Benefits of an Air Source Heat Pump: A Guide for UK Homeowners

The UK is increasingly turning to heat pumps for our home heating needs, with an ambitious Government aim to have 450,000 installed per year by 2030. But what benefits can a heat pump bring to homeowners? If you’re considering a heat pump for yourself, our experts can help you decide. We've compiled a list of heat pump advantages you can enjoy when making the switch.

If you’re keen to learn even more about heat pumps, our expert heat pump guide covers everything you need to know.

5 advantages of installing a heat pump

1. A heat pump reduces your carbon emissions

One of the biggest benefits of heat pumps is that they operate using electricity and don’t directly emit carbon dioxide, making them much more environmentally friendly than traditional heating systems. In fact, according to the English Housing Survey 2033-2024, they can cut carbon footprint by 70% compared to a gas boiler,and this will only increase as the electricity grid decarbonises. 

As for how much electricity you’ll use, an air source heat pump’s kWh usage is typically between 2000 and 6000 per year, depending on home size, and you can help keep usage low through measures like home insulation. You can even combine certain heat pumps with solar panels for an even greater reduction in carbon emissions.

2. Heat pumps are energy efficient

When we look at the efficiency of a heat source, we compare the amount of energy used to the amount of heat energy produced. A typical gas boiler is less than 100% efficient, meaning the gas energy input exceeds the heat energy output.

On the other hand, heat pumps are typically 300% efficient, producing heat energy that is three times the electrical energy used. They can even be more efficient, with our Logic Air heat pump achieving525% efficiency in lab-tested conditions. This is lower in actual practice, but is still impressively high. This efficiency means your home’s carbon emissions are reduced even further because your heat pump requires less electricity. Another factor to consider in heat pump efficiency is SCOP, which stands for ‘seasonal coefficient of performance’. While heat pump efficiency can drop somewhat in particularly cold weather, it remains higher than a boiler's. The SCOP gives you the average efficiency over the full year.

3. Heat pumps are low-maintenance

Another advantage of air-source heat pumps is their low maintenance. Simply ensure they aren’t obstructed, clean them occasionally, and have them serviced by a professional engineer annually to keep them in tip-top condition. Air source heat pump life expectancy is also around 15-20 years, or sometimes more, meaning you won’t have to worry about a replacement for quite a while.

4. Heat pumps are eligible for grants

Another appealing aspect of heat pumps is that they are eligible for grants and schemes that significantly lower the installation cost.

The Government’s Boiler Upgrade Scheme can shave up to £9,000  off the cost of your heat pump if you’re replacing an oil-fired or LPG boiler, and £7,500 off the cost of a gas-fired boiler. This scheme is now in place until 2030 and has received additional funding thanks to record application demand. The scheme is also now easier to apply for, as loft and cavity wall insulation are no longer required for eligibility. 

The Boiler Upgrade Scheme isn’t the only financial support available for buying a heat pump. Multiple banks offer special green home mortgages and loans, including Nationwide’s Green Additional Borrowing Mortgage and Barclays’ Greener Home Reward.  See our guide explaining heat pump costs for more information on funding and tariffs. 

5. Why invest in a heat pump now rather than waiting? 

Are heat pumps just a phase? Absolutely not. Heat pump installations are consistently reaching record highs year-on-year.

As heat pumps become more commonplace, they may become a key selling point when selling a home. Potential buyers will be keen to have all the benefits, perhaps without having to install one themselves - particularly if the boiler upgrade scheme has ended.

The Ideal choice for the future

While weighing the pros and cons of air source heat pumps is important, the advantages, in terms of efficiency, cost savings, and environmental impact, are clear and compelling.

Potential disadvantages can be readily addressed through Government grants and proper home insulation. For most UK homeowners, a heat pump is a responsible, forward-thinking, and financially sound investment.
