Meet the team

Sir Charles Dunstone CVO - Executive Chairman, TalkTalk Group

Sir Charles Dunstone set up Carphone Warehouse in 1989 aged 25 after he began his business career selling mobile phones out of his flat in Marylebone. Charles led Carphone Warehouse’s expansion across the UK and beyond and in November 2002, acquired Opal Telecom, providing the opportunity to launch a cost effective, residential, fixed line service to customers.

TalkTalk was launched as a subsidiary of Carphone in 2003 with the unique service proposition that all customers talk to each other for free, forever – our first big disruption to the industry. He led the demerger and subsequent listing of TalkTalk from Carphone in 2010, and remains a major investor following the take-private in 2020.

Through his investment vehicle, Freston Ventures, Charles invests alongside others in disruptive start-ups across a variety of sectors, including the online estate agency Strike, and food brands Five Guys and Chicken Shop.

In 2012, Sir Charles Dunstone received a Knighthood for services to the telecommunications industry and his charitable work. In 2015 he was appointed Commander of the Royal Victorian Order (CVO) for his work with The Prince’s Trust. Charles' charitable trust, the Dunstone Educational Trust, is the main sponsor of the Fulwood Academy school in Preston, Lancashire.

Tristia is an Independent Non-Executive Director at Next Plc, the Trustee Chair of homelessness charity Crisis, and an Honorary Trustee for the national charity Ambitious about Autism. She’s also a member of the CEO board and a founding member of the industry campaign against online harm known as Internet Matters.
