UK households face another increase in energy bills from 1 October as Ofgem’s latest price cap comes into force, adding pressure at a time when household energy debt has already reached record levels.
The regulator confirmed a 2% rise in the cap, lifting the average annual dual fuel bill to £1,755. While this increase may look modest compared with the huge surges of recent years, analysts warn that further policy costs and market volatility could see bills jump again in 2026.
Forecasts Point to Higher Bills Ahead
Cornwall Insight, one of the UK’s leading energy consultancies, forecast that the October–December rise could be reversed in early 2026, with a predicted £30 fall in average bills. However, the group also cautioned that additional costs linked to nuclear investment and renewable schemes could add at least £100 to bills from April.
Its projections suggest the energy price cap may climb to £1,855 by spring 2026. This reflects not only wholesale market risks but also the increasing burden of policy costs to fund renewables, nuclear projects, and efficiency schemes.
The government has already signalled that a £10 annual levy will be introduced to fund next-generation nuclear power stations, while consultations are ongoing about how to spread the costs of Britain’s transition to cleaner energy.
Record Energy Debt a Growing Problem
Ofgem data revealed that household energy debt hit £4.4 billion during the second quarter of 2025 — up £750 million on the same period a year earlier. More than one million households are behind on payments without a repayment plan in place.
Consumer groups have expressed alarm at the figures, warning that winter 2025 could push debt even higher if households are unable to reduce their bills or secure financial support.
Martin McCluskey, Minister for Energy Consumers, said: “We are taking urgent action to support families this winter, expanding the Warm Home Discount to more than six million households. But wholesale gas costs remain 75% above pre-invasion levels, which is why we must shift to clean, homegrown power to stabilise bills in the long term.”
Why Households Remain Exposed
The price cap affects around 34 million households on default or prepayment tariffs. A further 20 million on fixed-rate contracts are shielded until their terms end, but many will face higher prices in the months ahead.
Wholesale gas costs have remained stable in recent months, but households remain exposed because the cap also reflects standing charges and policy levies. This means bills stay elevated even without major wholesale shocks.
Shay Ramani, energy expert and founder of Free Price Compare, explained:
“Households often think the price cap gives them protection, but in reality it only sets a ceiling on default tariffs. Even with the cap, many families are overpaying because they have not compared tariffs recently. With suppliers now reintroducing competitive fixed deals, switching remains the single most effective way to take control of energy costs before winter.”
How Households Can Take Control
Industry experts highlight that reviewing tariffs is still one of the best ways to bring bills down. Many suppliers currently offer fixed tariffs below the October cap, with potential savings of more than £200 for the average household.
One of the most effective steps is to compare energy prices across different suppliers to secure a cheaper deal. For households that rely heavily on both gas and electricity, running a dual fuel energy comparison can identify bundled tariffs with lower standing charges and unit rates, making bills easier to manage.
Online comparison tools such as Free Price Compare provide postcode-based checks to find the cheapest deals in your area, ensuring households avoid being trapped on expensive standard variable tariffs.
Policy Costs and the Push to Net Zero
Another challenge facing households is the role of policy costs in bills. These charges fund renewable expansion, nuclear projects, and home insulation schemes — essential investments in the UK’s energy future but burdensome for consumers in the short term.
Shay Ramani added:
“There’s a real balance to be struck. Investment in clean energy is vital to end our dependence on volatile global gas markets, but those costs are already feeding into household bills. The government and Ofgem must ensure that vulnerable families are shielded from the brunt of these charges, otherwise we risk pushing more households into debt.”
Urgency Before Winter
With winter approaching, households are being urged to take action. Even modest savings can make a difference when combined with government support such as the Warm Home Discount and energy efficiency schemes.
Shay Ramani, energy expert at Free Price Compare, said:
“Many households don’t realise that fixed deals are once again appearing below the October price cap. By comparing and switching now, families could save hundreds of pounds over the course of a year. The savings are not just theoretical — we are seeing competitive fixed offers in the market today that undercut the capped rates by a wide margin. Acting before winter sets in gives households the best chance to lock in stability and avoid paying more in the months ahead.”
The combination of targeted government support, supplier discounts, and proactive tariff switching could be the difference between manageable bills and mounting arrears this winter.
Shay Ramani concluded:
“The reality is that debt is rising, policy costs are climbing, and the cap will not shield households forever. Families need to take action now — review your tariff, check eligibility for discounts, and don’t wait until January when deals may disappear. A few simple steps taken today can help avoid financial stress later in the winter.”
