It's incredibly frustrating to me too.

Firstly, this is only for England. Health is devolved in Scotland, Wales, and Northern Ireland.

Preventative stuff and a lot of sexual health stuff (STD screening, free contraception) is paid for by "Public Health", which is part of local government.

Treatment is paid for by the NHS, which is sort of nationally funded by NHS England to local Clinical Commissioning Groups.

Sometimes you'll have "joint commissioning" -- for example in Gloucestershire there's joint commissioning across public health and the NHS for Mental Health.

But yes, it's stupid bureaucracy and budget holding and it's caused harm.
