Martin Lewis, 45, appeared on Good Morning Britain today and warned viewers to look out for Facebook Bitcoin scams involving his name.
The money saving expert has been plagued by fake scams in the past, and has now had to speak out about another.
He said: “There’s another plague of Facebook ads with me in – the ‘Bitcoin Code’ or ‘Bitcoin Trader’ scam, which lies saying I suggest investing in it.
“In fact they’re not even about Bitcoin but about binary trading, something no one should touch with a bargepole.
“Sadly I’ve already heard of people who’ve lost over £20,000 saying: ‘I only pursued it because I thought it was recommended by Martin.’ The thought of that makes me feel physically sick.
“So let me be very plain, 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?). Yet beware.”
Martin then moved on to deals of the week, and with Mother’s Day coming up, revealed how to take your mum out for a free meal.
He shared: “There are a raft of fixed mother’s day menus, which aren’t that cheap, and there aren’t any 2for1 deals out there.
“Of the better offers out there if you register and download a voucher online at Frankie and Benny’s when you buy one main meal (costs around £15ish) you get one free for mum on Mother’s Day only at any time.
“Also download the free Harvester app and there’s a voucher on it to claim a free meal for mums after 6pm on Mother’s Day when you buy a main.
“Or mums can get a free glass of Prosecco (normally up to £6ish) when they order any main meal at most Café Rouge restaurants from midday on Mother’s Day. It’s likely to be busy, so it’s best to book in advance.”
Martin also explained how to save £300 or more a year on energy bills.
He said: “The best thing to do is a whole market comparison using Martin’s Cheap Energy Club or any Ofgem-approved site to find the cheapest deals on the market – your winner will depend on where you live and what you use.
“Benchmark against the average Big 6 standard tariff, costing £1,136/yr for typical use, then use the filters to narrow your search; the cheapest deal on the market on the same usage is just £807/year.”
If you’re scared of switching or of moving to a smaller cheap provider you’ve not heard of, or if there’s no feedback, then there are a couple of decent tariffs that’ll still save you, just not as much, said Martin.
