InvestEngine is a great option for those who are just getting started and want as few decisions as possible.

Because InvestEngine only deals in 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, you choice is limited and your portfolio will automatically have some degree of Diversification is an investment strategy that involves spreading your money across different assets to reduce risk. The idea is not to place all your eggs in one basket. The benefit of this approach is that when one losses are felt by one type of investment asset class, it is rare that other asset classes are equally impacted. diversificationinfo built in.

On cost, it’s hard to beat InvestEngine as you’ll see from our price comparison tables below. That’s because there are no annual fees if you’re a DIY investor (and only 0.25% p.a. to pay if you want a [sc_Managed Portfolio word=”Managed Portfolio”]), no dealing fees or commissions at all, and no exit or withdrawal fees either. You will still need to pay ongoing fund fees, which come in a range of prices, are taken from your portfolio directly, and is the case whatever provider you go for.

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 fees
  • 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

  • £100 min. initial investment
  • Investment options limited to ETFs
  • No chance to pick individual stocks or bonds

Clare says

Freetrade is one of the best ‘simple investing’ apps on the UK market. It offers more choice than InvestEngine in that it also offers stocks (and not just ETFs), meaning you can add shares in individual US and UK companies to your portfolio too. The app is cleverly designed, however, to help new starters navigate their way through the research and get invested without the overwhelm that can come with more complex platforms.

On price, Freetrade performs exceptionally, often topping our tables of low-cost providers. That’s thanks to zero account fees (even on their Stocks and Shares ISA), zero withdrawal fees, and zero trading fees on stocks, ETFs and mutual funds. Just watch out for those currency conversion fees, which are on the high side if you’re buying non-UK stocks through a ‘Basic’ account.

You can also trade fractional US shares on Freetrade – which makes it possible to buy a slice of a single share on stocks with big price tags that might otherwise be unaffordable.

'Freemium' price model

Use the free 'Basic' account and there are no account or subscription fees to pay for a Stocks and Shares ISA or General Investment Account. If you want to level up to a paid account, you can access a wider range of assets (including mutual funds), lower FX fees, higher interest rates on uninvested cash, and a personal pension product

No minimum deposit + fractional shares

Start investing with just £1 and as Freetrade offers fractional investing, you can get less than one whole share, meaning you won't need hundreds of pounds to buy shares in popular and expensive companies.

Award-winning app

Freetrade's app is cleanly and smartly designed to be accessible for brand new investors and those just wanting to dip their toe into the markets. It won 'Best Investing App' in the 2025 Good Money Guide Awards.

Reasons to use

  • No minimum deposit
  • Commission-free trading
  • Zero-account-fee ISA
  • Well-designed, user-friendly trading platform
  • US fractional shares available
  • No inactivity or withdrawal fees
  • Up to 3.50% interest on cash
  • Voted Best online trading platform six years running at the British Bank Awards

Reasons to avoid

  • Mutual funds only available on paid accounts
  • FX fees are on the high-side unless you’re a Plus account-holder
  • Plus account costs £9.99 p/mo
  • Selection of stocks and ETFs on offer isn’t as large as some other providers
  • Just 1.00% interest paid on uninvested cash in the Basic account
  • App-only

Zero-commission investing, ultra-low A foreign exchange (FX) fee is added to all trades involving foreign currencies.

Understanding fees

Total fees may comprise of:

  • Service / Annual fees
  • Ongoing fund fees (for funds)
  • Dealing fees

If you are buying stocks that are denominated in another currency from your own, you will also need to pay:

  • Foreign exchange (FX) fees

There may be other costs, such as taxes and levies, that could also be applied, but we haven’t included these are they are applied universally, and don’t change between providers.

What fee structures work best for large portfolios?

Not every provider charges in the same way. Some providers use a flat-fee subscription model, while others charge fees as a percentage of the total value of your investments. Flat-fees tend to favour larger portfolio holders as they don’t increase, no matter how much your portfolio grows.

Not many providers use a fixed fee model, but the following do:

However, in recognition that large portfolio-holders will be paying a high price within percentage models, many percentage-based providers cap fees, which in effect turns those maximum fees into fixed fees. That can also make them good value for large portfolio-holders.

Providers that apply a cap include:

Other platforms offer reductions for large portfolios on their percentage fees.

Extra costs

It’s not just annual fees you need to factor in, however. Some providers offering low annual fees pile the costs on in other areas. As you’ll be able to see from the fee comparison charts, providers with the lowest annual fees often become high-cost providers when FX fees and/or dealing fees are taken into consideration.

So, it’s important to understand all charges that are levied by providers when making a decision on where to invest.

One other thing to bear in mind, is that dealing fees and FX fees are largely avoidable if you don’t trade often. A buy-and-hold strategy can keep those costs off your balance sheet, and has other advantages too. It avoids falling into the trap of trying to time the market, for example, something that has been consistently shown to be less effective than staying in the market over long periods.

If you do plan to trade regularly, it’s worth asking if your provider offers a Regular Investment Plan, where money is automatically drip-fed into your account every month. In return for this commitment, providers will often waive or discount trading charges. Fidelity and AJ Bell offer this, for example.

It's not all about the fees

Of course, fees aren’t the only consideration when selecting an investment provider.

You’ll also need to think about:

  • If the provider offers the investable assets you want to hold
  • If the provider offers the account type you want to invest in (ISA, Junior ISA, SIPP, general investment account)
  • What customer service is like
  • Whether the platform is too complex for you, designed to suit new investors, or works for a range of experience levels

We’ve assessed all these factors, and more in our full reviews. Simply select the brand name you want to explore from the main website menu.
