What is the first thing you would buy with a life-changing sum of cash? That is often where our minds wander when we're buying our lucky dips or inputting our family's birthday for the lotto draw. But what would you think if you found you out you were sat on a fortune - without even realising it? Well, for some people in the UK, that is the reality. The National Lottery publishes an online list of tickets which have not been claimed, or validated and paid - and there are currently five £1 million winning tickets. For some of the winning tickets, the deadline to claim is quickly approaching, with two tickets having deadlines in March. And if you need some spending inspiration, you can watch the video at the top of this page to see how a couple from Lancashire - who earlier this year landed a £61 million jackpot - plan to use their winnings. Here we’ve outlined how long lottery winners have to claim, how to claim winnings and the full location and number details of the unclaimed tickets. Winning lottery ticket holders have 180 days (approximately six months) from the draw date to claim the prize. If a valid claim is not received within this timeframe, the money and any interest earned on it will go to National Lottery Projects across the UK. Prize winnings of £500 and under can be claimed in store from a National Lottery retailer. Prizes over £500 and up to and including £50,000 can be claimed online. For prizes over £50,000, and monthly prize winnings (Set For Life), winning ticket holders should call the National Lottery on 0333 234 50 50 to confirm and arrange the winning claim. If a ticket has been damaged or destroyed, you still may be able to make a valid claim. An appeal should be filed within 30 days of the draw date. Details on the information you would need to provide can be found on the National Lottery website. £10,000 every month for one year - Doncaster This Set For Life ticket was bought in Doncaster.
