Ofgem closes British Gas prepayment meter investigation with warning

Ofgem has closed its investigation into British Gas’s installation of prepayment meters under warrant, warning of ‘shortfalls’ in the company’s handling of vulnerable households. The decision, announced on 15 May 2026, marks the end of a probe that began after reports of forced installations during the 2022-2023 energy crisis.

Centrica, British Gas’s parent company, confirmed the closure in a statement, noting that the regulator had not imposed a fine. But the South Wales Argus reports that the watchdog warned of ‘shortfalls’ in the process, raising questions about whether the company had adequately protected vulnerable customers.

What the investigation found

Ofgem’s investigation focused on British Gas’s use of court warrants to force-install prepayment meters in homes where customers had fallen behind on bills. The regulator found that the company had not always checked whether residents were vulnerable, for example, elderly people, those with disabilities, or families with young children, before proceeding with installation.

The probe was launched in early 2023 after a series of media reports highlighted cases where bailiffs and engineers entered homes without proper safeguards. British Gas had already voluntarily paused warrant-based installations in February 2023, but Ofgem continued its investigation to assess systemic failures.

Now closed, the investigation has not resulted in a financial penalty. But the warning of ‘shortfalls’ is a significant rebuke. For homeowners, the key question is whether the same risks remain for other suppliers, and what protections exist for those on prepayment meters.

What it means for your bills and rights

Prepayment meters are typically used by households in debt or on low incomes. They often come with higher standing charges and unit rates than direct debit tariffs, adding roughly £100–£150 a year to a typical bill. For a 3-bed semi using 12,000 kWh of gas and 2,900 kWh of electricity, that could mean an extra £8–£12 per month.

But the bigger issue is consumer rights. Under current rules, suppliers can apply for a warrant to install a prepayment meter if a customer has missed payments and refused to engage. The warrant allows forced entry, but suppliers must first assess vulnerability. The British Gas case suggests those checks were not always rigorous.

For homeowners, this means: if you are struggling with energy debt, you have the right to request a repayment plan or a temporary suspension of warrant applications. Citizens Advice recommends contacting your supplier immediately if you are at risk of having a prepayment meter installed. You can also ask for a ‘vulnerability marker’ to be placed on your account if you or someone in your household has a health condition or disability.

Energy efficiency grants and prepayment meters

Prepayment meter customers are also less likely to access energy efficiency schemes such as the Boiler Upgrade Scheme or ECO4. The ECO4 programme, which funds insulation, boiler upgrades, and heat pumps for low-income households, often requires a stable energy supply. Prepayment meters can complicate eligibility because installers need access to the meter and the property.

The Home Upgrade Grant (HUG2) is another route for off-gas-grid homes, but again, prepayment meter status can slow down applications. Ofgem’s warning may push suppliers to improve their processes, but for now, homeowners on prepayment meters should check with their local authority or energy supplier about available support.

What this means for the wider market

The closure of this investigation comes amid broader scrutiny of energy supplier conduct. Ofgem has already fined other suppliers for similar breaches, including E.ON and Scottish Power. The fact that British Gas escaped a fine may reflect a change in regulatory approach, or simply that the evidence did not meet the threshold for a penalty.

But the warning is clear. Suppliers must ensure that vulnerable customers are not subjected to forced prepayment meter installations without proper checks. For homeowners, the message is: know your rights, and if you are at risk of debt, act early. The energy price cap remains in place, but it does not protect against warrant-based installations.

What this misses is the broader picture: the UK still has over 4 million prepayment meters in homes, many in fuel poverty. The government’s Energy Security Bill, currently in parliament, includes provisions to strengthen consumer protections, but it has not yet become law. Until then, homeowners must rely on supplier goodwill and regulatory warnings.

Next steps for homeowners

If you are on a prepayment meter or at risk of having one installed, here is what to do now:

• Contact your supplier immediately if you are struggling with debt. Ask for a repayment plan or a temporary payment holiday.
• Request a vulnerability marker if you or a household member has a health condition, disability, or is over 70.
• Check your eligibility for energy efficiency grants through the Energy Company Obligation (ECO4) or local authority schemes. Visit gov.uk/energy-grants for details.
• If you believe a supplier has installed a prepayment meter without proper checks, complain to Ofgem via its website or call 020 7901 7295.

The clock is ticking: Ofgem’s warning may lead to tighter rules, but for now, the onus is on homeowners to protect themselves. Act before the next cold snap.
