Whole Foods Market, the US natural and organic grocer, saw its pre-tax losses narrow in the UK by £30m in 2009 - despite it seeing sales decline by more than 11% to £43m.

The UK arm reported a loss of £4.3m for the year ending 27 September 2009, compared with £35.9 for the previous year.

The group blamed the decline in sales on the “challenging retail environment” and said that changes to its product mix and pricing would help drive improvements.

The group’s London 8,000 sq ft flagship, which opened in a former department store in Kensington High Street in 2007, has almost an entire floor devoted to foodservice, featuring several restaurants and a pub.

However the store was criticised for a lack of car parking, a costly seafood counter and a Champagne and oyster bar, which has subsequently closed.
