British retail sales rose 0.5 per cent in August, surpassing forecasts, as the hottest summer on record boosted spending on food, drink and clothes. The Office for National Statistics reported the figure on Friday, which was stronger than the 0.2 per cent decline predicted by economists polled by Reuters, and followed a 0.5 per cent fall in July. This provides the first official data on consumer spending in August, suggesting resilience despite rising fuel and energy costs.

In the three months to August, retail sales were up 0.9 per cent compared with the previous three months, a less volatile measure. Erin Brookes, European retail and consumer lead at Alvarez & Marsal, called it a positive end to an unpredictable summer, noting that extreme weather has driven shifts in consumer behavior. Jon Gough, ONS senior statistician, highlighted strong summer performance in supermarkets and alcohol sales, boosted by promotions and the World Cup.

Online sales, department stores, and fashion rebounded from July falls, but fuel sales declined as prices rose sharply. Retailers noted changing habits, such as partially filling tanks. This positive data follows July's unexpected economic growth, a boost for Prime Minister Andy Burnham ahead of his first Budget.

Paul Dales at Capital Economics estimated that even flat retail sales in September would yield a 0.7 per cent quarterly rise, boosting GDP. However, household finances face pressure from rising inflation (3.1 per cent in August) and potential interest rate hikes by the Bank of England.
