I'm confused by your posts @Humminngbirrd
I completely agree with you, by the way, that the NHS is very slow and treatment can be delayed.
But I'm not sure if you are fully aware of how insurance works? Maybe I've misunderstood your posts, so apologies if that's the case!
You say you want more preventative care and screenings etc.
I told myself I would feel better getting private health insurance after 45 since i’m getting older and I wanted to start looking at more preventative care (regular cancer screenings, etc).
This is not available on insurance unless you have symptoms. You can get private screening through a referral to a consultant (if they think you need it) if you have symptoms. BUT it has to be kicked-off by a GP referral if the insurance is going to cover it.
You can self-refer for many types of screening or appointments (with a consultant) without a GP referral but you would self-fund them.
You can also pay (self-fund) for any treatment (surgery etc) at a private hospital. Most of them publish the cost of common operations on their websites.
What sort of screening are you thinking it might cover, if you are happy to carry on with the NHS for smears and mammograms?
The BUPA menopause cover is £250 (so I've read.) It covers an appt or two with a private GP (usually remote) and any prescriptions needed. These may be paid for at cost, or the NHS may pick up the cost if the private GP writes to your NHS GP. The £250 is annual. It's like a helpline, with meds provided if you need them.
It won't cover investigations or any surgery needed.
