Clare says

You’ll get oodles of choice and top-tier features with Saxo, making this a more powerful app than many others on our list. But a clever design makes the investor-targeted platform – SaxoInvestor – accessible for everyone, including inexperienced investors.

Minimum monthly custody charges and inactivity fees have recently been scrapped at Saxo, making fees much more attractive and simple to work out.

Simple and very cheap way into investing.
My focus is keeping costs to a minimum

With investments, your capital is at risk. This could mean the value of your investments goes down as well as up. T&Cs apply.

Clare says

With InvestEngine, low-cost and easy marry up beautifully to create an ideal option for absolute beginners and those just looking for simplicity.

There are no annual fees to worry about if you’re a DIY investor, zero dealing fees or commissions to consider, and no exit or withdrawal fees either. You will still need to pay ongoing fund fees, which vary according to the fund you choose, but these are standard costs whatever provider you choose. If you choose to have a managed fund, there’s a fee but it’s a very reasonable 0.25% p.a.

Exchange traded funds (ETFs) are traded in much the same way as stocks. Instead of an individual stock, however, you own a basket of different assets which track the performance of a particular index or market. ETFsinfo are a simple way to get yourself a ready-diversified portfolio. But the fact there are no individual stocks on the menu at InvestEngine, will mean it’s not right for stock pickers.

No account fees, platform fees or subscriptions for DIY investors

InvestEngine does charge a very reasonable 0.25% annual fee if you want a 'Managed' portfolio, but for DIY investors, the only costs are ongoing fund fees which vary from fund to fund and are par-for-the-course whichever provider you choose.

ETFs are low-cost and well-suited to beginners

Most ETFs are passively managed, meaning they aim to track an index (like the S&P 500) rather than trying to beat it. This requires fewer research analysts, portfolio managers, and trading costs, making them relatively low-cost funds to own. They are also often 'ready-diversified' so it's easier to stay out of the trap of putting all your money into a narrow selection of stocks.

This is 'the ETF platform'

There are over 830 ETFs to choose from at InvestEngine, incorporating a wide range of asset classes, markets and sectors including leading global indices, thematics such as AI, robotics and clean energy, ESG, and emerging markets.

Reasons to use

  • No account fees or trading costs
  • Lowest cost SIPP and ISA on the market
  • 830+ ETFs to choose from
  • Fractional investing available
  • DIY and Managed options
  • Welcome Bonus of up to £100

Reasons to avoid

  • Investment options limited to ETFs
  • No chance to pick individual stocks or bonds

Cost Comparison

Fees can substantially eat into your investment gains and are therefore worthy of careful consideration when selecting which platform to invest with. Below I have provided you with a visual aid of how these platforms would compare on cost.

Remember, that fees should not be your only consideration. The main purpose of investing in an investment platform is to grow your money as much as possible. In this respect, the assets offered, and the performance of the ready-made portfolios on offer will also be relevant.

Ready-made portfolio returns

If you don’t have the confidence/time to choose your own investments or are simply seeking a more ‘hands-off’ approach, then you may want to consider the fully managed portfolios on offer.

But how do you know that the portfolio you are considering will provide you with decent returns? The answer is… you don’t! However, we can look at how well these platforms have managed their portfolios in the past 5 years. As you can see, results have been variable, but try to remember that the eToro option is very undiversified and therefore presents a big risk to your capital.

Ready-made portfolios

Managed or ready-made portfolios provide a hands-off alternative for investors lacking the confidence to choose their own investments. However, whether this is a good option or not comes down to the returns achieved. Whilst historical returns won’t guarantee future returns, they can provide an indication of how successfully the portfolio is being managed.

We have done all the analysis on ready-made portfolios for the past 10 years where information is available and pitched them against each other as a direct comparison. Head to the this page for comprehensive results.

How do you choose the best platform for you?

1. Your level of experience is important! The app you choose must be appropriate for your skill level. You don’t want to feel overwhelmed by features that are only needed if you’re a pro-level trader, or equally under-resourced by a basic, beginner-level platform if you’re more experienced.

2. Pay attention to fees. Large portfolios will be best served with a flat fee structure, while smaller ones could benefit from percentage fees or zero fees. Even small differences on fees can add up over time and really eat into your returns to compare costs on the types of investments and transactions you’re likely to be making. Don’t forget to include: subscriptions/account fees, trading (dealing) fees, FX fees if you’ll be trading non-UK assets, withdrawal fees, and fund fees (although these vary very little across platforms as they are charged by the fund providers).

3. What sort of tools and resources do you need from your investment app? That will largely depend on your experience level.

FAQs

Consider three things when choosing an investment app: 1. What level of investor you are (beginner, experienced, pro) and therefore what kind of features you're likely to need; 2. How much you will be investing and whether their fee structure benefits smaller-scale or larger-scale investors; 3. What the fees are and whether you could be saving money by choosing a different provider. If you're planning on using a ready-made portfolio, consider the past performance of the platform's portfolios (although past performance is not a guarantee of future performance).

Always choose an investment platform that is authorised the Financial Conduct Authority (FCA). Choosing a platform registered with the FCA means your money is protected by strict regulatory standards. Never use an app that is not authorised by the FCA. In addition, if the platform is FSCS protected, your money is safeguarded up to £85,000 if the provider fails, giving you a powerful layer of financial security and peace of mind.

You definitely don't need a lot of money to invest! Many investment platforms allow you to start investing with just £1.
