Bakers’ shops have seen their share of the sandwich market slip in the past year with sandwich and snack bars and supermarkets growing their sales, according to a new report from market research company Key Note.

The report says bakers’ shops (a category that includes the Greggs chain) are still the dominant player in UK sandwich sales but saw value share fall from 28.6% in 2005/06 to 26.4% over the year to May 2007. Volume share dropped from 35.3% to 33.5% in the same period.

Supermarkets have increased volume sales to give them a 13.5% market share, up from 12.2%, with value sales up from 12.2% to 13.4% over the same period.

Sandwich chains had a 9.8% value share of the market, with Subway the dominant player with a 7.2% share of sandwich sales by value, up 4.2%.

Total sandwich sales were £3.73bn in the year ending May 2007, up from £3.61bn the year before. Some 2.46 billion packs were sold in 2007, down from 2.54 billion the previous year.

The report also says that 51% of sandwiches sold are wedges, 17% rolls and baps, 13% baguettes and 5% sub rolls. Other sandwich carriers, such as pittas and wraps, accounted for 10% of volumes.

The top 14 sandwich shop brands, such as Pret A Manger, had 2,833 outlets in 2006, up 430 year on year.

There were also 2,545 branded coffee shops in the UK in 2006, up from 1,587 in 2005, giving the brands a 34% market share of the coffee shop market.
