Gas boilers have been the go-to heating system for many UK homes for decades. Yet with the UK government’s most recent update of the Boiler Upgrade Scheme, the grant level for air source heat pumps and ground source heat pumps jumped from £5,000 and £6,000 to £7,500. This makes it a more affordable time than ever to replace a boiler with a heat pump.
This article will shed some light on the benefits of heat pumps as a gas boiler alternative, factors to consider when choosing a heat pump, as well as government incentives available to help with the cost of installation.
Yet even if you’re sure about the prices, finding a reliable installer is a daunting chore. Searching for the best engineer and deals might stretch for days and weeks. What if you don’t have that much time to spare? It’s highly unlikely you’re keen on spending your whole weekend searching for installers instead of having quality family time.

Heat pumps and gas boilers are two popular ways to heat homes. However, unlike heat pumps, boilers don’t have cooling capabilities which presents a key difference between the two systems.
Let’s compare other cruical differences between heat pumps and gas boilers.
|Feature||Heat pump||Gas boiler|
|Efficiency||More efficient||Less efficient|
|Fuel||Uses electricity to transfer the outside heat to the inside||Burns natural gas to produce heat|
|Space||Requires space for an outdoor unit||Might require extra indoor space for a hot water cylinder|
|Environmental impact||More environmentally friendly||Produces carbon emissions|
|Versatility||Can heat and cool your home||Can only heat your home|
|Longevity||Up to 25 years||Up to 15 years|
Speaking of efficiency, heat pumps show a coefficient of performance (CoP) between 3 and 5 meaning that heat pumps generate between 3 and 5 units of heat for every electricity unit they use. Whereas gas boilers achieve a CoP of around 0.9 making heat pumps a more efficient heating solution.
In terms of costs, heat pumps require a bigger upfront investment. For example, ground-source heat pumps, apart from the heat pump itself, need underground loops or boreholes which definitely contribute to the installation total.
Yet, even though the cost to replace a gas boiler with a heat pump seems like a major disadvantage, switching a heat pump for a boiler brings multiple benefits.
In general, heat pumps are a more efficient, environmentally friendly, and versatile way to heat and cool your home than gas boilers. If you are considering replacing your old boiler, consider installing a heat pump.
Heat pumps have a number of advantages over gas boilers, including:
In addition to the advantages listed above, there are multiple heat pump grants, which can help to reduce the upfront cost of installation.
There are a number of considerations to keep in mind when replacing a gas boiler with a heat pump, including:
As of October 23, 2023, the UK government grants eligible homeowners £7,500 off an air source and ground source heat pump installation within the Boiler Upgrade Scheme.
These are the crucial topics to discuss with the heat pump installer as they are a deciding factor while choosing the right heat pump solution for your home and calculating the bottom line.
If you are considering replacing your gas boiler with a heat pump, it’s recommended to do your research and get quotes from multiple heat pump installers. This will help you to make the best decision for your needs and budget.
However, how long does it take to find an installer you can trust? This process can march on for weeks until you find an experienced engineer in your area. Thankfully, GreenMatch offers a less stressful alternative.

The cost to replace a gas boiler with a heat pump depends on the heat pump type, the size of your property, and the existing pipework.
Let’s compare current average prices installed for gas boilers, GSHP and ASHP solutions.
|Type of heating system||Upfront cost range||Installation cost range||Costs granted by the Boiler Upgrade Scheme|
|Air source heat pump||£8,000–£18,000||£350–£1,700||£7,500|
|Ground source heat pump||£14,500–£45,000||£700–£2,450||£7,500|
As you see, the Boiler Upgrade Scheme can significantly reduce the cost of air source heat pumps, for example. So don’t neglect getting information on existing grants and government incentives is essential for your project.
As of 2023, the UK government offers several incentives to reduce costs while replacing a gas boiler with a heat pump. Here are some key schemes for you to consider:
For example, if you choose a £10,000 air source heat pump for your home, the Boiler Upgrade Scheme grant reduces the ASHP cost to an average boiler installation of £2,500.
A local heat pump installer could walk you through the application process and provide you with tailored calculations of how those grants can help you with the initial investment.
As mentioned above, air source heat pump installation requires a way higher initial investment than what’s needed for a gas boiler. Also, it’s crucial to remember that gas boilers provide heating options only.
So if you involve an air conditioning unit to cool your home in summer, consider switching to an air source heat pump. Ultimately, you’d spend less on air source heat pump costs than on both a gas boiler and an air conditioning unit combined.
A typical UK 3-bedroom household could expect the following yearly costs to run a gas boiler, an air-source heat pump, and a conditioning system.
|System||Yearly running cost|
|Air source heat pump||£1,360|
|Air conditioning unit||£400|
Yet, these are just rough estimates and the actual running costs will vary on a bunch of factors like energy prices, your property size, energy consumption, the climate you live in and the efficiency of your heat pump. Consider talking to a professional heat pump engineer for more tailored advice.
When replacing a gas boiler with a heat pump, consider factors like energy efficiency, cost savings, upfront expenses, payback time, long-term investment, environmental impact, and available government incentives.
Heat pumps are generally more energy-efficient and cost-effective in the long run compared to gas boilers, even though electricity is more expensive. The payback period for an air source heat pump varies based on factors like installation costs, efficiency, energy usage, and incentives, typically ranging from 5 to 15 years.
For example, the upfront cost of an air source heat pump installation can be higher, ranging from £8,000 to £18,000 depending on the type and additional expenses. But heat pumps are environmentally friendlier, being 3-4 times more efficient than gas boilers and offering 3 to 5 units of heat for every unit of electricity used.
Government programs, such as the Boiler Upgrade Scheme, will provide £7,500 worth of grants to cover heat pump installation costs and reduce your initial investment.
In the end, the decision to switch from a gas boiler to a heat pump depends on your unique circumstances and priorities. While heat pumps may have higher initial costs, they offer long-term savings and environmental benefits. It’s crucial to carefully consider all these factors and conduct thorough research before making a decision.
