What is the energy price cap and does it cap my bill?

Question

No — it caps the unit rate and daily standing charge a supplier can charge on a standard variable tariff, not your total bill. A household using more energy pays more. Ofgem sets it quarterly, and the widely quoted 'typical annual bill' is an illustration based on assumed usage, not a maximum. Ofgem, the energy regulator, sets a maximum unit rate for each kilowatt hour of gas and electricity and a maximum daily standing charge, for customers on standard variable tariffs in England, Scotland and Wales. It is reset every three months. The 'typical annual bill' figure that dominates the coverage is derived from an assumed level of consumption for a medium household. It is a comparison tool, not a cap. If you use twice that amount, you pay roughly twice that amount. Standing charges are the part people find hardest to accept: a fixed daily amount payable whether you use any energy or not, covering network costs, meter provision and the socialised cost of supplier failures. They have risen substantially and fall hardest on low-usage households. Ofgem has consulted repeatedly on reform, including low or zero standing charge tariff options. The cap does not apply to fixed tariffs. Since fixed deals returned after the 2022 crisis, some have sat below the cap — a fix is essentially insurance against increases, paid for by giving up the benefit of decreases. Northern Ireland has a separate energy market with its own regulator, the Utility Regulator, and is not covered by the Ofgem cap. Prepayment meter customers were historically charged more than direct debit customers; that differential has been addressed by policy changes, and prepayment rates are now aligned more closely with direct debit.
