Previous Nesta reporting has shown  that one in ten households – 3 million in total – need to install a heat pump during the life of this Parliament to meet the UK's climate obligations. This is a twelve-fold increase from the previous Parliament, where the UK installed an estimated 250,000 heat pumps between 2020 and 2024.

Of the 25.5 million UK homes that still use oil or gas boilers – who will be the next heat pump adopters? By understanding who is likely to be next in line to install heat pumps, we can improve services and advice so they are more specific and accessible, encouraging these households to take action towards low-carbon heating. 

Previous research by Which? has already helped us to understand how people differ when it comes to heat pump adoption. They suggest that UK homeowners could be grouped into one of six categories when it comes to knowledge and willingness to install a heat pump. This project aims to provide more clarity by creating geodemographic segments of heat pump adopters – those of today, tomorrow and in five years time. By breaking this audience into segments with shared characteristics, we can better understand what would help them take the next step on their journey towards heat pump adoption. 

Note: Homeowners who have heard of heat pumps and know what they are were asked if they would consider installing a heat pump if their current heat system needed replacing in the next 12 months.

Having a more accurate idea of who the potential heat pump adopters in the UK are, including where they are located and what their needs are, will enable us to better develop and target interventions to increase heat pump adoption. For example, new projects that tailor interventions to specific segments, and social media advertising for existing services like the Get A Heat Pump website and Visit a Heat Pump service.

Creating heat pump-specific segments could enable us to more effectively provide the information people need on their heat pump journey. Experian will develop pen portraits of each segment (which can be shared with the wider sector), providing information to media agencies to more accurately target potential heat pump adopters through online marketing channels, such as Google ads and Facebook, and through offline channels, such as door drops. Ultimately, if we can speed up the rate of heat pump uptake we can move faster to scaling low-carbon heating across the country.

We commissioned data analytics company Experian to produce this detailed audience segmentation through representative quantitative research with YouGov (involving a sample of 7,000 people). Our aim was to derive demographic segments underpinned by a combination of research data, including the MCS database of existing heat pump adopters (70,000 installations) and demographics and geographical data from Experian.

Based on 30 million UK households, we’ve developed profiles of eight distinct segments at different points in their heat pump journey - from techie young families to tech-cautious pre-retirees.

Understanding these segments, their characteristics, challenges and motivations, is vital in providing tailored and effective information, services and support for people at every stage of their heat pump journey.

We will be undertaking qualitative research with members of each segment to help us develop and test messaging approaches. We'll also be looking to work with other organisations tackling home decarbonisation to help them incorporate these learnings into their communications and potential interventions.
