Anyone at all can complain to LGO if you have had a problem with a local authority that hasn’t been able to resolved by the complaints process of that local authority.
It doesn’t require a lawyer or cost anything except your time.
The only rule is that you have to have already been through the complaints process of the local authority first before LGO can consider your complaint.
First place to start, complain to the City of London Corporation. Unless they make a fully Supreme Court compliant response and immediately implement that at the pools, then you can refer their response and your complaint on the LGO.
I’d imagine the LGO must have been busy writing out to local authorities to remind them of their obligations to uphold the law, following the 2025 Supreme Court decision, otherwise LGO will be expecting a llllloooooootttttttt of extra work coming their way from complainants. Nobody wants that. Which is why complaining is a really effective thing to do. LGO’s decisions are published on their website so it’s a good way of bringing further attention and transparency to this issue.
The CoLC are crazy to be still clinging on to upholding their sexist misogynistic policies that have always been against the law. The fact that they disallow transmen in the men’s but do allow TRA women in the women’s pool just absolutely says it all. By their own standards they’re transphobic. Let alone not allowing self IDibg women into the men’s pool but allowing self Iding men in. But they don’t care because this is all simply about giving men what men want. They’re showing themselves to be straightforwardly illegal women- haters.
