We explain the essentials simply and calmly. Child Trust Funds were set up by the government in 2005 as long‑term, tax‑free savings accounts for youngsters. Many accounts sit with UK providers and can be traced free via GOV.UK.
We will tell you what a Child Trust Fund is in plain English, why HMRC plays a role, and what parents, guardians and registered contacts can realistically do at each stage.
Expect clear steps on finding a provider, updating details, managing contributions and planning for maturity at 18. We stress that tracing an account is free and you should be wary of firms asking for a fee.
Our aim is practical help. We cover common stumbling blocks like missing paperwork, old addresses and identity checks. Read on for calm, step‑by‑step guidance to protect family money and keep records compliant.

Understanding Child Trust Funds and who has one
We outline what these long‑term savings accounts are, the dates that matter and the simple purpose behind them.
What it is and why it was set up
A Child Trust Fund (CTF) is a long‑term savings or investment account set up for a youngster to give them a financial head start at 18. The government opened accounts — and made initial contributions of at least £250 (or £500 for lower‑income families) — for every eligible child.
The idea was to build a nest egg that grows tax‑free and is ready when the young person becomes an adult. It encouraged a savings culture from birth, giving every child a stake regardless of family background.
Who was eligible
If the birth date falls between 1 September 2002 and 2 January 2011 there is a good chance an account was opened. The child also needed to be living in the UK and eligible for Child Benefit. HMRC issued vouchers to families, and if no account was opened within a set period, HMRC opened a default account on the child’s behalf — which means many parents may not even realise an account exists.
Some accounts were transferred into Junior ISAs after the rules changed in 2015. If that happened, the original CTF may no longer appear under the same provider name, but the money should still be held somewhere.
Cash vs Stocks & Shares and what “tax‑free” means
Cash CTFs behave like a savings account — steady, low risk. The provider pays interest, and the rate may vary over time.
Stocks & Shares CTFs invest in markets. Think of cash as a steady walk and investing as cycling: faster over distance but with bumps along the way.
Any growth and income inside the account are exempt from UK income tax and capital gains tax under current rules. This means interest, dividends and gains all accumulate without any tax deduction while the money stays in the CTF wrapper. However, investments can fall as well as rise, and the value at maturity may be less than the total paid in — particularly over shorter periods or during market downturns.
| Type | Typical behaviour | Best for |
|---|---|---|
| Cash CTF | Low volatility, interest‑based growth | Shorter horizons or low risk preference |
| Stocks & Shares CTF | Higher potential growth, market risk | Five‑plus year goals and long‑term growth |
| Tax treatment | Income and gains exempt inside the wrapper | Applies to both types under current rules |
What you need before you start: key details and documents
Start with the facts: collecting the right names, dates and numbers makes tracing straightforward and avoids unnecessary back‑and‑forth with HMRC or the provider.
Information to gather for the child and the requester
Have the requester’s full name, current address and contact number ready. The requester is usually the parent or guardian with parental responsibility.
Also confirm the child’s full name (as it appears on official records), current address and date of birth.
We stress accuracy: one wrong date or misspelled name on the form can slow the search significantly.
National Insurance number vs Unique Reference Number
The child’s National Insurance number is the quickest identifier if known. Young people receive their NI number automatically just before their 16th birthday.
A Unique Reference Number (URN) — sometimes printed on original CTF correspondence — will also speed up a trace if the NI number is missing.
Either number reduces follow‑up checks and helps HMRC match the request to the correct account provider quickly.
What to do if you can’t find the National Insurance number
Check letters sent around the child’s 16th birthday, school records, payslips or P60s. If the young person has a passport or provisional driving licence, those can support identity verification.
If the NI number is not available, you can still apply — include as much accurate information as possible (full name, date of birth, all known addresses) and be ready to provide ID if the provider or HMRC asks for it.
“Take ten minutes now to confirm details — it saves weeks later.”

How to use the GOV.UK service for HMRC Child Trust Fund tracing
We walk you through the GOV.UK tracing service so you can find an account quickly and with confidence.
Creating or recovering a Government Gateway login
First, register for a Government Gateway account or recover your user ID and password if you have used it before.
Choose clear contact details and keep the recovery codes safe. If you need to create new credentials, follow the on‑screen identity verification checks and confirm your email address.
Completing the online form
The online form asks for the requester’s and the young person’s full name, current and previous addresses and date of birth.
Include the National Insurance number or Unique Reference Number if known. Answer questions about changes of surname or moves plainly and accurately to avoid delays in matching.
