A Junior SIPP (Self-Invested Personal Pension) is a long-term retirement account you can open for your child. While they won’t be able to access the money until later in life, starting early gives investments decades to grow, potentially turning small, regular contributions into a meaningful pension pot over time.

Junior SIPPs also benefit from government tax relief on contributions, which can boost the total amount invested each year. Because the money is locked away until adulthood, this type of account is best suited to families who want to focus specifically on long-term retirement planning rather than shorter-term goals.

Only a small number of U.K. providers offer Junior SIPPs. In this guide, I’ve compared the available options looking at costs, investment choice, and ease of use to help you decide whether a Junior SIPP fits your child’s long-term financial plan.

Review

Bestinvest is a very good broker that should appeal to a wide range of investors. Fees are competitive, particularly if you invest in funds or US shares, and the investment options are extensive. The Bestinvest platform is relatively easy to use and the offer of a free 45 minute session with a financial coach can be a useful starting point for newer investors. Bestinvest is also a great option for a Junior SIPP, as it is one of very few UK brokers offering children’s pensions and with a low entry point.

Pros

Low minimum investment for junior SIPP (junior pension).
Free to buy and sell US shares.
Pays interest of 4.4% on cash held in any account.

Cons

1. Hargreaves Lansdown - Best Junior SIPP

Company	Overall Rating	Minimum Deposit	SIPP	ISA	Investment Choices
Hargreaves Lansdown		£100	Yes	Yes

Hargreaves Lansdown is top pick for a Junior SIPP because it combines a trusted, large-scale platform with an excellent investing experience for families. It’s one of the few major U.K. providers that offers a Junior SIPP at all, and it backs that up with strong support, robust tools, and a large investment lineup.

Huge choice of investments, including ready-made options. Inside the Junior SIPP you can invest in thousands of funds, shares, and ETFs, with the option to use ready-made portfolios if you’d rather not build everything from scratch. For parents who want flexibility as their child’s pension grows over time, Hargreaves Lansdown gives you plenty of room to adjust strategy without needing to switch providers.

Clear fee structure with strong value for fund investors. Fees depend on what you hold: there’s a 0.45% annual service fee for funds, while shares and ETFs are capped at £200 per year. Fund trading is free, and share/ETF trading is discounted for Junior accounts at £5.95 per trade, which makes it more manageable for long-term contributions and occasional rebalancing.

Elizabeth's take:

"Hargreaves Lansdown offers one of the most complete Junior SIPP packages available. Fund trades are free, the investment range is extensive, and the ability to contribute from £25 a month makes it practical for long-term family planning."

Elizabeth Anderson
Lead Writer for the UK

Solid platform, education, and contribution flexibility. The website is packed with research, guides, and calculators, and the platform is straightforward to manage once your child’s account is up and running. You can contribute from £25 per month or £100 as a lump sum, with the flexibility to pause anytime, which is a practical setup for families investing steadily long term.

Hargreaves Lansdown mobile app investment discovery

The Hargreaves Lansdown mobile app is easy to use but not as extensive as other brokers such as IG, Trading 212, Saxo or IBKR.

2. Bestinvest - Flexible junior pensions

Company	Overall Rating	Minimum Deposit	SIPP	ISA	Investment Choices
Bestinvest		£50	Yes	Yes

Bestinvest offers a Junior SIPP with a low barrier to entry, making it accessible for families who want to start contributing smaller amounts. While there’s no formal minimum to open or transfer an account, the minimum transaction amount is £50. Contributions can be made by debit card, bank transfer, direct debit, or standing order, all managed online. Because of ID requirements, the account must be opened using an application form (either by post or electronically via DocuSign), rather than fully online. The ability to link multiple family accounts under one login can also make it easier to manage pensions for more than one child.

