Record Heat Sends Online Retail Sales to Five-Year High 2026

Record heat in June drove online retail sales to a five-year high in Great Britain, according to new data from the Office for National Statistics (ONS). The volume of retail sales rose 1% month on month, beating analysts’ expectations of a 0.3% decline, fueled by scorching temperatures and World Cup spending. Online sales now account for the highest share of retail spending since spring 2021, when COVID restrictions were ending.

How Heatwave Conditions Boosted E-Commerce

The ONS reported that non-store retailers—primarily online businesses—saw sales soar 4.4% in June alone. While this was slightly lower than the previous month’s 6.1% growth, it still represented a bumper period for digital commerce. Consumers turned to the internet to buy air conditioners, outdoor products, and summer clothing, capitalizing on promotions and hot weather.

Clothing and Footwear Retailers Benefit

Clothing and footwear retailers had a strong month, with sales rising 1.9% from May—the biggest monthly increase since September. This surge was driven by demand for summer apparel as shoppers updated their wardrobes for the heatwave. Other non-food stores, including computer and telecoms retailers, also reported a 1.8% month-on-month increase.

Mixed Performance Across Retail Sectors

Despite the overall positive picture, not all sectors thrived. Department stores experienced a 1.7% monthly decline in sales after a 2.5% rise in May, when shoppers bought fans and paddling pools. Household goods retailers also struggled, with sales dropping 0.6% month on month. The table below compares key retail segments during June:
