How to buy shares in the UK
The accounts, the costs and the steps, explained simply.
The short answer
To buy shares in the UK you open an account with an FCA-authorised investment platform, add money, then place an order for the shares or funds you want. The main choice is the type of account, because an ISA protects your gains and dividends from tax, while a general account does not. Platforms differ mainly in their fees, so it is worth comparing them before you start.
Step by step
- Choose the account type. A stocks and shares ISA (up to £20,000 a year across all your ISAs for 2026/27), a general investment account, or a pension. See ISAs explained and pension or ISA?
- Pick a platform. Check that it appears on the Financial Conduct Authority register, then compare the fees.
- Fund the account. Most platforms accept a bank transfer or debit card.
- Choose what to buy. Shares in single companies, or funds that hold many investments in one purchase.
- Place the order. A market order buys at the current price. A limit order only buys at a price you set or better.
What it costs
- Platform fee: usually a percentage of what you hold or a flat monthly amount. On a small pot a flat fee can take a bigger share.
- Dealing fee: a charge each time you buy or sell, which some platforms waive for funds.
- Fund charges: funds charge a yearly percentage that comes out of the fund itself.
- Currency fees: buying overseas shares often involves an exchange charge.
- Stamp Duty: you usually pay 0.5% on electronic purchases of shares in UK companies. You do not pay it on new share issues or on buying from fund managers (unit trusts and OEICs).
Things worth knowing before you start
- Single shares can fall a long way. Many people hold funds that spread the risk across lots of companies.
- Only invest money you will not need soon. Prices can stay down for years.
- Be wary of anyone who contacts you out of the blue promising returns. Check any firm on the FCA register and its warning list.
- Keep a record of your purchases, because you may need them for Capital Gains Tax. See tax on shares explained.
