The Uncomfortable Truth About UK Energy Costs in the Next 12 Months

22nd July 2026

Profits soaring, debts exploding, supply tightening — and millions cutting back on basic heat and hot water.

The UK is heading into one of the most punishing 12‑month periods for household energy costs in modern history. Politicians will talk about “support”, “relief”, and “stability”, but the data tells a different story — one that is far more brutal.

Energy companies are still making multi‑billion‑pound profits, much of which flows straight overseas to foreign shareholders. Two global wars are hammering supply chains. Wholesale gas markets remain tight. Oil shipping routes are disrupted. And household energy debt is rising at a pace that should alarm every policymaker in the country.

Millions of people are already cutting back on basic heating and hot water.
The next 12 months will be worse.

This is the uncomfortable truth — and it’s time to say it plainly.

The Data: UK Household Energy Debt Is Exploding
The numbers are not “concerning”. They are catastrophic.

£3.1 billion — total UK household energy debt (Ofgem, 2026)

3.7 million households in arrears on electricity or gas

1.2 million prepayment customers self‑disconnecting at least once a month

42% of low‑income households now rationing hot water

27% of households report cutting shower time or skipping showers entirely

18% regularly wash dishes in cold water

11% boil only enough water for one cup of tea or coffee

These are not fringe behaviours.
They are becoming normal.

And the next 12 months will not reverse this trend — because the pressures driving it are structural, global, and intensifying.

The Profit Problem: Money Leaving the UK
The UK’s energy system is almost entirely privatised. That means:

Profits go to shareholders

Many of those shareholders are foreign investors

Dividends leave the UK economy

Infrastructure investment depends on corporate priorities, not national strategy

In 2025–26:

BP reported $15.2 billion profit

Shell reported $19.4 billion

Centrica (British Gas) reported £2.7 billion

National Grid reported £4.2 billion

Meanwhile:

UK households accumulated £3.1 billion in energy debt

1 in 10 households turned off heating entirely last winter

1 in 5 households reduced hot water use to “minimum levels”

The contrast is obscene — and it is getting worse.

Two Wars, One Global Energy System
The UK does not control global energy markets. It is a price‑taker, not a price‑maker.

Ukraine war
Europe lost 40% of its gas supply from Russia

LNG imports surged, raising global prices

UK wholesale gas prices remain 2–3× higher than pre‑2021 averages

Middle East conflict
Oil shipping routes disrupted

Insurance costs up 30–50%

Global oil prices volatile and elevated

These pressures will continue throughout the next year.
There is no quick fix.

Gas and Oil Supply: Tight, Expensive, Uncertain
Global gas markets remain tight because:

Europe is still replacing Russian supply

Asian LNG demand is rising

Production growth is slow

Storage costs are high

Oil markets are constrained because:

OPEC+ continues to limit production

Shipping routes are disrupted

Refining capacity is stretched

The UK relies heavily on both.
When global supply tightens, UK bills rise — instantly.

The Human Reality: Cutting Back on Essentials
Across the UK, people are already making difficult choices:

Switching off hot water except for essential use

Shorter showers or fewer showers

Cold-water washing

Boiling only enough water for one cup

Heating only one room

Turning off heating entirely

These behaviours are becoming normal.
They will not disappear in the next 12 months.

The Next 12 Months: Why the Crisis Isn’t Going Away
Here is the hard truth:

1. Wholesale gas prices are forecast to remain 30–50% above pre‑crisis levels
Even if they fall slightly, they will not return to 2019 levels.

2. Oil markets will remain volatile
Shipping disruptions and OPEC+ cuts guarantee instability.

3. Energy companies will continue posting large profits
Privatisation ensures shareholder returns come first.

4. Household energy debt will continue rising
Ofgem expects arrears to increase by £400–600 million in the next year.

5. Millions will continue rationing heat and hot water
Because they have no choice.

The uncomfortable truth
The UK is entering a period where:

Energy companies will continue making huge profits

Much of those profits will continue flowing overseas

Global conflicts will continue disrupting supply

Oil and gas markets will remain tight

Household energy debt will continue rising

People will continue cutting back on basic heating and hot water

There is no policy currently in place that changes this trajectory in the next 12 months.

This is the uncomfortable truth — and it needs to be said plainly.
