Phil’s career began after completing a degree in Business Studies, where he first developed his passion for understanding consumer behaviour and the power of branding. In 1982, he joined United Biscuits as a Product Manager, gaining valuable early experience in product development and marketing strategy. He later moved to Unilever, where he spent fifteen years progressing through a variety of senior marketing and commercial leadership roles. During this time, Phil developed a reputation for innovative thinking and customer-focused marketing, eventually becoming Director of Relationship & Interactive Marketing. While at Unilever, he helped establish the Jigsaw Consortium, introducing CRM strategies to major global businesses including Kimberly-Clark and Cadbury. These experiences gave Phil a deep understanding of how consumer relationships influence long-term brand growth.

Following his success at Unilever, Phil continued building his career in senior leadership positions across internationally recognised brands. He became e Capabilities Director at Diageo, helping the business strengthen its digital and marketing capabilities during a pivotal period of transformation. Phil then joined First Choice Holidays as Group Marketing Director before moving to T-Mobile, where he became VP Consumer Business and later VP Brand Development Europe. During his time at T-Mobile, Phil played a key role in relaunching the brand across ten European countries through the hugely successful ‘Life Is For Sharing’ campaign. This included the iconic Liverpool Street Station flash mob advertisement, one of the UK’s earliest viral campaigns, which significantly increased sales and strengthened customer loyalty. The campaign remains one of the most recognised examples of emotionally driven advertising and showcased Phil’s ability to combine creativity with behavioural insight.

In 2010, Phil founded the UK branch of DECODE marketing ltd., bringing together traditional brand management with cutting-edge neuroscience, cognitive psychology and behavioural economics. Through DECODE, Phil has advised organisations on how to create more effective marketing by understanding how people truly make decisions.

Phil further strengthened his industry reputation through the success of ‘Decoded: The Science Behind Why We Buy’, which received widespread praise from leading marketing professionals and became essential reading for brand leaders worldwide. In 2022, Phil released the updated second edition of the book and was also elected a Fellow of The Marketing Society, recognising his outstanding contribution to the marketing industry.
