Ultimate flexibility
The Flex Space is available from 06:00-21:00 on weekdays and 09:00-13:00 on weekends, bookable in one hour slots.

— Book in only for the times that you need for your clients’ training sessions via our online booking system.
— You pay only for the hours you use – there are no upfront, administration or membership fees.
— You make all arrangements for payment with your client – we take no commission.
— Slots are bookable hourly at the top of the hour or at half past the hour.
All packs have an expiry in weeks corresponding to the size of the pack. A 5 pack has a 5 week expiry, a 10 pack 10 week expiry and a 20 pack carries a 20 week expiry from purchase. Packs also have a discount corresponding to their size, so a 10 pack has a 10% discount and so forth. Packs can be used for multiple clients, there is no limit on the amount of clients you can bring per pack.

A £2.50 charge will be made in respect of any cancellation within 12 hours of the booking. No shows incur a £5.00 charge. There are no refunds.

Sessions on the app appear to be half hour in length but are in fact one hour. So a 6:00-6:30 booking is in fact 6:00-7:00.
