I only trust Premium Bonds and have put most of our meagre savings into them. www.thisismoney.co.uk/money/saving/article-10863341/Should-throw-savings-NS-Premium-Bonds.html “National Savings & Investments is finally increasing the number of Premium Bond prizes it pays out every month, boosting its 21million savers' chances of winning.”
"From next month (June 2022),NS&I will pay out an additional 1.4million prizes, cutting the monthly odds against winning for every £1 in Premium Bonds from 34,500 to one to 24,500 to one."
