entered the era of the Boiler Upgrade Scheme.Homeowners in England and Wales are now able to get £5,000 off the cost of a new air source heat pump, and £6,000 off the price of a ground source heat pump.This government grant will reduce the barrier to entry for anyone who would struggle to pay £10,000 to overhaul their heating system.It's the main reason why the average home will be able to save money over a heat pump's lifetime.Unfortunately, it's received a disappointingly low level of financial backing from the government.With £450 million available, a maximum of 90,000 of the UK's 27.8 million households will be able to take advantage – a tiny 0.3%.So rush to take advantage, before the funding runs dry.Renewable Heat IncentiveThe Renewable Heat Incentive (RHI) ended on 31 March 2022.If you successfully applied for the RHI before then, you'll continue receiving payments – but for everyone else, this opportunity has passed.The scheme handed out quarterly payments for seven years, based on the amount of electricity a heat pump was estimated to be producing.The last RHI tariff was a hefty 10.92p per kWh.That was a fantastic return, considering the Smart Export Guarantee only pays solar panel owners 7.5p per kWh – at most. Air source heat pump service costsIf you carry out regular maintenance checks, your heat pump should provide you with warmth and hot water for at least 20 years, according to the Energy Saving Trust.You should have the machine serviced by a professional every two or three years, to make sure everything is working at peak efficiency.This service will cost around £150, so check with your installer or the manufacturer if you can get a cheaper regular maintenance included in your purchase agreement.And before the heat pump is installed, ask your installer to write down any maintenance checks you should carry out on a regular basis.This list will include simple tasks like sweeping any leaves, dust, or snow from the heat pump’s fans, and cleaning the filter.This will save you money in the long run by keeping your heat pump functioning efficiently – and since you can take care of them yourself, it’s free.As well as carrying out maintenance checks, one way you can protect your heat pump system is by getting a heat pump cover for the outside unit, which can guard it against extreme weather conditions. Next stepsAn air source heat pump is an investment in a cheaper, greener future.Buying one will reduce your carbon footprint by 2.6 tonnes of CO2 per year, on average. That’s 44% of the average Brit’s emissions – and it'll cost you slightly less than a gas boiler would over the next 20 years.With sales of new gas boilers set to be banned from 2035, air source heat pumps are going to become increasingly popular on these shores – and further afield.By 2030, 22% of homes in America, Europe, and northern Asia will have air source heat pumps, according to the International Energy Agency.Welcome to the future.Want to start cutting your emissions as soon as possible?
