The decarbonisation of domestic heating is essential for the UK to achieve net zero carbon emissions, but requires significant changes in domestic infrastructure. Public participation plays a pivotal role in this transition, yet public attitudes towards decarbonised heating remain under-researched and poorly understood. We collected a nationally representative dataset via an online survey of 2,226 individuals in Great Britain, and an additional booster sample dataset of 1,378 individuals in Scotland and Wales specifically. The survey explored attitudes to three decarbonised heating technologies currently being trialled or entering the market: heat pumps, hydrogen heating, and district heating networks. A wide dataset of interrelated variables was collected, including heating system preference and usage, knowledge and support for decarbonised heating, environmental and energy security concerns, perceptions of trust and responsibility, financial considerations, and many others. Central to the study was an informed choice decision pathway element designed to investigate key factors underlying personal willingness to adopt each technology.The UK energy system is changing rapidly. Greenhouse gas emissions fell by 43% between 1990 and 2017, and renewables now account for 30% of electricity generation. Despite this progress, achieving emissions reductions has been difficult outside the electricity sector, and progress could stall without more effective policy action. The Paris Agreement means that the UK may have to go further than current targets, to achieve a net zero energy system. Reducing emissions is not the only important energy policy goal. Further, progress need to be made whilst minimising the costs to consumers and taxpayers; maintaining high levels of energy security; and maximising economic, environmental and social benefits. There is a clear need for research to understand the nature of the technical, economic, political, environmental and societal dynamics affecting the energy system - including the local, national and international components of these dynamics. This proposal sets out UKERC's plans for a 4th phase of research and engagement (2019-2024) that addresses this challenge. It includes a programme of interdisciplinary research on sustainable future energy systems. This is driven by real-world energy challenges whilst exploring new questions, methods and agendas. It also explains how UKERC's central activities will be developed further, including new capabilities to support energy researchers and decision-makers. The UKERC phase 4 research programme will focus on new challenges and opportunities for implementing the energy transition, and will be concerned with the three main questions: - How will global, national and local developments influence the shape and pace of the UK's transition towards a low carbon energy system? - What are the potential economic, political, social and environmental costs and benefits of energy system change, and how can they be distributed equitably? - Which actors could take the lead in implementing the next stage of the UK's energy transition, and what are the implications for policy and governance? To address these questions, the research programme includes seven interrelated research themes: UK energy in a global context; Local and regional energy systems; Energy, environment, and landscape; Energy infrastructure transitions; Energy for mobility; Energy systems for heat; and Industrial decarbonisation. The proposal sets out details of research within these themes, plans for associated PhD studentships and details of the flexible research fund that will be used to commission additional research projects, scoping studies and to support integration. A first integration project on energy and the economy will be undertaken at the start of UKERC phase 4. The research themes are complemented by four national capabilities that form part of the research programme: an expanded Technology and Policy Assessment (TPA) capability; a new Energy Modelling Hub; the UKERC Energy Data Centre; and a new Public Engagement Observatory. Research within TPA and the Observatory will align and integrate with the main research themes. These four capabilities will also enhance UKERC's ability to provide evidence, data and expertise for academic, policy, industry and other stakeholder communities. The UKERC headquarters (HQ) team will support the management and co-ordination of the research programme; and will also undertake a range of other functions to support the broader UK energy research community and its key stakeholders. These functions include promoting networking and engagement between stakeholders in academia, policy, industry and third sector (including through a networking fund), supporting career development and capacity building, and enhancing international collaboration (including through the UK's participation in the European Energy Research Alliance).

The data was collected via a nationally representative online survey of the general public in Great Britain. The sample was selected via quota sampling, using nationally representative quotas for age, education, gender and region. The same procedure was applied for the booster samples which sampled from Scotland and Wales specifically, with the exception that only age, education and gender were used as the sampling quotas. All individuals sampled were over 18 and drawn from a panel provided by a third-party polling company.
