British Gas will pay £20 million to settle a regulator enforcement action over forced installation of prepayment meters on vulnerable customers. Ofgem, the UK energy regulator, determined that the supplier breached licence conditions designed to protect people in precarious financial situations.

The scandal centered on British Gas installing prepayment meters without proper consent or consideration for customer vulnerability. Prepayment meters require customers to load credit in advance, often at higher rates than standard billing. For vulnerable households already struggling with energy costs, this switch compounds financial hardship.

Ofgem's investigation found British Gas systematically failed to follow protections mandated in its operating licence. The regulator requires energy suppliers to treat vulnerable customers with particular care before forcing meter upgrades, especially when debt collection is involved. British Gas ignored these guardrails.

The £20 million penalty ranks among the largest Ofgem has levied against a single supplier. It underscores the regulator's increasingly aggressive stance toward energy companies that exploit vulnerable populations. Previous enforcement actions targeted similar meter-fitting abuses across the sector, but the scale here signals this remains a persistent industry problem.

The fine arrives as British Gas parent company Centrica faces mounting pressure over energy pricing and customer service failures. The settlement includes commitments from British Gas to review affected customers and provide appropriate remedies. The supplier must also improve compliance monitoring to prevent future breaches.

Energy regulator enforcement has intensified across the UK as households struggle with elevated bills. Ofgem's action demonstrates it will pursue suppliers who weaponize billing systems against vulnerable populations. For British Gas, the penalty compounds reputational damage from earlier scandals involving engineer conduct and billing disputes.
