Consumer Vulnerability and Fairness in the Energy Transition

Introduction

The energy transition promises a cleaner, smarter, and more flexible system, but it also brings new risks and challenges—especially for the most vulnerable in society. As the GB energy market evolves, ensuring that no one is left behind is a central concern for policymakers, regulators, and industry. The events of 2021–2022, with soaring prices and widespread supplier failures, have underscored the importance of fairness, affordability, and targeted support. In this article, I’ll explore the landscape of consumer vulnerability in the energy market, the policy and regulatory frameworks designed to protect and empower vulnerable consumers, the challenges of digitalisation and decarbonisation, and the path to a just transition.

1. Defining Vulnerability in the Energy Market

1.1. Who is Vulnerable?

Vulnerability in the energy context is multi-dimensional and dynamic. Ofgem defines a vulnerable consumer as someone “who, due to their personal circumstances and characteristics, is especially susceptible to harm, particularly when a supplier is not acting with appropriate care.” Vulnerability can be:

Financial: Low income, fuel poverty, or debt.
Health-related: Physical or mental health conditions, disability, or age.
Situational: Life events such as bereavement, job loss, or relationship breakdown.
Digital: Lack of access to or confidence with digital services.

1.2. The Scale of the Challenge

Fuel Poverty: In 2022, around 13% of households in England were estimated to be in fuel poverty (BEIS: Fuel Poverty Statistics).
Prepayment Meters: Over 4 million households use prepayment meters, often associated with higher costs and greater risk of self-disconnection.
Digital Exclusion: As services move online, those without internet access or digital skills risk being left behind.

2. Policy and Regulatory Frameworks

2.1. Ofgem’s Consumer Vulnerability Strategy 2025

Ofgem’s Consumer Vulnerability Strategy 2025 sets out five key themes:

Improved Identification: Proactively identifying and supporting vulnerable consumers.
Fair Treatment: Ensuring all consumers are treated fairly, with tailored support.
Affordability: Addressing the root causes of affordability challenges.
Inclusive Innovation: Ensuring new products and services benefit all.
Collaborative Action: Working with government, industry, and consumer groups.

2.2. Statutory and Licence Obligations

Supply Licence Conditions: Suppliers must maintain a Priority Services Register (PSR), offer free services to eligible consumers, and avoid disconnecting vulnerable households.
Price Cap: The default tariff cap protects disengaged and vulnerable consumers from excessive prices (Ofgem: Price Cap).

2.3. Government Schemes

Warm Home Discount: Provides a £140 annual rebate to eligible low-income and vulnerable households.
Energy Company Obligation (ECO): Funds energy efficiency improvements for fuel-poor and vulnerable households.
Winter Fuel Payment and Cold Weather Payment: Targeted support for older and low-income consumers.

3. The Impact of the Energy Crisis

3.1. Price Shocks and Supplier Failures

The 2021–2022 energy crisis saw wholesale prices soar, leading to the collapse of over 25 suppliers. Vulnerable consumers were disproportionately affected:

Tariff Loss: Many lost fixed tariffs and were moved to higher-priced default tariffs.
Credit Balances: Uncertainty over the protection of credit balances and Warm Home Discount payments.
Disruption: Confusion and anxiety during supplier switches, especially for those with complex needs.

3.2. Case Study: Prepayment Meter Customers

Prepayment customers, often among the most vulnerable, faced particular challenges:

Self-Disconnection: Inability to top up meters led to periods without heat or power.
Access to Support: Not all suppliers had robust processes for identifying and supporting at-risk customers during the crisis.
Regulatory Response: Ofgem issued guidance to suppliers on supporting prepayment customers, including the use of discretionary credit and proactive outreach (Ofgem: Prepayment Meter Guidance).

4. Digitalisation and the Risk of Exclusion

4.1. The Digital Divide

The shift to digital services—smart meters, online billing, app-based support—offers many benefits but also risks excluding those without access or confidence.

Smart Meter Rollout: Some vulnerable consumers are less likely to have smart meters, missing out on benefits like accurate billing and access to time-of-use tariffs.
Online-Only Tariffs: The cheapest deals are often only available online, disadvantaging those without internet access.

4.2. Inclusive Innovation

Ofgem and BEIS are working to ensure that digital innovation is inclusive:

Accessible Design: Requiring suppliers and networks to design services that are accessible to all.
Alternative Channels: Ensuring support is available via phone, post, or in-person for those who need it.
Consumer Engagement: Funding digital literacy programmes and working with charities to reach at-risk groups.

5. Decarbonisation and Fairness

5.1. The “Just Transition”

A just transition means ensuring that the costs and benefits of decarbonisation are shared fairly. Key issues include:

Heat Decarbonisation: The move to heat pumps or hydrogen may require upfront investment that is unaffordable for many.
Electric Vehicles: Access to EVs and smart charging infrastructure is uneven, with rural and low-income households at risk of being left behind.
Energy Efficiency: Fuel-poor households often live in the least efficient homes, facing higher bills and greater health risks.

5.2. Policy Responses

Targeted Support: Expanding schemes like ECO and the Social Housing Decarbonisation Fund.
Tariff Innovation: Developing tariffs that reward flexibility without penalising those unable to shift demand.
Community Energy: Supporting local energy projects that deliver benefits to vulnerable groups.

6. Industry Initiatives and Best Practice

6.1. Priority Services Register (PSR)

All suppliers and networks maintain a PSR, offering free services such as accessible billing, meter reading, and priority support during outages. Ofgem monitors PSR performance and encourages proactive identification of eligible consumers.

6.2. Supplier and DNO Innovation

Inclusive Tariffs: Some suppliers offer “social tariffs” or targeted discounts for vulnerable customers.
Proactive Outreach: DNOs and suppliers are using data analytics to identify at-risk customers and offer tailored support.
Collaboration with Charities: Partnerships with organisations like Citizens Advice, Age UK, and National Energy Action (NEA) extend the reach of support.

6.3. Case Study: UK Power Networks’ Vulnerability Strategy

UK Power Networks has developed a comprehensive vulnerability strategy, including data sharing agreements with local authorities, targeted outreach, and a dedicated vulnerability team. The company’s approach has been recognised as best practice by Ofgem (UKPN: Vulnerability Strategy).

7. The Road Ahead: Challenges and Opportunities

7.1. Rising Costs and the Cost-of-Living Crisis

The ongoing cost-of-living crisis, exacerbated by high energy prices, means that vulnerability is likely to increase. Policymakers and industry must remain vigilant and responsive.

7.2. Data and Digitalisation

Better use of data can help identify and support vulnerable consumers, but must be balanced with privacy and consent.

7.3. Regulatory Evolution

Ofgem is reviewing the effectiveness of existing protections and considering new measures, such as mandatory social tariffs and enhanced supplier obligations.

7.4. Whole-System Fairness

Ensuring fairness across the whole system—generation, networks, supply, and demand—is essential for a just transition.

8. Lessons Learned

Vulnerability is Dynamic: Anyone can become vulnerable, and support must be flexible and responsive.
Collaboration is Essential: No single actor can address vulnerability alone; partnership across government, industry, and civil society is vital.
Innovation Must Be Inclusive: The benefits of digitalisation and decarbonisation must be accessible to all.

Conclusion

The energy transition is an opportunity to build a fairer, more inclusive system—but only if vulnerability and fairness are at the heart of policy, regulation, and innovation. The challenges are significant, but so too are the opportunities to deliver a just transition that leaves no one behind.
