A Swim-Meet module costs a single organisation (club, county or region) £79 / year for unlimited meets. Each subsequent module taken out costs £40 / year.
There are discounts for taking out a licence for multiple clubs. For example, a county may take out a licence for £300 / year and then the county and all the clubs within the county may use the module for their own meets.
Each subsequent module on a county wide licence costs £80 / year
