Total sales were up 2.6% in July, driven by fashion sales which increased 3.7% thanks to cold weather which brought forward the demand for autumn ranges.
Many fashion retailers also launched early sales in June to encourage shoppers to part with their cash.
Non-fashion sales increased 1.1% with luxury and beauty categories reporting strong performance, while homeware sales fell 2.1% during the month as consumers continue to reign in big ticket purchases.
Non-store sales, which includes online, phone and catalogue sales increased 39.9%, driven by online fashion stores.
Don Williams, national head of retail and wholesale at BDO LLP says: “The figures show consumers will continue to spend with retailers who can offer exciting products and promotions supported by consumer-orientated service.
“The retailers doing this can have the confidence to continue investing in their multi-channel offering and on quality retail sites in the best locations.”
