Ovo fined £10.4m for failing vulnerable customers

The £10.4m penalty on Ovo Energy is not a rounding error. It is the price of failing to protect some of the UK’s most exposed households, those who rely on the Priority Services Register for free gas checks, meter readings, or emergency credit during a blackout. Ofgem’s investigation found that Ovo did not properly identify vulnerable customers, did not keep adequate records, and in some cases left people without the support they were legally entitled to receive.

As reported by MSN, the fine covers compensation to affected customers and a payment to Ofgem’s redress fund. But for the typical homeowner reading this, the question is less about Ovo’s corporate governance and more about what happens when your energy supplier drops the ball on vulnerable care, and whether you are at risk.

Who qualifies, and who doesn’t

The Priority Services Register is meant for households with someone of pensionable age, disabled, visually or hearing impaired, or with a long-term medical condition that makes heating essential. Yet Ofgem’s probe found Ovo did not consistently flag these customers when they joined, nor did it update records when circumstances changed. That is not a technical glitch. It is a systems failure that leaves people without priority reconnection after a power cut, without free gas safety checks, and without the annual meter reading that many vulnerable households rely on.

For homeowners upgrading their property, this matters because the same data gaps can affect your ability to claim energy efficiency grants. The Great British Insulation Scheme, for instance, requires proof of household income or receipt of certain benefits. If your supplier cannot keep basic records, the risk is that your application stalls, or you miss out entirely.

What it costs a typical 3-bed semi

On the surface, a £10.4m fine does not directly change your bill. Ovo’s 4.5 million customers will not see a credit line. But the cost of compliance, and the reputational damage, will be recovered through higher operating costs. Ofgem’s own modelling suggests that enforcement fines are ultimately passed to billpayers over time, though the regulator insists this is a deterrent, not a tax.

The catch is that vulnerable households already pay more per kWh than the average consumer. Those on prepayment meters, often the most financially exposed, face higher standing charges. If a supplier fails to identify them, they miss out on the Warm Home Discount, worth £150 this winter, and the priority reconnection that could prevent a £200 emergency call-out fee.

What this means for your EPC and upgrades

For Axiom readers, the practical takeaway is about use. When you switch suppliers, and you should switch at least once a year, ask whether they maintain an accurate Priority Services Register. Also ask how they handle vulnerable customers during a boiler breakdown or power cut. A supplier that scores poorly on these questions is likely to be the same one that drags its feet on smart meter installation or delays your ECO4 grant application.

Ofgem has made clear it will continue to investigate other suppliers. E.on, British Gas, and Scottish Power have all faced similar probes in the past three years. The regulator’s enforcement budget has increased 40% since 2022, and it now employs dedicated teams for vulnerable customer compliance. That is a shift worth watching.

What you should do now: Check if you or anyone in your household is on the Priority Services Register. If not, contact your supplier directly, they are legally obliged to add you. If you already are, ask for written confirmation of the services you are entitled to. The deadline for the Warm Home Discount application is 28 February 2025 for most regions. Do not assume your supplier has your back.
