The qualification window for the 2025 Aquatics GB Next Gen Championships and GoCardless Swim England National Summer Meet has opened.
It runs from Friday 7 March and through to Sunday 11 May.
Selection for the summer competitions are by invitation only based on long course times achieved during the window.
The 2025 season will see a change in the number of swimmers offered the opportunity to compete in the Aquatics GB Next Gen Championships based on data and evaluation from previous summer competitions.
In the 13-14 year age group, the 20 top-ranked swimmers in each group will be invited to compete.
The 24 top-ranked swimmers in each event in the 15, 16, 17 and 18-year-old age groups will also be invited.
In the 19 years and over age group, the 20 top-ranked swimmers will be invited to attend.
The only exceptions to these numbers are the 800m and 1500m Freestyle events, where the top 18 swimmers will be invited in all but the 19+ age group, where 16 swimmers will be invited.
The Aquatics GB Next Gen Championships take place at Sheffield’s Ponds Forge International Sports Centre from Saturday 19 to Friday 25 July, with the same venue hosting the GoCardless Swim England National Summer Meet between Tuesday 29 July and Sunday 3 August.
