Some brands use fee structures that work better for those with smaller portfolios, while others use fee structures that benefit larger portfolio-holders.
It really pays to know the difference.

Freetrade does exactly what it says on the tin – offers free trading (and investing). If it serves your needs in terms of the investment assets they offer, and you stay away from US stocks where FX fees are on the high-side, then it’s possible to open either a general investment account or a Stocks & Shares ISA and buy and sell investments for zero fees. That’s no account fees, no subscription fees, and no trading fees.
That only applies if you stick with the free ‘Basic’ account, however. There are two other account types: Standard (£4.99 p/mo) and Plus (£9.99 p/mo). These come with better rates of interest on uninvested cash, lower FX fees (making US stocks more affordable), and access to mutual funds. But as these are flat-fee subscriptions, they are expensive if you’re only investing small amounts.
It’s the free account that makes Freetrade a staggeringly cheap way to build up an ISA or general investment account.
Use this if
You only want to invest in UK or European shares or ETFs, and you’re looking for a free, simple Stocks & Shares ISA or general investment account.

InvestEngine regularly appears on our lowest-cost recommendation tables. There’s a no-charge Stocks & Shares ISA, a no-charge general investment account, and it is one of only two providers (the other is Prosper) to also offer a no-charge
Essentially, if you’re wanting a very low-cost personal pension or ISA, InvestEngine is definitely one to consider.
Where you might find a problem, however, is in its range of investment options as InvestEngine clients can only invest in
In terms of other possible costs? As there are no individual stocks on offer, you don’t have to worry about
You will need at least £100 to get started though, considerably more than many other providers ask for.

Robinhood is undoubtedly a very cheap platform on which to trade US stocks. Possibly THE cheapest. The only fees you’re really paying are the 0.03% “third party” fees to convert your GB pounds into US dollars when you deposit money, and visa versa when you withdraw it again (- all funds must be held in US dollars on Robinhood).
The major downside, however, is that there is currently no Stocks and Shares ISA, so you can’t protect your investment income from tax. There’s also no personal pension account. And there is no alternative to buying US stocks at present either: no ETFs, no mutual funds, and no stocks from the UK or rest of the world. So, that’s pretty limiting.
But US stocks is where it’s at for you, then this is possibly the cheapest place you’ll find to buy and hold them.

You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.
If you look at our charts ranking providers from cheapest to most expensive below, you’ll notice that XTB only appears when you’re investing in UK stocks.
When just looking at UK stocks, XTB is undoubtedly cheap. But if you’re investing in non-UK assets, you’ll need to factor in the 0.50% currency conversion (FX) rate that’s around about average (0.50%) which pushes costs up.
If you can avoid the FX fees though, it’s a free account. There are no account fees, there’s no commission to pay when buying or selling investments (unless you’re trading over EUR 100,000 per month!), and no withdrawal fees.
XTB is has traditionally been a trading platform, so it is more complicated to use than the investment-focused platforms. That’s because, with a trading platform, there will be a wider range of tools for those trading more complex instruments to use. If you’re a beginner, that can make the platform feel confusing and overwhelming.
Having said that, XTB has done much in recent months to make it a more comfortable space for investors too. There’s a separate price list for those just interested in stocks and ETFs, which is a great idea, as once pricing involves CFDs, options or futures, things become a whole lot more confusing.

– No-fee investing & a free SIPP make this a very cheap platform.
Fee-free ISA and self-invested personal pension (SIPP)
Fund fees refunded
Capital at risk
Prosper is a relative newcomer, having only launched in 2021, but it’s made waves with a refreshing proposition that includes zero fees on ISAs and – very unusually – also
Even more unusually, there are 30 funds where Prosper will refund you the fund fees, meaning this can actually be a completely free ISA or SIPP. This differentiates Prosper from InvestEngine, where fund fees still apply although it must be said that fund fees can be kept very low (funds start from 0.03% at InvestEngine) and the fees come straight from your investments so it’s not an upfront cost.
You can start investing from just £1, and there’s a good choice of funds (190+) including 25 ready-made portfolios. You won’t be able to stock pick here, as the only investment options are mutual funds and ETFs. But, that’s if you’re wanting to keep it simple, that’s plenty, and it’s slightly more choice than InvestEngine offers (just ETFs).
Prosper is also refreshingly transparent over how they make their money (they keep the interest on any uninvested cash you keep in your account), so you’re not left worrying about whether it’s too good to be true.

Total fees may comprise of:
If you are buying stocks that are denominated in another currency from your own, you will also need to pay:
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 small 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. Conversely, you’ll find that fixed fee structures are disproportionately expensive for those with lower portfolio values. So, if you’re starting small, look for platforms that operate percentage-based cost models.
There are some exceptions, however. Freetrade operates a fixed fee model, but also offers a fee-free basic account. Prosper, Trading 212, and iWeb also don’t charge annual account fees. If you don’t plan to trade often, and therefore won’t incur trading costs, then a platform that let’s you hold your money for free could be a great option.
Beware the trading costs
Some providers offering low annual fees pile the costs on in other areas. As you’ll 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.
Another way to avoid annual fees
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.
Of course, fees aren’t the only consideration when selecting an investment provider.
