The British Retail Consortium (BRC) has issued a stark warning that food inflation will remain above 5% well into 2026 if the retail sector faces additional tax hikes in the upcoming autumn budget.

While the UK government has committed to reducing business rates for retail, hospitality, and leisure properties, around 4,000 large shops may see their rates increase if they fall within the scope of a new business rates surtax targeting properties with a rateable value exceeding £500,000.

The BRC’s warning is compounded by fresh concerns over the cost of living, according to a new survey of 2,000 people conducted by Opinium for the organisation. The survey revealed that the primary concern for respondents in the year ahead was the issue of “prices rising faster than wages,” with 57% of respondents agreeing. The concern was even higher among working individuals, at 61%.

This outpaced concerns about tax increases (49%) and rising unemployment (26%).

The BRC said: “Food inflation will remain above 5% well into 2026 if the retail industry is hit by further tax rises at the autumn budget.”

Helen Dickinson, chief executive of the BRC, expressed concern about the potential economic consequences: “The government risks losing the battle against inflation and working families are understandably worried.

“With many people barely recovering from the last cost of living crisis, the chancellor will want to protect households and enable retailers to continue doing everything they can to hold back prices.”

She added: “The Treasury is currently finalising its plans to support the high street, including a much-needed reduction in business rates for retail, hospitality and leisure premises. However, the biggest risk to food prices would be to include large shops – including supermarkets – in the new surtax on large properties.

“This would effectively be robbing Peter to pay Paul, increasing costs on these businesses even further and forcing them to raise the prices paid by customers.

“Removing all shops from the surtax can be done without any cost to the taxpayer, and would demonstrate the chancellor’s commitment to bring down inflation.”

In the latest inflation data from the Office for National Statistics (ONS), inflation stands at 3.8%, almost double the Bank of England‘s 2% target.

Food inflation has seen a steeper rise, reaching 5.1%, the highest rate since the cost of living crisis began in 2022/23.

Retail price inflation has been steadily climbing over the past year, largely driven by the impact of the previous budget. The government’s decision to raise employment-related costs, coupled with the introduction of a new packaging tax on retail businesses, has placed significant upward pressure on consumer prices.

Last week, the Bank of England refrained from cutting interest rates, citing concerns that rising food prices were exacerbating inflationary pressures.

According to the latest minutes from the Monetary Policy Committee (MPC), the most recent budget added £7bn to retailers’ costs, driven by increases to employer National Insurance contributions, the higher national living wage (NLW), and the introduction of a packaging tax. The MPC attributed the rise in food prices to “labour costs and costs associated with new packaging regulation,” in addition to higher commodity prices.

In the upcoming autumn budget, due to be delivered on 26 November, chancellor Rachel Reeves faces the twin challenge of reviving economic growth while restoring the UK’s public finances, a task made harder by high borrowing costs.

She is widely expected to include tax increases in an attempt to balance the nation’s books.
