The 2024 Aquatics GB Swimming Championships (sponsored by Speedo) were held at the London Aquatics Centre in London, from 3 April to 8 April 2024. They also doubled as the trials for the 2024 Summer Olympics.^[1] They were organised by Aquatics GB, formerly British Swimming and was the first time the event had been held under the new name.^[2]

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.

Para swimming races have been folded into the Championships as a series of multi-classification events, and these events act as partial qualifiers for the 2024 Summer Paralympics. Unlike the able-bodied events, a different system means no guaranteed places are created, but a swimmer wishing to be considered needs to meet a qualification time known as a 'nomination time', calculated on a points basis within their classification.

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