That assumes you only buy a house even then £300k wouldn’t get you much if you live in London for example. No cars, no holidays, no helping friends and family, all to live on £30k a year. Can see why some might want to top that up at least for a while.Some right f***ing whoppers on here mind saying they would still have to work and could only retire on that if they were getting on. If a 25 year old won that amount they could buy a house for 300k and still have 30k a year to live off till retirement and that's before interest.
