Best junior stocks and shares ISA platforms

Junior ISAs can be a great way to save and invest for your child’s future.

Parents, relatives and friends can contribute a total of £9,000 into the account each tax year, and any investment gains are tax-free.

Junior ISAs have grown in popularity since launching in 2011. Like adult ISAs, there are two types of Junior ISA: cash ISAs, and stocks and shares ISAs. Almost £5bn is held in junior stocks and shares ISAs, while just over £4bn is held in junior cash ISAs, according to HMRC.

However, cash junior ISAs are more popular, with 737,000 cash junior ISAs paid into during 2021-22, according to the latest figures. In contrast, only 475,000 stocks and shares junior ISAs had money paid into them.

Despite junior cash ISAs being a more popular choice among parents, a junior stocks and shares ISA is often a better choice, especially if the child is young.

This is because shares almost always beat cash over long time periods. You can open a Junior ISA for a baby, and the money can’t be withdrawn until the child turns 18 – giving you quite a long timeframe. So you should have time for your child’s savings to ride out any market downturns.

But, it can feel overwhelming trying to work out which junior stocks and shares ISA to open. There are lots of investment platforms to choose from, all with their own pros and cons. Some are particularly cheap, while others may offer better investment choice, or more sustainable or ethical funds. 

We round up the best junior stocks and shares platforms to help you choose a product that is easy to use and should build up a decent nest egg for your child to spend or save when they reach their 18th birthday.

Best Junior ISAs for low fees

As most investors know, the one thing you do have control over when it comes to investing is the amount you spend in fees. Future investment returns are anyone’s guess, but you can reduce the impact of fees eating into your returns by simply choosing a product with low charges.

The cheapest Junior ISA will depend on how you want to use it: how much money are you planning to pay in? Do you want to buy funds or shares, and how often do you want to trade them?

To give a flavour of how the costs stack up, we asked Justin Modray, founder of Candid Money and Compare Fund Platforms, to crunch the numbers for a £5,000 Junior ISA containing five funds. Here’s how the annual costs compare for six low-cost Junior ISAs (excluding fees for the underlying funds): 

Fidelity and Hargreaves Lansdown are the cheapest, with no annual platform fee (you will need to pay fees on the underlying investments, as you would with most providers). Watch out for fees if buying or selling investments over the phone or by post.

Hargreaves Lansdown previously charged an annual fee for its Junior ISA, but slashed it to zero in March 2023, in a bid to draw in younger investors.

Modray adds that AJ Bell has a competitive platform fee (0.25%), although the £1.50 fund dealing fee may deter more active investors.

According to Modray, the key for parents when choosing a Junior ISA platform is low platform charges along with decent investment choice. It’s also worth checking there are no fees to move the account elsewhere in future, for example Charles Stanley Direct charges £10 per investment to transfer the ISA “as is” (compared to liquidating the investments and transferring the ISA as cash). 

Award-winning Junior ISAs

While fees are important, you also need to be comfortable with other aspects, such as customer service, and ease of use for parents or friends and family who may not be expert investors.

Bear in mind that, while a parent or guardian must open the Junior ISA, anyone can pay money into it – just make sure you don’t breach the £9,000 annual allowance.

We looked at Boring Money’s Junior ISA Best Buys, which highlight the best stocks and shares Junior ISAs for non-expert people saving for kids. There are nine winners for 2023: 

• AJ Bell
• Bestinvest
• Fidelity
• Hargreaves Lansdown
• Interactive Investor
• Moneyfarm
• Nutmeg
• Vanguard
• Wealthify

Boring Money notes that Vanguard is low cost (a potential downside is it only offers funds, not shares), and that Interactive Investor is good value for large portfolios. 

Nutmeg and Moneyfarm were commended for being “really easy to use”, while with Wealthify you can invest with just £1.

Boring Money likes Hargreaves Lansdown’s excellent customer service, and the free financial coaching on offer from Bestinvest. AJ Bell and Fidelity were commended for their online investment content and research tools.

A few Junior ISA rules

If you’ve set up a Junior ISA and want to switch to a competitor – perhaps to reduce the fees, or get a better user experience or investment range – go for it!

Parents are allowed to move the Junior ISA to a different provider, just watch out for any exit fees (there could be a charge to transfer a stocks and shares account “in-specie”, in which case consider converting to cash first).

You can also move a child trust fund into a Junior ISA, which could significantly cut your fees and increase your investment choice, as CTFs are now considered old, legacy products.

As mentioned, the annual allowance is £9,000, and you can split this across a cash Junior ISA and stocks and shares Junior ISA. So, you could contribute £2,000 to a cash Junior ISA, while up to £7,000 is paid into a stocks and shares account.

Bear in mind that a child can only hold one cash Junior ISA and one stocks and shares Junior ISA.

The £9,000 limit is on top of the £20,000 allowance that adults have for their ISAs.

The cash inside the Junior ISA belongs to the child and cannot be withdrawn until they turn 18, although teenagers can take control of the account from age 16.
