Typical annual energy bills could rocket to £6,400 by 2036 if recent price rises keep biting at the same pace, according to new analysis.

The warning matters for ordinary households because energy is one of the core costs families cannot simply cut out. Keeping the lights on, heating the home and cooking meals could become an even more alarming annual expense if recent increases were to continue compounding.

The figure is not an official forecast and it does not mean every home would pay the same amount. It is an annualised typical bill figure based on domestic energy price cap style figures for typical dual-fuel use in England, Scotland and Wales. Northern Ireland has a separate energy market, so the figure should not be read as a Northern Ireland bill forecast.

The visible workings are stark:

• 2020: £1,042
• 2026: £1,862

That means the typical annual bill rose by an average of 13.1% a year between 2020 and 2026.

If typical annual energy bill prices keep rising at the average yearly rise of the last 6 years, 13.1% a year, it could cost £6,400 by 2036.

For consumers, the analysis is best treated as a stress-test of what prolonged bill inflation could mean for household budgets, rather than a prediction of what any individual home will pay. Actual bills depend on usage, tariff, standing charges, meter type, home efficiency and future regulatory decisions.

Households worried about their energy costs should check their current tariff and usage, submit regular meter readings where relevant, review any available supplier support, and seek help early if they are falling behind on bills.

Forecasting analysts at Predictionist, which tracks consumer-impact price trends, ran the numbers to show what recent bill growth would look like if it continued for another decade.

A spokesperson for Predictionist said: "This is a warning scenario, not a prediction that every household will face the same bill. The point is to show how quickly a familiar annual cost can become alarming when percentage rises compound over time.

"Energy bills are especially painful because households cannot simply opt out of heating, lighting and cooking. Even a smaller rise can force difficult choices when budgets are already stretched."

The analysis used 2020 as the starting point and 2026 as the anchor year, then applied the stated average yearly rise across the six-year window to the period through 2036.
