UK/NHS experiences of tubals?

In the current climate, there’s growing concern of SCOTUS’s decision affecting UK politics. For those wanting to find out more, describes well why it’s a real fear

I’m 23F, I’ve got good medical reasons to appeal to doctors for a tubal but it hasn’t stopped them from trying to deny me a routine keyhole surgery in the past – there was an extremely small risk of a specific complication.

I have a very strong case to be sterilised but I’m not sure it’ll make a difference at this age, so I’m asking if anyone has any advice on navigating this through the NHS?

What got me that keyhole surgery was explaining I’d foster or adopt if I ever did change my mind about kids. It’s something I’ve said to doctors for a long time when fertility has come up as I was fostered myself so I’m hoping it’ll strengthen my case alongside shitty genetics.
