I had a (UK based) AXA ppp international healthcare plan for over 25 years, only used it a few times mainly for minor dental.

It started out costing under £300 quid a year which seemed fair enough, it increased every year until three years ago they wanted over £5,000 quid to renew.

The sales agent I talked to on the phone said that the cost was so high because of the length of time I had been with them.

I cancelled.
