Club records have been maintained continuously since 1968, with some records going back to 1964.
Records for some events have only recently been recorded, notably
- 400 m and 800 m freestyle for age divisions since 2005/2006
- 1500 m freestyle for age divisions since 2007/2008
- 100 m individual medley (all ages including open) since 2010/11
- 400 m individual medley (all ages including open) since 2013/14
Age group records are inclusive, in that a swimmer could break a record not only for his/her current age group, but also for higher age divisions as well. Prior to the 1979/1980 season, swim times were only measured and recorded to one decimal place. Prior to 2012, three times had to be recorded before a record could be acknowledged, with the middle time being the record time. Since 2011/12 and the introduction of electronic stop watches, only two times have to be recorded, with the greater time being the record time.
The Club Age Championships were re-introduced in the 2012/13 season and records have been maintained since then. Club Age Championship records are exclusive: a swimmer can only break a record for his/her current age division.