After you submit and the postal option
Expect a reply with provider details within about 15 working days. Provider details mean who holds the account and how to contact them to update your records and gain access.
If you prefer not to use the online route, you can post the same information to HMRC using the address given on the GOV.UK guidance page. Use consistent spellings and include all previous addresses to speed up the matching process.
- Avoid delays: double‑check spellings, add past addresses and don’t leave fields blank.
- Once you have provider details, contact the provider directly to update records and access the account.
Free alternatives to tracing and how to avoid paid “finder” services
Begin with household checks and charitable help — there are free ways to track down an old account before you need any other service.
Step one: ask a parent or guardian if they have letters, statements or provider names. Old paperwork often shows the provider and the account number. A quick conversation at home can save days of searching.
Share Foundation support
The Share Foundation helps young people — particularly those who have been in local authority care — to find and access their CTF accounts. They can guide looked‑after young people and their carers through the entire process.
What they may ask for: basic personal information, proof of identity and consent to act on the young person’s behalf. This helps them contact the provider and request records without any charge to you.
Why you should not pay to find an account
There is no need to pay a finder. The government route and charities offer free help, and the process is designed to be straightforward. Paid adverts often promise fast results but may ask for unnecessary personal data and charge fees for something you can do yourself at no cost.
“Always try family first, then official and charity routes before giving information to any paid service.”
- Ask a parent or guardian → use the GOV.UK trace service → contact the Share Foundation if needed → then contact the provider directly.
- Only share necessary details. Keep control of sensitive information at all times.
| Route | Cost | Best for |
|---|---|---|
| Ask parents / guardians | Free | Quickest if paperwork available |
| GOV.UK trace service | Free | Official provider identification |
| Share Foundation | Free | Looked‑after young people or support with forms |
| Paid finder services | Fee charged | Avoid — use only as last resort and verify credentials first |
After you find the provider: updating details and accessing the account
Once you know who holds the account, your next step is to speak with them to bring records up to date and get access.
Contacting the provider and correcting your address
We advise calling the provider using the telephone number found on their website or in their response letter. They will ask for basic information to confirm identity before making any changes.
Be ready to give the registered name, date of birth and any previous addresses if the account is old. That helps the provider match records and avoid repeated verification checks.
Providers will update contact details once identity is confirmed. Keep a note of the date you called, the adviser’s name and any reference number for your records.
Understanding portals and account numbers
Many providers offer an online portal. The login usually shows the current value, contribution history and statements, but it will not allow withdrawal before the child turns 18.
Look for a client account number on annual letters or statements. This reference number speeds up verification and avoids confusion with other identifiers.
- What HMRC gives you: the provider identity. HMRC does not manage the account day‑to‑day — that is the provider’s responsibility.
- Simple family record: keep a note of the provider name, account number, registered contact details and latest correspondence date.
- Expect small admin hurdles (old postcodes, mismatched names after marriage). Have ID and any statements ready to resolve these quickly.
“Contact the provider promptly and keep a simple record — it saves time later.”
Managing a Child Trust Fund as a parent, guardian or registered contact
A calm, routine approach is the best way to protect a youngster’s long‑term savings. We explain practical steps for the registered contact and what changes when the youngster turns 16 or 18.
Registered contact responsibilities and keeping records up to date
The registered contact is the adult with parental responsibility who manages the account while the child is under 18. This person has the authority to change providers, switch between cash and stocks & shares, and make contributions.
Keep addresses and contact details accurate with the provider at all times. Save letters and statements and note provider contact information — a simple folder (physical or digital) is enough.
Review the account type and risk level periodically. If the investment no longer suits your family’s aims or the child is approaching 18, consider switching to a lower‑risk option or a different provider.
Control at age 16 and what changes (and what doesn’t)
When the youngster turns 16 they may take over management of the account. They can become the registered contact, change providers and switch investment types. Parents cannot prevent this choice — it is the young person’s legal right.
However, taking management control does not mean they can access the money. Withdrawals still wait until the account matures at 18.
If the child can’t manage finances: Lasting Power of Attorney and Court of Protection
If the young person lacks the mental capacity to manage their own affairs once they reach 18, a Lasting Power of Attorney (LPA) — specifically a property and financial affairs LPA — can be set up in advance if they have capacity at the time of signing. If capacity is already lacking, an application to the Court of Protection for a deputyship order will be needed so that a deputy can manage the CTF funds on their behalf.
