Christmas Chocolates Lose Weight as Shrinkflation Bites into Festive Favourites

Christmas in Britain would not be the same without indulging in tubs of Quality Street or Celebrations, but 2025 brings unwelcome news for chocolate lovers. A new wave of shrinkflation, driven by global supply chain pressures, has seen the weight of classic festive confectionery trimmed down in response to escalating raw material costs – particularly cocoa – after consecutive poor harvests in West Africa. As supermarket shelves are stocked for the holidays, the downsized tubs and bars make the issue hard to ignore.

This year consumers will find themselves opening lighter containers: Quality Street tubs have had 50g shaved off their total, dropping from 600g to 550g, while Mars’s Celebrations now weigh 500g, compared to 550g in 2024. Iconic brands such as Toblerone and Terry’s Chocolate Orange have undergone similar reductions, with Toblerone’s large bar now 20g lighter at 340g and Terry’s Chocolate Orange falling from 157g to 145g. Amounts aside, individual chocolates inside have shrunk too, including Quality Street’s Purple One and Orange Crunch, both now notably lighter than in previous years.

The culprit behind this trend is soaring cocoa prices. Despite a slight recent dip, cocoa remains historically expensive, fuelled by poor harvests in Ghana and Ivory Coast, which together produce more than half of the world’s beans. UK official statistics highlight a 17.2% increase in shop prices for chocolate in the 12 months to July. Spiralling cocoa and dairy costs have led manufacturers to make painful choices, with leading companies such as Nestlé and Mondelēz International stating that trimming product sizes is a last resort, undertaken only after exhausting other measures to manage high production costs across ingredients, transport, and energy.

Retailers are not entirely absorbing the costs either: last year’s £4 promotional tubs now appear at £4.50 in some supermarkets, despite being lighter. Both Nestlé and Mondelēz maintain their pricing remains competitive and point to a range of pack sizes available, but ultimately, the final price lands in the hands of the retailer. Mars, facing the same pressures, has followed suit with its celebrated treats.

The annual Christmas chocolate rush is a fixture of the winter retail calendar, and these changes reflect the persistent volatility of the global commodities market. Chocolate, once considered a relatively cheap comfort, has now become a striking example of inflationary pressure on consumer goods. As price tags rise and contents dwindle, shoppers may be forced to savour their festive chocolates more slowly this season.
