Waitrose has opened the doors to a Little Waitrose shop in Wandsworth New Acres and refurbished stores in Marylebone and Clerkenwell as part of its £1bn nationwide investment.

The high-street retailer also announced a multi-million pound investment in London to transform and grow its estate.

Waitrose plans to refurbish the convenience stores in Crouch End and Old Brompton Road as well as the supermarket in Coulsdon before the end of the year.

Tina Mitchell, Waitrose interim managing director, said: “From our roots in Acton, where we opened our very first shop, to Streatham, which saw our first supermarket, and now our newest convenience shop in Wandsworth, London has always been home to Waitrose and central to our success.

“Today, as we open our 62nd store in the capital, we’re committing to investing millions to expand and refresh our portfolio. We pride ourselves on excellent customer service, and by continually listening to what our customers want and need, we are well-positioned for future growth in London and across the UK.”

Some of the developments at the Marylebone and Clerkenwell shops include a renovated bakery and improved fruit and vegetables sections, newly integrated self-service tills and staffed checkout areas.

The announcement comes after the supermarket retailer opened the doors to a new small-format store in Bristol last week.
