Claiming from the National Lottery
If your prize is up to £75, you can claim it in cash from any National Lottery retailer. All you've got to do is give them your winning ticket to validate through their Lottery terminal. The terminal will then produce a validation slip which will show the value of your prize. Check this against the amount paid out and return it to the retailer.
At their discretion, all retailers can pay prizes up to £200 in cash. Some National Lottery retailers are authorised to pay prizes of up to £500. National Lottery Post Offices will pay out prizes of up to £10,000, though prizes over £500 will be paid by cheque.
Anything above £10,000 must be claimed in person from a National Lottery Regional Centre and will be paid by cheque (no cash is held on these premises).
If you match all six main numbers, or five plus the bonus number, please call The National Lottery Line immediately for assistance in claiming your prize. Ring 0845 9 100 000 (calls normally charged at local rate in the UK).
To claim any prize above £500, you will have to complete a Claim Form and give proof of your identity. If you are claiming a large prize, additional checks on your winning ticket may be conducted.
All National Lottery prizes must be claimed by 11.00pm, 180 days after the winning draw. You can also claim your winnings by post. Send your winning ticket and the completed Claim Form to this address: The National Lottery, Accounts Dept., P.O. Box 287, Watford WD1 8TT
