Best Investment Apps UK for Beginners: 5 Compared

Picking the best investment app UK beginners should actually open comes down to three things: how little you can start with, what it charges once your money is in there, and whether the app makes sense the first time you open it. Most of the well-known names now let you begin with a few pounds and hold everything inside a tax-free Stocks and Shares ISA, so the deciding factors are fees and how much hand-holding you want.

This guide compares five apps that suit people who are new to investing, with the current pricing and the catches that only show up once you start moving money around. None of the links here are affiliate links, and there are no prices for the investments themselves because those change daily.

What matters when you are starting out

A beginner does not need advanced charting or access to obscure markets. What actually moves the needle early on is low cost and low friction:

• Minimum to start. Some apps let you invest £1, others want £100 before you can open an account.
• Platform and dealing fees. A flat account fee or a percentage cut quietly eats into small pots more than most beginners expect.
• The ISA wrapper. A Stocks and Shares ISA shelters your gains and dividends from tax. You can pay in up to £20,000 across your ISAs in the 2025/26 tax year.
• FX fees. If you buy US shares, the app converts pounds to dollars and charges a percentage for it. On a small portfolio this is one of the biggest hidden costs.
• How guided it is. Ready-made portfolios suit people who do not want to pick anything. Do-it-yourself apps hand you the full menu.

Every app below is authorised by the Financial Conduct Authority, and your investments are protected by the FSCS up to £85,000 if the provider fails. That protection covers provider failure, not market losses: the value of investments still goes down as well as up.

Trading 212: the strongest all-rounder for beginners

Trading 212 is the app most beginners end up recommending to each other, and for good reason. You can start from £1, there is no platform fee and no dealing commission, and the Stocks and Shares ISA is free to hold. It pays interest on uninvested cash sitting in your ISA, currently 3.8% AER with no cap on the balance, which is unusually generous.

The FX fee is 0.15%, the lowest of any app here, so buying US shares costs far less than it does elsewhere. Its “Pies” feature lets you build a basket of shares or funds and drip-feed money into it automatically, which is a clean way to keep a beginner investing regularly without thinking about it.

The one thing to watch is that the sheer breadth of choice can overwhelm a complete novice. If you want structure rather than a blank canvas, one of the guided apps below may suit you better.

Freetrade: clean and simple, now with a free ISA

Freetrade built its name on a stripped-back, easy-to-read app, and since January 2026 its Basic plan includes a Stocks and Shares ISA and a SIPP at no monthly cost. That change, made after IG Group bought Freetrade in April 2025, put it back in contention for cost-conscious beginners.

The trade-off is in the details. The Basic plan charges a 0.99% FX fee on any non-GBP trade, which is steep if you buy US shares often, and it pays only 1% interest on up to £1,000 of uninvested cash. Freetrade sells paid tiers (Standard and Plus) that cut the FX fee and lift the cash rate, but for a beginner sticking to UK shares and funds, the free Basic plan is perfectly usable.

Freetrade’s strength is clarity. If Trading 212 feels busy, Freetrade’s calmer layout is easier to learn on.

InvestEngine: cheapest way to run an ETF portfolio

InvestEngine is a specialist. It only offers exchange-traded funds, so you cannot buy individual company shares, but for a beginner who wants a diversified, low-cost portfolio that is arguably a feature rather than a limitation. Its do-it-yourself ISA has no account fee, no dealing fee and no ISA charge.

You can pick your own ETFs or hand the job to a managed portfolio for a 0.25% annual fee. The catch is the entry point: you need £100 to open an account, and regular investing starts at £10 a week, so it is less suited to someone wanting to test the water with a single pound.

If you already know you want a simple index-fund portfolio rather than to pick stocks, InvestEngine is the cheapest sensible home for it.

Moneybox: the gentlest on-ramp for nervous beginners

Moneybox is built for people who find investing intimidating. Its signature feature rounds up your everyday card spending to the nearest pound and invests the difference, so you build a pot almost without noticing. It also offers a Stocks and Shares ISA, a Lifetime ISA and pensions, all inside one friendly app with a lot of built-in education.

The cost is the reason it sits lower on this list for value. Moneybox charges a £1 monthly subscription plus a 0.45% annual platform fee. On a small pot that £1 a month is a meaningful percentage, so Moneybox makes most sense once your balance grows past a few thousand pounds, or if the round-up habit is the only thing getting you to invest at all.

Nutmeg: fully managed, if you want it done for you

Nutmeg is not a stock-picking app at all. You answer a few questions about your goals and risk appetite, and it builds and manages a portfolio for you. That completely removes the “what do I buy?” problem that stops many beginners.

The convenience has a price: management fees start around 0.75% a year on its fixed-allocation portfolios and rise for its fully managed range, on top of the underlying fund costs. That is far more than running your own ETF portfolio on InvestEngine. Nutmeg suits someone who values a genuinely hands-off experience and is happy to pay for it. If you would rather learn to invest yourself, one of the do-it-yourself apps above will cost you much less over time.

Which app should a beginner pick?

• Best all-rounder: Trading 212, for zero fees, a £1 start and the lowest FX charge.
• Simplest interface: Freetrade, now that its Basic ISA is free.
• Cheapest ETF portfolio: InvestEngine, if you are happy with funds over shares and can start with £100.
• Best for building the habit: Moneybox, for round-ups and education, once your pot is growing.
• Fully hands-off: Nutmeg, if you want a managed portfolio and will pay for the convenience.

Whichever you choose, the winning move as a beginner is boringly consistent: pick a low-cost app, use the ISA wrapper, invest a set amount every month, and leave it alone.

Frequently asked questions

What is the best investment app for beginners in the UK? For most beginners Trading 212 is the strongest choice, because you can start from £1, there are no platform or dealing fees, the Stocks and Shares ISA is free, and it charges the lowest currency-conversion fee of the popular apps. Freetrade is a close second if you prefer a simpler interface.

How much money do I need to start investing with an app? Some apps let you begin with as little as £1, including Trading 212 and Freetrade. Others set a higher bar: InvestEngine needs £100 to open an account. You do not need a lump sum to start; investing a small amount every month is a sound way to begin.

Are investment apps safe in the UK? Yes, provided the app is authorised by the Financial Conduct Authority. Your money is then covered by the FSCS up to £85,000 if the provider fails. That protection does not cover investment losses, because the value of investments can fall as well as rise.

Should a beginner use a Stocks and Shares ISA? For most people, yes. A Stocks and Shares ISA shelters your investment gains and dividends from tax, and you can pay in up to £20,000 in the 2025/26 tax year. Nearly every app on this list offers one at no extra cost.

Which app has the lowest fees for beginners? Trading 212 and InvestEngine both charge no platform or dealing fees on do-it-yourself investing. Trading 212 also has the lowest FX fee at 0.15%, making it cheaper for buying US shares. Managed apps such as Moneybox and Nutmeg charge more because they do more of the work for you.
