Martin Lewis has issued an urgent warning as nearly one million people throughout the UK are failing to claim financial support worth thousands of pounds.

The Money Saving Expert (MSE) founder took to X, formerly Twitter, on Monday where he asked his many followers to "please share" his update.

He said: "PENSION CREDIT CAN BE WORTH £1,000s YET 900,000 ELIGIBLE ARE MISSING OUT. You should check if you're of State Pension age, (roughly 66+) with a low total weekly income."

He added that those who are single are "likely to get it" with a weekly income of under £238, though added it is worth checking your eligibility if your income is under £255 a week.

For couples - both of whom are State Pension age - he explained that you'll likely be eligible if your combined income is less than £363 a week, but that you may also get it if the amount falls under £380 a week.

Mr Lewis added: "Don't stall, just call (or check online) to see if you're due it..." He further explained that people can check their eligibility on Gov.uk - or by calling 0800 99 1234, or 0808 100 6165 in Northern Ireland.

Beyond supplementing income, Pension Credit carries additional benefits.

Notably, Pension Credit entitles those aged 75 and over to receive a free TV Licence.

You could also be entitled to Housing Benefit if you rent your property, support for Mortgage Interest if you own your home, a Council Tax reduction, assistance with NHS dental treatment, eyewear and travel costs for hospital appointments, help with heating bills through the Warm Home Discount Scheme, and a discounted rate on Royal Mail's redirection service should you move.
