Best Investment Apps UK (2026): ISA,Low-Fee & Beginner Options
Investment apps have made investing in the UK far more accessible than it used to be. You no longer need a stockbroker, large lump sums, or complicated platforms — most people can start investing from their phone with as little as £1.
But “easy” doesn’t mean “risk-free”. Fees matter. Behaviour matters. And choosing the wrong app can quietly cost you thousands over time.
This guide focuses on the best UK investment apps for long-term investing, especially through a Stocks & Shares ISA. If you’re looking to build wealth steadily — not gamble on trades — this is the angle that actually makes sense.
I’ve used most of these apps myself over the years, and what matters far more than features is whether you actually stick with them.
Quick picks: best investment apps in the UK
If you just want the short answer, these are the apps that cover most people:
Best low-fee Stocks & Shares ISA: Trading 212
Best for ETF investing (cheapest long term): InvestEngine
Best for beginners investing small amounts: Moneybox
Best for hands-off managed investing: Wealthify
Best for DIY share picking (simple): Freetrade
Best for larger portfolios (flat fee): interactive investor
I’ll explain who each one is actually for below.
App | Best for | ISA available | Typical fees | Good choice if you… | Avoid if you… |
|---|---|---|---|---|---|
Low-fee DIY investing | Yes | No platform or dealing fees (FX on non-GBP assets) | want cheap, simple long-term investing | want managed portfolios | |
ETF investing | Yes | No platform fees (DIY); ETF fund fees apply | are happy investing only in ETFs | want individual shares | |
Beginners | Yes | £1/month + % fund fees | want to invest small amounts easily | want the cheapest option | |
Hands-off investing | Yes | Management + fund fees | want to invest and leave it alone | want the cheapest option | |
DIY share picking | Yes | ISA subscription + FX fees | want a simple DIY app | invest very small amounts | |
Large portfolios | Yes | Flat monthly fee + dealing | have £20k+ invested | are just starting out |
Capital at risk. Investments can go down as well as up.
How to choose the right investment app
Before picking an app, make two decisions. This matters more than the app itself.
ISA or GIA?
If you’re investing long term, a Stocks & Shares ISA should usually come first. Gains and dividends are tax-free, and you can invest up to £20,000 per tax year.
A GIA (General Investment Account) does the same job, but profits may be taxed. For most people, it only makes sense once ISA allowances are used.
If you’re unsure, I’ve broken this down properly in my Stocks & Shares ISA guide (internal link).
DIY or managed?
DIY apps work well if you buy diversified funds or ETFs and leave them alone.
Managed apps work well if you know you’ll tinker, panic, or lose interest.
I’ve tried both approaches over the years. The biggest risk usually isn’t the market — it’s checking your app too often.

If someone asked me today which investment app I’d suggest for low-cost, long-term investing in the UK, Trading 212 would be one of the easiest answers.
I’ve used it on and off over the years. It’s simple, genuinely low-cost, and doesn’t overwhelm you with tools you don’t need. You can invest in shares and ETFs, use a proper Stocks & Shares ISA, and leave your investments alone without constant prompts to trade.
For most people, that’s exactly what you want.
If you want a cheap, no-nonsense way to invest regularly and build wealth over time, Trading 212 is hard to beat.
Trading 212
Why Trading212 works
✅ No platform or dealing fees
✅ Stocks & Shares ISA available
✅ Fractional shares make monthly investing easy
✅ Clean, easy-to-use app
Where it falls short
❌ FX fees apply on non-UK investments
❌ Limited research tools
❌ Not suited to hands-off managed investing
⭐ ⭐ ⭐ ⭐ ⭐ 4.5/5
Best for: ETF investing at the lowest cost
Capital at risk
InvestEngine is one of the few apps where the fees really are as low as they look — as long as you’re happy sticking to ETFs.
There are no platform fees for DIY investors, ISAs and SIPPs are available, and the app keeps things refreshingly straightforward. ETFs are already diversified, which makes this a sensible option for long-term investing without overthinking.
If you want cheap, diversified investing without fuss, InvestEngine makes a lot of sense.
InvestEngine
Why InvestEngine works
✅ No platform fees for DIY investors
✅ ISA and SIPP available
✅ Wide range of low-cost ETFs
✅ Simple, uncluttered app
Where it falls short
❌ ETFs only — no individual shares
❌ Less flexibility for stock pickers
⭐ ⭐ ⭐ ⭐ ☆ 4.4/5
Best for: beginners investing small amounts
Capital at risk
Moneybox is designed for people who want investing to happen quietly in the background.
I’ve always seen it as a good first step into investing — especially if you’re starting with small monthly amounts. Round-ups, simple portfolios, and low minimums make it easy to build the habit without stressing over decisions.
It’s not the cheapest long term, but ease of use counts for a lot.
If you’re new to investing and want something you’ll actually use, Moneybox is a solid starting point.