For official guidance on provider duties and legal processes see the government notes and our practical guide:
“An annual admin routine keeps the account ready for the day the child turns 18.”
We recommend a short yearly checklist: confirm addresses with the provider, read the latest statement, record the provider phone number and review whether any further contributions make sense.
Adding money to an existing CTF: rules, limits and gifting implications
Top‑ups are possible even though new CTFs can no longer be opened. We explain how to pay in and what the limits mean in practice.
How top-ups work
You can add money by Direct Debit, cheque, or by debit card over the phone. Providers differ, so check the provider’s exact process and accepted payment methods first.
Many accept lump sums from £10 by cheque and regular monthly amounts from £10 by Direct Debit. Multiple people can contribute — parents, grandparents, other family members and friends — and it all counts towards the same annual limit.
Subscription limit explained
The annual subscription limit is up to £9,000. This is measured from the youngster’s birthday to the day before their next birthday, not the tax year. It is the same limit that applies to Junior ISAs, and a child can only hold either a CTF or a Junior ISA — not both — in any given subscription year.
All contributions into the same account count towards this cap, regardless of who pays in.
Important gifting rule
Once you pay in, the money belongs to the child and cannot be withdrawn before age 18, except in very limited, exceptional cases (such as the child’s terminal illness or death) handled through official routes.
It is worth noting that contributions from parents and grandparents may also have implications for inheritance tax planning. Gifts into a CTF are treated as gifts to the child for IHT purposes. Small, regular contributions from surplus income could potentially qualify as normal expenditure out of income — an exemption from IHT — but this needs to be properly documented. For larger lump sums, the annual gift exemption of £3,000 per person may apply.
Only contribute money you truly mean to give away — it becomes the youngster’s property once paid in.
- Set a reminder around the birthday boundary to avoid exceeding the subscription limit.
- Keep a short log of who paid what and when, and confirm receipts with the provider.
- Decide whether cash savings (steady interest) or invested options (potential growth with market risk) suit your aims — particularly as the child approaches 18.
| Topic | Typical options | Practical note |
|---|---|---|
| Payment methods | Direct Debit, cheque, phone debit card | Check provider details for exact steps |
| Minimums | Regular from £10; lump sums from £10 | Providers may set their own minimum amounts |
| Subscription limit | Up to £9,000 per birthday year | All contributors share the same allowance |
| Ownership | Money becomes the youngster’s | No withdrawals before 18 except in rare authorised cases |
What happens when the Child Trust Fund matures at 18
At 18 the account becomes a Matured Child Trust Fund. The account does not disappear. Control simply moves fully to the young adult and they decide the next steps. No one else — not parents, not the provider — can direct what happens to the money.
Many providers write about 20 days before the 18th birthday with clear instructions. The letter usually explains three straightforward options: withdraw some or all of the money, keep it invested within the matured CTF (though some providers may move it to a cash account if no instructions are received), or transfer to an adult ISA to maintain the tax‑free wrapper.
Matured account choices and practical steps
To withdraw, the young adult normally needs a UK current or savings account in their own name. Providers will not pay into third‑party accounts or accounts held by parents.
Expect identity and anti‑money‑laundering checks. Providers may ask for posted copies of ID documents and proof of address, and this can delay release by a few weeks. Starting the process early — even before the 18th birthday — helps avoid unnecessary waiting.
Accepted ID and how to reduce delays
- Accepted examples: current signed passport, photocard driving licence, UK birth or adoption certificate, or official benefit/tax credit letters showing name and address.
- Update addresses with the provider before the 18th birthday. Gather ID well in advance. Keep dates and copies of all correspondence.
“Prepare documents early and check the provider’s list — it speeds access to the money.”
Conclusion
Start with one clear step: confirm eligibility dates and gather names, dates of birth and accepted ID before you trace an account.
Use the free GOV.UK tracing service and, if needed, the Share Foundation for support. Don’t pay a finder — official and charity routes cost nothing.
Remember: money in a Child Trust Fund is a genuine gift and is locked until age 18. At maturity the young person can withdraw, keep investing, or move the pot to an adult ISA — subject to identity checks and provider processes.
If the young person lacks capacity, seek legal advice early about a Lasting Power of Attorney or Court of Protection deputyship to ensure someone can manage the funds on their behalf.
Action checklist: check dates, collect ID, use the trace service, contact the provider and keep simple records. For more explanation see our guide on what is a childhood trust fund.
