The UK’s slow heat pump adoption poses a significant barrier to meeting its net zero targets, with fewer than 100,000 heat pumps fitted last year compared to over 1.5 million gas boilers.
The UK’s Slow Heat Pump Adoption: A Barrier to Meeting Net Zero Targets
The Current State of Heat Pump Installations in the UK
Fewer than 100,000 heat pumps were fitted last year in the UK, compared to over 1.5 million gas boilers. This stark contrast highlights the slow introduction of heat pumps in Europe and underscores the need for accelerated adoption to meet the country’s net zero targets.
A heat pump is a device that uses refrigeration to transfer heat from one location to another.
It can provide both heating and cooling by reversing the direction of its operation.
In heating mode, it extracts heat from a source, such as the air or ground, and transfers it to a building.
In cooling mode, it absorbs heat from the building and releases it outside.
Heat pumps are energy-efficient and environmentally friendly compared to traditional HVAC systems.
Barriers to Heat Pump Adoption: Inadequate Grants and Discrimination Against Poorer Households
Poorer households are being shut out of the heat pump market due to inadequate grants. The current grant available through the boiler upgrade scheme is £7,500 in England and Wales, leaving homeowners paying an average of £5,400. This disparity disproportionately affects poorer households, with only 19% of heat pumps installed in areas classified as the poorest third of neighborhoods.
The global heat pump market is expected to reach $64.8 billion by 2025, driven by increasing energy efficiency and environmental concerns.
Heat pumps are eco-friendly alternatives to traditional HVAC systems, providing up to 4 units of energy for every unit consumed.
The European Union has set a target to deploy 30 million heat pumps by 2030, with several countries investing heavily in the technology.
Economic Inefficiencies: Distortions in the UK’s Electricity Market
Heat pumps are more expensive to run than gas boilers due to distortions in the UK’s privatised electricity market. The artificially higher energy prices for electricity compared to gas, combined with green levies that pay for renewable energy incentives, make heat pumps less attractive to households.

Shifting Levies: A Potential Solution to Make Heat Pumps More Affordable
Shifting the levies to gas bills would significantly improve the economic viability of heat pumps. This change would save most households more than £300 a year and make the switch more attractive. The Resolution Foundation recommends increasing top-up grants for low-income households, particularly those with gross income below £30,000 and non-pension assets below £500,000.
A Call to Action: Reforming the Subsidy System and Implementing New Regulations
A subsidy is a financial assistance provided by governments or organizations to support specific industries, products, or services.
The primary goal of subsidies is to promote economic growth, reduce poverty, and increase access to essential goods and services.
There are various types of subsidies, including cash subsidies, in-kind subsidies, and tax subsidies.
Cash subsidies provide direct financial assistance, while in-kind subsidies offer goods or services at reduced prices.
Tax subsidies reduce the tax burden on recipients, making it more affordable for them to access subsidized products or services.
Jonathan Marshall, a principal economist at the Resolution Foundation, emphasizes the need for targeted support for low-income households. He calls for reforming the subsidy system and implementing new regulations, such as the future homes standard, which could enforce heat pump installations in new-build homes instead of gas boilers.
Government Response: Ambitious Plan to Address Heat Pump Adoption
The Department for Energy Security and Net Zero has announced an ambitious plan to transform homes across the country. While the government’s warm homes plan aims to make homes cheaper and cleaner to run, critics argue that it does not go far enough in addressing the issue of heat pump adoption. The spokesperson for the department highlights their commitment to helping more people get a heat pump through the £7,500 grant scheme, but many question whether this is sufficient to meet the country’s net zero targets.
Conclusion
The UK’s slow heat pump adoption poses a significant barrier to meeting its net zero targets. Addressing this issue requires targeted support for low-income households, reforming the subsidy system, and implementing new regulations. The government must take concrete steps to accelerate the adoption of heat pumps and make them more affordable for all households.
