The numbers
British shoppers caught a break in September. UK food inflation eased to 2.5%, down from 2.8% in August, according to the BRC-NIQ Shop Price Monitor published on September 29. The figures, based on prices collected between September 1 and September 7, suggest that the sharp price jump seen in August — partly driven by summer heat effects on supply — is at least partially reversing.
The details beneath the headline are encouraging for grocery budgets. Fresh food inflation fell to 2.6% from 3.0% in August, dropping below its three-month average of 2.9%. Ambient food inflation — the tins, packets and jars — slowed to 2.2% from 2.5%, though it remains above its three-month average of 1.9%. Overall shop price inflation, which includes non-food, edged down to 1.4% from 1.5% in August, slightly above the three-month average of 1.3%. Non-food inflation slowed to 0.8% from 0.9%, helped by heavy discounting on back-to-school essentials including books, stationery, footwear and electricals.
Context is important: August's figures had marked a two-year high for shop price inflation, which jumped from 0.9% in July to 1.5%. September's moderation does not erase that spike, but it does suggest August may have been a peak rather than the start of a sustained climb — at least for now.
The slowdown was not an accident of the data. Retailers actively extended promotions on meat and dairy to win back shoppers after a hot summer, and those discounts show up directly in the fresh food numbers. "Shop price inflation edged down this month, with food inflation falling as competition between retailers continued to deliver value for shoppers," said BRC Chief Executive Helen Dickinson. "Promotions helped bring down meat and dairy prices."
This is the supermarket price war doing what it is supposed to do. Britain's grocery market remains one of the most competitive in the world, with the major chains watching each other's prices in near real time. When one retailer leans into promotions on high-visibility categories like meat and dairy, the others follow — and the BRC-NIQ index, which tracks thousands of prices across the market, captures the collective effect. For shoppers, the practical lesson is the familiar one: the headline inflation rate is an average, and the actual price you pay depends heavily on buying the promoted lines.
Mike Watkins, NIQ's Head of Retailer and Business Insight, added a note of caution about the months ahead, observing that the fourth quarter is expected to bring tighter household budgeting — meaning retailers will still need to absorb cost increases wherever possible to keep shoppers spending through the festive season.
The exceptions: fruit and chocolate
Not every aisle got cheaper. Poor harvests across Europe pushed up fruit prices, a reminder that the grocery supply chain remains exposed to continental weather. A difficult growing season on the continent feeds directly into British fruit bowls, since the UK imports a large share of its fresh produce. Shoppers who noticed berries and stone fruit costing more in September were not imagining it.
Chocolate and confectionery also remained elevated, kept high by global commodity prices. Cocoa markets have been volatile, and the cost pressures are still feeding through to the shelf. With the festive season approaching — the period when chocolate sales spike — this is the category to watch. If commodity costs do not ease, Christmas confectionery could test shoppers' tolerance for higher prices even as the broader food inflation picture improves.
The split between falling meat and dairy prices on one hand and rising fruit and chocolate on the other illustrates why single inflation numbers only tell part of the story. A household's experienced inflation depends on what it actually buys: a family heavy on fresh meat and dairy will have felt September as a relief, while one buying lots of fresh fruit and chocolate may barely have noticed the slowdown.
Retailers at their limit
Beneath the better-than-expected numbers runs a warning from the industry. "Retailers have absorbed wave after wave of extra costs, but there is a limit to what businesses can shoulder," Dickinson said. The BRC points to a daunting list of incoming pressures: higher business rates set to hit in April, alongside rising employment costs, energy bills and packaging taxes.
The politics are explicit. Dickinson described the upcoming October 28 Budget as "a fork in the road," arguing that the Chancellor could help keep prices down by freezing the business rates rise and removing shops from the business rates surtax — or risk pushing even more costs onto consumers. Whether or not the government acts, the message to shoppers is clear: the current promotional generosity is being funded by retailers' margins, and those margins are finite.
This is the structural tension in British grocery. Retailers are absorbing costs to protect volumes, because in a market this competitive, losing a shopper to a rival is more expensive than eating a margin hit. But absorption has limits, and the BRC is signalling that those limits are approaching. If cost pressures continue to build through the winter, the promotional shield that cooled September's numbers may not hold indefinitely.
The road to Christmas
What does all this mean for the months ahead? The near-term outlook is cautiously positive: promotional activity is likely to intensify as retailers compete for Christmas spending, which should keep a lid on food inflation through the festive season. The fourth quarter is the most important trading period of the year for British grocers, and none of them can afford to look expensive in December.
The medium-term picture is murkier. Britain's broader official consumer price inflation rose to 3.1% in August, and the BRC's shop price measure — while useful — covers only a slice of household spending. Energy costs remain a key source of uncertainty for both businesses and households, and the April business rates changes loom over retailers' 2027 planning.
For now, though, September's data offers something British shoppers have not had much of lately: a month in which the grocery bill got slightly easier. In a year of cost-of-living pressure, that counts — even if the industry's warnings suggest shoppers should enjoy the promotions while they last.
