You will not get any interest worth having on an instant access account so, in my view, whichever bank and building society you know and trust should be fine. You should not take all the money out of the savings funds until the the bonds mature and/or the money will be needed.

Could anyone tell me the best account to put my moms social care money into. She is having to take it out oof bonds and trusts and presumably into an instant access account - anty suggestions?
