Can I just turn up?

We strongly recommend pre-booking your swim session in advance through the Better UK app or website. Outdoor pools often reach full capacity, and booking ahead helps ensure you get a space. Walk-in bookings may be available on the day, but only if the session isn’t already full. If a session is showing as Fully Booked online, walk-ins will not be available unless there’s a late cancellation.

West Reservoir Centre
Sessions at West Reservoir are intended for experienced open water swimmers only. If you're new to open water swimming, we strongly advise not to attend without proper supervision and guidance. Before planning a visit, please review Swim England’s open water safety advice to ensure you’re prepared: https://www.swimming.org/openwater

Jesus Green Lido
Yes, you can just turn up and wherever we have space we will do our best to allow entry. Please note: We highly recommend booking and queues can be long on hot days so it is always advisable to check on the App or website first. If no sessions are showing, then the likelihood is we are at capacity which means no walk-ins.

Oasis Sports Centre
Walk-in sessions may be available on the day but space is limited. You're strongly advised to pre-book swim sessions as they can get very busy.

Hillingdon Sports & Leisure Complex
Yes, but to avoid disappointment we advise you pre-book your swimming sessions.

Charlton Lido and Lifestyle Club
During the busy summer months (June–September), we operate a booking system to ensure everyone gets the chance to enjoy the pool. Sessions must be pre-booked in advance as capacity is limited and the pool can get extremely busy—so book early to avoid disappointment!

Reserve your timeslot online or via the Better UK app, selecting Charlton Lido as your preferred club.

Walk-in sessions are subject to availability, so to guarantee your swim, we strongly recommend booking ahead.

Woodstock Open Air Pool
Walk-ins may be available but to avoid disappointment we advise you to pre-book swim sessions at Woodstock Open Air Pool.
