What is an investment platform?

An investment platform may also be known as a fund supermarket as it offers a single place to search and invest in shares and investment funds. This can include a share dealing account and a fund dealing account. They are online or app-based services that allow you to keep all your investments in one place, including your trading history and investments you have bought or sold.

Investment platforms are in two broad groups, those that allow you to decide on the specific investments you will make or those that will create a portfolio or wrap investments together for you based on your investment objectives and attitude to risk.

The investment platform selects which investments it will have available. They usually offer share accounts and trading accounts, and the opportunity for you to manage investments in wrappers such as stocks and shares ISAs, Lifetime ISAs, Junior ISAs and self-invested personal pensions (SIPPs) (pension funds).
Many investment platforms will also provide news, interactive tools and forums to their clients. The idea of using an investment platform is that you have control over your investment choices and can tailor these to suit you. However, this means all your investments are made on an ‘execution only’ basis, making you solely responsible for these choices and you will have no protection or comeback if you incur any losses.

You can also choose to use the investment platform to add funds to ISAs and SIPPs.

What types of investments are available on an investment platform?

Investment platforms usually offer the following range of investment choices:

Shares – These are investments made in individual companies. Having shares in a company means that you own a part of it. If the company does well, the price for individual shares rises and you make a profit, whereas bad performance means the share price will drop, reducing your profits or causing your shares to be worth less than you originally paid for them. There is even the possibility that you could lose all your investment.

Funds – These are a very common way of investing. Investment funds pool individual shares, bonds or both that have a common ‘theme’. The individual parts are called units. The theme can be quite wide-ranging. For example, you might invest in a fund that is specific to a region such as Europe or Asia or an individual country, such as Germany. Or you might pick a fund that is investing in a commodity, such as oil, gold or one that invests in green technologies – in fact almost anything you can think of. However, there is still the possibility that you can lose all your money.

Bonds – These are where you are lending money to a company or even Government (Government bonds are called gilts). In return, you will be paid interest on the loan. Of course, some companies (and Governments) are more stable than others and bondholders are much further up the list of investors to be repaid so the risk is less. However, you should always be aware that there is still the chance you could lose your whole investment.

How to choose the best UK platform for you

  • Check that the platform offers the type and range of investments you want to make
  • Check the charges are sensible for how frequently you want to trade – i.e. if you want to trade frequently are the costs prohibitive or is there an inactivity fee if you may not transact very often?
  • Consider a model portfolio where the investment platform chooses your investments based on your attitude to risk and investment needs

How safe are investment platforms?

When you invest into an investment platform, your investment is placed into a ring-fenced account held with a custodian. The custodian is a separate entity to the investment platform and is usually a large bank. The custodian makes sure that your investment assets are not muddled with those of the investment platform. This means if the platform fails and falls into financial difficulties, your investment assets will remain separate and cannot be used by the platform, for example to pay its debts.
If the custodian was to fail, then investments would be protected under the rules of the Financial Services Compensation Scheme.

Furthermore, investment platforms are regulated by the Financial Conduct Authority (FCA). You can check if the platform is an authorised company by looking at the FCA register. The regulator is responsible for making sure investment platforms adhere to marketing and advertising rules about financial promotions and that they conduct their business to the required regulatory standards.

Note: there is no protection against poorly performing investments. As you have made all your buying decisions on an ‘execution-only’ basis, you are responsible for these choices.

What do I need to think about when choosing an investment platform?

There are three main areas you need to consider when choosing which investment platform is best for you. These are cost, access methods available and the total value of your investments – this last one is closely allied with costs, so we’ll tackle those together:

Investment platform costs and portfolio size

The smaller your trading portfolio, the more you need to focus on costs. If you have a modest portfolio – say up to £5,000 – then you’ll want to ensure that any profit you do make is not immediately gobbled up by trading fees and monthly costs.

As outlined above, every investment platform is subject to differing fees and charges. Some will charge per trade, some by flat fee, others on what investments you are selling and finally some will charge you a percentage of your total portfolio value.

Those who are irregular share-dealers or those with a smaller pot of investments should look carefully at costs and make sure that your profits are not wiped out by the cost of an expensive trading platform.
You might want to remember that different investment platforms will give you different investment options, so this will influence the choice that an individual will make. A more experienced investor will probably seek the widest range of investments, whereas for a less experienced investor, a more limited choice may still be acceptable.


The old practice of calling your stockbroker every time you wanted to make a trade is long gone. Now, most people will happily buy and sell through an online provider – either through a smartphone app or via an online portal.

Choose an investment platform that suits the way you feel most comfortable trading with. For beginners, you may want a platform that provides lots of ‘hand-holding’ and tools that enable you to make better decisions, while experienced traders might prefer something that is more responsive.

Next, consider which platform matches how you want to manage your portfolio. Online share-dealing via a laptop or home PC is great if you prefer larger displays and you don’t envisage wanting to do much trading while on the move. Apps have the advantage of allowing you to access your platform while out and about (providing you have a decent 4G signal) but the display is markedly smaller than if you use a conventional home computer.

Investment platforms FAQs

Do I have to pay for an investment platform?

Yes, but how you are charged will vary between platforms. Some investment platforms will charge you every time you make a trade (i.e. when you buy or sell investments), some will levy a flat fee every month or year and others will charge based on how large your total investment is. Some will not charge you for fund dealing at all but might levy an ongoing administrative fee.
Essentially, there are many different pricing structures, so you will have to do some homework as to which is the cheapest or best value depending on the size of your investments and how often you anticipate trading shares, funds or bonds.
Most investment platforms will charge you an exit fee if you decide to leave, so this should be balanced against the gains to be had from introductory bonuses being offered if you decide to move.

Do I need a lot of money to start using an investment platform?

Not necessarily, you can start with as little as £25 each month and use this to start investing into shares or investment funds. This allows you to drip feed money into your fund and build up your portfolio over time.

I keep seeing 'execution-only' - what does this mean?

Execution-only means that you will buy and sell shares or invest in the stock market without any advice or guidance. Therefore, you will have to rely on your own knowledge and/or research when making a trading decision and are responsible for your investment decisions.
