Is it a good practice to keep salary account and savings account separate?
There is no "should", but I am strongly of the view that if you have savings of several months' salary or more, they should not only be in a separate account, but with a separate financial institution, or even split between two others. A fraction of a percent of extra interest is scant reward for massively increased personal risk.  The reason for this is buried in the T&Cs. There is almost always a "right of set off": if one account is overdrawn, the bank reserves the right to take money from your other accounts. Which sounds fair enough, until you consider the imbalance of power. Maybe your salary account gets hacked? Maybe that's the bank's fault? Maybe the bank has made an accounting error? Maybe the bank has gone bust? Maybe you need to employ a lawyer to act on your behalf? Oh dear, you no longer have any savings. (*) This cannot happen if your savings are with a completely separate institution. Then, the only way that the salary account bank can touch your savings is by winning in the courts. If you split the savings two ways, you have also given yourself the reassurance that in the worst case only half your savings have been affected. "Don't put all your eggs in one basket" is proverbial. And there's a folk song that's lodged in my memory...  "As through this world I wander, I've met all kinds of funny men. Some rob you with a six-gun, some with a fountain pen. Yet as far as I have wandered, as far as I have roamed, I've never seen an outlaw drive a family from their home".  I've never been in this sort of trouble and the UK's laws tend to favour the banks' customers. I don't even hate bankers. Yet even so, why take this risk when it can so easily be reduced?
