Retrofit information challenges and potential solutions: Perspectives of households, retrofit professionals and local policy makers in the United Kingdom

Rapidly scaling up energy retrofit for existing buildings is critical to help meet climate targets. Information is frequently identified as a key barrier to residential retrofit. This paper explores the role of information sharing in accelerating retrofit market transformation, through interviews and photo elicitation with homeowners ( N = 9) and two workshops with stakeholders ( N = 33) in a local authority retrofit project in Gloucestershire (UK). Findings are thematically analysed and suggestions for future local and national policy action are identified. The research finds that even for engaged, knowledgeable homeowners, accessing appropriate information is still a significant retrofit barrier. Two themes around the nature of information and information delivery are identified and key issues include information overload, a lack of context-specific information and in-person engagement, and a need for trustworthy, local information sources. Local authorities have potential to act as trusted intermediaries for structured, relevant retrofit information but require support from national governments to increase capacity and resources at local levels. National governments also have a critical role in providing clear and consistent messaging and leadership on the importance and benefits of retrofit. Policies around financial incentives are not sufficient alone and must be accompanied by strategies to overcome informational and other barriers if retrofit is to be accelerated in this decisive decade for climate action. • Informational barriers to the transformation of retrofit markets are categorised. • Views of homeowners, retrofit professionals, and local policy makers are analysed. • A novel photo elicitation method adds value to workshop and interview data. • There are barriers for both the nature of information and for how it is delivered. • Local and national policy has an important role to reduce informational barriers.
