I run the UK’s biggest bank, here are five ways to manage your money.

Nunn says the key to building savings is automating putting money aside.

This means regular saving stops being a decision or action you have to take – and stop.

“I think that’s the easiest way to start a frugal mindset if you can scrape a little bit out and put it somewhere else that you can’t reach and spend it,” he says.

This could mean setting up a direct debit from your current account to a savings account, organizing money into different envelopes, or using tools that keep change aside when you go out.

“Save a little, save early and save regularly,” Nunn advises.

He admits that he “hates budgeting and always has,” so as soon as he gets paid, he looks at his current account and decides how much he wants to put into savings. “Do it as fast as you can,” he added.

As well as savings, he recommends having an emergency fund for unexpected bills like a broken boiler or car repairs. How much you need in the money depends on your situation, but if you can, he recommends setting aside one to three months’ salary.
