If you are wondering how to buy shares in the UK, the process is more straightforward than most people expect. You open an account with a regulated stockbroker or investment platform, deposit money, choose the shares you want, and place an order, all of which can usually be done online in under half an hour. The harder part is making sensible decisions along the way: which account to use, which platform suits you, how much to invest, and how to keep costs and tax down. This guide walks through each stage in plain English, so you can get started with confidence rather than guesswork.
- You need a share dealing account, a Stocks and Shares ISA, or a self-invested personal pension (SIPP) to buy shares in the UK.
- Most UK investment platforms let you open an account and start trading within a day, often the same day.
- Fees vary widely between platforms, including account charges, dealing commissions and foreign exchange fees.
- A Stocks and Shares ISA lets you buy and sell shares without paying Capital Gains Tax or additional tax on dividends, up to your annual allowance.
- Only invest money you can afford to leave for several years, since share prices can fall as well as rise.
- Diversifying across companies and sectors reduces the risk of any single investment causing serious damage to your portfolio.
What buying shares actually means
When you buy a share, you are buying a small piece of ownership in a company. If the company does well and its value grows, your shares are typically worth more. If it struggles, they can be worth less, and in the worst case, worthless. Some companies also pay a portion of their profits to shareholders as dividends, usually a few times a year.
Shares are traded on stock exchanges, with the London Stock Exchange being the main venue for UK-listed companies. You do not buy shares directly from the exchange yourself. Instead, you go through a stockbroker or an online investment platform, which acts as the middleman that executes your order.
It is worth being clear-eyed from the start that share investing carries risk. Unlike money in a savings account, the value of shares can go down as well as up, and you could get back less than you put in. This is why shares are generally seen as a longer-term option, typically five years or more, rather than a place for money you might need at short notice.
Step 1: Decide which type of account you need
Before you can buy a single share, you need somewhere to hold it. In the UK there are three main options, and many people end up using a mix of them over time.
A general investment account (sometimes called a dealing account) is the simplest option. There is no limit on how much you can pay in, but any gains above your annual Capital Gains Tax allowance, and any dividend income above your dividend allowance, may be taxable.
A Stocks and Shares ISA is an Individual Savings Account that wraps your investments in a tax-efficient shelter. You can pay in up to your annual ISA allowance across all your ISAs combined, and any growth or dividends within the ISA are free from Capital Gains Tax and further income tax. For most beginners investing for the medium to long term, this is the natural starting point.
A Self-Invested Personal Pension (SIPP) lets you buy shares within a pension wrapper, benefiting from pension tax relief on contributions, though your money is generally locked away until you reach the minimum pension age. If you are thinking about how shares fit into your wider retirement planning, our complete guide to private pensions in the UK explains how SIPPs compare with other pension options.
Many beginners choose to build up an emergency fund and clear any expensive debt before investing at all. If you are not sure where shares fit into your broader financial plan, it is worth reading a guide on how to save money in the UK first, so your foundations are solid before you take on investment risk.
Step 2: Choose a platform or stockbroker
Once you know which type of account you want, the next step is choosing a provider. There are dozens of UK platforms, ranging from long-established stockbrokers to newer app-based services aimed at first-time investors.
Things worth comparing include the range of shares and markets on offer, whether the platform supports ISAs and SIPPs as well as general accounts, the fee structure, and how easy the app or website is to use. Some platforms charge a flat monthly or annual fee plus a small charge per trade. Others charge a percentage of the value of your holdings instead. Neither structure is automatically better, it depends on how much you plan to invest and how often you plan to trade.
It is also sensible to check that any platform you use is authorised and regulated by the Financial Conduct Authority (FCA), and that it participates in the Financial Services Compensation Scheme (FSCS), which offers protection if the firm itself fails.
| Factor | What to check |
|---|---|
| Regulation | Confirm FCA authorisation and FSCS protection before opening an account |
| Account types | Does it offer a general account, Stocks and Shares ISA and SIPP if you need one |
| Fees | Account fee, dealing charges, foreign exchange fees and any exit fees |
| Market access | UK-listed shares plus, if wanted, US and other international markets |
| Usability | Clear app or website, straightforward order process, useful research tools |
| Minimum investment | Some platforms allow small regular contributions, others expect larger lump sums |
Step 3: Open and fund your account
Opening an account typically involves providing your name, address, date of birth, National Insurance number and some form of identification, in line with anti-money laundering rules that apply across UK financial services. Most providers can verify your identity electronically, so approval is often instant or takes no more than a day or two.
