To be fair this conversation has gone off piste it seems. The OP's initial issues was around the Bank's not being upfront with the customer and being led on it seems. When the OP picked up the phone to the Bank they should have asked he or she the question and declined them then and there as opposed to doing credit checks etc. Perhaps they should have stated we are happy to underwrite you but you are not getting cashback? This thread is or has turned into a witch hunt IMO again switchers and there are a lot of valid points on both sides of the argument.
It works both ways. The bank have given approval in principle based on a set of circumstances or details given by the borrower for a loan. The bank has approved this switch or loan based on this information.
The applicant has then gone and switched to bank X and subsequently to bank z before coming back to switch to this bank. The material facts are not being provided to the bank and implies that the applicant knows or is aware that what they are doing is inherently wrong and while I wouldn't call it fraud, I would call it deceiving behaviour.
It the applicant disputes this then why not tell the bank he has switched twice in the previous three or four months since he got the approval in principle from them?!
If this was insurance, the policy would be null and void based on the behaviour of the applicant in question. He has not disclosed full information to the provider and thus hasbreached the terms of the transaction.
Why doesn't the applicant switch for 12 months to bank A and fix for 1 year. Then move for another cashback if that's his flavour thereafter and fix for another 1 year.
For the applicant to come on here saying that the bank should be pulled for wasting his time is bonkers. Are the banks meant to legislate and try to cover all eventualities for such 'behaviour' as his?
By all means, roll the dice and see if u can get 4 or 5 switches done in 6 months. If that's your flavour, good luck. But don't cry foul if the bank have wasted a fraction of your time compared to the amount of their time and money you have wasted.
Btw, I don't work for a bank and have availed of a cashback before where I took out a multi-year fixed mortgage. If cashback is there again when it's financially advantageous for me to break the fixed contract, pay penalty etc, then yes I will do so. Equally, I may wait til the fixed period ends and then determine which is the better option for me to take, cashback or lowest rate.
To believe switching three, four or five times in six months isn't going to have consequences with banks over the next 30+ years of your life if you are looking for a loan, remortgage, etc is a tad naive wouldn't you say?! One search and any bank will have the full SP on you and your past behaviour and will treat you in the same manner that you have treated them. You may find yourself a not very appealing customer to take on. And rightly so
