I have sent an email to the manager of the Bethnal Green Branch, Michael, to cancel my membership and he refused to do it. He said I need to either for in person or send it to the general email address.
Please be aware of the dodgy behaviour this chain has. If you look at other negative reviews you will see that they find every possible excuse to avoid cancelling your membership.

If I am reaching out to the branch manager I simply do not understand why he cannot process my cancellation or forward it to the relevant internal team / general email address to process it.

Also, the gym is a mess. I definitely will not recommend it; it's affordable but definitely one of the worst gyms I've been in London. Equipment does not receive proper maintenance and the gym is always untidy making it really hard to find the necessary weights / equipment.

The worst thing at this gym is the staff. Before the gym was made 24/7, the staff was never on time to open the gym at 6:30am as advertised on their website. People had to wait outside I the cold sometimes by more than 20 min - a real shame.

They should start looking after their customers a bit more now that PureGym opened just around the corner from Energie Fitness Bethnal Green.
