Club career
Arsenal
After moving away from her home in the South East, Agg joined the Arsenal W.F.C. Academy. She did manage to get into the first team squad, but made only a handful of appearances.[6] She declined the offer of a full-time contract from Arsenal, preferring to prioritise her university studies.[7]
Brighton & Hove Albion
Agg started her professional career back at her hometown club, Brighton & Hove Albion, which she had initially joined at the Under 12's level in Brighton Centre's of Excellence before moving to Arsenal.[8]
London Bees
In January 2014 Agg left Brighton & Hove Albion, in order to play at a higher level.[9] She returned to London, joining the London Bees for a short period. She scored the club's first ever goal in their 3–1 FA Women's Cup win over Leeds United.[10]
Millwall Lionesses

Return to Brighton & Hove Albion
After a two-year period away, Lily rejoined her hometown club in 2015. During this spell she helped the club gain promotion, after winning the FA Women's Premier League Championship Play Off.[12]

FFC Frankfurt
In August 2017, Agg moved to the Frauen-Bundesliga to join FFC Frankfurt, after a successful trial.[16] At the time, she was the only British player play in Germany and it was seen to be a step up in her career.[17][18] FFC Frankfurt had won seven Frauen-Bundesligas, eight German Cups and the Champions League on four occasions.[17] Agg enjoyed playing in Germany, praising the professionalism of the club and the competitiveness of the Frauen-Bundesliga.[19] In her only season in Germany, the club managed an average 6th-placed finish.

After a short stint in Germany, Agg joined Charlton for what was their inaugural season in the Championship. She made a total of six appearances and scored on two occasions on her return to English football.[20]
London City Lionesses
Agg subsequently joined Championship club London City Lionesses, ahead of the 2019–20 season. However, due to suffering a fractured tibia against Reading in a pre-season friendly, she missed the entirety of her debut season at the club.[8]
She returned to action in the 2020–21 season against Sheffield United. In total, she made eleven appearances that season, being rewarded with three player of the match awards netting her one and only goal against champions Leicester.[8]
