Our Expert Opinion on Cambridge Building Society 3 Year Fixed Rate Children's Bond

Jonny PeaseCo-Founder, DepositScout

This account suits parents or grandparents looking to lock away money for a child over three years, with a 4.15% rate that sits 1.05% above CPI inflation of 3.1% as of Aug 2026, so the money does grow in real terms. The minimum is £1,000 and the maximum £50,000, and interest can either compound within the bond or be paid out annually to a separate account. The main catch is that there is no access until maturity, so the money is fully locked away for three years. If you want something similar but slightly higher, Kent Reliance's Demelza Children's Savings Account pays 4.18%.
