Three of Britain’s best-known high-street names have been censured by the Advertising Standards Authority (ASA) after the watchdog found their Black Friday promotions overstated the true value of the discounts on offer, in a ruling that will sharpen the focus on pricing claims across the retail sector this Christmas.
The regulator concluded that John Lewis, Boots and Debenhams each breached the advertising code by presenting reference prices that could not be substantiated as genuine established selling prices, the long-standing benchmark by which savings claims are judged.
In John Lewis’s case, two laptop promotions came under scrutiny. A MacBook Air advertised with a £150 saving against an earlier price of £849 was found not to meet the threshold, with third-party pricing data indicating the higher figure had only been in place briefly before the promotion began. A separate Asus laptop, advertised with a £450 reduction, was likewise judged not to represent a genuine saving.
The ASA also upheld complaints against Debenhams over banners offering discounts of “up to 44%”, and against Boots over a fragrance promotion marked down from £80 to £60, ruling that there was insufficient evidence in either case that the higher prices reflected the goods’ usual selling prices.
The interventions form part of the ASA’s expanding programme of AI-assisted monitoring, which has already produced action against travel firms and the online retailer Very over similar pricing claims. The watchdog has made clear that its proactive Active Ad Monitoring system is being scaled up to identify suspect promotions at speed, particularly around high-stakes trading events such as Black Friday and the January sales.
Emily Henwood, an operations manager at the ASA, said consumers were entitled to expect that Black Friday bargains were the real thing. Retailers, she added, must remember that promotional events do not buy them an exemption from the rules and that any advertised discount must be capable of being proved.
The rulings sit within a broader pattern. Consumer research has repeatedly shown that headline Black Friday savings are not all they seem, with one widely reported study finding only one in seven so-called Black Friday bargains offered a genuine discount compared with prices charged at other points in the year. The CAP Code is unambiguous on the point: under its promotional savings claims guidance, reference prices must reflect a genuine, established usual selling price and the higher figure must have been available for a meaningfully longer period than the discounted one.
For boards, finance directors and marketing leads at SMEs that take their cue from larger retailers, the message is straightforward. The regulator is no longer reliant solely on consumer complaints to police pricing; algorithmic monitoring is doing much of the heavy lifting, and the bar of proof for “was/now” claims is being applied with increasing rigour. Recent enforcement against Nationwide over its branch closure advertising and Huel and Zoe over undisclosed commercial ties to Steven Bartlett underline that the ASA is willing to take on household names where it believes consumers have been misled.
George McLellan, a partner in the dispute resolution team at law firm Sharpe Pritchard who has defended advertisers in ASA investigations, said the latest decisions showed the regulator at its most effective. “These rulings show the ASA at its most effective: tackling straightforward cases of potentially misleading advertising that directly affect consumers,” he said. “I hope the ASA and CAP continue to prioritise this kind of core regulatory enforcement over broader attempts to influence social policy through advertising rules.”
For consumers, the practical takeaway is that scepticism remains the sharpest tool in the shopper’s arsenal. For retailers, the cost of a censure now goes well beyond a corrective ruling: reputational damage, the prospect of follow-on action from the Competition and Markets Authority under its strengthened consumer powers, and the wider chilling effect on customer trust all argue for tighter discipline around how discounts are constructed and communicated.
If Black Friday is to remain a serious commercial fixture rather than a marketing folk tale, the burden of proof, the ASA has made clear, sits squarely with the retailer.
