What it costs
Pricing breakdown
| Membership | Price | What it gets you |
|---|---|---|
| Single club | £210–£287 | One named club. Wimbledon, Richmond and Clapham Junction sit at the bottom of that range; Marylebone and Mayfair at the top. |
| Multi-club | quoted on enquiry | Access across the estate, priced above the single-club rate for your home club. |
| Off-peak | discounted | Available at some clubs, typically weekday daytimes. |
| Joining fee | variable | Frequently waived during promotional windows. |
Six of the fourteen clubs we list carry published rates; the rest are our estimates and are marked Est. Third Space prices by club, so the gap between Wimbledon and Marylebone is roughly £77 a month for the same brand.
Across the 14 London Third Space venues we hold a price for, the range is £210.00 to £287.00 a month, median £257.00.

The honest view
Pros and cons
Pros
- A pool at every single London club, which no budget or mid-market chain manages
- Facilities depth is the highest in this directory — spa, clinical services, specialist studios
- Clubs are genuinely different from one another rather than a rolled-out template
- London-only, so the estate is built for London commuting patterns
Cons
- £210 to £287 a month is three times Nuffield Health and ten times The Gym Group
- No 24-hour access anywhere
- Contract terms rather than rolling months
- Central clubs are heavily used at lunchtime and after work
Not for you if: Anyone cost-conscious, anyone who trains outside staffed hours, and anyone outside the central and inner-south catchment.
