Detailed Provider Reviews
Hargreaves Lansdown JISA, A Popular Choice for Parents
Hargreaves Lansdown offers a wide selection of funds and excellent customer service. It’s especially suited for parents who want flexibility and the option for family and friends to contribute easily.
- Pros: No annual fees, wide fund selection, exceptional customer service.
- Cons: No cash JISA option.
- Ideal for: Cost-conscious parents.
Fidelity International JISA, No Service Fee and a Wide Fund Range
Fidelity charges no service fee at all on its Junior ISA, matching Hargreaves Lansdown as one of only two major platforms offering a genuinely free JISA. Combined with a broad range of funds and ETFs, it is a strong choice for parents who want cost and choice without a trade-off.
- Pros: No service fee, excellent fund and ETF choice.
- Cons: Dealing charges apply if you buy individual shares rather than funds, £1.50 per trade through a regular savings plan, or £7.50 for an ad hoc online trade.
- Ideal for: Parents investing mainly in funds who want a free account with broad choice.
Freetrade JISA, Free Access to the Widest Investment Range
Freetrade launched its Junior Stocks and Shares ISA in April 2026, and it is available on every plan including the free Basic tier, with no account fee and no commission on trades. Parents get access to over 8,000 UK and global investments, stocks, ETFs, funds, bonds, and UK Treasury Bills, which is a considerably wider range than the fund-only free options.
- Pros: No account fee, no trading fees, widest investment range among the free options, backed by IG Group.
- Cons: New to the JISA market as of 2026, so a shorter track record than established providers.
- Ideal for: Parents who want free investing without being restricted to a fund-only platform.
AJ Bell JISA
AJ Bell’s Junior ISA platform fee is capped at £2.50 a month, so £30 a year, regardless of how large the pot grows. Share dealing costs £5 per trade, but since May 2026 the regular monthly investing route most parents use, from £25 a month, has been fee-free. For a parent contributing monthly rather than trading ad hoc, this puts AJ Bell close to a flat £30 a year rather than the old 0.25% plus £1.50 combination.
- Pros: Capped fee structure, free regular investing, great for DIY investors.
- Cons: £5 per-trade fee applies outside the regular investing service, so ad hoc share purchases add up.
- Ideal for: Parents happy to set up a regular monthly contribution rather than trade ad hoc.
Vanguard JISA
- Pros: Lowest fees, simple investment choices.
- Cons: Limited to Vanguard fund options only
- Ideal for: Parents seeking simplicity.
Interactive Investor JISA
Interactive Investor moved to a Core, Plus, and Premium subscription structure in February 2026. Junior ISAs are only available on the Plus plan (£14.99 a month) or Premium, not the entry-level Core plan. The Plus plan covers unlimited free Junior ISAs for all your children plus fee-free accounts for up to five family members, which makes it more competitive for larger families than the headline monthly cost suggests.
- Pros: Family-linked accounts, zero trading fees, unlimited free Junior ISAs on the Plus plan.
- Cons: Requires the £14.99/month Plus plan at minimum, which is expensive for a single small Junior ISA on its own.
- Ideal for: Families with multiple children or existing Interactive Investor accounts, where the flat fee is shared across several JISAs.
Nutmeg JISA (now J.P. Morgan Personal Investing)
Nutmeg was acquired by J.P. Morgan and rebranded to J.P. Morgan Personal Investing. The fully-managed portfolios still form the core offering, and fees now range from 0.25% to 0.75% depending on the portfolio style and balance, with fixed-allocation portfolios and balances over £100,000 sitting at the lower end.
- Pros: Fully-managed portfolios, convenient, backed by J.P. Morgan.
- Cons: Higher management fees than DIY platforms, brand change may cause confusion for existing customers.
- Ideal for: Busy parents who want a hands-off managed portfolio.
Wealthify JISA
Wealthify’s flat 0.60% management fee is unchanged, but the minimum deposit to open a Junior ISA rose to £500 in February 2026, up from £1 previously.
- Pros: Ethical investing options, simple flat fee structure.
- Cons: Higher platform fees than DIY platforms, £500 minimum deposit is a real barrier for parents wanting to start small.
- Ideal for: Ethical investing beginners with a lump sum ready to invest.
Moneybox JISA
Moneybox charges a £1 monthly subscription fee on top of a 0.45% annual platform fee, plus underlying fund charges. This combined cost is higher than the flat £1/month the fee was previously presented as.
- Pros: User-friendly app, automated investing, low £1 minimum to start.
- Cons: £1/month subscription plus 0.45% platform fee adds up to a higher combined cost than many DIY platforms.
- Ideal for: Tech-savvy parents who value automation over the lowest possible fee.
