Stocks and Shares ISA – 2026 perspective

Interest rates have been pretty appalling for years now. Due to various reasons, like Covid, the Ukraine War and now the Iran War, keeping a Cash ISA at anything near the inflation rate is hard work if at all possible.

Why is Inflation Important?

Inflation is, in simplified terms, the yearly rate at which everything gets more expensive. The Bank of England try to keep this at about 2.5% per year, but we have seen much higher.
If everything is more expensive, you need more money to buy everything.

Many companies have annual pay reviews and often you will get about 2.5%. This is in recognition that without these you would not be able to continue buying what you do now… or to put it another way, you would be getting paid exactly the same as everything gets more expensive. This has the same result as taking a pay cut, your pay is worth less than it was as you cannot buy the same amount as you were able to.

The same here applies to any money you hold. If you hold £1 and the price of a loaf of bread today is £1, you can buy it. If you held on to that pound for a year, the loaf of bread would cost about £1.03. A year later you cannot buy that loaf of bread anymore.

If you have £1,000 in savings, after a year you need that to be £1,025 to have the same buying value. This is the 2.5%.
So, you need a bank account that pays 2.5% per year for your money to keep its value. Let me repeat this, you earn nothing, it just keeps its original value.
Many Cash ISA’s are not even giving 2.5% and this is why inflation it important.

Stocks and Shares ISAs

There are 2 types of ISAs in the UK. Cash and Stocks and Shares (S&S). While both are ISAs (tax free individual savings) that is where the similarities end.
Cash ISAs are a standard bank account where you always get back exactly what you invest, with some interest.
S&S ISAs allow you to invest in… Stocks and Shares. Historically over a 7 year period, an S&S ISA following a global index fund has made about 8% per year on average, much higher than Cash ISA rates.  Higher rewards do come with higher risks.

Martin Lewis has a great video from his show on YouTube where he explains how impactful S&S ISA’s can be, and the risks involved. Below is a link to the part where he answers a question from the audience and then talks about investing:

I recommend you view the whole video, but the Stocks and Shares ISA part explains enough and much better than I could.

How to open a Stocks and Shares ISA – probably not with your bank

Please don’t skip the video from Martin Lewis above.

NB: Nothing on this website should be considered financial advice.

Opening an S&S ISA with your bank will probably the easiest way to do this, but will most likely be the most expensive way. Banks offer Stocks and Shares ISAs, but many have high fees. If you do this, please make sure you look at the fees and exactly what you are investing in. Often they will take more fees and have worse performance than simply investing in Global Index ETF… which is really easy.

There are a number of platforms for investing that have very low fees, but the one I personally use and seems to get good reviews across the Web is Trading 212.
I have by far found this to be the most straightforward to use than anything else I have tried, however I strictly use this only for ISAs and none of there other investment products.

The process to sign up is incredibly easy. They have a website and app. I personally use the app. Here is a link to their ISA page:

Global Index ETF

So, let’s assume you have an S&S ISA. You have deposited some cash. Now you need to pick something to invest in.

You could pick a single company to invest in. This might work out great if they do well, but if they don’t you could lose money. (you could lose money on any investment, if this is not clear, go back and watch the video from Martin Lewis).

The safer approach is to invest a little in many companies. Hopefully they all do well, but if some don’t, as long as you have more high performance companies you will still make money overall. So which ones to pick? How many? What countries? Industries? This is where a Global ETF comes in.

Investment companies like Vangaurd will offer various ETFs that track companies and assets like gold. A Global ETF tracks companies and as the name suggests covers all countries and industries.
The one I personally invest in is this one:

FTSE All-World UCITS ETF – Accumulation (VWRP)

Please make sure you follow the link and read about it. The fees to Vanguard for investing in the ETF are listed, as is the past performance and much more.

Investing in the VWRP

Assuming you have yourself an S&S ISA with a platform like Trading 212, you should be able to search for VWRP, which is the ‘Stock Ticker’ for the Vangaurd FTSE All-World, view all the information about it, and also invest in it by buying shares.

That’s really all there is to it. (I am not going to cover Trading 212 functionality here).

What Next?

Leave it well alone! Forget about it for a few years.

Once you have bought shares, you can watch the value in the app. As mentioned before, this can go down as well as up. The general recommendation is you only invest what you can put away for a number of years, around 7 seems to be the accepted wisdom, and this is a long enough time to weather any dips and hopefully get more highs.

Investing in an S&S ISA should NOT be viewed as a short term investment. Seriously, invest and then forget about it. This way you are less likely to panic. Having been invested for a while now, there can be big swings caused by global economic and political activity, but these swings can go both ways.

As always, do your own research.

Hopefully this has given you enough information to get started and covered how I have approached this, but there is more to learn and understand. Here are some additional links that may help:

ISA Rates vs Regular Savings Rates – Calculations

Seems like an odd post title, but it is the best I could come up with, thinking about what I might search for. So what is this post about?

ISA stands for Individual Savings Accounts, and is a government backed tax free savings account for persons in the UK. There are 2 types of ISA’s available, Cash and Stocks and Shares. They both share an investment limit of £20,000 per tax year at time of writing. The key thing here is that you do not pay any tax on earnings (interest).
You can read more about ISAs here: Individual Savings Accounts (ISAs): Overview – GOV.UK

In this post I am going to share a simple method of comparing rates between a Cash ISA and a regular savings account. Why does this matter? The tax. The rate you are earning in a regular savings account is subject to tax, therefore you don’t actually earn that amount so comparing an ISA rate to a regular savings rate is not a true comparison.

Luckily comparing is easy. The TLDR… multiply the ISA rate:

x1.25 if you are a standard rate tax payer
x1.66 if you are a higher rate tax payer

Here is a simple example. If you find an ISA rate of 4% and are a standard rate tax payer, multiply it by x1.25, which equals 5%.

How does this work?
Lets assume you have £2,000 in regular savings earning 5% per year. After a year you will have earned £100 in interest. However as this is taxable earnings, as a basic rate tax payer you will be charged 20% meaning you will only earn £80 after tax. £80 interest on £2,000 is actually 4%.

So why multiply 1.25 as a standard tax payer? Well actually this is just one way to calculate it, and I actually prefer a different way as it makes more sense in terms of the rate of tax you are paying, which could change.
My preferred way to calculate this would be to divide the ISA rate by 1 minus your tax rate. So for a basic tax payer of 20% it would be 1 – 0.20 = 0.80. Using our example above, 4% divided by 0.80 = 5%.
If you were a higher rate tax payer it would be similar. 1 – 0.40 = 0.6, therefore 4% divided by 0.60 = 6.66%

So, there it is…or is it? For comparing rates that is pretty much it except for one important element:
Tax on savings interest: How much tax you pay – GOV.UK
If you earn less than £17,250, you can the difference between your salary and this figure in savings interest tax free, up to a maximum of £5,000.
Furthermore if you are a basic rate tax payer, you can earn £1,000 of interest tax free, and for higher rate earners its £500 tax free.
If any of the above apply for you, you wont pay tax on the interest you earn anyway, so you wont benefit from the ISA being tax free.

In the end you need to be aware of the best options for saving, which can be tricky. The biggest benefit of an ISA is that the money in the ISA earns tax free forever. As always DYOR, but hopefully this post at least highlights some of the things you should think about, and a neat calculation for comparing ISA rates to regular savings rates.
