Yes, it is possible to purchase a UK Lotto ticket on behalf of someone else. It is actually quite simple to do, and all you need to do is provide the other person’s name and address. Additionally, you may be asked to provide proof of identification for the other person such as their passport or driver’s license. After that, you can go ahead and purchase the ticket for them and make sure to keep the ticket in a safe place until the draw is made. Good luck!
