A total £24.6bn was spent in the retail sector last month, compared to £24.4bn in January and £23.9bn the previous year, the ONS said.
Food stores saw sales volumes drop 0.1pc between January and February, despite customers stocking up on cupboard staples during snowfall and freezing temperatures at the beginning of the month.
Non-food stores fell 1.5pc month-on-month, driven by a 1.2pc drop in clothing and footwear sales.
The decline came despite continued evidence of heavy discounting among retailers, which helped cut the overall rate of consumer prices index inflation to 3.3pc in February.
The other stores sector, which covers a range of products from carpets to rugs and toiletries to watches, fell 3pc.
The ONS identified within that sub-sector particularly steep declines in specialised stores such as fine art dealers and antique retailers.
The downwardly-revised volume figure for January, which had initially given some hope of a boost to the overall economy from the retail sector at the start of the year, was driven by a weak performance from smaller retailers.
Many small businesses submitted their survey results later, the ONS said, and they were worse than estimated.
The non-store retailing sector, which includes internet sales, also declined 0.4pc in February.
