Total retail sales figures were up 4.5% over the month, with a 2.2% like-for-like increase, but the BRC said the figures were distorted by the slump caused by the January snow.
Over the quarter covering December to February, like-for-like sales were 2.1% ahead, with total sales up 4.1%, according to the BRC-KPMG Retail Sales Monitor.
Food and drink sales growth slowed after shoppers stocked up in January, the BRC said.
Internet and mail-order showed strong growth in February, with sales 15.5% higher than they were a year ago.
“Despite appearances, these results are not that strong,” said Stephen Robinson, BRC director general. “However, consumer confidence is certainly up on this time last year.
“When the weather-related distortions are stripped away, it’s clear consumers are still being cautious.”
