Ovo’s £11.5m penalty reveals the cost of failing vulnerable households

The £11.5m penalty imposed on Ovo Energy is a fine and also a signal. Ofgem found the supplier failed to properly identify and support vulnerable customers during the worst energy crisis in a generation. For UK homeowners, this shows the system meant to protect them has gaps, and that knowing your rights can save more than money.

As reported by Consumer Voice, the regulator’s investigation uncovered that Ovo failed to proactively identify customers in vulnerable circumstances, delayed responses to those in debt, and did not consistently record or act on medical needs. The fine, one of the largest ever for such failings, covers failings between 2020 and 2023.

What the penalty means for your household

The £11.5m will go to Ofgem’s voluntary redress fund, not to individual customers. But the ruling forces every supplier to review how they treat vulnerable households. If you are on a prepayment meter, have a health condition, or are over state pension age, you should be on the Priority Services Register (PSR). This entitles you to free services: priority reconnection after a power cut, advance warning of planned outages, and help managing your account. Ofgem estimates one in five eligible households is not registered.

EPC upgrades and the vulnerability link

There is a direct connection between energy efficiency and vulnerability. Homes with an EPC rating below C cost more to heat, often £300–£500 a year more than an A-rated home. For a household already struggling with bills, that extra cost can tip them into debt. The Great British Insulation Scheme and the Energy Company Obligation (ECO4) provide free or subsidised insulation and heating upgrades to low-income households. But to access them, you must be on certain benefits or referred by your supplier. Ovo’s failings suggest that even when customers needed help, the system did not catch them.

What you can do now

First, check if you or anyone in your home is eligible for the PSR. You can register through your supplier’s website or by calling them. Second, if you are behind on bills, your supplier must offer a payment plan that is affordable, they cannot force a prepayment meter installation if you have a health condition or are over 85. Third, if you feel your supplier has treated you unfairly, complain to the Energy Ombudsman. The Ombudsman can order compensation of up to £10,000 per complaint.

Ofgem’s action against Ovo sets a precedent. But the real change will come when every supplier, and every household, treats vulnerability as a core part of energy service, not an afterthought. Check your PSR status today. If you are not on it, you are missing out on protections that could matter this winter.
