What Is Fuel Poverty In The UK? 

2 May 2025

Fuel poverty is a pressing issue affecting millions across the UK, intrinsically linked to the broader challenges of housing poverty. It’s a complex problem that goes beyond simply affording utility bills; it’s about the inability to keep a home adequately warm at a reasonable cost, leading to a cascade of detrimental impacts on health, wellbeing, and living standards.

Defining Fuel Poverty in the UK

At its heart, fuel poverty in the UK is defined primarily by the Low Income Low Energy Efficiency (LILEE) metric, particularly in England. This identifies a household as fuel poor if they have a low income and live in a home with a low energy efficiency rating (Band D, E, F, or G). Essentially, even after receiving government support for energy bills, these households would be left with a residual income below the official poverty line if they were to spend the amount needed to heat their home to an adequate standard. While the LILEE metric is the official measure in England, other parts of the UK and many charities also use a definition based on a household needing to spend more than 10% of their income on energy costs to maintain a satisfactory heating regime. Regardless of the specific metric used, the reality for those experiencing fuel poverty is a daily struggle to stay warm.

The Causes: A Perfect Storm of Factors

The causes of fuel poverty are a perfect storm of low incomes, high energy prices, and crucially, energy-inefficient homes. For many households, stagnant wages and insufficient welfare support mean that even with careful budgeting, the cost of heating their home consumes a disproportionately large chunk of their income. The volatility of energy prices in recent years has only exacerbated this, pushing more households into precarious situations.

However, a significant factor, and one often directly linked to housing poverty, is the poor energy efficiency of many properties in the UK. Older buildings, common in the UK’s housing stock, often lack adequate insulation, have inefficient heating systems, and suffer from draughts. This means that even if residents can afford to turn the heating on, much of that expensive heat is quickly lost, making it impossible to maintain a comfortable and healthy indoor temperature without excessive cost. This is where the links to housing poverty become starkly clear – those with the lowest incomes are often living in the worst quality housing, creating a vicious cycle where they cannot afford to heat their homes adequately, and their homes are inherently difficult and costly to heat.

The Impacts: More Than Just Cold Homes

The impacts of fuel poverty are far-reaching and severe. On a human level, living in a cold home has significant health consequences. It exacerbates existing respiratory conditions like asthma and can lead to new problems. Cold homes also put a strain on the cardiovascular system, increasing the risk of heart attacks and strokes, particularly among the elderly and vulnerable. Mental health is also affected, with the stress and anxiety of trying to stay warm and afford bills taking a heavy toll. Tragically, fuel poverty is a contributing factor to excess winter deaths in the UK each year. In fact, National Energy Action estimated in 2023 that 45 people died every day as a result of fuel poverty – a harrowing statistic.

Beyond the direct health impacts of cold, inadequately heated homes, fuel poverty is also closely associated with other poor housing conditions. When residents cannot afford to heat their homes properly, they may reduce ventilation to try and conserve warmth. This lack of air circulation, combined with cold surfaces, creates the ideal environment for condensation, leading to damp and mould growth. These issues not only cause further damage to the property but also release spores into the air, significantly worsening indoor air quality and posing further health risks, particularly for children and those with respiratory sensitivities.

Poverty Housing Statistics and the Scale of the Problem

Recent poverty housing statistics paint a concerning picture. Millions of households in the UK are officially classified as fuel poor, with many more living in energy-inefficient homes and struggling with energy costs. The government estimates that 13% of homes, or 3.17 million households, were deemed to be ‘fuel poor’ based on the LILEE metric as of 2023.

Data consistently shows that those in rented accommodation, both social and private, are disproportionately affected by fuel poverty and live in homes that fail to meet basic decency standards, including issues with damp and mould. Those in privately rented homes are disproportionately affected by fuel poverty, accounting for 35% of all individuals in this situation – over twice the combined percentage in local authority (8%) and housing association (10%) properties. The cost of addressing these issues is significant, not just for the individuals and families affected but also for public services, with estimates suggesting that the health costs to the NHS of cold homes run into billions of pounds annually.

Tackling Fuel Poverty

The challenges of poverty in housing and fuel poverty are interconnected and require a multifaceted approach to tackle. While increasing incomes and reducing energy prices are crucial national strategies, improving the energy efficiency of the UK’s housing stock is a fundamental long-term solution. This involves upgrading insulation, installing more efficient heating systems, and addressing structural issues that contribute to heat loss and damp.

This is where technology plays a vital role. Understanding the environmental conditions within a property is the first step to identifying and addressing issues that contribute to fuel poverty and poor housing. ResiSure’s innovative monitoring technology provides private landlords and property professionals with the data insights needed to keep properties in top condition and ensure tenant satisfaction. The small, easy-to-install, non-intrusive devices can track key metrics such as damp, mould, air quality, humidity, and even potential leaks.

By continuously monitoring these factors, ResiSure’s technology can identify potential problems early, often before they become visible or cause significant damage. High humidity levels, for instance, can be an early indicator of potential condensation and mould issues, often linked to underheating. Monitoring air quality can highlight poor ventilation. Detecting leaks promptly prevents the water ingress that directly causes damp and structural issues. This proactive approach allows for timely interventions, preventing the deterioration of properties, reducing the likelihood of damp and mould, and ultimately helping to create healthier and more energy-efficient homes.

In the context of fuel poverty, this technology is invaluable. By providing data on the conditions within a property, it can help pinpoint homes that are at risk due to inadequate heating or poor energy efficiency, even if the tenant is struggling in silence. This allows landlords to work with tenants to address the root causes, whether that involves providing advice on heating and ventilation or undertaking necessary property improvements. By improving the energy efficiency and overall condition of properties, the technology indirectly helps to lower heating costs and improve the effectiveness of the energy used, making it easier for tenants to keep their homes warm and reducing the burden of fuel poverty.
