Our notes

Strengths
  • Every company we checked holds a licence from a strict or standard regulator, from the FCA to the DFSA
  • UK client money is held in segregated accounts under the FCA's client money rules, with FSCS cover for eligible claims
  • No minimum deposit on the UK site and no charge from CMC for deposits or withdrawals
  • Licensed in the US, Canada, UK, Ireland, Australia and Singapore, all strict regulators
  • Spot forex priced at the quoted interbank spread plus a published commission (0.20 basis points of trade value at the first tier)
  • No account minimum and no inactivity fee
Watch out for
  • Inactivity fee of £10 a month after a year without trading
  • The UK site quotes minimum spreads (from 0.5 pips, or 0.0 pips plus commission on FX Active), not typical spreads, so check live prices before you compare
  • The FCA has warned about clone firms using CMC Markets' details, including ibplatform.info, ib-platform.info, ibplatform.co and marketstradeltd.com
  • Spot forex commission has a minimum of USD 2.00 per order, so very small trades cost more in percentage terms.
  • UK accounts are cleared and carried by Interactive Brokers LLC in the US for most products; IBKR says products are only covered by the UK FSCS in limited circumstances.
  • Margin accounts can go negative; IBKR's own disclosures say losses may exceed your original investment
  • IBKR also names companies in Hong Kong, Japan and India; we did not confirm those licences on 2026-10-20 and this profile does not cover them.

Risk warnings

The buttons to a broker’s website above the table are partner links: we may earn a commission if you open an account through them. That never changes the facts shown here. Trading leveraged products such as forex and CFDs carries a high risk of losing money rapidly, and most retail accounts lose money. Each broker’s own warning:

  • CMC Markets: Spread bets and CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 69% of retail investor accounts lose money when spread betting and/or trading CFDs with this provider. You should consider whether you understand how spread bets, CFDs, OTC options or any of our other products work and whether you can afford to take the high risk of losing your money.
  • Interactive Brokers: CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. 58.9% of retail investor accounts lose money when trading CFDs with IBKR. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.

Other head-to-head pages

Cost per lot is the typical EUR/USD spread in busy hours × $10, plus any round-turn commission, for one standard lot. “Not yet checked” means we have not confirmed that fact yet. This page compares facts; it does not rank the brokers or recommend either. Confirm costs and licences on each broker’s site and the regulator’s public register before opening an account: see how we review brokers and check a broker yourself.