Once your account is open, you fund it by transferring money from your bank account, usually by debit card or bank transfer. Some platforms also allow you to set up a regular monthly payment, which can be a useful way to invest smaller amounts consistently rather than trying to time a single large purchase.
If you run a limited company and are considering investing surplus business funds, this is a different situation from personal investing, with its own tax and regulatory considerations. It is worth first making sure your business banking is set up properly, and our guides on comparing business bank accounts in the UK and opening a business account in the United Kingdom cover the essentials before you look at company investments separately.
Step 4: Choose your shares
This is the step that tends to feel most daunting, but it does not need to be complicated. Many beginners start by researching a small number of well-known companies whose businesses they understand, looking at basic information such as what the company does, how it makes money, and how its share price has performed over time.
It is generally sensible to avoid putting all your money into a single company or sector. Spreading investments across different companies and industries, a principle known as diversification, reduces the impact if any one holding performs badly. Many beginners choose to hold a mix of individual shares alongside funds or investment trusts, which pool money across many companies in one purchase.
If you are not ready to pick individual companies, index funds and exchange-traded funds (ETFs) that track a broad market, such as the FTSE 100 or a global index, offer a simpler route to owning a diversified basket of shares in one go.
Step 5: Place your order
Once you have decided what to buy, placing an order is usually a matter of searching for the company or fund by name or ticker code, entering how much you want to invest or how many shares you want, and confirming the order. Most platforms show you the current price before you confirm, along with any dealing charge.
There are a couple of order types worth knowing. A market order buys at the best available price right now. A limit order lets you set a maximum price you are willing to pay, and the trade only goes through if the share price reaches that level. Beginners often use market orders for simplicity, since UK share prices for larger companies do not typically move dramatically in the short time it takes to place an order.
After the trade settles, usually within a couple of working days, the shares will appear in your account, and you can track their value alongside any dividends paid.
Understanding fees and tax
Costs can quietly erode returns over time, so it pays to understand them from the outset. Common charges include a platform or custody fee for holding your investments, a dealing commission each time you buy or sell, and a foreign exchange fee if you buy shares listed outside the UK. Some providers also charge for paper statements, account transfers, or inactivity.
On tax, shares held in a general investment account may be subject to Capital Gains Tax when you sell at a profit above your annual allowance, and dividend income above your dividend allowance may be taxed as income. Shares held within a Stocks and Shares ISA are shielded from both of these, within your annual ISA allowance. Tax rules can change, and your own circumstances will affect what you owe, so it is worth checking current HMRC guidance or speaking to a qualified adviser if your situation is complicated.
Common mistakes beginners make
A few patterns crop up repeatedly among new investors, and being aware of them can help you avoid unnecessary losses.
- Investing money that might be needed in the short term, then being forced to sell during a downturn.
- Putting too much into a single company, especially one that feels exciting rather than one that has been properly researched.
- Chasing recent strong performance without understanding why a share has risen, or whether that trend is likely to continue.
- Trading too frequently, which racks up dealing charges and can trigger unnecessary tax events.
- Ignoring fees, which seem small individually but can add up meaningfully over years of investing.
- Failing to diversify, leaving a portfolio exposed to the fortunes of just a handful of companies or one sector.
Frequently asked questions
How much money do I need to start buying shares in the UK?
There is no legal minimum, and many platforms allow you to start with a relatively small amount, sometimes as little as a few pounds through regular investment schemes. That said, dealing charges can make very small one-off purchases less cost-effective, so some investors prefer to build up a slightly larger sum before placing individual trades.
Do I need a financial adviser to buy shares?
No, you can open a share dealing account or Stocks and Shares ISA yourself and manage your own investments without an adviser. Many UK investors do exactly this, particularly for straightforward, long-term investing. However, if your finances are complex, or you want personalised advice on tax, pensions or overall strategy, a regulated financial adviser can provide guidance tailored to your circumstances.
Is it better to buy shares in an ISA or a general account?
For most UK residents, a Stocks and Shares ISA is the more tax-efficient starting point, since it shelters gains and dividends from tax within your annual allowance. A general investment account becomes more relevant once you have used up your ISA allowance for the year, or if you specifically need a type of investment that is not available within an ISA wrapper.
Buying shares in the UK is genuinely accessible once you understand the basic steps: choosing the right account, picking a suitable platform, funding it, researching what to buy, and placing your order. The details around fees, tax and diversification are where beginners most often go wrong, so taking a little extra time to get those right from the start will serve you well as your portfolio grows.
