Other experiences?
When a given case was going to take more time than I had, I would refer them to Bates Wells or Cameron McKinna or the Rights Partnership or DJ Webb or Devinshires. Plus about a dozen or so small 'specialty' firms for things like nannies, OTR dependents, unmarried partners who are still legally married, the filthy rich, and so on.
Never had a complaint. But you have to remember that when you go to a bang-up name, there's a bang-up price tag attached. A straight-forward application can run about 5,000 pounds or more, and that's not crazy because I've seen it enough times first hand.
Like John says, for a T1 General, if you think you qualify, then it's not necessary to go kicking in doors on Chancery Lane; if you need help, then Vicky's fine also (especially if you get the UKY discount). Fair rates. It all depends upon how confident you are about the application...
