Harris + Hoole, the fast-growing “artisan-style” coffee chain part-owned by Tesco, is set to replace the Costa concession at the supermarket’s store near Horsham, West Sussex.

The site will form part of the store’s mezzanine floor and will be the 23-strong chain’s first opening in the county.

The company recently secured licensing approval for two of its sites as part of a trial.

The trial has begun at the chain’s sites in North Finchley in North London and Walton-on-Thames, Surrey, and will be extended to further units if it is successful and council approval is given.

The group 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, 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.
