“While the UK clothing market is seeing subdued growth, Primark has significantly underperformed the overall market,” says Tamara Sender-Ceron, an associate director at market-research agency Mintel, adding that it faces “increased competition”.
Some shoppers point out that online marketplaces like Shein and Temu have even lower prices, a huge range of products, and – crucially – home delivery, something Primark lacks.
At Primark’s biggest London store on Oxford Street, which BBC News visited this week, Serena Milius has just popped in with her 12-year-old daughter to look at pyjamas, socks and the new Stranger Things range.
Serena used to do most of her shopping at Primark – until Shein took over.
“Shein’s our main thing,” the 34-year-old finance manager from Tooting, south-west London, says.
She says her wardrobe is now 90% Shein, and goes to Primark for “little bits and bobs” like flipflops, candles, socks and cosmetics dupes.
