He won the British Home Countries Championship in 2009, and two Commonwealth Games medals in 2010 (Silver in Team and Bronze in Doubles).

[12] Pitchford represented England at the 2014 Commonwealth Games in Glasgow, winning a silver medal in the team competition as Singapore took gold in a repeat of the 2010 result.

[15] In June 2015, Pitchford was part of the Great Britain table tennis squad at the inaugural European Games in Baku, where he reached the quarter-finals.

[21] In February 2018, Pitchford was part of the England squad alongside Paul Drinkhall, Sam Walker, David McBeath and Tom Jarvis which won bronze medals by reaching the semi-finals of the ITTF Team World Cup in front of a home crowd at the Copper Box Arena in London.

[25] At the 2018 Bulgaria Open, Pitchford beat current Olympic and World champion Ma Long in the first round in a 7 set match,[26] arguably the biggest win of his career.

Pitchford began with a tense 4–2 win over Spain's Álvaro Robles and followed it up with another 4–2 victory over the evergreen Vladimir Samsonov who had just upset the fourth seed Lin Gaoyuan in the previous round.

The final against Fan Zhendong was a spectacular affair and Xiao Pang certainly had to dig deep to eventually overcome Pitchford in a nail-biting 4–2 match.

[31] At the same event, Pitchford and Paul Drinkhall reached the men's doubles final, losing to China's Ma Long and Xu Xin.

[32] In 2021, one week before the World Table Tennis inaugural event WTT Doha, Liam Pitchford suffered a minor hand injury while looping a half-long ball in practice.
