Title-rivals and reigning champions, Cardiff Met had won in midweek to set up a last-day decider but it was City who held the advantage with a significantly better goal-difference, meaning they only had to match the students' result.
Cardiff Met made sure City had to win, as they built an 8-1 winning margin against Llandudno Junction. Emily Brown, Jaz Thomas and Emily Allen all scored in each half goals, Dana Hinton and Steph Turner also on target, while Sophie Owen got Junction's consolation.
Rachel Rowe and a Danielle Broadhurst double had the leaders three goals to the good by the break and although Wrexham's Lowri Edwards replied, Alicia Davies quickly restored the three-goal cushion to calm any nerves. Katie Edwards did pull a second goal-back for the visitors but Davies was again on target as City ran out 5-2 winners and celebrated their first ever Welsh Premier League title.
Aberystwyth Town won 4-1 at Caernarfon Town to consign their hosts to a last-place finish. Claire Thomas and an Anna Jones own-goal had Aber 2-0 up at half time. Kelly Thomas got the third, Katie Bowe replied before Mel Davies wrapped up the scoring as Aberystywth ended the season goal-difference behind sixth-placed Port Talbot Town.
