Employer has asked me to use the disabled toilets following the supreme court ruling. Is this even legal?

During a 1 to 1 today my boss asked me what toilets I’d been using since coming out.

She helped me with the whole process and said I can use the bathroom which I align with. I checked with a member of the pride group at work and she showed me the legislation and it’s all good. About 2 months go by and during this one to one she said if I could use the disabled toilet. This was because she didn’t want me to be uncomfortable or anyone else and the supreme court ruling and ‘stuff’ just absolute rambling.

I said sure but immediately emailed HR asking for the new policy since I’d seen one a few months ago be fully supporting. I thought the interim guidance from the EHRC was not law and that companies don’t need to act on it. She might be covering up for a complaint however I feel like that’s less likely.

I’m awaiting my response from HR however there’s only 1 disabled toilet in my office of over 100 people which is in the men’s section. It’s currently out of use though so I have to walk to a different building which has 1 for another hundred people. If that’s not free I have to walk another 10 mins to the other side of my site. I mentioned this in the email and asked if this would be taken into account.

I have ibs so I have to run to the bathroom even if I’m looking after myself. I might miss meetings or be late so I don’t want this to affect my performance.
