£20 Million for Breaking Into Homes: Inside the British Gas Prepayment Meter Scandal

In January 2023, an undercover reporter working for The Times walked into the offices of Arvato Financial Solutions, a third-party debt collection firm contracted by British Gas. What the reporter documented over subsequent weeks — debt agents breaking into the homes of people with severe mental illness, physical disabilities, and young children to force-fit prepayment energy meters — became one of the most politically explosive stories of Britain's energy crisis [1].

More than two years later, British Gas has agreed to pay £20 million into Ofgem's Voluntary Redress Fund and write off up to £70 million in vulnerable customers' energy debt [2]. The settlement covers misconduct stretching from February 2018 to February 2023 — a period far longer than initially understood when the scandal first broke.

The question now is whether this amounts to accountability or simply the cost of doing business for a company whose parent, Centrica, posted £3.3 billion in operating profit in 2022 alone [3].

What Happened: The Mechanics of Force-Fitting

British Gas used a legal mechanism known as a right-of-entry warrant, obtained through magistrates' courts, to gain access to customers' homes and install prepayment meters. Under Ofgem's licence conditions, suppliers can apply for such warrants only after exhausting all reasonable attempts to negotiate payment, and only as a last resort before disconnecting a customer's supply [4].

In practice, this process was outsourced to Arvato Financial Solutions. Between January 2019 and December 2022, Arvato was granted almost 300,000 right-of-entry warrants on behalf of energy suppliers across the UK [5]. British Gas's agents reportedly accounted for roughly a third of all warrant applications to force-fit prepayment meters during this period [6].

The Times investigation revealed a critical structural problem: Arvato's teams were earning bonuses for each prepayment meter installed [7]. When an agent arrived at a property and found signs of vulnerability — a disabled resident, young children, mental health conditions documented in job notes — the financial incentive was to proceed with installation rather than pause and investigate further. According to job notes seen by The Times, customers who had meters forced upon them included "a woman in her fifties described as 'severe mental health bipolar', a woman who 'suffers with mobility problems and is partially sighted' and a mother whose 'daughter is disabled and has a hoist and an electric wheelchair'" [1].

The Scale of Harm

Ofgem's Market Compliance Review required suppliers to examine more than 150,000 cases of involuntary prepayment meter installation, encompassing both physical meters installed under warrant and smart meters remotely switched to prepayment mode [8]. Some 40,000 customers who had a prepayment meter installed without their permission between 2022 and 2023 were identified as eligible for compensation across the industry, with British Gas being the largest single contributor [5].

The settlement now extends redress to customers affected between 2018 and 2021 — a group that had not previously received compensation [2]. Ofgem found that British Gas "failed to meet the standards required" of a supplier and breached licence conditions "designed to protect customers in vulnerable situations" [9].

Prepayment meter customers in the UK grew steadily during this period, reaching an estimated 4.5 million by 2023. These customers — disproportionately low-income, elderly, or living with disabilities — were already among the most financially strained energy consumers in the country.

Vulnerable Customers: Who Was Targeted

Ofgem's licence conditions establish clear categories of customers who should receive enhanced protection. The regulator maintains a Priority Services Register that flags households with specific vulnerabilities. British Gas's obligations included identifying and protecting:

• People over 85 and those of pensionable age
• Residents with severe health conditions, including terminal illness or medical dependency on a warm home (conditions such as emphysema, chronic bronchitis, and sickle cell disease)
• People with mental health conditions or cognitive impairments
• Households with children under six (protected from disconnection year-round) and children under 16 (protected during winter months) [10]

The evidence gathered by The Times and subsequently by Ofgem showed that British Gas agents entered homes matching multiple vulnerability categories. A single father with three young children and a mother with a four-week-old baby were among those documented [1]. Ofgem confirmed that British Gas "knew about these failings as far back as 2018, was warned again in 2021, and still did not take adequate action" [9].

For people whose experience would be "severely traumatic due to an existing vulnerability relating to mental or psychological state," Ofgem has since banned involuntary installations entirely [8].

The £20 Million Question: Fine or Fee?

The £20 million payment must be set against Centrica's financial performance during the years the misconduct occurred.

Centrica's group operating profit surged from £410 million in 2020 to £3.3 billion in 2022, before settling at £2.8 billion in 2023 and £1.6 billion in 2024 [3][11]. British Gas's own profits rose tenfold, from £72 million in 2022 to £751 million in 2023, as energy crisis costs were recovered from customers [12].

The £20 million redress payment represents approximately 0.6% of Centrica's 2022 operating profit, or roughly 2.7% of British Gas's 2023 profit. Even including the £70 million debt write-off (which reflects money that might never have been collected from customers in severe financial distress), the total exposure of £90 million amounts to around 2.7% of Centrica's 2022 profit.

Sharon Graham, general secretary of Unite, said British Gas's parent company had been "coining it in from energy bills while sending bailiffs to prey on vulnerable consumers" [13]. Critics have argued the settlement amounts to a rounding error rather than a deterrent. No independent calculation has been published quantifying the total financial benefit British Gas derived from moving customers onto prepayment meters, though prepayment tariffs have historically carried higher unit rates than direct debit plans [14].

Since 2024, Ofgem has adjusted standing charges so that prepayment customers pay slightly less overall than those on standard variable tariffs, but unit rates for prepayment meters remain typically higher than fixed credit tariffs [14]. During the years of misconduct, before this adjustment, customers forced onto prepayment meters were paying a measurable premium — effectively penalised for being in debt.

