How old is the old dear now? For a friend.Just for your information. Talking to a bloke from Littlewoods who was about to present an old dear with a cheque for £1m, he said that they advise anyone under 40 winning a similar amount that it’s not enough to enable them to give up work. This was nearly 25 years ago!
As for living on £1m, it would depend.
You could make a reasonable income from it, no reason why you couldn't make about £20k a year from three quarters of that, after squaring yourself away with a nice house. Split that between you and a spouse and it would be tax free too, so equivalent to earning about 25k
