Martin Lewis: 'Ofgem's plans to protect providers' profits from price swings will cost consumers'

Ofgem is considering changes designed to stop sudden wholesale energy-price movements from destabilising suppliers. The concern is that a supplier may promise a cheap tariff, then face much higher costs when it buys gas or electricity later. If several firms fail, customers and the wider market face disruption. The proposals therefore aim to make suppliers more financially resilient.

One reported mechanism would make a supplier pay a rival when it attracts that rival's customer with a cheaper deal. Other possible protections include requiring firms to manage wholesale-price exposure more carefully or hold stronger financial reserves. These measures would reduce the danger of a supplier being unable to buy energy at the price it promised.

The supplied headlines do not give a final Ofgem policy or implementation date. They do show the central trade-off: protecting suppliers could make tariffs, switching, or both more expensive. Martin Lewis warned that protecting providers' profits from price swings could ultimately cost consumers.

Ofgem is the Office of Gas and Electricity Markets, the regulator for Great Britain's energy markets. It oversees the companies that supply gas and electricity and sets rules intended to support competition, reliability, and customer protection. Its decisions affect how suppliers price tariffs, manage risks, and treat households when firms fail.

In this story, Ofgem is examining whether suppliers need more protection from sudden wholesale-price movements. It could require firms to prepare better for price changes or create rules requiring payments between companies when customers switch. Those rules would change how suppliers compete and how much risk sits with each business.

Ofgem must balance two goals. Customers need competitive, affordable deals and freedom to switch. Suppliers also need enough financial strength to survive sharp cost increases. The supplied headlines show the regulator is considering a compromise, but they do not state the final rules, timetable, or exact powers being adopted.

A charge linked to switching would make the advertised price of a cheaper tariff less important. Households would need to subtract the switching cost from their expected saving. If the fee is large, or the saving lasts only briefly, moving supplier may no longer be worthwhile. The charge could therefore weaken competition between energy companies.

For example, a household might find a tariff that appears to save money each month. If switching triggers a payment, the household may stay with its current supplier instead. The proposed mechanism is intended to compensate suppliers for risks created when customers leave, or when firms offer deals that later become expensive to honour. It shifts part of that risk into the switching decision.

Martin Lewis described a plan to introduce switching-related charges as not good for consumers. The supplied headlines do not state the proposed charge, who would pay it, or whether it would become policy. Its likely effect would depend on those details and on the size of the saving.

The figures requested are not included in the supplied source text. The material consists of headlines and a short description of Ofgem's proposed response. It refers to sudden wholesale-price swings and the UK's recent energy-price crisis, but gives no percentage, cash amount, date range, or count of failed suppliers.

That missing information matters because the scale of the crisis explains why Ofgem is considering intervention. A larger price jump creates more pressure on suppliers that have promised fixed or discounted tariffs. A higher number of failures would also make the case for stronger financial safeguards more urgent. Without figures, however, the size of that pressure cannot be calculated from this source.

The safest answer based on the supplied text is therefore that both numbers are unspecified. A full version of the article, or a named dataset from the crisis, would be needed to answer accurately. The headlines alone cannot support a precise rise or failure count.

Energy suppliers buy power and gas in a wholesale market, then sell it to households through tariffs. A sudden wholesale-price increase raises the supplier's costs. Customers on fixed or discounted deals may still pay the old price, so the supplier cannot immediately recover the extra money. The gap reduces profit and can turn into a loss.

For example, a company might offer a cheap fixed tariff expecting wholesale prices to remain manageable. If prices jump before the company has bought enough energy, it must purchase the remaining supply at the higher rate. It may lack the cash or reserves to cover that difference. Repeated losses can threaten the company's ability to trade.

That risk is the reason Ofgem is considering protections against wholesale-price swings. The supplied headlines connect the issue to suppliers' possible collapse. They also highlight the difficult trade-off: measures that make firms safer may transfer some costs or restrictions to households.

When an energy supplier collapses, customers are generally protected from an immediate loss of supply. Ofgem can appoint a replacement supplier under its Supplier of Last Resort process. Customer credit balances are also protected under established arrangements, although the recovery process can take time. These safeguards prevent households from being left without essential energy.

The replacement supplier takes over the accounts and continues supplying the homes. The failed company's unpaid costs and protected credit balances create a funding gap. Ofgem allows the new supplier to recover eligible costs through the market. In some cases, industry-wide arrangements spread the burden across suppliers rather than leaving it with one company.

The ultimate cost can therefore reach consumers through industry charges or higher bills. The supplied headlines frame this as an important background to Ofgem's plans. They suggest that preventing supplier failures may protect customers from those wider costs, but may itself make energy deals more expensive.

Household energy prices are built from several components. Wholesale gas and electricity costs are central, but suppliers also pay for networks, operating systems, customer service, policy obligations, and taxes. Suppliers set tariffs around those costs and their expectations about future wholesale prices. Fixed deals protect customers from some movements, but leave the supplier exposed if its forecasts are wrong.

Suppose a supplier promises a low fixed tariff before wholesale prices rise. It may need to buy replacement energy at a much higher price. A rule requiring more hedging, capital, or payments to cover switching risk could reduce the chance of collapse. But those protections are not cost-free. Suppliers may include them in tariffs or reduce discounts.

The result is a transfer of risk rather than its disappearance. Customers might face higher standard prices or less attractive switching offers, while suppliers become safer. The supplied headlines present this as the central dispute between market stability and consumer affordability.
