Jennie Bond claims she is good with her money and with good reason.

The former royal correspondent and runner-up on I'm a Celebrity... Get Me Out of Here! not only saves much of her hard-earned cash but she pays off her credit cards in full each month. Perhaps the praise should go to her husband Jim who is her PA and sorts out her finances.

Nevertheless, Martin is an expert at finding ways for even the most efficient saver to bank even more of their money.

And that’s exactly what he did as he reckons Jennie could still save herself just over £1,000 a year even though her finances are already well in order.

The bulk of that saving could come from changing her credit card. She currently spends around £3,000 a month on her Barclaycard and pays it off in full each month.

If she switched to a Capital One Cashback card she would be paid 4% of what she spent in her first three months and then 1% after that. That’s an initial £4 she’d earn for every £100 spent. Over a year that could net her £650.

She could also save another £150 by switching bank accounts. She has a standard Barclays account which only pays her 0.1% interest on her in-credit balance, but switch to Abbey and she’d get 8% in the first year on balances up to £2,500.

Jennie could also switch home phone provider to save another £240 as she’s been loyal to BT for too long.
