Tesco Clubcard customers could be owed hundreds of pounds in unused vouchers without actually realising it.

There is now an easy way for its 16 million customers to check lost points online, to save them losing out on a cheaper shop or handy vouchers.

Shoppers earn points by spending money in store, at petrol stations and through using the supermarket's financial services, like a credit or debit card.

Money Saving Expert users claim they have retrieved £33,502 in lost vouchers - worth up to £134,010 when converted into Clubcard Rewards vouchers.

When you've collected at least £150 points in three months you are sent your points as vouchers, but some people lose the vouchers or forget to spend them. Tesco will not remind you if you have any leftover which you don't use, as reported by Kent Live.

To claim back up to two years of unused vouchers, log in to the Tesco Clubcard website with your email address, password and Clubcard number.

You then need to check you are registered for an account - so you don't miss out on money off vouchers - and check for unspent vouchers.

You can do this by clicking 'vouchers' on the left-hand side and you should see a table listing the vouchers you still have left to spend.

Either use the vouchers instantly using the listed code or print them off to use in store.

The supermarket giant caused outrage last month after announcing customers will no longer be able to quadruple their points when they swap them for vouchers at participating retailers, such as Pizza Express and Legoland.

Vouchers are now capped at three times the value of the points.

Tesco also announced it will remove a number of household brands from its shelves in a bid to rival its cheaper competitors.
