Having just gone through the process, I can say its quite a hurdle, not so much from the council, who in my case bent over backwards to help, and neighbours but more the way the government has slipped in yet more nanny state meddling.
For example, the use of sustainable transport has to form part of the decision to grant planning, major point that, since every one I know jumps on the bus to take their dogs to the groomers, NOT!
Good luck with your new venture.