Moneybox
Why Moneybox works
✅ Invest from as little as £1
✅ Stocks & Shares ISA, LISA and pension options
✅ Round-ups make investing automatic
✅ Very beginner-friendly app
Where it falls short
❌ Ongoing fees aren’t the lowest
❌ Limited choice for DIY investors
⭐ ⭐ ⭐ ⭐ ☆ 4.3/5
Best for: hands-off managed investing
Capital at risk
Wealthify is for people who don’t want to choose funds, rebalance portfolios, or check markets every five minutes.
You answer a few questions, pick a risk level, and everything is managed for you. It’s deliberately boring — which is usually exactly what long-term investing needs.
If you know you’ll overthink or panic-sell, Wealthify can actually save you from yourself.
Wealthify
Why Wealthify works
✅ Fully managed portfolios
✅ Stocks & Shares ISA available
✅ Clear risk levels
✅ No temptation to tinker
Where it falls short
❌ Higher fees than DIY platforms
❌ No control over individual investments
⭐ ⭐ ⭐ ⭐ ☆ 4.2/5
Best for: simple DIY share investing
Capital at risk
Freetrade sits somewhere between Trading 212 and traditional investment platforms.
The app is clean, easy to navigate, and lets you invest in shares and ETFs without a steep learning curve. There is a monthly fee for the ISA, which makes it less appealing for very small balances, but it’s still a decent DIY option.
If you want DIY investing without complexity and don’t mind a small subscription, Freetrade does the job.
Freetrade
Why Freetrade works
✅ Simple, easy-to-use app
✅ Stocks & Shares ISA available
✅ Good range of shares and ETFs
Where it falls short
❌ Monthly ISA fee
❌ FX fees apply
❌ Not the cheapest for small investors
⭐ ⭐ ⭐ ⭐ ☆ 4.3/5
Best for: larger portfolios using flat fees
Capital at risk
interactive investor is built for people with more money invested.
Instead of percentage-based fees, you pay a flat monthly fee — which can work out cheaper once your portfolio grows. You get access to ISAs, SIPPs, funds, shares, and solid research tools, but it’s overkill if you’re just starting out.
If you’ve built up a decent pot and want to keep fees predictable, this is one of the better options.
interactive Investor
Why interactive investor works
✅ Flat monthly fees suit larger portfolios
✅ Huge range of investments
✅ Strong research and tools
✅ ISA and SIPP available
Where it falls short
❌ Poor value for small balances
❌ Less beginner-friendly
Apps worth a brief mention (but not core picks)
Some apps don’t quite fit the main list but are still useful in specific cases:
• Plum and Chip – better viewed as saving apps with investing features
• AJ Bell Dodl – simple app backed by a major UK provider
• eToro – social trading and copy-trading; high temptation to overtrade
Are investment apps safe in the UK?
Most mainstream investment apps used in the UK are FCA-authorised. That doesn’t protect you from market losses — it just means the platform must follow UK rules.
FSCS protection applies only if a provider fails — it does not protect against losses from investing.
Final verdict: which investment app should you choose?
If you want one sensible default answer:
Trading 212 or InvestEngine, used through a Stocks & Shares ISA, investing monthly, and leaving it alone.
If you know you’ll fiddle or panic:
Moneybox or Wealthify will probably serve you better — even with slightly higher fees.
The best investment app isn’t the cleverest one. It’s the one you’ll still be using in 10 years.
FAQs: investment apps in the UK
What is the best investment app in the UK for beginners?
For most beginners, Moneybox is one of the easiest places to start. You can invest small amounts, use a Stocks & Shares ISA, and rely on simple portfolios without needing to pick individual investments.
If you’re comfortable choosing funds or ETFs yourself and want lower fees, Trading 212 is another strong option.
What is the best Stocks & Shares ISA investment app?
If low fees are your priority, Trading 212 and InvestEngine are two of the cheapest ISA options in the UK.\
For a more hands-off approach, managed platforms like Wealthify can make sense, even though fees are higher.
Can I start investing with £1 using an app?
Yes. Several UK investment apps let you start with as little as £1, including Moneybox. This makes them popular for beginners who want to invest monthly without committing large sums upfront.
Just be aware that flat monthly fees can make very small balances poor value over time.
Are investment apps safe in the UK?
Most well-known UK investment apps are authorised and regulated by the Financial Conduct Authority (FCA). This means they must follow UK rules, but it does not protect you from market losses.
FSCS protection for investments only applies in limited provider-failure scenarios — it won’t protect you if your investments fall in value.
Is it better to use a DIY or managed investment app?
DIY apps are usually cheaper and work well if you’re happy buying diversified funds or ETFs and leaving them alone.
Managed apps cost more but can be a better choice if you know you’ll tinker, panic, or stop investing when markets fall.
For many people, behaviour matters more than fees.
