    • Wholesale gas drives ~70% of the cap movement
    • Cap is a limit, not a target — fixed deals often beat it
    • Switching can save £200–£500/year vs the cap

    What this means for your household bill

    The price cap sets the maximum unit rate suppliers can charge you on a standard variable tariff. If the cap rises by £100, a typical home pays roughly £8.30 more per month.

    • On a standard variable tariff? You'll feel every cap change directly.
    • On a fixed deal? You're protected until your contract ends.
    • On prepayment? The cap applies but standing charges hit hardest.

    Don't assume the cap is the cheapest deal

    Most fixed tariffs available today beat the current cap by £150–£400/year. Always check.
