Might be better to find out whether you have a centre of excellence near you - don't assume that going to London will get you the best treatment. Also, there is no research to say that robotic is better than laparoscopic or open RP; in some cases (depending on where the cancer is locally advanced to) open is the best option for T3. In other cases, surgery isn't even offered to T3 patients if it is suspected that the cancer can't all be removed successfully.
My husband had open RP because a) he had a suspect lymph node that could not be removed by keyhole b) the surgeon felt that in this case 'getting his hands in' would give the best chance of recovering erections afterwards and c) he had his appendix removed years ago and the scar tissue was in the way.
Open and LRP/da Vinci all have the same success rates in terms of positive margins, recurrence at 5 years, remission at 10 years. Permanent incontinence and serious ED are slightly less likely with open. The advantage of LRP / da Vinci is shorter inpatient stay and less time off work.

I guess you are thinking, oh my God, T3 Gleason 7, but don't worry yourself too much.
You have plenty of time to consider all options, my advice is to spend a few weeks learning as much as you can, learning as much as you feel you need to know, so that you can make an informed choice about which of the various treatment options you prefer.
I was diagnosed T3 Gleason 9 back in 2007 and I am still here doing just fine.
I had my open rp in Reading (private) a year ago (couldn't have robotic due to previous stomach surgeries) after being diagnosed with Gleason 7 T3a PSA 49. I'm doing fine now and have 4 consecutive 0.01PSA behind me. No regrets about any of the decisions I made. All the best.
I had robotic Jan 4 this year with nerve sparing. My gleeson was 3+4 and after pathology it was T3 and after eight weeks my psa is 0.1 so I may end up getting zapped at some time but I'm continent and my Gentleman's sausage is coming back.
I asked the surgeon how many he'd done and he'd done 70+ last year alone and he was very experienced with open and keyhole and I found his profile on the net .
Had catheter out after two weeks and I actually started doing a few small jobs after three and the seven cuts across my big belly as the surgeon called it (he isn't wrong) healed up quickly .
I had my op at Leicester General hospital and considering these tough times in the NHS my experience was excellent and I've never had an operation before
