Several times recently I've used the Best Buy section in the Sunday Times 'Money' section, only to find the information inaccurate. The latest: 'The Best Cash ISAs' shows Skipton BS offering 4.50% for a 3-year fixed rate ISA. But a check on the web page (and confirmed by phone) shows that it's a 5 year rate.
Looks like these tables are not constructed with much care IMO.
