The industry body IMRG index found an ongoing consumer confidence in the wider online retail sector, with mobile retail also reporting 66 per cent year-on-year growth.
February also saw strong online sales in home and garden, as well as health and beauty including perfume and cosmetics, which reported 25 per cent growth on the same time last year.
Online-only retailers recorded an annual growth of over 20 per cent, the highest growth for three years, exceeding multichannel counterparts.
Tina Spooner, chief information officer at IMRG: Growth in the UK e-retail sector shows no sign of abating, with the Index performance coming in ahead of our expectations last month.
The exceptionally wet weather during February undoubtedly helped boost online sales as shoppers shunned the high street.
