This was a marked improvement, however, on the previous week when the heavy snow led to a year-on-year sales fall of 17.1 per cent.
Fashion was the best performing area for the department store and was the only category to achieve a sales increase for the week.
Sales for John Lewis’ Waitrose stores were up 4.9 per cent with the bad weather having a positive impact on its sales over the Valentine’s weekend.
Waitrose finance director Richard Mayfield said: “The rainy weather swept across much of the country last week and our Valentine's Meal Deal provided a great value and cosy alternative to eating out. The staying-at-home theme continued, with sales of cooking ingredients rising by more than 20 per cent.”
