Savings Guru Verdict

Castle Trust launched with a range of fixed rate savings and quickly added fixed rate ISAs to its range.  Although many of its best rates are for existing customers only, its 1 and 2 Year Fixed ISAs were best buys when they launched in September 2021.  We expect Castle Trust to continue to expand its savings range as the bank develops.  It's initial customer service feedback ratings are patchy but we have found them very efficient to deal with.
