    Fixed Deals Return with Savings as Global Prices Surge

    UK households can now find fixed energy deals offering significant savings compared to the upcoming price cap, marking a positive shift for consumers. However, global energy prices, particularly for gas and oil, continue to climb, driven by geopolitical events and winter demand forecasts. This upward pressure on wholesale costs is expected to lead to further increases in the UK energy price cap into 2027.

    What the cap means for typical consumption

    Ofgem's published typical consumption benchmark and a lower-consumption household, side by side.

    Official current figure · Ofgem

    Ofgem's headline capped figure of £1,862 is calculated on Ofgem's cap benchmark household of 2,700 kWh of electricity and 11,500 kWh of gas at the capped rates below. On Ofgem's current Typical Domestic Consumption Values (2,500 kWh electricity / 9,500 kWh gas) the same capped rates come to about £1,664. The two figures differ only because they use different consumption bases, not different rates.

    The price cap limits unit rates and standing charges. It does not limit a household's total bill, which depends on actual energy use. £1,862 and £1,664 are illustrations only, not the maximum a household can be charged.

    Price-cap and tariff developments

    PowerGuardian analysis of the week's price and tariff signals.

    PowerGuardian analysis

    Despite the positive news of new competitive fixed deals, the broader outlook for energy prices remains challenging. Increases to the price cap are forecast for Q4 2026 and Q1 2027, driven by firming wholesale gas prices and anticipated winter demand. Households able to secure a fixed deal now could protect themselves from these upcoming increases, but those remaining on variable tariffs will see higher bills.
