After shlepping up and down for over a week, ringing plenty and getting - "cant do, wont do, no solicitors in" as a response I finally realised that the red fronted building on Borough High St was not a Designer or Consultancy but a very nice friendly efficient solicitor. No connection at all to me.
He did all my witnessing for the regulated £5 fee.
