What is the Minimum Deposit to Open a Stocks & Shares ISA?

If you’re just starting out on your investment journey, you may be investing with little money each month, or have a small lump sum to begin your nest egg. It’s important that you can compare stocks & shares ISA minimum deposit limits, to find a provider who will help, rather than hinder your first steps.

Finding an ISA provider which will accept a tiny deposit is only the first step.

In my guide How to invest £1,000, I explain that investing fees can also make-or-break your portfolio. Your investments won’t grow if they’re being plundered by fees that were designed for much larger portfolio sizes.

So in this article I will answer the question of what is the minimum deposit allowed to stocks & shares ISA, and how to find the best stockbrokers in the UK which will keep fees low to help your money grow.

Scottish Friendly – £10 regular contribution

Lowest deposit to open stocks & shares ISA

An honourable mention goes to the Scottish Friendly Stocks & Shares ISA which allows investors to sign-up with a regular contribution of £10 per month. This was also quite a rare offering.

Other stocks & shares ISA providers asked for a minimum deposit of £25 – £100 in most cases. The smallest amounts tended to be regular investment schemes, where you sign up to a monthly direct debit for the small sum. A regular investment direct debit is not generally an obligation, so it can be cancelled if you wanted to stop investing further money into the ISA. However, it’s best to always read the terms and conditions for the ISA you are interested in, as T&Cs can vary.

Its also worth noting that the Scottish Friendly stocks & shares ISAs come in different flavours, with some tied to funds that carry some higher charges, such as the Unitised With-Profits fund which has a charge of 1.5% per year, which is high for an equity fund and might not be the best fund to invest in for the long term for this reason. The cheapest equity ETFs have an annual charge of less than 0.2%.

Therefore certainly do your research when choosing what to invest in now and be sure that you understand the total charges that will be deducted from your investments and account each year.
