UK Energy Price Update — 18 May 2026: Ofgem Tackles Prepayment Issues

Ofgem has secured a £20 million settlement from British Gas over unfair prepayment meter practices. This comes amid wider efforts to address energy debt, with proposals to write off £500 million in unpaid bills for vulnerable households.

Summary This week, Ofgem announced a £20 million settlement with British Gas after an investigation into unfair prepayment meter practices. This action highlights ongoing concerns about customer support, particularly for vulnerable households, while proposals are also being considered to write off £500 million in energy debt.

What this means in plain English Ofgem, the energy regulator, has stepped in to penalise British Gas for how it treated some customers with prepayment meters. Essentially, British Gas didn't follow the rules when dealing with vulnerable customers, leading to this significant payout. This money will go into a fund to help other energy customers.

This news comes alongside a broader discussion about the rising amount of unpaid energy bills across the UK. There's a suggestion from Ofgem to write off around £500 million of this debt, which would mean that households struggling to pay their bills would get some relief. However, the cost of this could potentially be spread across everyone else's bills, meaning other bill payers might see a small increase to cover it.

Other important developments include:

- Over £3.4 billion in benefits have been delivered to consumers through improvements in grid operation and making the energy market work better. - In Scotland, there are efforts to better manage energy demand, which could help lower long-term bills by increasing the use of clean energy generated in the UK. - Schemes like ECO4 Flex are helping more low-income households and those with health conditions get support for making their homes more energy efficient, such as installing insulation.

How this affects your household bill The news this week has a few direct and indirect impacts on your energy bills.

Firstly, for those on prepayment meters, especially those who might have been unfairly treated by British Gas, the settlement could indirectly lead to better practices from suppliers in the future. While the £20 million doesn't go directly to affected individuals, it signals that the regulator is serious about protecting vulnerable customers.

Secondly, the proposal to write off £500 million in energy debt is a double-edged sword. If implemented, it would ease the burden for those currently in debt, but it might mean a very small increase in standing charges or unit rates for all other customers to cover the cost. The exact impact per household is not yet clear, but it's likely to be a minor adjustment if it goes ahead.

Looking ahead, our forecasts for the coming months suggest:

- July-September 2026 (Q3): We expect the energy price cap to be around £1680 for a typical household, with the best fixed deals potentially around £1550. This reflects easing wholesale gas prices and lower summer demand. - October-December 2026 (Q4): Prices are likely to rise as winter approaches, with the cap potentially around £1790 and best deals at £1650. This is due to increased demand and slightly firmer wholesale gas prices.

Standing charges are expected to remain stable in the short term. Households on standard variable tariffs are most exposed to these price cap changes. Prepayment meter users will also see these changes reflected directly in their top-ups. Those with electric heating might feel the winter rises more keenly due to higher electricity consumption.
