MoneyExpert.com’s research has showed that at the end of last year the worst paying child trust fund (CTF) was only 1.75% below the best buy. However the website’s latest figures showed that the gap has increased to some 2.75%.

According to MoneyExpert.com, a family that invests the maximum GBP1,200 in the first year only would lose out to the tune of around GBP1,780 over 18 years if they took the worst deal compared with the best.

Sean Gardner, CEO of MoneyExpert.com, said: The gap between the best and worst CTFs is too large to ignore. Many parents are planning to build up a healthy savings pot for their children and CTFs are a great way to do that.
