Harry won the Roux Scholarship in 2016 when he was 26. He did his stage at Saison in San Francisco with celebrated chef Joshua Skenes.

In autumn 2021, Harry announced his new restaurant X by Harry Guy to open in Chester in summer 2022, and the fulfilment of a dream to champion the highest calibre of natural produce, showcase culinary excellence and deliver exceptional hospitality. At X, Harry will take guests on a ‘gastronomic journey that will undoubtedly entice the senses’. As Harry's first solo venture, the 50-cover restaurant will serve ‘flavour-first’ British dishes, sourcing the best produce from across the UK with a menu that embodies the tastes, textures and aromas of the natural world. Working closely with quality suppliers and farmers in the Cheshire countryside and beyond, the restaurant is set to be uncompromising in bringing the freshest, traceable ingredients to the table.

Prior to this, Harry was working as operations manager and cooking for Simon Rogan’s London restaurants Roganic and Aulis London. Harry took on this role to expand and broaden his knowledge on the business side of the company. Having to think about the business as a whole rather than running the day to day of a kitchen, he got the vital experience needed for owning his own restaurant.

Harry decided to become a chef at the age of 14, while working in a kitchen as a pot washer. After attending North Leamington School, he decided to study at Stratford-Upon-Avon College for three years on its Advanced Culinary Skills course. Harry then went on to work at the highly regarded and then Michelin-starred Mallory Court Hotel in Leamington Spa, under the guidance of Simon Haigh. He moved next to the two Michelin-starred L’Enclume in Cartmel, Cumbria, where he was mentored by Roux Scholar 2011 Mark Birchall and Tom Barnes in his role as junior sous chef, where he stayed for two years.

When Harry won, he was support and development chef for the Eden Hotel Collection in Stratford-Upon-Avon, a hotel collection that includes Mallory Court, where he first started his career. Harry also spent a short time in the South West of France near Agen.
