If you were born between 1 September 2002 and 2 January 2011, you almost certainly have a Child Trust Fund (CTF). These accounts are now maturing as the first generation turns 18 — and there is an estimated £2 billion sitting in accounts that have not been claimed.

How Much Could Be in Your CTF?

ScenarioEstimated value at 18
Government contributions only (£500 total) — cash CTF~£600–£700
Government contributions only — stocks and shares CTF~£800–£1,500+
Parents added £50/month for 18 years~£12,000–£15,000+
Maximum contributions each yearPotentially £50,000+
Average CTF value~£2,000–£2,500

The actual amount depends on which type of CTF you have (cash or stocks and shares) and how investments have performed.

How to Find Your CTF

Step by Step

StepAction
1Go to gov.uk/child-trust-funds/find-a-child-trust-fund
2Sign in with your Government Gateway account (create one if needed)
3HMRC will tell you the provider holding your CTF
4Contact the provider directly to access or manage your account

Other Ways to Find It

MethodDetail
Ask your parentsThey may have the original paperwork or annual statements
Check old paperworkLook for letters from HMRC or a CTF provider
Contact common providersOne Family, The Share Centre, Foresters Financial, NS&I — some of the largest
HMRC helpline0300 200 3300

Important: Many CTFs were set up automatically by HMRC when parents did not choose a provider. These “Revenue-allocated” accounts were placed with providers chosen by HMRC and parents may never have received the details.

What to Do When You Turn 18

Your Options

OptionProsCons
Transfer to an adult ISAKeeps tax-free status, money stays invested, uses none of your annual ISA allowanceYou don’t get the cash immediately
Transfer to a Lifetime ISATax-free growth PLUS 25% government bonus towards first home or retirementMoney locked in until age 60 (unless buying first home), penalty for early withdrawal
Withdraw the cashFull access to spend as you wishLoses tax-free status permanently — any future savings will be taxable
Leave it in the CTFNo action neededCTF products often have higher fees and fewer options than ISAs

Best Option for Most People: Transfer to an ISA

Transferring your CTF into an ISA keeps the money tax-free and does not count against your annual £20,000 ISA allowance. This is a direct transfer — the money moves from one tax-free wrapper to another.

ISA typeBest for
Cash ISAIf you need the money within 1–3 years (e.g. emergency fund, car)
Stocks and Shares ISAIf you can leave it invested for 5+ years (best for long-term growth)
Lifetime ISAIf you’re saving for a first home or retirement (get 25% government bonus up to £1,000/year)

How to Transfer CTF to an ISA

StepAction
1Choose which ISA you want to transfer to
2Open the ISA with your chosen provider (many accept transfers from CTFs)
3Ask the new ISA provider to initiate a transfer — do not withdraw and re-deposit
4The transfer usually takes 2–4 weeks
5No annual allowance is used

Do not withdraw and re-deposit. If you take the cash out and then put it into an ISA, it counts against your annual £20,000 ISA allowance. A direct transfer avoids this.

Common Questions

QuestionAnswer
Can my parents take the money?No — only the named account holder (you) can access it from age 18
Do I pay tax on CTF money?No — growth in a CTF is tax-free. However, if you withdraw and put it in a normal savings account, future interest may be taxable
What if I can’t find which provider has my CTF?Use the HMRC tool at gov.uk or call 0300 200 3300
Can I transfer part of the CTF to an ISA?Yes — you can do a full or partial transfer
Is there a deadline to claim?No — the money is yours indefinitely. But the sooner you move it to a competitive ISA, the better
What about Junior ISAs?If your CTF was transferred to a Junior ISA, the same rules apply at 18
