8th October 2026
There is something increasingly strange about Britain's energy price cap.
Every few months the announcement arrives telling households what the new cap will be. But for millions of people the word "cap" must sound increasingly meaningless.
The latest cap rose by 4% from 1 October, taking the figure for a typical dual-fuel household paying by direct debit from £1,663 to £1,723 a year. That is another £60 a year, or £5 a month, if the new level were maintained for a full year.
And there is already a warning that the January figure could be considerably higher.
The House of Commons Library says the October cap leaves typical household bills 58% above their winter 2021/22 level. It also says current forecasts suggest another substantial increase could follow in January, although forecasts can change.
So perhaps it is time to ask a slightly uncomfortable question.
Is the energy price cap still the right way to protect households, or should government concentrate less on capping energy prices and more on reducing the bills people actually have to pay?
What does the price cap actually cap?
The first problem is the name.
The Ofgem price cap does not cap your annual energy bill at £1,723.
It caps the maximum unit rates and standing charges that suppliers can charge customers on standard variable tariffs.
Use more energy and your bill can be higher. Use less and it can be lower.
Ofgem currently caps average electricity at 26.32p per kWh and gas at 7.97p per kWh for direct-debit customers, alongside daily standing charges.
The cap is reviewed every three months.
That makes sense from a regulatory point of view. If the wholesale cost of supplying energy rises dramatically, suppliers cannot simply be expected to absorb the entire increase indefinitely.
But it also means that when wholesale energy becomes more expensive, the cap rises with it.
The cap therefore protects consumers from suppliers charging more than the regulated maximum, but it does not protect them from the underlying cost of energy.
That is a very different thing.
The cap has still done an important job
It would be wrong to suggest that the price cap is useless.
It protects around 22 million households on default tariffs by limiting what suppliers can charge.
Without regulation, customers who remain on standard tariffs could potentially be exposed to much higher charges.
And during the 2022 energy crisis, government intervention went considerably further than the normal price cap. The Energy Price Guarantee prevented household bills from rising even further when wholesale prices exploded.
So the argument isn't necessarily that Britain should simply abolish regulation and leave households at the mercy of the market.
The more interesting question is whether the price cap should remain the centrepiece of energy affordability policy.
A cap that keeps rising doesn't feel much like protection
Consider what has happened.
The energy crisis pushed prices dramatically higher.
Prices subsequently fell from their peaks, but household bills did not return to their old levels.
The House of Commons Library says the October 2026 cap leaves typical bills 58% above winter 2021/22 levels.
That is the problem politicians face.
A household doesn't experience the energy market as a wholesale price chart.
It experiences it as a direct debit leaving the bank account.
A pensioner doesn't necessarily care whether the increase is caused by wholesale gas, network charges, policy costs or supplier operating costs. The important question is:
"Can I afford the bill?"
Perhaps the focus should move from prices to bills
There are several alternatives that could be considered alongside, or eventually instead of, relying so heavily on the price cap.
One is a proper social tariff.
Rather than trying to keep energy artificially cheaper for everybody, government could provide additional help to households least able to afford it.
That could include households on low incomes, some pensioners and people with particular energy needs.
Another option would be to tackle standing charges.
From October, the average daily standing charge for electricity and gas combined is about 84.5p. That is roughly £309 a year before a single unit of energy is consumed.
For households with low consumption, standing charges can represent a surprisingly large proportion of the bill.
That raises an interesting question.
Should some of the fixed costs currently recovered through energy bills instead be funded through general taxation?
Then there is insulation
This may be the least exciting answer but potentially the most important.
If a house needs less energy to remain warm, it is less exposed to high energy prices.
The House of Commons Library says that, given the limited prospect of large reductions in energy prices, improving the energy efficiency of properties is one of the ways households can achieve substantial and lasting reductions in bills while still adequately heating their homes.
That suggests a different philosophy.
Instead of repeatedly helping people pay high energy bills, government could put much more emphasis on helping households need less energy in the first place.
Better insulation, draught-proofing, heating controls and more efficient heating systems can continue saving money after a particular government scheme has ended.
Government has already started moving some costs
There has already been an example of using taxation rather than simply relying on the price cap.
From 1 October, the government removed VAT from household electricity for six months. It says this will save the average household around £45 a year. It has also removed £150 of costs from bills earlier in 2026. Around six million households are eligible for a further £150 through the Warm Home Discount this winter.
Those measures show that there are alternatives to simply waiting for Ofgem's next announcement.
But they also illustrate the difficulty.
Government can reduce a household's bill, but ultimately the money has to come from somewhere.
If it is funded from taxation, taxpayers pay.
If it is loaded onto other energy customers, other bill payers pay.
If it is borrowed, future taxpayers pay.
There is no magic source of free energy.
And Britain's electricity prices raise another question
There is a particularly awkward issue here.
The UK has relatively low gas prices compared with many European countries, but British household electricity prices have been much higher than in most of Europe. The House of Commons Library says UK electricity prices were higher than those in all but three EU countries in the second half of 2025.
That makes the structure of Britain's electricity market worth examining.
How much of the bill is the cost of producing electricity?
How much is the network?
How much is government policy?
How much is VAT?
How much represents supplier costs and margins?
And could some of those costs be removed from electricity bills without simply transferring them somewhere else?
These are more fundamental questions than whether the next Ofgem announcement says 3%, 4% or 9%.
What happens when the next energy shock arrives?
This is perhaps the biggest reason to rethink the debate.
Britain cannot control international gas prices.
It cannot control wars in the Middle East.
It cannot control whether Russia's energy infrastructure is attacked or whether shipping through important international routes is disrupted.
But it can decide how exposed households are to those shocks.
The recent experience has demonstrated that when international energy prices surge, Britain eventually feels the consequences.
The price cap can delay and regulate the transmission of those costs.
It cannot make the costs disappear.
So should the price cap be scrapped?
Not necessarily.
There is still a clear consumer-protection role for regulating default tariffs.
But perhaps Britain should stop pretending that the price cap itself is the solution to high energy bills.
It is more accurately a mechanism for controlling how suppliers pass their costs on to customers.
The bigger policy challenge is reducing the underlying burden.
That could mean:
Better insulation.
More targeted help for households that genuinely need it.
A rethink of standing charges.
Reviewing which policy costs should be placed on electricity bills.
More competition and simpler tariffs.
And, perhaps most importantly, a serious examination of why British electricity remains so expensive compared with many European countries.
The question should no longer simply be:
"What will the energy price cap be next quarter?"
It should be:
"Why does it cost so much to heat and power a British home, and what can government actually do to reduce that cost?"
Because if the answer to every energy crisis is simply to announce another cap, followed by another increase in that cap, households may reasonably ask what exactly is being capped.
Perhaps it is time to stop measuring success by whether energy prices are below the next Ofgem ceiling.
The real test should be whether people can afford to heat their homes.
