INVESTING FOR ROOKIES
Episode 8 of 12 • Building wealth one Monday at a time
What Actually Matters
The platform you invest through will be the home for potentially decades of your financial life. Picking the wrong one does not just cost you in fees, it can limit what you can buy, slow down your progress, and create headaches when you eventually want to move. Getting this decision right from the start is worth a proper look.
Welcome back to Investing for Rookies. We have now covered what investing is, when to start, how to evaluate assets, how exchanges work, and more. The natural next question is: where do you actually open an account and start? This week we are walking through everything worth considering when choosing an investment platform, with real examples and current figures so you can make an informed comparison rather than just going with whoever ran the most adverts.
Start Here: Regulation and Protection
Before fees, investment options, or app design, the very first thing to confirm about any platform is whether it is properly regulated and your money is protected if something goes wrong. This is non-negotiable, and every other consideration on this list comes after it.
In the UK, investment platforms should be authorised and regulated by the Financial Conduct Authority (FCA). You can verify any platform's status in seconds by searching its name on the FCA Register at register.fca.org.uk. Alongside FCA authorisation, look for coverage by the Financial Services Compensation Scheme (FSCS), which protects eligible client assets up to £85,000 per person per firm in the event of a platform failure.
It is also worth understanding what FSCS protection actually covers. It does not protect you against the value of your investments falling, that is just market risk, which is always yours to carry. What it does protect against is the platform itself failing as a business and being unable to return your assets. Your shares are also typically held in a segregated account, meaning they sit separately from the platform's own finances and cannot be claimed by creditors if the company goes under.
Understanding the Fee Structure
Fees on investment platforms are rarely presented as a single clear number. They come in several distinct layers, and the total cost of using a platform only becomes clear when you add all of them up for your specific situation. Here are the main ones to look for.
Account or Platform Fee
This is what you pay simply for holding your investments on the platform. It comes in two forms: a percentage of your total portfolio value charged annually, or a flat monthly or annual fee. Neither is automatically better. The right answer depends entirely on how large your portfolio is.
Percentage-based fees are cheaper when your portfolio is small, because the charge scales down with the balance. But as your portfolio grows, that percentage becomes a very large absolute number. A 0.35% annual charge on a £10,000 portfolio costs £35. On a £200,000 portfolio, it costs £700. Flat-fee platforms, by contrast, cost the same regardless of what your portfolio is worth, which makes them significantly more efficient for larger balances.
Trading or Dealing Fees
Some platforms charge a fee each time you buy or sell an asset. This can range from nothing at all to several pounds per transaction. For someone making a single large purchase and holding long-term, dealing fees matter very little. For someone investing smaller amounts regularly, even a modest fee per trade can eat significantly into returns.
Hargreaves Lansdown charges £6.95 per online share or ETF trade as of March 2026, reduced to £3.95 for frequent traders. Trading 212 and Freetrade both offer commission-free trading. For a beginner investing £100 a month, paying £6.95 every time to buy means starting each month already 6.95% down on that contribution, which is a significant drag before the market has even moved.
Foreign Exchange Fees
This is the fee most beginners completely overlook until they see it on their statement for the first time. When you buy an asset priced in a different currency from your account, the platform converts the currency on your behalf and takes a percentage for doing so. Buying a US-listed ETF from a GBP account, for instance, triggers a currency conversion from pounds to dollars.
Freetrade charges 0.99% FX fee on non-GBP trades on its Basic plan, dropping to 0.39% on the Plus plan. Trading 212 charges 0.15%. Hargreaves Lansdown charges 1% on the first £5,000 per transaction. If you are regularly buying US-listed ETFs with a UK account, this fee compounds meaningfully over time and should absolutely factor into your choice of platform.
Administrative Fees
A small number of platforms also charge for things like withdrawing cash, transferring your portfolio to another provider, or leaving your account inactive for an extended period. These fees are less common among modern platforms but worth scanning for in the terms and conditions before you commit. A platform transfer fee, in particular, can become a meaningful barrier to switching providers later if you decide to move.
Investment Universe: What Can You Actually Buy?
A platform with zero fees is not useful to you if it does not offer the investments you want. Before signing up, confirm that the platform gives you access to the specific stocks, ETFs, or funds you are interested in holding.
The range varies considerably. Hargreaves Lansdown offers the broadest selection of any major UK platform, including thousands of funds, shares across dozens of markets, ETFs, investment trusts, and bonds. Trading 212 and Freetrade offer a solid range of global stocks and ETFs, more than enough for most beginners building a simple diversified portfolio, but without the depth of fund or bond access that HL provides.
