Our Expert Opinion on Castle Trust Bank Notice e-Saver

Castle Trust Bank's Notice e-Saver pays 4.20% and suits savers who want a better return than easy access but can plan their cash needs well in advance. The 120-day notice period is the real catch here: there are no exceptions, so if you need money in a hurry you simply cannot get it without serving the full notice. I would still check Hampshire Trust Bank's 95 Day Online Notice Tracker at 4.22% or Shawbrook's 45 Day Notice Account at 4.21%, both of which offer a shorter wait for a similar or marginally better rate. You need at least £1,000 to open this account and can hold up to £500,000.
