Black Friday is predicted to bring £10.4bn in sales to the UK, up 3.1% on last year, a new report from GlobalData has shown.
Fashion and beauty will be the best-performing sector, according to GlobalData, growing 3.8% on last year.
Overall, the period between Monday 19 November and Monday 26 November is expected to account for 10.5% of sales in the fourth quarter.
However, despite the boost, growth in retail will continue to slow year-on-year as a result of price slashing throughout the year.
Out of the 2,000 shoppers surveyed, 39.9% said they are planning to make a Black Friday purchase and 55.8% are delaying Christmas shopping to wait for promotions.
Zoe Mills, retail analyst at GlobalData, said: “It highlights how Black Friday is encouraging shoppers to hold back buying full price items and purchasing during other discounting periods prior to the event as shoppers predict that retailers will drop prices even further during Black Friday, heavily impacting retailer sales in the weeks prior to the event.”
