Money MoT: Platinum Monthly Saver Cheshire, Derbyshire and Dunfermline Building Societies have launched new issues of their Platinum Monthly Saver accounts paying 4pc. The account is fixed until April 30, 2014, however, the Dunfermline version is fixed for 12 months from opening. The accounts can be opened in branch only and monthly deposits of between £100 and £500 are required. Savers investing a lump sum are having to scour the markets to find the best interest rates on offer for their hard earned cash. For those who do have a lump sum to invest but also have additional forms of disposable income, a regular savings account can form an important part of an overall savings plan. Rates may look better but savers must make sure that they can commit to a regular deposit. "With this change, these providers, all part of the Nationwide group, have put their regular saver accounts in line with other providers" offerings," said Susan Hannums, spokesman at Savingschampion.co.uk. The new rate is still competitive, but better rates are on offer from the likes of Marks and Spencer (6pc) if you have, or are prepared to open a current account with them. Savers should also bear in mind that should you miss one payment or make more than one withdrawal, the rate falls to a paltry 0.5pc.
