Update 14 August 2018: Martin wrote this blog back in 2013 but while the rates have changed, all the logic is still correct.

I couldn’t believe my ears. While filming in southern Spain for the new series of my show, the producer told me he’d found a cash machine offering 0% commission if you chose to withdraw in pounds. In theory, that’d mean PERFECT exchange rates.

The pound is still in the doldrums. A few years ago, before the EU referendum vote, a pound bought €1.43 – since it's dropped significantly and hasn’t recovered much. Last summer it bought €1.14, and today it’s hovering around the €1.12 mark. Against the dollar, the rate is just $1.32 – about a decade ago it bought roughly $2. It’s similar with most other currencies.

You meet someone, fall in love, and hearts pop out of the sky when you look at them. They’re the person you want to spend the rest of your life with. But is there any point in actually being married?

Refund, refund, refund, (refund, refund). No I’m not stuck on repeat, I’m trying to hammer home that people are owed hundreds of millions of pounds that they’re just not claiming – most of which can be done with a quick click or phone call. Here’s what you need to do…

On 6 April, most UK workers aged 22 or over are due a hidden pay rise – but your employer doesn’t need to tell you. This is all about the ‘auto-enrolment’ scheme – where your employer has to contribute towards your pension, and now it’s going to have to give you even more. So I wanted to...

I don’t do adverts. If you ever see one with my face or name on it, it is without my permission, and usually a scam. Admittedly some are supposedly legit firms bending the rules to imply a link (though do you really trust firms that’d do that anyway?). The latest Facebook ad plague with me in is...

Update Wed 14 Mar – childcare voucher deadline extended. Parliament has just voted to extend the deadline for joining the Childcare Vouchers scheme by around six months (no final end date is confirmed). It’s still worth following the logic of the original info below to decide which scheme is best for you though (but I haven’t updated it...

British Gas is the UK’s biggest energy firm, and millions of customers stick with it through thick and thin, even if they know they can get much cheaper deals elsewhere (as I constantly nag about). Yet right now there’s a route that enables existing British Gas direct debit customers, who use dual fuel (ie, gas & electricity)...

For those saving for a first-time residential property, Help to Buy ISAs and Lifetime ISAs are no-brainers, as an unbeatable 25% bonus is added as well as interest. In other words you get an extra £250 per £1,000 saved towards any mortgage. Yet as you can only get the home-buying bonus on one of them, you need to pick which is...

Bitcoin, the cryptocurrency, continues to smash through price barriers, with one Bitcoin this week breaking through the $11,000 mark (then back to $9,000, then who knows what by the time you read this). Some early adopters have made millions and Facebook is now full of adverts to tempt the public to invest their hard-squirrelled cash in it.