Clear fee structure with some ongoing charges. Bestinvest’s fees are competitive in some areas, particularly for funds and U.S. shares, which are free to trade (foreign exchange fees of 0.95% still apply). U.K. share and ETF trades cost £4.95 per deal. An annual service fee of 0.2% applies to ready-made portfolios and U.S. shares, and 0.4% applies to other investments. For example, a £1,000 Junior SIPP invested at 0.4% would incur £4 per year in service fees, plus any underlying fund charges. There is no minimum monthly service fee for Junior SIPPs.

Balanced investment choice and guidance. Investors can choose from a broad, though not market-leading, range of funds, shares, ETFs, and investment trusts. Bestinvest also offers 19 ready-made portfolios, with ongoing charges starting at 0.3% before platform fees. A notable feature is the free 45-minute coaching session with a qualified financial planner, which may help parents better understand long-term investing for children. More in-depth portfolio reviews are available for an additional fee.

Searching for investments on the Bestinvest web platform.

With Bestinvest’s online investment search function you can filter and compare funds, shares, and ETFs by criteria such as sector, performance, and charges.

Usability and educational support. The platform provides a clear portfolio overview, including performance figures and asset allocation charts. Fees are transparently displayed within the transaction area. While the mobile app is functional rather than advanced, it allows users to place trades and manage accounts. Bestinvest also stands out for its educational content, with detailed guides, webinars, and investment commentary designed to support both newer and more active investors.

3. Fidelity - Best for large investments

Company	Overall Rating	Minimum Deposit	SIPP	ISA	Investment Choices
Fidelity International		£1000 info	Yes	Yes

Fidelity’s Junior SIPP can be cost-effective, particularly if you plan to invest mainly in funds. There are no service fees on Junior accounts, which helps reduce ongoing platform costs compared to providers that charge a percentage fee. Funds are free to buy and sell, although you will still pay the underlying fund’s own ongoing charges. Share and ETF trades cost £7.50 online, or £1.50 if you invest monthly through a regular savings plan. This means the account tends to suit longer-term investors rather than those making frequent one-off trades.

Higher minimum contributions. One of the main drawbacks is the entry requirement. Fidelity requires a minimum lump sum of £1,000 (or £800 once tax relief is applied) for Junior SIPP contributions. Alternatively, you can set up regular investments from £25 per month. This higher starting amount may be a barrier for families who want to begin with smaller contributions, especially when other platforms allow lower minimum payments.

Wide investment choice. Fidelity offers a broad range of investments, including thousands of funds, shares, ETFs and investment trusts. Tools such as the ‘Select 50’ list and sustainable investment filters can help narrow down options. For those seeking more support, financial advice is available for larger portfolios, although this comes with separate fees. Overall, the range is well suited to traditional, long-term investors.

Selecting BP as a share to purchase on the Fidelity UK mobile app.

Fidelity U.K. mobile app trade ticket with BP selected as the share to purchase illustrates how you can buy individual U.K. and international shares alongside thousands of funds, ETFs, and investment trusts available on the platform.

Solid platform with strong education. The Junior SIPP can be opened online and funded by debit card or bank transfer, and linked to an existing Fidelity account for easier oversight. The website provides detailed research, guides, webinars and educational material. While the mobile app is functional and includes charting tools, it is less focused on investment discovery, so it works best if you already know what you want to invest in.

4. AJ Bell - Extensive fund range

Company	Overall Rating	Minimum Deposit	SIPP	ISA	Investment Choices
AJ Bell		£250	Yes	Yes

AJ Bell’s Junior SIPP has a 0.25% annual platform fee on funds, with share and ETF custody charges capped at £120 per year. This can work out slightly cheaper than some traditional rivals, particularly for larger portfolios. However, there is a £1.50 dealing fee for fund trades and £5 per trade for shares, ETFs, and investment trusts. These charges can add up if you’re investing small amounts or trading regularly.

Strong investment range and account flexibility. You can access a wide selection of shares, funds, ETFs, investment trusts, bonds, and gilts. The Junior SIPP can be linked to your own AJ Bell account, which makes oversight easier for families managing multiple investments. AJ Bell also offers ready-made funds for those who prefer a simpler approach.

