What is the best savings account for a child UK?

Junior ISAs offer tax-free growth up to £9,000/year — often best for long-term saving. For accessible savings, children's easy access accounts teach money management. Premium Bonds are safe from NS&I but returns vary. Consider combination based on goals.

What's the difference between a Junior ISA and children's account?

Junior ISA: tax-free, locked until 18, higher contribution limit. Children's account: taxable (above £100/year from parents), accessible, teaches banking. Junior ISA for long-term growth, children's account for accessible savings and learning.

Can grandparents open savings for grandchildren?

Grandparents can contribute to existing Junior ISAs (parent must open). They can open Premium Bonds in child's name. Children's bank accounts usually need parent to open first. No £100 tax rule applies to grandparent gifts.

Should I choose Junior ISA or Premium Bonds for my child?

JISA for guaranteed tax-free growth (cash or stocks & shares). Premium Bonds for safe, prize-based returns (no guaranteed return but no losses). JISAs typically better for growth, Premium Bonds if you value safety and prize excitement.