Two specific features worth checking:
Fractional shares: Some individual stocks carry a very high price per single share. At the time of writing, a single share of companies like Amazon or Berkshire Hathaway costs hundreds of pounds each. Platforms that support fractional investing let you buy a slice of a share for as little as £1, which dramatically lowers the barrier to entry and makes it easier to diversify without needing large lump sums. Trading 212 supports fractional shares with a minimum investment of £1. Freetrade does too. Hargreaves Lansdown does not currently offer fractional shares.
Automatic investing: Some platforms let you set up a recurring investment that automatically deploys a fixed amount into your chosen assets on a schedule. Trading 212's "Pies" feature lets you build a target portfolio and fund it automatically. This kind of set-and-forget functionality removes the temptation to time the market and makes consistent investing considerably easier to stick to.
Account Types Available
For UK investors especially, the type of account you hold your investments in has a significant impact on how your returns are taxed. Not all platforms support every account type, so this is an important filter before you settle on one.
Common UK Account Types to Look For
- Stocks and Shares ISA: Lets you invest up to £20,000 per tax year with all growth and income completely free of UK tax. One of the most powerful long-term investing tools available to UK residents
- SIPP (Self-Invested Personal Pension): A pension wrapper that gives you tax relief on contributions at your income tax rate, and keeps your investments growing tax-free until retirement
- General Investment Account (GIA): A standard account with no contribution limits but also no tax protection, meaning gains and income are subject to capital gains tax and income tax
- Junior ISA: A tax-efficient account for investing on behalf of a child, with a £9,000 annual limit. The child gains access to the money at 18
Trading 212 currently offers an Invest account, a Stocks and Shares ISA, and a CFD account. It does not offer a SIPP. Freetrade offers an ISA and SIPP on its free Basic plan as of January 2026. Hargreaves Lansdown offers the full range including ISA, SIPP, GIA, Junior ISA, and LISA. We will go deeper into account types and which one suits which situation in Episode 9.
Platform Quality and Support
Fees and account types are the quantifiable factors, but a platform you find frustrating to use is a platform you are less likely to engage with consistently. A few qualitative things are worth considering before committing.
App and interface quality: For most people investing through a smartphone, how intuitive the app feels matters more than it probably should. Trading 212 is consistently rated highly on both iOS and Android, and offers a clean, fast experience. Hargreaves Lansdown's app is functional and improving, though its desktop platform is where it tends to shine more.
Customer support: Check how you can actually contact the platform if something goes wrong. Trading 212 offers in-app chat with response times typically under ten minutes during UK business hours. Hargreaves Lansdown offers phone support, which is increasingly rare among investment platforms. Freetrade relies primarily on email and community forums, which tends to mean longer resolution times for complex issues.
Research and educational tools: For a beginner, a platform that offers built-in company research, analyst ratings, and clear explanations of what you are buying can reduce the time you spend going elsewhere to look things up. Hargreaves Lansdown offers the most comprehensive research of any major UK retail platform. Trading 212 and Freetrade are more streamlined and rely on you bringing your own research.
A Rough Guide to Who Each Platform Suits
There is no single best platform because different investors have genuinely different needs. Here is a practical way to think about it based on current offerings:
If you are a complete beginner with a small starting amount and want to invest in a small number of broad ETFs with zero fees and fractional shares, Trading 212 or Freetrade are the most cost-efficient starting points available in the UK right now.
If you want access to the widest possible investment universe, including thousands of funds, detailed research tools, and phone support, Hargreaves Lansdown is the most comprehensive option, though you pay for that breadth.
If you have a growing portfolio above roughly £50,000 and are primarily investing in ETFs, a flat-fee platform like Interactive Investor or AJ Bell may work out cheaper than a percentage-based one over time.
If you need a SIPP as well as an ISA in one place at the lowest possible cost, Freetrade now includes both on its free Basic plan as of 2026, which is a meaningful change that many comparison sites have not yet caught up with.
What You Should Remember from This Week:
- Always confirm a platform is FCA authorised and FSCS protected before opening an account
- Fees come in layers: account fee, dealing fee, FX fee, and admin fees. The total matters, not any single one
- Percentage-based fees suit smaller portfolios. Flat fees suit larger ones. Know which bracket you are in
- FX fees are easy to miss and can significantly erode returns if you are regularly buying assets in a foreign currency
- Confirm the platform supports the account types and investments you actually want before signing up
- App quality, customer support, and research tools matter more to some investors than others, be honest about what you will actually use
- Consistency of investing matters far more than which platform you choose
Your Action Step This Week
Take the account type you know you need (most UK beginners will start with a Stocks and Shares ISA) and use a comparison site like MoneySavingExpert or Which? to line up the platforms that support it. Then apply the fee framework from this episode: work out what you would actually pay in account fees, dealing fees, and FX fees given how often you plan to invest and in what currency. The cheapest headline option often looks very different once you factor in all three layers.
