We currently have Aviva through work. I have gone for the top of the range version, some £250 as benefit for tax and a £150 per person per year excess.
DH has made a lot of use of it. Work negotiated that existing conditions are not excluded. Not sure you would get that on a personal policy.
The work supplied one has changed over the years, they have all been good.
The only things DH has been refused cover for has been for monitoring of chronic conditions. They only cover consultations to investigate new symptoms, which seems fair enough
The only part we do not use is the option to use a private GP, which would mean that our records are transferred out of the local NHS surgery.
I'm due to retire in the next ten years, and the local NHS GP's surgery is pretty good. Their list id now closed so if we transferred out, we might not get back when I retire and we no longer have private cover.
It is extortionate as a pensioner / over 75. My parents resigned themselves to just pay in retirement. Don't think we can afford that for DH's usage level so I shall probably work til he drops 😀
Once you get used to not having to 'queue' for treatment, it's very difficult to go back. I'd encourage anyone who can afford it to have private insurance. I really wish we all did through the European model of nationally controlled medical insurance rather than the free for all that is the USA, where if you can afford it it's wonderful and if you can't, it's bad luck.
I think the European model of personal health insurance through your employer, with a safety net for pensioners and the unemployed is a better way forward.
