Make use of your own ISA allowance to invest for your grandchildren's future.
Keep in mind stock market investments can go down as well as up and you could get back less than you've invested. Tax treatment depends on individual circumstances and tax rules could change in the future.
New research from Scottish Friendly in conjunction with the Centre for Economics and Business Research, reveals that savers have received £75 billion in interest since ISAs were first introduced in 1999. However, these same savers could have achieved £202 billion in interest in returns if they had instead opted to invest in the stock market - £127 billion more.
