Buy & sell shares with £0 commission

Share investing, also known as share trading, stock trading or share dealing, is the buying and selling of a portion of ownership in a publicly-listed company. If a company's share price rises, your investment can increase in value, and if it falls, your investment can go down.

We apply an additional FX fee spread to the current conversion rate at the time of execution. Here’s an example of how we calculate the CMC Invest FX fee for a conversion from GBP to USD:

We take the current exchange rate of 1.321 and multiply it by 0.005 (0.5%) to get our CMC Invest fee rate = 0.00660. We always round this number to 5 decimal points.

This rate is then applied to the money you want to convert to get the actual fee amount taken by us.

£100 (GBP) x 0.0066 = $0.66 (USD)

So, you'll get $132.10 (USD) from the simple FX conversion, minus our fee of $0.66 (USD), which is $131.44 (USD).

Yes, CMC Markets Investments Limited (registration number 948126) is fully authorised and regulated by the Financial Conduct Authority (FCA) in the UK. Retail client money is held in segregated client bank accounts, and money held on behalf of clients is distributed across a range of major banks, which are regularly assessed against our risk criteria.

Yes, your eligible deposits with CMC Markets are protected up to a total of £120,000 by the Financial Services Compensations Scheme (FSCS), the UK's deposit guarantee scheme. If CMC Invest ever went into liquidation, retail clients would have their share of segregated money returned, minus the administrator's costs in handling and distributing these funds. Any shortfall of funds up to £120,000 may be compensated under the FSCS.

Under the FCA's client money rules, we're required to segregate client money from our own funds (unless you agree with us otherwise). The money held in segregated bank accounts does not belong to us and will be held in a way that enables it to be identified as client money. Learn more about client money regulations.

In the UK, you won’t need to pay capital gain tax (CGT) on any profits you make from selling investments, and dividend tax on income you receive from companies in your stocks & shares ISA and self-invested personal pension (SIPP). Any profits and dividend income to your general investment account is taxable and will be shown in your ‘Consolidated Tax Certificate’, provided to you following the end of each tax year. Tax treatment depends on your individual circumstances and may be subject to change in the future.
