Martin Lewis has warned viewers that a ‘nasty, worrying’ rumour may be ‘possibly accurate’.

The Money Saving Expert issued the warning ahead of a Black Friday and Christmas special of The Martin Lewis Money Show on ITV tonight.

Taking to Twitter, Mr Lewis said: “PS rumours I may be doing another singing introduction to tomorrow’s The Martin Lewis Money Show Christmas (prep) special are nasty, worrying, and possibly accurate”.

The tweet received many joking responses, with one user saying: “Only fair you tell us where we can get cut price ear plugs then!”

While another added: “Note to self, start watching the show five minutes after it starts”.

Martin Lewis “no-brainer” energy saving tip

Speaking on last week’s show, Mr Lewis urged Brits to check the “flow temperature” of their boiler.

The flow temperature – the temperature your boiler will heat up water before sending to radiators – should be set at 60 degrees but many are programmed much higher than this, the cash-saving guru explained.

He said: “You normally want it to be around 60° but most peoples boilers are set higher - that’s really inefficient.

“You can turn this down, it won’t affect the heat in your house, it’ll still be the same temperature.

“It won’t affect your hot water temperature - it might take slightly longer to get up to the maximum temperature.

“But it can cut £100 a year off your bill and is well worth everyone doing.”

He added: “This is an absolute no-brainer and everyone with a combi boiler should be trying this.”

Martin recommended using the free MoneySavingBoilerChallenge.com website if you are unsure how to check your flow temperature.
