Are you thinking of selling shares in a company? It is important to understand how to sell shares, what usually prompts this, and what to consider beforehand.

There are various ways to ensure that selling up aligns with your wider investment goals, and there are many avenues for those who want to sell.

Generally, buying stocks and shares is a long-term investment move

How to sell shares

Most people planning to sell shares do so via a UK brokerage or investment platform, which offers the option of selling shares online, on an app or over the phone (the latter may incur extra fees).  

Before selling up, you’ll be able to see how much you’ll receive before proceeding.   

The exceptions to the above are those that own private equity shares and opt to sell them directly to another investor. 

In these circumstances, a brokerage service is not needed, but the private company involved will usually have to approve the sale. 

We’ll now run through below what you must do before selling shares. 

  • Make sure selling shares is right for you: A financial adviser can help you decide if selling shares now aligns with your long-term investment goals.

  • Have a plan of action: You’ll need to consider how selling shares will impact the rest of your investments, including whether you’ll still have a diversified portfolio.

  • Log in to your online investment account: Then, find the shares you want to sell, which you can do online or via an app. Alternatively, you can sell them over the phone.

  • Have a final review before selling: In most cases, you can see how much you’ll get before selling your shares – if you’re happy with the price, go ahead and sell.

When should I sell my shares, and why do people sell them?

There are many reasons why investors might want to sell their shares.

Common reasons for selling include:

💰 Needing access to cash: For retirement, large purchases, or emergencies.

🔄 Rebalancing your portfolio: Selling in one sector to buy into another and stay diversified.

🏢 Company changes you disagree with: Such as corporate restructuring, poor management decisions, or risky strategy shifts.

📉 Sustained poor performance: A company consistently underperforming compared to its competitors.

📰 Sector or market changes: You no longer want exposure to a particular industry or market.

Depending on your own experience, you should consider how valid your reasoning is behind selling up, as rash decision-making and stocks and shares trading don’t tend to go hand in hand. 

So, if you’ve spotted that the share price has dropped in a company you’re investing in, selling up immediately isn’t necessarily the correct response. 

You should step back and weigh up your decision - don’t sell because of impatience, excitement or fear.

You should also consider whether a share price drop is likely to be short-term or in response to one-off bad news, to which a solution may already be in the works.

Tip: Don’t sell purely on impulse if a share price drops suddenly, short-term dips don’t always mean long-term decline.

What platform should I use to sell shares?

The cost of selling shares is dependent on which platform you use.

Although some online platforms won’t charge you, most brokerages will charge a commission for trading in your shares — either as a flat fee or a percentage.  

Before selling up, it’s important for you to look into what fees you’ll be charged through your brokerage.

This can influence whether you sell all of your shares in one go — to avoid multiple charges — or sell them off gradually, if there are no charges on your sales.

How long does it take to sell shares and receive funds? 

Once your sell order has been processed and completed, it usually takes two to three working days to receive your funds in your brokerage or investment platform account.  

You can usually then withdraw the cash or reinvest it if you prefer.

How to use order types to sell shares 

If you’re selling your shares, a priority should be to limit your losses, but this may be impacted by how keen you are to sell and at what price. 

For example, you could use a market order to sell at any price as soon as possible, even if it’s not your desired price. Share prices can change quickly, and even a slight delay in executing your order can mean you get a different price.

You have options if you’re more specific about the price point at which you’re selling. 

A limit order allows you to sell a share when it reaches a certain price or above that price, while a stop order is for when a share reaches a pre-set price or falls below it. 

Finally, a stop-limit order means that once the value falls to the stop value, the order then becomes a limit order.

Here's an example:

If the stop price is £50 and the limit price is £40, the limit order will be triggered once the value drops to £50.

The sale will then be executed as long as there is a buyer willing to pay £40 or more.

If you’re selling through a brokerage or investment platform, you may be able to specify how long your sell order is open. 

For example, your sell order may expire if your shares are not sold by the end of the day or until they are sold (with a time limit), or your order could be cancelled if shares are not immediately sold.

Are there any taxes I should look out for?

Alongside brokerage fees, selling your shares could result in tax charges, depending on how much money you make from the sale and the type of account you hold them in.

If your shares are held in a stocks and shares individual savings account (ISA), there will be no tax to pay. However, if they were in a general investment or trading account and you made a profit during your ownership, you may need to pay capital gains tax (CGT) on the sale.

However, everyone has a tax-free allowance for gains before CGT is charged, which is currently £3,000 a year (or £1,500 for most trusts).

CGT will be charged on gains in excess of the allowance at a rate of 18% if you still fall within the basic rate tax bracket or 24% if you are in the higher or additional tax band.

If you sell your shares because they have dropped in value, you won’t need to pay tax, as there has been no capital gain. It’s still a good idea to report these losses to HMRC, as you may be able to use them in the future by offsetting them against gains to reduce a CGT bill further down the line.  

Can I transfer my shares into an ISA without selling them? 

Yes, you can via a process known as Bed and ISA

This is when you sell investments held in a brokerage account and buy them back in an ISA. 

Bed and ISA allows you to protect your income and any future growth from capital gains and income tax. You can also use your annual ISA allowance of £20,000. 

You can usually do Bed and ISA via an online investment platform, which can take up to 10 working days.  

Before you start the process, it’s worth stressing that any profits from investments in your brokerage account may be subject to CGT.

To minimise tax, people often sell shares gradually each year and aim to keep their gains below the £3,000 threshold for CGT.
