LOOKING TO GET IN TOUCH WITH THE CASTLE GYM TEAM?

Founding Members are the first group of individuals to join our new city centre super gym. This status is permanent (whilst you remain a member) and carries exclusive benefits, including a limited-edition physical Founders Card, a luxury merchandise box, and a lifetime of £0 joining fees should you ever need to reactivate.

Our Founding Member sale is running throughout January 2026. People who sign up during this sale will not pay a joining fee and will receive exclusive perks.

Your first membership payment secures your Founding Member status. Regular monthly billing cycles will then commence the month after our opening in March as you have secured your first month payment for February. Non-founding member/regular sign ups from February onwards will be billed as standard on a monthly basis, or annual depending on your membership type.
