I think it is very easy to switch if you close your old account and just transfer everything to Santander as they will then do it for you.
I chose to keep my old account open (being a cynical person) and just transferred to Santander the direct debits that would give me cashback. This meant that I had to change the direct debits and pensions myself but that was not too difficult.
Heatwave now, but what’s the betting…?
