Central midfielder Luke Hannant joined Cambridge from Norwich's youth team aged 14. A central midfielder, he played for the CRC side in the Ridgeons League. He later joined Dereham, playing a key role as they won the Thurlow Nunn Eastern League in 2012/13.

He then headed to the North East to study Sport Science at Northumbria University. Whilst there, he began playing for Conference side Gateshead as well as Northern League side South Shields. When Gateshead manager Neil Aspin left to take charge of Port Vale in October 2017, Hannant followed for a five figure fee. He finished the 2017/18 season with 18 appearances and one goal.

Released by Port Vale at the end of the 2018/19 season, he joined Cambridge United on 28th May 2019. He had played 68 games for Vale, scoring five goals.

Hannant was in the Cambridge side that won 3-0 on 8th May 2021 to win promotion into League One having finished second in League Two. He had played 74 games for Cambridge scoring eight goals (seven of which were in the 2020/21 season)

Failing to agree a new contract with Cambridge, he switched to League Two side Colchester United on 10th June 2021 signing a two year contract. His contract with Colchester includes the option of a further year. He said "There maybe aren't many lower league players who get promotions on their CVs and people might raise their eyebrows at this move. I have to look after myself and go somewhere where I'm going to play a lot of minutes and I just wanted that new challenge."

On 31st January 2023 he joined Scottish Championship side Dundee on loan until the end of 2022/23 season.

After being released by Colchester at the end of the 2022/23 season, he rejoined Gateshead on a two year deal on 2nd August 2023.
