According to The Guardian:
Kemi Badenoch is considering changing the Equality Act to allow organisations to bar trans women from single-sex spaces and events, including hospital wards and sports.
The change by the equalities secretary would redefine sex in the 2010 act to specifically refer to legal protections for “biological sex” – the sex assigned at birth.
Badenoch asked the Equality and Human Rights Commission (EHRC) to advise on the change, it emerged on Tuesday. The equalities watchdog said the new definition would make it possible to exclude trans people from same-sex spaces even if they hold a gender recognition certificate (GRC).

The Guardian fails to mention the extent to which exemptions already allow for single-sex provision, regardless of possession of a GRC. But it looks like a step in the right direction is in the offing, and the EHRC's position looks promising.
Sex Matters said:
This is a measured and thoughtful analysis from the EHRC. We are confident that our proposed amendment will deliver substantial improvements in clarity and fairness, but for now we are content with the conclusion that it merits further consideration.
