The championships did not include the non-Olympic 50 metre sprint events (but included Olympic 50 metre freestyles), and also fully integrated the British Para Swimming Championships in mixed classifications for the first times, with para-swimmers seeking nomination times for the Paralympic Games, although there are no automatic or guaranteed berths.

The following para-swimmers gained a nomination time in these events:[27]