What Ofgem Knew — and When It Acted

The timeline raises difficult questions about regulatory oversight. Energy companies received more than 700,000 complaints about their treatment of indebted customers over the five years preceding the scandal's exposure, with 40,000 complaints in the final year alone relating specifically to forced fitting or disconnection via prepayment meters [15].

OpenDemocracy reported that Ofgem "was only forced into action when an undercover Times investigation" exposed the practices [15]. The regulator launched its formal investigation into British Gas on 21 February 2023 — weeks after The Times published its findings and days after Centrica suspended all warrant activity [16]. This sequence — media exposure first, regulatory action second — has fuelled criticism that Ofgem was reactive rather than proactive despite years of accumulating complaint data.

Ofgem's own enforcement guidelines state that within 20 working days of receiving a complaint, the regulator should acknowledge receipt and, in 90% of cases, indicate whether it intends to investigate [17]. The gap between the volume of complaints received and the absence of enforcement action before 2023 has not been fully explained.

The Ofgem Review, published in 2026, examined broader questions about the regulator's effectiveness, though the full implications of that report for prepayment meter enforcement remain to be seen [18].

The Warrant Process: Judicial Oversight Failures

The warrant application process itself came under scrutiny. Magistrates' courts were approving applications in bulk, with limited opportunity to assess individual circumstances. Following the scandal, the Senior Presiding Judge and Chief Magistrate issued directions reforming the warrant process for prepayment meters [19].

British Gas permanently ceased all warrant activity with Arvato and brought the process in-house [20]. As of the settlement date, British Gas has not restarted warrant-based prepayment meter installations [9].

The judiciary's willingness to rubber-stamp large numbers of warrant applications without meaningful scrutiny of vulnerability data represents a systemic failure that extended beyond any single energy company. The warrant process, designed as a safeguard, had become a conveyor belt.

International Comparison: Is This a UK Problem?

The UK's regulatory framework for energy disconnection differs from its European counterparts in ways that may have enabled this outcome.

France has maintained a ban on electricity disconnection during winter months since 2013. Between 1 November and 31 March, energy providers cannot cut off consumers, and EDF has adopted a voluntary policy not to disconnect customers at any time of year, instead guaranteeing a minimum level of service [21].

Germany's energy law does not formally define "vulnerable customers," but it restricts disconnection to cases where the debt exceeds two monthly bills and prohibits it where there is "danger for the life or health of the customer or household members" [22].

At the EU level, revised electricity market directives agreed in late 2023 require member states to ensure that vulnerable and energy-poor customers are "fully protected from electricity disconnections" by 2026 — either through outright bans or equivalent protective measures [23].

The UK, post-Brexit, is not bound by these EU requirements. Its framework has historically relied on supplier licence conditions enforced by Ofgem — a model that, in the British Gas case, failed to prevent years of documented harm despite existing rules that nominally protected vulnerable customers. Whether this represents a structural weakness in the UK's approach or a company-specific failure at British Gas is debated. The fact that Ofgem's market-wide review identified problems across multiple suppliers, with a further £18.6 million in compensation and debt write-offs committed by other energy companies, suggests the problem extended beyond a single firm [24].

What Changes: The Settlement Conditions

The settlement imposes several concrete requirements on British Gas:

• A review of customer records from 2018 to 2023, with redress and compensation for affected households [2]
• Debt write-off of up to £70 million for vulnerable customers [2]
• Independent audits to identify wrongfully installed prepayment meters, with suppliers required to reinstate non-prepayment methods and offer compensation where installations were improper [8]
• Regular monitoring data submitted to Ofgem to flag concerning trends in involuntary prepayment meter practices [8]
• Strengthened internal governance, acknowledged by Ofgem, including bringing warrant work in-house and ending reliance on third-party debt collectors for forced installations [20]

Across the industry, Ofgem now requires suppliers to make at least 10 attempts to contact a customer and carry out a welfare visit before any involuntary prepayment meter installation [8]. Suppliers must gain Ofgem's explicit permission before restarting involuntary installations, and the regulator conducts checks to verify compliance with restart conditions [8].

The independent verification mechanism relies primarily on supplier-commissioned audits reviewed by Ofgem, supplemented by the regulator's own compliance monitoring. Whether this is sufficient given Ofgem's track record of detecting problems only after media exposure remains an open question.

The UK Consumer Price Index continued to climb through the period covered by the scandal and beyond, rising 3.4% year-over-year as of March 2025 — a reminder that the cost-of-living pressures driving customers into energy debt have not abated.

What Remains Unanswered

Several questions remain without clear public answers. No comprehensive demographic breakdown has been published showing exactly how many of the affected households included disabled residents, elderly customers, or families with children — data that would reveal the full scope of vulnerability failures. The total additional revenue British Gas collected from customers forced onto higher prepayment tariffs has not been independently calculated. And the question of individual accountability — whether any executives or managers face personal consequences — has not been addressed by the settlement.

British Gas, for its part, has acknowledged failings and pointed to its strengthened governance and decision not to restart warrant-based installations. Centrica CEO Chris O'Shea previously pledged to donate 10% of British Gas Energy profits to help customers [25].

The £20 million settlement closes a regulatory investigation. Whether it closes the chapter on how Britain's energy market treats its most vulnerable customers is a different matter entirely.
