# List of British records in swimming

The British records in swimming are ratified by the United Kingdom's governing body in swimming, British Swimming. Records can be set in long course (50 metres) or short course (25 metres) swimming pools, with records currently recorded in the following events for both men and women.
* Freestyle: 50 m, 100 m, 200 m, 400 m, 800 m, 1500 m
* Backstroke: 50 m, 100 m, 200 m
* Breaststroke: 50 m, 100 m, 200 m
* Butterfly: 50 m, 100 m, 200 m
* Individual medley: 100 m (short course only), 200 m, 400 m
* Relays: 4×50 m freestyle (short course only), 4 × 100 m freestyle, 4 × 200 m freestyle, 4×50 m freestyle (short course only), 4 × 100 m medley
The relay records displayed here are the official national relay records. However, British Swimming maintains a separate set of national relay records for club teams, which are not shown here. Records can also be set at intermediate distances in an individual race and for the first leg of a relay race.
The ratification process involves the swimmer submitting an application to British Swimming, providing details such as the swimmer's name(s), time swum, date and location of the swim, names of officials, and the swimsuit model worn. Once ratified, the records appear on the official records listing. Records that have not yet been fully ratified are marked with a '#' symbol in these lists, and all records were achieved in finals unless otherwise noted.
