Many thanks to all. Apologies in delay in acknowledging answers, problems at this end.
I knew I was paying privately for the bridges and implants, cost many, many thousands, but I originally registered as NHS when I joined the practice five years ago, and should still be on that footing.
I have to pay £50+ for the hygienist so that is obviously private, but my six months check up should be NHS rates. Will phone them on Monday. Thanks again everyone.
