On October 16, 2026, Britain’s energy regulator, Ofgem, launched a public consultation regarding the activation of the Market Stabilisation Charge (MSC). This financial mechanism is designed to protect energy suppliers from extreme wholesale price volatility, particularly risks stemming from ongoing conflicts in the Middle East.
How the Market Stabilisation Charge Works
The MSC aims to mitigate the financial risks suppliers face when “hedging” energy. To provide stable prices for customers on default tariffs, providers typically buy gas and electricity in advance. However, if wholesale market prices suddenly drop, competitors can enter the market with much cheaper deals, drawing customers away from established suppliers who are locked into higher-priced contracts.
Under the proposed rules, the charge would be triggered if wholesale rates fall by more than 10%. If activated, any supplier gaining a customer on a cheaper tariff would be required to pay 85% of the wholesale price difference back to the customer’s former supplier. Ofgem noted that activating this mechanism does not automatically raise household bills; payments only occur during significant downward market shifts.
Preventing Supplier Failures and Market Disruption
Ofgem previously used the MSC between April 2022 and March 2024 to manage the energy shocks caused by Russia’s invasion of Ukraine. During that crisis, more than 30 retail suppliers went bankrupt. These failures caused massive market disruption and shifted substantial rescue costs onto consumers through the Supplier of Last Resort framework.
“We’re preparing for what is likely to be a difficult winter for many households,” said Neil Kenward, interim director general of markets at Ofgem. “While the energy market is stronger than it was during the energy crisis, volatility remains and the market stabilisation charge helps to protect consumers from that volatility. In volatile market conditions, it’s important that suppliers can continue to secure the energy their customers need without taking unsustainable risks.”
Competition and Consumer Concerns
The consultation has reignited debates over whether market stability should come at the expense of competitive pricing. Consumer advocate Martin Lewis, founder of MoneySavingExpert, criticized the proposal, arguing that the charge effectively penalizes consumers who switch providers to find lower bills.
Lewis highlighted that requiring incoming suppliers to pay compensation prevents them from passing the full benefits of wholesale market savings on to households. He also questioned the need to revive the measure, noting that major suppliers currently hold much stronger balance sheets than they did during the 2022 market collapse.
Energy Price Cap and Winter Outlook
The regulatory review arrives as domestic energy costs remain high. For the fourth quarter of 2026 (October to December), Ofgem’s energy price cap is £1,723 annually for a typical dual-fuel household, an increase from the £1,663 recorded in the third quarter.
Energy consultancy Cornwall Insight forecasts that the price cap could rise further in January 2027 to approximately £1,872 per year due to broader wholesale trends. Ofgem is accepting industry and public feedback on the MSC’s operational rules, trigger thresholds, and deactivation procedures until October 29, 2026.
