There's a warning for savers who's fixed term deals are coming to an end - don't take your eye off the ball now or risk having your returns wiped out in a matter of months. A year ago, there was a flurry of savers choosing fixed-rate bonds as they improved drastically. But if you don't act, the chances are it'll rollover into an awful rate.

Also on the savings front, NS&I reveals the rate of the new British Savings Bond - is it worth it? And an Isa millionaire reveals all to This is Money on how he built up a seven-figure pot. Helen tackles another reader problem – this time, it's a case of the unwanted and unneeded Sim card costing a pensioner couple hundreds of pounds. And on the utilities front, Lee reveals how Ofcom saved him from a 75 per cent rise in his monthly broadband costs, and why you should check if you're out of contract with your mobile phone. Mortgage approvals are up - but house prices nudge lower. What's going on?  Meanwhile, research shows a record third of all homes are being bought by first time buyers – and they make up 89 per cent of buyers in one Berkshire town.
