The best stocks and shares investment ISA (& the cheapest fund platform)
Readers and journalists often ask me which is the best stocks and shares ISA. The answer depends on your circumstances and whether you want to buy shares, buy investment trusts, buy exchange-traded funds or simply buy unit trusts. This guide will show you how to find the best stocks and shares ISA as well as those ISA providers that can offer advice on where to invest your ISA allowance. I will also highlight the best stocks and shares ISA for tools and functionality as well as the best & cheapest stocks and shares ISA for beginners. If you are simply concerned with cost we also cover the cheapest stocks and shares ISA as well as the cheapest robo-adviser. The full amount you can invest in a stocks and shares ISA is now £20,000 (for both 2018/19 and 2019/20 tax years) and that can be split between shares, ISA funds and cash.

Comparing stocks & shares ISAs
Under the current ISA rules you can choose to invest some of your ISA allowance in a cash ISA and the balance of your ISA allowance in a stocks and shares ISA. However, for the remainder of this article I will assume you are going to invest the full ISA allowance of £20,000 into a Stocks and Shares ISA (also called a NISA)
Step 1 - Do you want to choose your investments or let someone run it for you
There are two options when it comes to investing in a Stocks and Shares ISA. You can choose to pick the underlying investments (funds or shares) yourself or let someone take care of picking and running the investments for you. If you want to have control over how your money is invested then jump to step 2 below. If you'd rather let someone run your money for you at low cost while optimising performance then you would be better off choosing what the press has coined a robo-advisor. Robo-advisers will put your money in a diversified portfolio based on the amount of risk you want to take. They will then manage the investment for you which you can view and monitor online. The 'Best Managed Stocks and Shares for beginners' shown below is a robo-advisor which has manage to combine strong investment performance with low costs. If you just want to pick the cheapest robo-advisor then you can jump to our robo- advisor comparison table using this link.
Steps 2 and 3 below provide further advice for those investors wanting to invest their own money themselves (so called DIY investors).
Step 2- Decide how you want to invest your stocks and shares ISA
If you plan to invest your ISA allowance yourself then when you compare stocks and shares ISAs the cheapest ISA provider or platform for you will depend on what you want to invest in. When you invest in a stocks and shares ISA there are a range of charges. Firstly there is the charge of the underlying fund or asset you are investing in. Then there are the charges levied by the broker or fund platform (often called a fund supermarket). Every stocks and shares investment ISA provider levies different charges based on what you invest in and how much you have invested with them. For example there may be additional charges levied for investing in shares or investment trusts. So what might you invest in?
Most DIY investors will invest in funds which in turn buy shares and other assets, such as corporate bonds. Funds (a term which includes investment trust. unit trusts and ETFs) are called collective investments. They pool investors money together to benefit from economies of scale and then invest that money in assets such as shares or bonds. Actively managed investment funds have a fund manager who chooses the underlying investments. Meanwhile passive investments simply track an index such as the FTSE 100 index using computers. If you are considering investing in funds then I recommend downloading this FREE guide to investing in funds. It's the best guide I've come across on the topic and tells you all you need to know including how to get started with buying funds.
If you want to buy shares within your stocks and shares ISA this limits your choices in terms of which would be the best stocks and shares ISA provider for you. Some stocks and shares ISA providers do not offer the stockbroking facility required to buy shares directly. Investing directly in shares is a riskier investment strategy as while it can be profitable it increases the chances of a potential loss.
Step 3 - More things to check when choosing the best stocks and shares ISA
Once you know what type of investments you wish to buy that makes life a lot easier. If you want to buy shares and investment trusts your options are much more limited. If, like most investors, you want to just invest in stocks and shares ISA funds then you need to consider other factors to screen down your choices. For now we will set cost to one side and come back to it later. Competition among funds supermarkets and online brokers is growing increasingly fierce so costs are falling all the time.
There has been a mini-explosion in new stocks and shares ISA providers, after all it can be a lucrative market if providers get the proposition right. To many of the new online providers that means keeping their own costs low, by that I don't mean the costs you pay but how much time and money they have to spend administering your investments.
As such the level of service some provide is pretty minimal. You need to decide if being able to speak to someone on the phone if things go wrong is important to you. You need to decide whether you want a slick user experience with the ability to buy and sell investments quickly and easily. Would you like to be able to check your investments via your smartphone, if so do they have a smartphone app?
Does the stocks and shares ISA accept transfers in
If you already have an existing stock and shares ISA portfolio you might want to consolidate them all with one provider. If so check what their rules and charges for doing so are.
Tools and research
Some stocks and shares ISA providers offer tools and some research (albeit limited). However most don't. Would you like a tool that can help you to pick the best stocks and shares ISA funds for your objectives? If so check they offer these. I highlight some of the best stocks and shares ISA providers in the next section and detail what they offer.
As mentioned there are a host of charges that stocks and shares ISA providers can levy. They include:
- transfer charges
- dividend reinvestment fees
- buying charges
- selling charges
- fund switch charges
- bid/offer spread
- fund manager charges
- platform charges
- transfer out fees
We include a full comparison of the costs of each stocks and shares ISA provider at the end of this article so that you can find the cheapest stocks and shares ISA for you. However, you shouldn't just focus on cost but instead consider value for money as well as the level of service provided.

Cheapest Robo-adviser (who invest your money for you)
Robo-advice is the term that’s been given to online investment managers which provide an investment product like an ISA where they invest your money for you. Technically robo-advisers don’t actually give you advice but instead they offer a limited number of portfolios (from low risk to high risk) from which you select one. They then invest your money and usually at low cost using exchange traded funds (ETFs). Picking the best robo-advisor isn’t just about picking the cheapest you need to also consider investment performance. The table below gives the cost for each size of ISA portfolio for the list of UK robo-advisers. The cost quoted is the charge applied by the robo-advisor to run your money plus the costs of the underlying investments (ETFs).
|Platform||£5,000 portfolio||£10,000 portfolio||£20,000 portfolio||£50,000 portfolio||£100,000 portfolio||

Best Cash ISA
If you do not have an investment timeframe of at least 5 years (i.e. you will need access to your cash within 5 years) then you would be better off placing your money in a cash ISA rather than in an investment ISA. That is because when you take out a stocks and shares ISA you will be Investing in shares, funds, bonds, investment trust or exchange traded funds (ETFs) all of which carry investment risk and the potential to lose money as well as make it. Below are links to our latest cash ISA best buy tables:
