Harris + Hoole, the coffee shop venture from Taylor St Barista, in which Tesco has a stake, is understood to be in talks on a further eight sites as it looks to get close to the 30-site mark by the year end.

The 23-strong group is in different stages of negotiations on sites in Hatfield, Horsham (which would be its first in West Sussex), Kings Cross, New Malden, Sudbury, Surrey Quays and Weybridge.

The company, which recently opened in the Tesco Extra in Watford, has a further opening lined up along with Giraffe at the Tesco Extra Cheshunt.

M&C Report understands that Tesco has put aside a considerable sum to invest in the roll out of Harris + Hoole, which it believes can grow into an estate of hundreds of sites.

It recently launched in St Margarets, Highbury and Guildford.
