The latest ONS Retail Sales Index figures showed a 3.7% year-on-year increase in overall sales.
Helen Dickinson, chief executive of the British Retail Consortium, said: “The fifth consecutive month of rising sales is a testament to the perseverance and innovation of retailers who continue to constantly adapt to the changing COVID landscape.
“Unfortunately, the lifting of many social restrictions in July did not bring about the anticipated boost in sales compared with the previous months, and the wet weather appeared to have dampened consumer enthusiasm for shopping.”
Ms Dickinson added that while retailers are keen to see growth continue throughout the second half of 2021, there are headwinds looming on the horizon.
She said: “Challenges in global shipping and the shortage of UK lorry drivers are creating some disruption for consumers and additional costs for retailers.”
