The notice period required to cancel a David Lloyd membership will depend on the specific terms outlined in your agreement with the club. Generally, most David Lloyd clubs require members to provide at least one full calendar month's notice before canceling their membership. This means that if you wish to end your David Lloyd membership on, for example, June 30th, you would typically have needed to notify them by the end of May at the latest. It is vital to review your particular membership contract carefully as there might be additional details or contingencies associated with cancellations based on different circumstances like relocation or medical reasons. Contacting David Lloyd directly or referring to their official website should provide you with accurate information regarding the notice period required for cancellation purposes.
