I have a Simply Health policy that covers the family. Much cheaper than BUPA as it just gives back a percentage of what you pay depending on what the Premium is. It covers Dental and Optical as well.
In most cases you'll go back and use the NHS facilities anyway as BUPA just cherry pick the profitable sidelines of Healthcare. If you want to be bumped up the list for an operation, pay for an initial Private Consultation on referral from your GP.
