The Cheapest fund platforms for Stocks & Shares ISAs for most people

The cheapest fund platform will depend on the size of your investment and how many trades you make on an annual basis. Below I have calculated the cheapest fund platforms for an ISA investment.

So assuming that you plan to invest the full annual ISA allowance of £15,240 (2016/17) into funds and make 10 fund switches a year. The top 4 cheapest ISA providers platforms are:

Cheapest Stocks and Shares ISA providers

Stocks and Shares ISA provider Year 1 cost Annual Cost
Charles Stanley Direct £38 £67
TD Direct Investing £46 £57
AJ Bell Youinvest £53 £112
Fidelity £53 £66

Comparison of stocks and shares ISA & SIPP investment platforms

Of course, most investment platforms allow you to invest via a Stocks and Shares ISA as well as a SIPP. So there are cost and admin efficiencies from using the same fund platform for both. At this stage you may not know whether you want to invest your money via a SIPP or an ISA. Or you may plan to start saving into a pension (SIPP) in the future. So it may make sense to ensure that the platform you choose is the cheapest for investing in both an ISA and a pension. Below is a comparison showing the cheapest investment platform for both Stocks and Shares ISA and SIPP investments.

To produce the table I compared both the SIPP charges and the Stocks and Shares ISA charges across the market assuming an initial lump sum investment of £15,000 into a Stocks and Shares ISA and an initial investment of £5,000 into a SIPP. I have allowed for a maximum of 10 fund switches per year:

Cheapest combined SIPP & ISA providers

SIPP & ISA provider Year 1 cost Annual Cost
AJ Bell Youinvest £65 £134
Fidelity £70 £87
Hargreaves Lansdown - (see best buys section below) £90 £164
TD Direct Investing £156 £117

Best buys – Stocks and Share ISA providers

Of course it’s not all about costs as I explain later in the section the ‘things to consider when picking the best fund platform’. Below I provide a roundup of our best buys for ISA beginners and the best overall fund platform for your Stocks and Share ISA.

Overall best buy Stocks and Shares ISA

Hargreaves Lansdown Vantage ISA – provides the best combination of cost, investment fund choice, customer service, online functionality and tools of all the providers out there. Unsurprisingly its the most popular Stock and Shares ISA in the UK and has won numerous industry awards.

Best buy Managed Stocks and Shares ISA for beginners

Moneyfarm –  provide the cheapest discretionary investment service (which means that they make the investment decisions for you) in the market for under £15,000. in fact they will manage £15,000 of your money free of charge. The only cost is the cost of the underlying exchange traded funds (ETFs) which they purchase. Think of it like enjoying the cost savings available to DIY investors without having to run the money yourself. No one else in the market offers this.

Important things to consider when picking the best fund platform

With the rise in DIY investing many investors are now looking to maximise the return from their investments by using a fund platform (also known as an investment platform) to manage their investments themselves.

What is an investment platform?

An investment platform (also known as a fund platform or a fund supermarket) is an online shop where you can buy, sell and hold all your investments in a tax efficient wrapper such as a Stocks and Shares ISA or a SIPP (Self Invested Personal Pension). Fund platforms will have their own Stocks and Shares ISA (often called an Investment ISA) as well as SIPP product. Think of these like boxes into which you place your investments (funds). While the way these products work are the same across the various investment platforms there are distinct differences, such as the number of funds available and the charges that are applied.

Therefore when selecting the best stocks and shares ISA provider that suits your needs it is important to read the below list of the things to consider. The best investment platform for one investor is not the necessarily the best for another investor.

Two things to check to find the best Stocks and Shares ISA

Whether it is a wider choice of investment types, investment tools, research, model portfolios or ease of use on a smartphone every fund platform will offer something different. It makes sense, therefore, to do some research on a number of investment platform providers before you choose the right investment platform for your needs.

1 – Make sure the fund platform provides the investment choice you require

Many people will start looking for an investment platform when they want to invest in a stocks and shares ISA as they search for a better return on their investment. However over time the same person may want to invest beyond the limits of the annual ISA allowance and, say, start providing for their retirement by starting to invest in a SIPP or start a Junior stocks and shares ISA for their children. It makes sense, therefore, to use an investment platform which will be able to provide a service that can grow with your investment needs over time.

2- Always check out the range of charges

The aforementioned Stocks and Shares ISA comparison tool will calculate the cheapest ISA provider for you based on the assumptions you input. However, it is worth familiarising yourself with the full range of charges that an investment platform will apply for the administration of your investments. Some will only be applied if you decide to move your money elsewhere, which the tool won’t include.

Administrative charge

This is the basic charge for use of the fund platform and will either be a flat fee or a percentage fee, which is dictated by the amount of investment.

Dealing fees

These are fees charged every time you buy and sell funds. The more you switch your investments between funds the more these fees will mount up. Most fund platforms don’t charge for fund switches but make sure you check.

Fund manager charge

This is strictly speaking not a fee charged by the fund platform but one charged by the fund in which you invest. Some of the larger investment platforms (such as Hargreaves Lansdown) will negotiate a reduced fee with a fund manager due to the high level of business that is transacted in that fund. So it is worth comparing the fees charged on your desired funds across different platforms.

Transfer fees

If you want to move your investments from one platform to another then the platform you are leaving may charge you a fee for doing this.
