Abstract

This dissertation investigates the socioeconomic factors influencing the retrofitting of Air Source Heat Pumps (ASHPs) in post-war residential buildings, focusing on Portsmouth, UK. The research aims to identify the barriers and opportunities associated with ASHP adoption in older housing stock, which is
crucial for meeting the UK’s carbon reduction targets. The research revealed that numerous residential buildings had inefficient heating systems, which highlighted energy inefficiency. Installing ASHPs in these houses could effectively reduce carbon emissions. However, socioeconomic factors significantly impacted the feasibility and acceptance of these initiatives.
A mixed-method approach was used using a systematic literature review and surveys aimed at homeowners and council representatives. The literature examined ASHP technology, including its advantages and challenges in retrofitting it in older buildings. The survey data, obtained via questionnaires, provided valuable insights into homeowners’ perspectives, knowledge, and financial considerations related to ASHP retrofitting. It also explored the significant impact of Portsmouth's local government policies and support systems on facilitating or hindering retrofitting activities.
The findings reveal that the obstacles to ASHPs include a high initial cost mentioned by 92% of respondents, and the lack of knowledge, indicated by 69% of participants, was compounded by technical hurdles. Homeowners with high incomes and more knowledge are more likely to retrofit their homes than individuals with lower socioeconomic status who face significant barriers to home improvement. The study emphasised the importance of government initiatives, such as grants and subsidies, in increasing accessibility to ASHP retrofitting, with 77% of respondents expressing their motivation. Nevertheless, 92% of respondents had never engaged in government and council initiatives. Local authorities can bolster adoption by raising public awareness, providing financial assistance, and collaborating with installers.
Ultimately, the study underscores the need for educational initiatives and focused policies. These factors are essential for overcoming socioeconomic obstacles and ensuring fair access to energy-efficient technologies in older housing stock. The results offer suggestions for stakeholders and policymakers to assist in the shift towards low-carbon heating systems in Portsmouth and comparable situations.
