B Leader bio

A commercial employment lawyer by background, Thomas developed a practice supporting corporate transactions for private equity clients in the consumer sector and earned a reputation for a pragmatic commercial approach.

In 2012, Thomas took part in the UK’s first masters-level course on the Circular Economy and developed a passionate belief in the opportunities and benefits of the ‘triple bottom line’ approach to business.

He left law in 2014 and joined an organic food production and retail business as Interim Managing Director where he turned the business around before supporting the shareholders through the successful sale of the business to a trade buyer.

Thomas’s consulting practice, Greenheart Consulting, became a certified B Corporation in August 2017 and re-certified in June 2020 with a score of 105.4. He is a trained and experienced B Leader and B Corp Ambassador as well as a trustee of the Soil Association charity and a non-executive director of its two trading subsidiaries.

“Tom was an absolute pleasure to work with and his expertise and experience were instrumental in us achieving our B Corp certification in record time.”
Garreth Griffith, Chief Impact Officer, Habito

“Thomas has done some amazingly thorough and detailed work for us, reviewing our supplier code of conduct and B Impact Assessment. His suggestions have been well thought through and clear to follow, and his inputs have definitely taken our work forward more quickly than we would have been able to ourselves. It’s been great to get this sense check from someone with his level of experience and expertise in these issues, and we look forward to working with him on other challenges going forward.”
Ruvan Mendis, COO, graze

“It has been a pleasure working with Thomas on our B Corp journey. His expert guidance and support throughout the certification process enabled the team to achieve the success they so richly deserved. Thank you. We look forward to working with you again in the future.”
Stephen Boobyer, CEO, World of Books Group

“Thomas played a pivotal role in helping our business secure our B Corp accreditation. He guided us effortlessly through the process. His unique combination of absolute expertise in this specialist area and his background in running businesses is pretty special. He understands the fine balance between the theory and putting things into practice in reality – more than any consultant I’ve ever worked with! He just gets it. Not only did he totally get us, our business and our objectives, but we really felt he cared about them too and helping us deliver positive change and positive results.”
Clare Twiss, Head of Marketing, Vegetarian Express
