| Under-18 Bank Accounts — Key Facts | |
|---|---|
| Age range | Current accounts: age 11-17; some savings accounts from birth |
| Parental consent | Required for under-16s on most accounts |
| No overdraft | Overdrafts not available on under-18 accounts by FCA design |
| Junior ISA allowance | £9,000/year tax-free (2026/27) |

A dedicated under-18 bank account teaches practical money skills — budgeting, saving, understanding statements — in a controlled environment. UK banks offer two main products: current accounts (for spending and receiving money) and savings accounts (for growing money). Some convert automatically to adult accounts at 18; others must be closed.

Junior ISA — Best Savings Vehicle for Under-18s
A Junior ISA lets you save up to £9,000 per tax year (2026/27) free of UK tax on interest and growth. Two types: Cash JISA (interest-paying savings) and Stocks and Shares JISA (invested for long-term growth). JISAs can only be opened by a parent or guardian. The child can manage it from age 16 and withdraw from age 18. Money is locked until age 18 except in cases of terminal illness. (Source: HMRC Junior ISA guidance)
| JISA type | Best for | Risk | Example providers |
|---|---|---|---|
| Cash JISA | Short-term (under 5 years to age 18) | No risk to capital | Coventry BS, Nationwide, Halifax |
| Stocks and Shares JISA | Long-term growth (10+ years) | Capital at risk; expected to outperform cash over 10+ years | Vanguard, Fidelity, Hargreaves Lansdown |
Child Trust Funds — Born Before 2011
Children born between 1 September 2002 and 2 January 2011 received a Child Trust Fund. These can be transferred to a JISA. Track an unknown CTF at gov.uk/child-trust-funds. Many CTFs invested in stocks have grown significantly over 15+ years.
Parental Controls and Safeguards
FCA rules prohibit overdrafts on under-18 accounts. Most banks also apply: spending limits; contactless limits; gambling site blocks; and parental transaction visibility. Digital-first accounts (Starling Kite, GoHenry) offer the most granular controls but charge a monthly fee or require an adult account with the same provider.
What Happens at 18
Most accounts convert automatically to adult accounts at 18. The account number and sort code are retained. At this point a credit file is created, overdraft facilities may be offered, and the account holder takes full legal responsibility. Parents lose visibility automatically. JISAs convert to adult ISAs — funds become accessible but retain their ISA tax wrapper.

Frequently Asked Questions
Can my child open a bank account without me?
Under-16s cannot open a bank account independently — parental or guardian consent is required. At 16-17 some banks (Monzo, Halifax) allow independent applications with identity verification.
Does my child pay tax on savings interest?
Children have the same Personal Allowance (£12,570) as adults — so interest is effectively tax-free up to that amount. However, if a parent gifts money that earns more than £100 interest per year, that income is treated as the parent's for tax purposes. This rule does not apply to gifts from grandparents or third parties.
