Once you have found out how much the premiums cost, then you could always save the amount each month for yourself.
At 65, I cancelled my private healthcare as the only way to contain the increases, was to volunteer higher excess payments and reduce benefit amounts.
In the past 3 years I have only made one "claim" which was for two consultations, one course of treatment and an MRI scan. The total was £750.00. Had I been insured, I would have paid out 36 premiums and a further £300.00 towards the bill. As it stands, my own "medical fund" retains a healthy balance.
I also changed my bank account to one which provided worldwide travel cover as I go abroad at least twice a year on holiday. The cost of this is significantly less than policies offered by other providers/travel companies/agents etc.
Sometimes it comes down to your attitude to "risk".
