Source: the Office for National Statistics bulletin Consumer price inflation, UK: July 2026, released 19 August 2026, and the BBC's accompanying analysis by deputy economics editor Dharshini David, Inflation is heating up but don't expect another crisis, published 19 August 2026. Unit rates are from Ofgem's published price cap figures for 1 July to 30 September 2026.
The number everyone reported on Wednesday — CPI up from 2.6% to 2.9% — is the least useful figure in the release. It is an average of everything a typical household buys, and an average is precisely the wrong tool for a month in which one thing moved violently and most things barely moved at all. Gas prices rose 14.7% in the single month of July, the biggest monthly jump since October 2022. Food inflation, meanwhile, was 1.3% over the whole year, close to its lowest in five years. Those two facts belong to completely different households, and the 2.9% belongs to neither of them.
Here is what we think is the genuinely important part, and it is not in the headline. This is a gas rise, and gas is the one bill you have not paid yet this year. It landed on 1 July, in the middle of a warm summer, when the average boiler was doing almost nothing. The number in the statistics is real; the experience of it arrives around October, when the heating goes on. That gap — between when a price rise is recorded and when a household actually feels it — is where budgets quietly break, because nobody adjusts for a cost they have not yet noticed.
Where the 2.9% actually came from
The ONS is unusually blunt about the cause. Housing and household services jumped from 2.7% to 4.1% over the year, and prices in that category rose 0.9% in the month alone. The driver was the Ofgem price cap changing on 1 July 2026, which pushed standard variable gas tariffs up 14.7% and electricity up 3.6% in a single month. Ofgem's cap for 1 July to 30 September 2026 equates to £1,862 a year for a typical dual-fuel household paying by direct debit — a rise of £221, or 13%.
The cap rose because of what happened in wholesale energy markets. Ofgem prices each cap from a twelve-week observation window, and the window for this one ran from 18 February to 18 May 2026 — the first assessment period affected by the outbreak of conflict in the Middle East. In other words, the bill arriving on your doormat in October was effectively set by wholesale prices back in the spring. Energy bills are a delayed echo, not a live feed.
Worked example: what the £221 is actually made of
Built from Ofgem's published unit rates and standing charges, at the typical consumption the cap is quoted on: 2,700 kWh of electricity and 11,500 kWh of gas a year. Your own figures will differ by region, meter and payment method.
- Electricity now: 2,700 kWh at 26.11p plus 365 days at 57.19p = £913.71. It was £874.91 in the spring. Up £38.80.
- Gas now: 11,500 kWh at 7.33p plus 365 days at 29.04p = £948.95. It was £766.28 in the spring. Up £182.67.
- Total: £1,862.66 against £1,641.19 — the £221 the ONS quotes, reproduced from the rates.
So roughly £183 of the £221 is gas alone. The gas unit rate went from 5.74p to 7.33p per kWh: every unit of heat now costs 27.7% more than it did in June. Electricity contributed less than £39 of the increase, and the standing charges — the fixed daily fee — barely moved at all.
Spread evenly, £221 a year is £18.41 a month. That is what a level direct debit will do with it, and it is why the rise feels survivable in August. But you do not use gas evenly. The overwhelming majority of that 11,500 kWh is burned between October and March, which means a household paying on actual usage — standard credit, prepayment, or a variable direct debit — will meet most of a £183 gas increase inside about five months rather than twelve.
The part of the bill you cannot cut
Worth knowing, because it changes what saving energy can realistically achieve. At the current cap, the daily standing charges are 57.19p for electricity and 29.04p for gas. That is 86.23p a day, or £314.74 a year, payable before you switch a single thing on. If your annual bill is around £1,862, roughly a sixth of it is fixed regardless of behaviour.
The practical consequence: turning the thermostat down genuinely works on the other five-sixths, and the July rise fell entirely on the usage rates rather than the standing charges, so it is the part that responds to using less. But nobody saves their way out of £314.74. If money is tight, the fixed portion is an argument for checking entitlements and payment arrangements, not just for wearing another jumper. Our guide to cutting your bills without cutting your life covers the difference between the two.
What is not going up
Two things ran the other way in July, and both are worth putting in the budget alongside the bad news. Food and non-alcoholic drinks rose 1.3% over the year and were flat on the month — on a £100-a-week shop, that annual rate is roughly £68 over a whole year, against £221 on energy. And motor fuels fell: average petrol dropped 3.1p a litre in the month to 152.2p, and diesel fell 8.8p to 167.6p, which is about £1.55 off a 50-litre tank of petrol and £4.40 off diesel.
That is why transport dragged the headline rate down while housing pushed it up. If your household spends heavily on fuel and lightly on heating, your personal inflation rate in July was below 2.9%. If you heat a large or poorly insulated home, it was well above. Averages describe economies; budgets describe you. Working out your own is the whole point of a survival budget.
Four things worth doing this week
- Read your meter today and send it in. It takes two minutes, and it stops your supplier estimating your split across the 1 July price change. Then diarise the same job for 30 September, because the cap changes again on 1 October and an accurate reading on the boundary is the only way to be sure summer usage is billed at summer rates.
- Check your account balance, not your monthly amount. By the end of August a level direct debit should have you in credit — that credit is what pays for winter. If you are in debit in August, your monthly figure is set too low and October will be a shock. Ask your supplier to show you the calculation behind it.
- Work out your own cap figure, not the £1,862 average. Ofgem publishes unit rates and standing charges by region and payment method. Take your own kWh from last year's bills, price them at your rates, and you have a real number to plan against and to compare any fixed deal with.
- Check the help you may already qualify for. The Warm Home Discount is £150 off an electricity bill for eligible households, and your supplier's Priority Services Register is free to join. Both have to be claimed. Neither arrives on its own.
What is still uncertain, and when you will know
Three dates are worth writing down. Ofgem has not yet published the cap for 1 October to 31 December 2026, so any October figure quoted today is a forecast rather than a fact. The next inflation reading, covering August, is published by the ONS on 16 September 2026. And the Bank of England's next rate decision is 17 September 2026; Bank Rate is 3.75%, held there on 30 July 2026, and the Bank has said it expects inflation to rise later this year before returning to its 2% target in the medium term. The BBC reports economists expecting the headline rate to reach around 3.5% later in the year.
There is one piece of genuine perspective in all this, and it deserves saying plainly rather than being buried: even with October's expected step up, energy bills are forecast to sit the best part of £1,000 below the peak reached after the invasion of Ukraine. This is a squeeze, not a repeat of 2022. The households who came through that one best were not the ones who guessed the market right. They were the ones who knew their own numbers early enough to change something while there was still time to change it — which is exactly the window August gives you and October takes away. If your budget has drifted since the spring, rebuild it now rather than in December.
