I do hold premium bonds. I'd absolutely tell my husband, we have complete transparency about our finances. Depends on the win, any big ones I'd treat my family, including my step-daughter, a great sister to my boys and a good friend to me, in ways I'd feel would benefit them. I'd hold back some for grandchildren to use wisely, not to squander. I wouldn't move house, I'm content where we are, maybe spend small amountS generally upgrading. I'd returf the lawn for instance, it looks sad at the moment and there was room from improvement before the drought. Having just come back from a swish hotel in Devon, more of that! I'd probably get myself a new car, o/h has just bought a new one for himself a couple of months ago, but I don't go far in mine these days. I'd give more to some charities I subscribe to.
