You would be better off saying ok put the benefit into my pension instead.
I might have been able to get the same treatment on the NHS (this was for a running injury, so not a life-critical illness), but the doctors, MRI, and two consultants visits were done on consecutive days - i.e. within a working week I went from "ow my knee hurts" on a Monday morning to having seen a doctor, a consultant, getting an MRI, and then seeing the consultant again who prescribed a course of physiothearapy by Thursday afternoon (the physio was also booked the same day).
With the NHS it probably would have taken two or three days to call at precisely 08:30:00 to get an appointment before they book out, then I'd be waiting minimum two weeks before I even went to that first GP appointment, and I am sure their response would have been "stop running and see if it gets better in 3 months - come back if it hasn't. NEXT." (based on experience)
Seems like a good deal to me.
I certainly got no value from BUPA when I had major transplant operation - just a £500 tax bill.
Almsot 200 EUR a month on dental seems outrageously expensive.
Getting a simple figure on the prices is difficult but it seems like the going-rate is appox £16-21 pm (lets say 20-30 EUR): https://www.moneysavingexpert.com/insurance/dental-insurance...
The amount I have to decalre to the tax man for the "benefit in kind" value my health insurance through work (which is private health & dental for me, my spouse, and all dependants - includes private GP appointments, physio etc etc) is about £1600 for the entire year, or £~135/month or ~155EUR/month. I apprecaite that is just from my P11D form [1], but there are some other sources that are in the same ballpark: https://www.moneysavingexpert.com/insurance/cheap-health-ins...
