How to choose an investment platform or broker
Last updated 25 October 2026 · 2 sources listed · Reading time about 3 minutes
Short answer
Compare platforms by how they charge, what they let you hold, how they protect client assets, and how usable they are for your style of investing. Charging models differ between flat, percentage and per-trade structures, and the right one depends on balance size and trading frequency. Check regulation, asset segregation and account types available where you live.
Who this is for: A beginning or switching investor comparing brokers and fund platforms to hold investments in their own name.
What to evaluate
Charging model
A percentage fee penalises large balances while per-trade fees penalise frequent trading.
How to check: Model your likely holdings and trades against each fee schedule.
Regulation and asset protection
Client assets should be held separately from the firm's own money.
How to check: Verify authorisation and the investor compensation scheme that applies.
Investment range
Some platforms offer funds only, others shares, bonds or international markets.
How to check: List what you want to hold and confirm availability.
Account wrappers
Tax-advantaged accounts may be offered only by some platforms.
How to check: Check which account types are supported for your country.
Tools and usability
Research, reporting and a clear interface support good decisions.
How to check: Try a demo and examine statements and tax reports.
Exit and transfer terms
Leaving can involve fees or slow transfers.
How to check: Read the transfer-out policy.
Comparison
| Type | Good when | Watch out for |
|---|---|---|
| Execution-only broker | You choose your own investments | No guidance and easy to over-trade |
| Fund supermarket | You want a wide fund choice in one place | Platform and fund charges both apply |
| Robo-advisor | You prefer an automated portfolio | Limited customisation and ongoing management fee |
| Bank-owned investment service | You value one relationship | Product range may lean toward in-house funds |
| Advisory platform with human guidance | You want personal planning | Higher cost and conflicts to question |

- Leaving idle cash in a platform account that pays little.
Related questions
Are my investments safe if the platform fails?
Regulated platforms are required to keep client assets segregated from their own funds, so your holdings should be recoverable, though processing can take time. Compensation schemes may cover certain shortfalls up to a limit. This does not protect against market losses. Verify the regulator and scheme for your location.
How do platform fees compare?
Platforms may charge a percentage of assets, a flat fee, per-trade commissions or a combination, plus fund charges, so comparisons need your own numbers. Smaller balances often suit flat low-trade-cost models less than percentage models, and vice versa. Build a simple scenario for your balance and activity.
What is a robo-advisor?
It is a service that builds and maintains a diversified portfolio based on a questionnaire, typically using low-cost funds and automatic rebalancing. It suits those wanting hands-off investing. It charges a management fee on top of fund costs, and the questionnaire cannot capture every personal circumstance.
Can I move my investments to another platform?
Usually yes, through an in-kind transfer that keeps holdings intact or by selling and moving cash. In-kind transfers avoid being out of the market and trading costs, but each platform has its own rules and possible fees. Check the process before you commit.

Robo-advisor or self-directed investing: matching the approach to your involvement
Robo-advisors automate allocation and rebalancing for a fee, trading customisation for convenience. Self-directed investing costs less in fees but requires you to choose, rebalance and resist emotional decisions. The choice turns on how much time, knowledge and discipline you bring, and how simple your goals and tax situation are.
Cost factors · Investing platforms
The layers of cost when investing through a platform
Investing costs come in layers: platform charges, fund management charges, trading commissions, currency conversion and sometimes spreads or advice fees. Small percentage differences compound over long periods. Use the regulator-required cost disclosures to total these layers for your own scenario, and recognise which costs scale with balance and which with activity.
Suitability · Investing platforms
Is investing suitable for you yet: questions to settle before you start
Investing tends to suit money you will not need soon, after emergency savings and high-cost debts are addressed, with a goal and horizon you can name. Because values can fall as well as rise, readiness involves finances, timeline and temperament. This is a framework of questions, not a determination for any individual.
How to choose · Savings and deposits
How to choose where to keep cash savings
Choose by purpose and timeline: money you may need at short notice favours instant-access accounts, money with a fixed horizon may suit term deposits. Compare how rates are set and whether they are introductory, access restrictions, deposit protection and tax treatment where you live. A higher advertised rate matters less than conditions that make it apply.
How to choose · Retirement planning
How to choose between retirement account types
Retirement vehicles differ in who contributes, how contributions are taxed, when you can access the money and who bears investment risk. Compare employer matching, tax treatment on the way in and out, investment choice, fees and portability. Rules are jurisdiction-specific, so confirm with your tax authority or pension regulator and consider independent guidance.
How to choose · Current accounts
How to choose an everyday current account
Pick a current account by matching how you actually move money to the account's fee structure, rather than by sign-up perks. Look at what triggers charges, how easily you can reach support and dispute payments, what protection applies to deposits in your jurisdiction, and whether the app and payment tools fit your routine. Perks matter least; reliability and clear terms matter most.
How to choose · Business operations
How to choose a business bank account
Judge a business account on how it fits your payment flows, not only on its monthly charges. Look at fee structure, payment methods and international capability, integration with accounting software, user permissions, deposit protection, lending relationship potential and service quality. Compare a full month of your expected activity against each fee schedule, and confirm what happens if you outgrow the account.
