5 cheapest DIY investment platforms for your £20,000 ISA

|

In this article we review the 5 cheapest investment platforms for your £20,000 ISA. Many of you will think that £20,000 is a lot of money as a first-time investment and you’d be right, but it’s the annual limit you can invest in a tax-free ISA.

An ISA is effectively a tax-break allowing your investment to avoid any tax as it grows, like capital gains or dividend tax, so when it’s time to cash in, the money is all yours.

Most online investment services allow you to invest much less than £20,000, both as a one off or as a monthly investment. Typically, providers let you invest £500 as a one-off or £25 per month, helping you start your investment journey more affordably.

We want you to choose the very best investment provider for your needs, because making the wrong decision now can cost you thousands of pounds in the longer run.

Which provider to choose?

If you’re looking to start investing now, make sure you do some research before you leap. That’s where Compare+Invest comes in, as it can be really difficult comparing the service and costs of the 50+ online investment firms out there. Here, we’ll look at the cheapest Do It Yourself investment platforms – where you choose the investments and manage your choices on an ongoing basis.

It’s not scary to do and most providers offer ready-made solutions for those who feel a little daunted at picking funds and shares. Investment platforms all charge a fee for their services on top of the cost of the fund itself.

We will be comparing this annual administration cost in this feature and remember that as the value of your investments rise, so too will your annual charges, unless you pick a fixed-fee provider like interactive investor.

And of course, if you’re looking at investing a different amount, whether it’s for a financial goal or retirement, there are various calculators to help you at Compare+Invest.
