What could the next energy price cap cost you?

Ofgem announces the January–March 2027 cap on or before 25 November 2026. Forecasts vary a lot, so pick a scenario and see what it could add to your month.

1 · Your energy bill

On a typical household bill
+£36a month

About £427 more a year. Your monthly bill would go from £144 to £179.

The £100 Budget payment, if you qualify (households in council tax bands A–D in England, paid January 2027), would cover roughly 2.8 months of this rise. It is a one-off, and your council contacts you directly. Nobody else should, so treat any text or email asking you to “claim” it as a scam. You can find your council at gov.uk.

So where does the extra £36 come from?

Rising bills squeeze the pound that was meant for something else. Golden Percentages builds a personal split of whatever is left each month. It’s free, takes about two minutes and needs no signup.

Estimates only, not a quote or financial advice. The current typical cap of £1,723 a year (Oct–Dec 2026) is from Ofgem. Forecasts are as of 4 November 2026 and will change when Ofgem announces the real cap. Your own bill depends on how much energy you use, your region, payment method and tariff. The Budget measures described are those reported after the 28 October 2026 Budget; some apply to England only, so check gov.uk for the details that apply to you.
