The national shopping event caused sales for the week ending 28th November to climb 4.6% to a record £187.7m.
The retailer enjoyed its best sales day in the company’s 151 year history, as customers stocked up on products at discount prices.
Black Friday, which took place on 27th November this year, was declared a disappointment after footfall fell by 4.5% compared to the year before, according to retail analysts Springboard.
However, the day was a success online, with internet sales surpassing £1bn in one day for the first time in UK history.
E-commerce sales on Black Friday jumped 36% compared to the year before, when British consumers spent £810m online.
During the week to 28th November, which does not include Cyber Monday, John Lewis’ sales of small electrical items jumped by 15%, whilst the TV department saw sales grow by 23%.
The department store also said that Lego sales were almost a third higher than last year, with 270 products selling every hour during the week.
John Lewis reached its previous all-time high during the same period last year, when Black Friday helped the department store boost its weekly intake to £179.1m. Sales in the last week of November were also 27.6% higher than two years ago.
However, analysts have cautioned that Black Friday might not be good for retailers overall as the event can simply bring sales forward from later in the year rather than generating new revenues. Black Friday can also hurt margins, impinge on consumer service and lead to stock oversupply.
