Energy price cap January 2027 fixed deals: £1bn help reported

The chancellor is planning an energy-bill intervention worth more than £1bn in this month’s budget, the Guardian reported on 6 October 2026, after ministers became alarmed at forecasts of January rises of hundreds of pounds. The paper cites forecasts that the cap could rise by as much as £442, well above the £276 implied by the £1,999 figure Cornwall Insight has put forward.

For households weighing up the energy price cap January 2027 fixed deals question, the picture is therefore more uncertain at both ends. The possible rise is bigger than first thought, and some government help is being worked on, but nothing has been confirmed. Fixed deals priced below the cap are still available now, according to Birmingham Live.

What the Guardian reports about the budget plans

According to the Guardian, John Healey, the chancellor, is working on plans to spend more than £1bn to help energy consumers, with the bulk likely to go on increasing the warm homes discount. That is currently a £150 discount on energy bills for households on certain benefits. The paper said Mr Healey is understood to be considering adding a further £100, paid for by taxpayers rather than bill-payers, as the existing discount is. It said final decisions have not been made.

The Guardian also reported that Mr Healey is set to rebuff a call from the energy secretary, Miatta Fahnbulleh, for billions more to be spent on removing levies from bills altogether. Her plan would cut bills for all consumers by as much as £120, but would cost as much as £3.2bn. Government sources had previously said a VAT cut on electricity announced in the previous administration would be the last support this year, but the paper said they have become concerned that a rise of up to £442 would entirely erode its impact.

Looking further ahead, the Guardian said energy officials are working on more radical changes that could follow the budget, including a social tariff and a "rising block tariff". It said a social tariff would need a large amount of data collection and would take far longer than the next few weeks. A Treasury spokesperson said decisions on tax are "a matter for the chancellor to set out at fiscal events, rather than routinely commenting on rumour, speculation or proposals". Alex Chapman of the New Economics Foundation told the paper: "A serious price spike is coming, and without action, bills will exceed the peak of the last crisis."

The January price rise in plain English

Ofgem, the regulator, sets the price cap every three months. On 1 October it rose 3.6%, from £1,663 to £1,723 a year, for a typical dual-fuel household paying by direct debit in England, Scotland and Wales. Cornwall Insight forecasts a further 16% on 1 January 2027, which would take the figure to £1,999, a rise of £276. Birmingham Live said other industry experts expect about 20%, and Martin Lewis used a similar figure.

The Guardian’s figure of up to £442 sits above all of these. Added to today’s £1,723, it would give a cap of £2,165, which is our own sum rather than a published forecast. The rise would be about 25.7%, and £166 more than the £276 implied by £1,999. The Guardian does not say who produced the £442 forecast, and it describes it as the most the cap could rise by, so treat it as the top of the range. None of these are confirmed prices.

Ofgem describes the cap as the "maximum amount your supplier can charge for a unit of energy and standing charge together". It adds: "It does not limit the cost of your total bill. The more energy you use, the higher your bill will be." The Mirror reported that the expected January rise is linked to the situation in the Middle East involving the US, Israel and Iran. A fixed tariff works differently: Mr Lewis said the standing charge and unit rate you sign up to stay the same for the whole length of the fix, which is usually one or two years.

Who pays more, and who is protected

Anyone on the default price cap is exposed to the January change. Streamline put the number of households still on standard variable tariffs at roughly 20 million. Those customers pay whatever the cap becomes on 1 January, which falls in the coldest part of the year, when use is highest.

A fix shields you from the cap, but not from every increase. Mr Lewis said bills on a fix can still rise for two reasons: you use more energy, or your monthly direct debit is set on an estimate that is higher than your real use. In the second case he advised customers to tell their supplier they can prove their use is lower and ask for the payment to be reduced.

Mr Lewis was also clear about who his advice is for. "What I’m saying is only for those who are on a price cap," he said. If you are already on a fix or a special deal, he said, you are likely paying less than the fixes available now, so the decision is "very, very different".

