Bollinge, you really should desist from saying this as it simply isn't true. I have done some checking, and as far as I can see few private consultants offer template biopsy as the default, mainly because the general anaesthetic is rather expensive (anaesthetist, theatre time, bloods, recovery room charges, etc) and rather more risky. Men who are insured may have differing experiences of persuading their insurer to pay the additional costs, and men who are self financing because they are frightened may find the TRUS biopsy affordable and the template biopsy unattainable.
All you are doing is causing additional and unnecessary fear / anxiety. The material removed during the TURP will probably have been far more substantial than any biopsy, template or otherwise. So a clear TURP, a clear MRI (presumably mpMRI since it was done pre-consideration of biopsy), symptoms that are indicative of urine infection, prostatitis or anxiety rather than PCa, a PSA that fell significantly with the removal of some excess gland material and has held stable since plus what I assume is a large prostate (otherwise he wouldn't have needed the TURP) .... Unless the pathology from the TURP showed pre-cancerous changes, PIN or similar, what makes a template biopsy worth the risk?
