Inflation is back up to 3.5%, and almost all of it is one thing at the pumps
What happened
On 21 October 2026 the Office for National Statistics published inflation figures for September 2026. The headline measure, CPI, rose to 3.5% in the year to September, up from 3.1% in August. CPIH, which also includes housing costs for owner-occupiers, rose to 3.6% from 3.3%. The biggest thing pushing the figure up was transport, and within transport it was mainly motor fuels. Transport prices were 6.6% higher than a year earlier. Motor fuel prices were 29.8% higher. That is a very large number, and it is doing most of the work in this month's rise. Pulling in the other direction were restaurants and hotels, where annual inflation eased to 3.8% from 4.1%, mostly because hotel prices were rising more slowly than before. Food and non-alcoholic drinks inflation was 1.3% over the year, unchanged from August. After several years in which food was the painful line on the receipt, that is a notably calm figure. Inflation measures the rate at which prices are rising, not whether prices are high. A fall in the inflation rate does not mean things get cheaper. It means they are getting more expensive more slowly.
Why this matters
The composition of this month's figure matters more than the figure itself. When inflation is driven by food, it hits everyone, because everyone eats. When it is driven by motor fuel, it hits unevenly. If you drive a lot, this month hurt. If you do not drive, you may barely have noticed. That unevenness is easy to miss in a national average. A rural household making two long car journeys a day is living in a very different economy from someone with a bus pass and a short walk to the shops. Fuel also leaks into other prices with a delay. Deliveries, taxis, tradespeople, buses and food distribution all run on diesel. A 29.8% annual rise in motor fuel prices does not stay at the pump. There is a second reason these numbers matter. September's CPI figure is traditionally the one used in setting some benefit and pension uprating decisions. That makes this a figure with direct consequences for household incomes, not just a statistic. And the calm in food prices is genuinely good news, but it is good news about the rate of change. Food prices are still well above where they stood a few years ago. A 1.3% rise on top of a high base is still a rise.
What the evidence actually says
Three cautions are worth keeping in mind when reading any inflation headline. First, the basket is an average, not your shopping. The ONS tracks a representative basket of goods and services across the whole population. Your personal inflation rate depends on what you actually buy, how far you drive and how you heat your home. Second, a single month's move can be driven by one category. This month it was motor fuels. Because inflation is measured against the same month a year earlier, an unusually low or high month in September 2025 affects the comparison. Economists call this a base effect, and it is one reason single-month jumps should not be over-read. Third, CPI and CPIH will usually differ, and neither is wrong. CPIH includes the cost of owning and living in your home, so it tells you something CPI does not. The ONS publishes the detail behind the headline, including the contribution of each category, so the claim that motor fuels drove the rise is not interpretation. It is in the data. What the figures do not tell you is what happens next. Fuel prices are set largely by global oil markets and the exchange rate, and nobody reliably forecasts either.
Qurexa perspective
A 29.8% annual rise in motor fuel prices changes the maths on small journeys, and one of the most common small journeys in Britain is the trip to collect a prescription. For a lot of people that is a short, cheap errand. For others, especially in rural Lincolnshire, it is a ten-mile round trip, or a bus that runs twice a day, or a favour asked of a neighbour. Qurexa delivers prescriptions, which removes that journey. We are not pretending that is an answer to inflation. But when fuel is the single biggest thing pushing prices up, the journeys you do not have to make are worth counting. The other thing worth knowing is that NHS prescription charges have their own cost-saving routes, which many people who pay for several items a month never check. A prescription prepayment certificate can cap what you pay, and your pharmacist can tell you in a minute whether it would save you money.
Practical advice
On fuel: the cheapest easy win is not where you buy but how you drive. Lower tyre pressure, a roof box left on all year and heavy acceleration all cost real money. Fuel price comparison data is now published for most forecourts, so checking before a big fill-up is worth a minute. On food: the 1.3% figure is an average across the basket. Own-brand switching still typically saves more than shopping around between supermarkets, and the biggest single saving for most households is throwing away less. On benefits and pensions: if your income is linked to uprating, September's CPI figure is the one to watch for announcements. Check that you are claiming what you are entitled to. Pension Credit in particular is widely under-claimed, and it unlocks other help. On prescriptions: if you pay for more than about one prescribed item a month in England, ask your pharmacist about a prepayment certificate. Some people are exempt from charges altogether and do not realise it. On energy: this is the month to check your tariff rather than next month, because switching decisions get harder once the cold sets in.
What to know
UK CPI inflation rose to 3.5% in the year to September 2026, from 3.1% in August, and CPIH rose to 3.6% from 3.3%. The main driver was transport, particularly motor fuels, which were 29.8% higher than a year earlier. Restaurants and hotels pulled the figure down slightly. Food and non-alcoholic drink inflation held steady at 1.3%. Because this month's rise is concentrated in fuel, it lands much harder on households that drive a lot, and fuel costs tend to feed into other prices with a delay. September's CPI figure is also the one traditionally used in some uprating decisions, so it has consequences beyond the headline.
