No i don't think they'll be ok you switching multiple times, I'm fairly sure if you switch away within a certain time period the bank claws back (some of) the fee they paid the broker. If that's what you're planning to do, don't use a broker.Would the brokers who don’t do fees be ok with a plan to switch several times? Or would it leave them having to sort out claw backs before the final mortgage provider? Or would they get sign on rewards and be winners too?
