Recent quantitative and qualitative evidence documents a dramatic reduction in average direct UK household energy consumption in the last decade. The ‘fuel poverty gap’ in the UK (average shortfall that fuel poor households experience in affording their energy bills) has also grown substantially in that period. Here we draw on the literature on vulnerability and on recent qualitative interviews with fuel poor households to characterise the experience of energy vulnerability in the UK. Using our qualitative data, we explore energy vulnerability from the point of view of our interviewees. In doing so we identify six challenges to energy vulnerability for the fuel poor: quality of dwelling fabric, energy costs and supply issues, stability of household income, tenancy relations, social relations within the household and outside, and ill health. In analysing these challenges we find that the energy vulnerable have limited agency to reduce their own vulnerability. Further, current UK policy relating to fuel poverty does not take full account of these challenges. Any attempt to address energy vulnerability coherently in the future must engage with structural forces (policies, markets, and recognition) in order to increase household agency for change

A household is fuel poor when it is unable to afford the level of energy services required to allow its members to live a decent life. From 2010 to 2015, the UK government transformed the politics of fuel poverty, with a new definition (‘Low income, high costs’ or LIHC), indicators and targets. Using a subjectivity framework to analyse the government documentation around LIHC, I find that: a distinction between poverty and fuel poverty is reinforced by the new politics, resulting in energy efficiency measures being prioritised as the appropriate solution. The austerity maxim of ‘helping those most in need’ is threaded through this new politics, belying an acceptance that not all fuel poverty can be alleviated. Further, LIHC underplays the role of changing energy costs, which now have no impact on the headline indicator. I argue that this new politics is symbolic, and unlikely to have positive impacts for most fuel poor households.
