Best for People under 40 years old

Holly's ISA picks

21 Feb, 2025

By Holly Mackay, Founder & CEO

People under 40 who are starting out will typically not be super experienced in the world of investing, might feel a mild sense of alarm and probably be wondering, “do I have enough money to get involved in this world?”. Do not panic. You are in the right place. If you have at least £1 to invest, have a computer or a phone and 15 minutes spare, we can help.

As a general note, if you have expensive credit card debt or if you don’t have about 3 months’ salary built up in an easy access cash account as an emergency fund, it's worth taking the time to address these first before you dip your toes into the stock market.

Top ISA providers for those Under 40

Boring Money research shows that If we look at every investor under 40, the most commonly held sum of money in an ISA is £3,000.[1] If we look at the whole market, and think about who has reasonable fees and charges for this sum, and think about who offers the features and functionality you might like, then we identify:

Bestinvest

They have investment coaches you can speak to on the phone, so it’s a good option if you want to pick and choose but get a helping human hand along the way.

Who is HSBC good for?

It’s a good choice for less confident investors who are looking for the security of a big brand bank, and some handholding along the way. This service is a decent start.

Who is NatWest Invest good for?

NatWest Invest is good for people who already bank with NatWest (you have to be an existing customer to open an account). It’s also suited to beginner investors who would like a little bit of advice, people who don’t want too much choice, or those who are worried about hefty fees.

If we cut the Boring Money data differently we also see that that the average (versus the most common) amount held by investors under 40 is £26,000.[2] This higher number is heavily influenced by individuals who sit in the upper savings band as a result of inheriting money, receiving a big bonus or simply having saved more, if this sounds more like you then you might also like to consider:

AJ Bell Dodl

From AJ Bell, an app which offers some choice of funds and shares without going too far and overwhelming.

Who is AJ Bell Dodl good for?

AJ Bell Dodl is a good choice for beginners with smaller amounts to invest who want a good app, low charges, and not too much choice so there’s less chance of getting overwhelmed.

Who is Moneyfarm good for?

Moneyfarm is a good option for those who want some help with investing and who value the combo of a good digital customer experience with the ability to talk to real human beings on the phone. It’s also a decent fit for those who want some choice whilst still outsourcing most of the decisions to the experts.

Who is Vanguard good for?

Vanguard is a comforting, giant brand generally held in high regard. It’s low-cost with a platform charge of just 0.15% and has a suite of industry-respected ready-made options for beginners – the famed LifeStrategy range. However, it does have its flaws; Vanguard is a closed platform, meaning you can only use it to buy Vanguard’s own funds, so there’s limited choice.