Minimum contributions and usability. The minimum lump sum contribution for a Junior SIPP is £500, while regular investments can start from £25 per month. The website offers detailed research and educational materials, and the mobile app is straightforward for managing investments on the go.

FAQs

Is a Junior SIPP actually worth it?

I have a Junior SIPP for each of my two children. Money is paid in around four times a year, mostly by their grandparents. There isn’t a huge amount in them currently but we think it’s a great way to get them ahead on their pension.

Starting a pension for your child can take the pressure off them into adulthood while they have other costs and financial goals to navigate. An initial payment of £800 shortly after birth (£1,000 after tax relief) would be worth almost £2,500 at age 18 if it grew by 5% a year. Contributions of £42 a month (£50 with tax relief) would be worth £17,551 after 18 years on returns of 5% a year.

When saving for your child, it’s more common to consider a Junior ISA or your own savings account before thinking about a pension for your child. But the benefit of a Junior SIPP is that money saved into the account gets a 20% boost thanks to tax relief. It can grow tax-free until the money is withdrawn. When withdrawn, the first 25% is tax-free, after which only income tax may apply.

Find out what ISAs are by reading my complete guide to ISAs in the UK. Learn how to open a stocks and shares ISA or figure out the best provider for you when ready to open an account.

Like with an adult pension, money can’t be withdrawn from a Junior SIPP until the child is in their mid-to-late 50s. A Junior SIPP is therefore designed for retirement and can’t be used for a child’s education or as a house deposit.

What is the youngest age to apply for a SIPP?

You can open a Junior SIPP shortly after your child has been born. There is no minimum age to open a Junior SIPP.

However, the account has to be opened by a parent or guardian. The child must be under the age of 18 and the account held in the child’s name, but the account is still managed by the parent or guardian.

Once the child turns 18, they get control over the account and how the money is invested. Like with a standard SIPP, they can’t withdraw money from the account until they reach the minimum age of 55 (rising to 57 in 2028) so it is certainly a long-term savings account.

Do Junior SIPPs get tax relief?

Yes, contributions into a Junior SIPP benefit from tax relief and this is one of the main advantages of a Junior SIPP. When you pay money into the SIPP, 20% tax relief applies. For example, if you pay in £100, a total of £125 goes into the account. Contributions are usually paid net of tax. So if you pay in £100, the Junior SIPP provider will then reclaim the 20% tax relief (£25) from HMRC and this will be paid into your account once received from HMRC, which can take a few weeks.

What is the difference between a SIPP and a Junior SIPP?

A SIPP is for U.K. adults aged 18 plus, while a Junior SIPP is for those under the age of 18. You can pay much more into an adult SIPP while benefiting from tax relief – up to £60,000 a year, compared with up to £3,600 a year for a Junior SIPP.

If you'd like to find the best overall SIPP provider for an adult, check out my guide to the best SIPP providers in the UK. If you'd like to learn more about the nuts and bolts of SIPPs in general, visit my complete guide to SIPPs in the UK.

Can grandparents pay into a Junior SIPP?

Yes, grandparents can pay into a Junior SIPP. One option is to pay money to the child’s parent to pay into the account on your behalf. Alternatively, you can usually make a payment directly if you have the account details. Just be aware of the annual Junior SIPP contribution limits.

Note that anyone can pay into a Junior SIPP, you don’t have to be family. Friends, godparents, or anyone else who cares to can contribute.

How many Junior SIPPs can I have?

You can have multiple Junior SIPPs but there are only a few providers of Junior SIPPs in the UK so there isn’t a lot of choice. There also isn’t much benefit to opening multiple Junior SIPPs with different providers as they all offer similar investments.

If you are unhappy with your current Junior SIPP provider, you can transfer to a new one. Go to your new provider's website to start the transfer process by filling in an application form. The transfer process typically takes 2 to 4 weeks.

How much can I contribute to a Junior SIPP?

The amount you can pay into each Junior SIPP is £2,880 a year – which increases to £3,600 after 20% tax relief is applied. This works out to £240 a month if spread across a year.
