With roughly 360,000 heat pumps currently installed across the UK, the country remains a long way off the government’s target of installing 600,000 heat pumps every year by 2028, as laid out in the Energy Security Bill. But where do people currently stand on their journey toward using heat pumps? What barriers are holding back wider adoption, and how do these challenges vary across society? Most importantly, what can be done to overcome them?
Nesta’s new audience research helps to answer these questions by providing a segmentation of UK households based on demographic data, their housing situation and attitudes towards heat pumps. Ranging from “eco, high-earning Gen x-ers” — of whom 3% say they already have a heat pump — to “social tenants on tight budgets”, the report identifies the biggest heat pump enablers and barriers for each group to help them adopt the new technology.
And help is urgently needed: As Climate Barometer data shows, public knowledge of heat pumps remains limited, with only 37% of Britons knowing what a heat pump looks like, 22% saying they can describe how a heat pump works, and just 17% having heard mostly good things about them. Alongside this, 1 in 5 Britons have heard and agree with the statement that “heating technologies to replace gas boilers are untested and unreliable”, compared to only 1 in 10 who have heard the argument and disagree with it.
But for heat pumps to become a widely adopted source of heating over the next couple of decades in the UK, it will require more than fixing their image problems. Those who would already consider switching to a heat pump need to be supported to do so practically, and those who are currently unable to or hesitant about installing them need safe assurances that heat pumps will actually improve their comfort and help lower their energy bills over time.
While Climate Barometer tracker data shows that overall public awareness about heat pumps is low, it seems that misinformation runs through what the public do claim to know about heat pumps.
An article from Carbon Brief summarises the top myths about heat pumps circulating among the British public and media discourse, including that 24% think running a heat pump costs more than a gas boiler, and 20% think heat pumps only work in new homes (Good Energy poll).
In a survey of 2000 people, researchers at Cardiff and Bath universities explored public support for low carbon heating technologies (including heat pumps), and the factors that influence this support.
The survey found the majority of the respondents had at least a small amount of knowledge about low carbon heating options, and when provided with further information, held favourable views. Heat pumps (likely due to their prominence in policy discussions) were identified as the low carbon heating technology with the highest level of support.
Concerns about energy security, and pro-environmental attitudes were two factors which led to higher support for heat pumps. But the research also uncovered another important driver: knowing someone who has already had one installed.
Dubbed the ‘social circle effect’, people’s willingness to adopt low carbon heating options increased if they knew even one person who already had a heat pump.
Has support for net zero risen or fallen since the election?
Following the General Election, there is a clear uptick in support for the country’s net zero targets. Support for net zero by 2050 is at its highest point in almost 2 years, yet enthusiasm for some flagship policies hasn’t yet caught up.