Streamline reported that VAT on domestic electricity has been cut from 5% to zero from October 2026 to March 2027, while VAT stays at 5% on gas, so dual-fuel households remain exposed to wholesale gas costs. The Guardian’s reporting suggests the government fears a January rise could wipe out the benefit of that cut. The extra help now being drawn up is, on the paper’s account, aimed mainly at households on certain benefits, so many households on the cap may not receive it.

Worked example: what a fix could save before the cap rises

Take a typical dual-fuel household on the cap. If Cornwall Insight’s forecast holds, its annual cost moves from £1,723 to £1,999, an extra £276, or £23 a month on average. If the Guardian’s top figure of £442 were reached instead, the extra would be about £37 a month. The table below uses fixes listed by Birmingham Live as at October 2026. The last two columns are our own subtraction, not figures from the sources. Tariffs change frequently, so check current prices with suppliers.

So the cheapest listed fix, at £1,615, would cost £384 less over a year than the £1,999 forecast cap and £550 less than the higher £2,165 case. Against today’s cap the gap is £108. These savings depend on the forecasts being right and on the household using a typical amount of energy.

Prices also differ between reports. Streamline gave a Fuse 12-month fix at £1,675, which it said was £48 below the current cap and £324 below the January forecast. Tariffs change often, so the figure you see at the time of switching is the one that counts.

How to lock in energy prices in the UK: what to check

Start by comparing on your own usage rather than the typical-household headline. Switch Insights advised readers to "compare the annual estimate at your own usage, which matters far more than the typical-household headline". Mr Lewis said the cheapest fix depends on where you live and how much you use, and recommended MoneySavingExpert’s Cheap Energy Club, which he described as, as far as he is aware, the only comparison that shows the whole market by default.

Then read the terms. Switch Insights advised keeping exit fees at £100 per fuel or below, checking the standing charge separately and confirming any condition, such as needing a smart meter. Streamline reported that many of the most competitive fixes carry exit fees of £50 to £100 per fuel if you leave before the final 49 days. For a dual-fuel home that could mean £100 to £200 to leave early, which matters if prices fall after you sign.

Finally, look at use as well as price. Streamline reported that lowering a combi boiler’s flow temperature from 70-80°C to 60°C or below could save a typical household about £60 a year. If you receive certain benefits, keep an eye on the budget, since the Guardian says the warm homes discount is the likeliest vehicle for extra help. This is general information, and whether to fix is a judgement for each household.

Your questions answered

Should I wait for the budget before fixing?

The sources do not settle this. The Guardian says the extra help is still being decided and is likely to go mainly to households on certain benefits, so it may not change the position for everyone on the cap. Uswitch’s Sabrina Hoque told Birmingham Live that fixing now means "today’s rates are locked in through the winter and beyond". Fixed prices change often, so a deal you can see today may not be there later, and exit fees are the cost of changing your mind.

What does Martin Lewis say about fixing energy prices?

Mr Lewis said that if you are on the price cap, a fix prevents the likely rise of around 20% in January. He said a comparison now would show fixes cheaper than the current cap. He also warned that a fix locks the price of each unit, not your total bill, so using more or paying an inflated direct debit estimate can still raise what you pay.

Are energy prices set to fall in 2026?

The sources point the other way. The cap rose to £1,723 on 1 October, Cornwall Insight forecasts a further rise to £1,999 on 1 January 2027, and the Guardian cites forecasts of up to £442. Streamline said a fall in wholesale prices is possible but would be unexpected, which is why it said low exit fees matter. None of the sources forecast a fall in the near term.

What if I am already on a fixed deal?

Mr Lewis said your position is different if you are already on a fix or a special deal. You are likely paying less than the fixes on offer now, so the case for switching is weaker. Check any exit fee before you leave, and check your direct debit matches your actual use. The sources do not say how any new government help would reach customers on fixed tariffs, so ask your supplier if you are on a qualifying benefit.
