Press and data
What Gyms Cost is an independent record of what London gyms cost. Every price is read from the operator's own public website and re-checked nightly: 648 gyms, 517 with a published price, across 33 boroughs. Nothing is estimated. Checked 30 August 2026.
The figures, as of 30 August 2026
| Median all-in monthly membership | £44 | across 517 London gyms that publish a price |
|---|---|---|
| Mean all-in monthly membership | £84.76 | 93% above the median — the London market is split, not centred |
| Dearest borough | £161.38 (Kensington and Chelsea) | against £30.24 in Harrow — 5.3x |
| Charge a fee on top of the advertised rate | 56% | 290 of 517 priced gyms carry a joining, admin or annual fee |

Why the average is the wrong number
Almost every published figure for London gym prices is a mean, and a mean is misleading here, because London is not one market. Of the 517 gyms that publish a price, 60% are under £50 a month and 27% are over £100 — but only 12% sit between the two. The middle of this market is close to empty, so the mean of £84.76 lands in the gap and describes almost nobody.
The median of £44 is the figure to quote. The shape is the story: a quarter of London's gyms are under £34.24 and a tenth are over £225.

What we can help with
We can produce a borough-level, brand-level or station-level cut of the data for a story, usually within a day, and we do not charge for it. We will also say plainly when the data cannot support a claim — 131 London gyms publish no price at all, and we never estimate one.
How to describe us
What Gyms Cost is an independent price record for London's gyms. It takes no payment for ranking or placement, and the ordering on every page is the data's, not a customer's.
