With the shift towards net-zero carbon emissions, there’s a growing interest in sustainable heating solutions across the UK. Heat pumps are a big part of this conversation, offering a low-carbon alternative to traditional gas boilers. That said, many homeowners still have questions about the potential benefits of heat pumps.
What are Heat Pumps and How do they Work?
Heat pumps are an energy-efficient technology that is designed to provide heating and cooling for homes. They work by transferring heat from one place to another rather than generating it directly. In this way, they are fundamentally different from traditional boilers.
Air Source Heat Pumps (ASHPs)
These extract heat from the air outside, even when temperatures are as low as -15°C. Then, the heat is compressed to a higher temperature and transferred into your home for space heating and hot water. For most homes, these are accessible and affordable options, as they are cheaper to install and require less space.

What are the Advantages of Heat Pumps?
1. Energy Efficiency
One of the biggest benefits of heat pumps is their energy efficiency. For every unit of electricity consumed, a heat pump can produce three to four units of heat. This translates to an efficiency rate of 300-400%.
2. Reduction in Carbon Emissions
Heat pumps are a greener choice for homeowners who might be keen on reducing their carbon footprint. According to the Energy Saving Trust, switching to a heat pump from a gas boiler could reduce your home’s carbon emissions by up to 2,900kg of CO2.
3. Eligibility for Government Incentives
The UK government has introduced various schemes to encourage the adoption of heat pumps. One such initiative is the Boiler Upgrade Scheme (BUS). This gives homeowners across the UK grants of up to £7,500 towards the cost of installing an ASHP. This can make heat pumps a more attractive option by offsetting some of the upfront costs.
4. Longevity and Low Maintenance
Speaking generally, heat pumps have a longer lifespan than traditional boilers. Typically, they can last up to 25 years when maintained properly. They also tend to require less frequent servicing, which brings down long-term maintenance costs. With no need for annual checks, heat pumps can also be a more hassle-free option, too.
5. Versatility and Comfort
Heat pumps provide consistent heating throughout the year and can also function as cooling systems in the summer. This versatility helps to ensure comfort all year round. What’s more, heat pumps work extremely well with underfloor heating systems, and can be controlled via a remote.
What are the Costs Associated with Heat Pumps?
1. Installation Costs
The upfront cost of installing a heat pump is one of the biggest considerations. The initial payment can be considerably higher than that of fitting a traditional gas boiler and can vary significantly depending on the size of your property and the complexity of installation.
That said, it’s important to note that the available government grants can make this more manageable.
2. Running Costs
While the installation costs might be higher for a heat pump than a boiler, over time this will be recouped through lower running costs. The higher efficiency and lower energy consumption mean that a well-insulated, three-bedroom home could save £240 if switching from a gas boiler or as much as £1,000 if switching from older electric storage heaters.
What to Consider Before Installing a Heat Pump.
Home Insulation
Home insulation is more important for the efficient operation of heat pumps than it is for gas boilers. Where a gas boiler can quickly generate high temperatures, heat pumps work best when they can maintain a steady, low-level heat. Poorly insulated homes might not see such notable benefits from heat pumps as a result.
Space Requirements
Air source heat pumps need outdoor space for installation. Typically, this needs to be against an external wall and is generally appropriate for most houses and flats in the UK.
Planning Permission
In almost every case, heat pumps will fall under permitted development rights, so you won’t need planning permission. The exceptions might be if you live in a listed building or a conservation area. If so, it’s worth checking with your local authority before proceeding.
What is the Future of Heat Pumps?
The UK government has outlined plans to phase out new gas boilers by 2035. Heat pumps are expected to play a central role in the future of heating in the UK. As technology advances and economies of scale are achieved, the cost of heat pumps is likely to come down, making them more accessible for homeowners.
