So would the best thing be to just go round all the major high street banks and see what they are offering?
Close but NO! You can check it online before you leave. You will have better things to do there than check for the best price going from branch to branch (and believe me, you might have to wait for an hour or so for an advisor to become available). You can rest assured though that as Singapore is the perfect example of a perfect competition economy, that they all charge the same. Otherwise somebody would have said already that one of them is cheapest (a very Singaporean thing

). In this case it is really just up to you to make a pick.
Unfortunately all the different ATMs are not availble across banks like the link system here in the UK. So in one corner you have UOB and OCBC, in the other corner you have DBS and POSB. As OCBC has slightly less branches than UOB or POSB I would suggest you just pick either one of the two. Flip a coin (again, you really don't want to go from branch to branch there to compare, it takes hours). You can rest assured, whichever you choose, they are all the same

.
One thing to keep in mind though, if you do have a HSBC account in the UK it is cheaper to open a HSBC account in Singapore as well as you can transfer money cheaper.
