Government Guidelines have stated the following for all leisure clubs in relation to the introduction of Digital Certs for gyms and leisure centres;
  • All members using gym, studio and fitness classes will have to produce their digital cert for entry. This will be mandatory for all members. Face masks will also be required for members entering and leaving the facility.
  • Swimming Pool only members will be able to use the facility without producing a Covid 19 Digital Cert but won't be able to participate in Fitness Classes or Aqua Aerobics.
Members will be asked to leave if they don't provide a Valid Digital Cert. This will be in place from December 7th to January 9th.
