England Women lost their first game of the tournament at the hands of Ireland but ended their campaign on a high with victory over hosts Wales.
After the U16s travelled to Dublin, the U18s face Ireland, Scotland and hosts Wales in Cardiff as the England Men ensured a clean sweep and the Women earned a 2-1 record.
Lauren Milligan and Adam Davies were the respective head coaches of the women and men and the matches were an opportunity for players to stake their claims for selection for the Great Britain teams, though other English players not selected for these tournaments will also be in the running when those squads are chosen.
