Almost every gym in London already has a website (just 0% don't), so this is an optimisation market: audits surface slow, outdated or unconverting sites rather than missing ones.
Online booking is essentially absent here: not one of the 29 gyms we audited offers it, so they're handing after-hours bookings straight to the competitors who do. Ratings are strong (4.6★ average), so reputation isn't the lever — web presence and acquisition are.
Across the board the market scores 16/100 on our opportunity index: 0 businesses land in the high band (70+), 0 in the middle, and 29 are already in good shape. That sits 10 points below the London average, so other niches in London may convert faster. The high-band names are where a cold pitch lands easiest, because the gaps are obvious to the owner too.
