Billericay Town In November 2016, a Tamplin-led consortium had withdrawn their bid to take over
Dagenham & Redbridge, after the board of directors removed their support for the offer. In December 2016, Tamplin purchased
non-league football team
Billericay Town; the initial acquisition which was widely reported was followed by the signings of former star professionals
Paul Konchesky,
Jamie O'Hara and
Jermaine Pennant. Tamplin invested over £2,000,000 in the club for improvements and a new pitch. Tamplin showed the unique murals and changes of the changing rooms to
Sky Sports, along with match rituals. In the 2017–18 season, Tamplin assumed the manager's position at the club and guided them to the first round of the
FA Cup. However, he rehired himself just two days later. On 4 April, for the second time in two months, Tamplin announced via an interview on
YouTube, entitled "Understanding me – Glenn Tamplin", that he would again resign his post as manager. On 2 September, Tamplin released a statement via the official Billericay Town website that the club were now up for sale, citing two incidents where he was reported to police for alleged drug abuse (which he said were unfounded) and had led to the police questioning him about the allegations in front of members of his family. Tamplin stated that he could "take the personal abuse but now it has started to affect my health and my family. For me it has now crossed the line." On 18 September 2019, Billericay Town announced Tamplin had stepped down as owner and director of the club.
Romford In November 2019, Tamplin joined
Romford, immediately sacking manager Paul Martin and appointing himself in place. On 4 March 2021, as result of the
COVID-19 pandemic, Romford announced that Tamplin had left the club. ==Philanthropy==
