Look up some of the earlier posts about switching that I have posted. Basically get all your paperwork in order to apply to PTSB, BOI, EBS who all offer 2% cashback and then get approval from them all. Do this all at the same time so you get approval and are ready to drawdown all loans at the same time. Apply for variable rates as it makes switching much faster and quicker. Then get your Solicitor to draw down the first new mortgage and then within 1-week drawdown the next mortgage and pay off the first one, and so on. You should get 2 % cashback from those 3 banks, so on a mortgage of 250,000 that is €5000 a time so €15,000 in cash backs in a few weeks, pay your Solicitor say €3000 and another €500 for 3 valuations and you should have €10,000 profit tax-free just from doing some paperwork. I know because I have done this a few times that yes it can get annoying with Banks looking for this or that but if you are organized and prepared to put in the work it is certainly very possible. Timing is very important and remember as far as all the Banks are concerned you are switching to them from KBC. They don't need to know that in fact, you might be with PTSB when you switch to BOI and with BOI when you switch to EBS.
