There is a £2bn-plus opportunity across convenience and foodservice, TWC Group’s latest Channel Track data points out, though with a warning that independent retailers are under pressure from supermarkets in small-basket missions.
Independent retailers and hospitality operators are continuing to hold their own against larger chains, but small-basket shopping in supermarkets is emerging as a significant competitive threat to convenience, according to new data from TWC Group.
The findings come from TWC’s Channel Track Market Monitor, based on 52-week card transaction data to July 2026, alongside continuous consumer research.
The data shows that there are 14 billion purchase occasions each year in foodservice/hospitality outlets and ‘convenience’ combined, worth £166.3bn per annum. However, a lot of convenience shopping (£20 spend or less) takes place in large supermarkets. In fact, over 50% of visits to large supermarkets are for ‘convenience’ trips .
UK consumers make five transactions each week on average, highlighting frequent purchasing behaviour.
The data agency has identified a £2bn-plus sales opportunity for wholesalers, suppliers and operators – split broadly between £1bn in foodservice and £1bn in convenience retail, although it said the actual opportunity is likely to be greater.
Small baskets put pressure on convenience
Almost £69.9bn is spent on convenience and small-basket shopping in the UK each year, according to TWC Group’s Channel Track data, with supermarkets accounting for a sizeable and growing share of these purchases.
Of the £69.9bn retail market, large supermarkets account for 31% of spend, while symbol, independent and other multichannel convenience operators account for 57% and supermarket convenience for the remaining 12%.
Crucially for independent retailers, small-basket shopping in supermarket is gaining share. TWC identifies small-basket supermarkets as the retail share winner, increasing their share by 0.3 percentage points, while Symbol & Independents (S&I) and other multichannel operators saw their share fall by 0.4 percentage points.
The scale of the opportunity – and threat – is underlined by the value of these missions. Small-basket supermarket trips of less than £20 are worth £21.9bn a year, equivalent to 20% of total supermarket spend. TWC also found that 59% of supermarket transactions are below £20, highlighting just how significant these smaller missions have become.
The data suggests that supermarkets have a particular advantage in the categories that lend themselves to these missions. TWC's category penetration analysis shows supermarkets and discounters significantly over-index against independent convenience outlets in fresh and chilled, frozen and grocery.
Against the independent convenience benchmark of 100, supermarkets and discounters score 237 for fresh and chilled, 218 for frozen and 189 for grocery. Even supermarket convenience outlets outperform the independent benchmark, scoring 154, 131 and 128 respectively across the three categories.
