- No FCA actions
- Active company since 2022

Responsible principal firm
G10 Capital Limited Reference number: 648953 View firm →What does this mean?
- An appointed representative (AR) can carry out regulated financial services, but is not directly authorised by the FCA. A principal firm holds the authorisation and is legally responsible for the AR's conduct.
- Leon Capital LLP (FRN 976148) is an AR of G10 Capital Limited (FRN 648953). When you use Leon Capital's services, the FCA authorisation sits with the principal firm.
- Example: if you take financial advice from Leon Capital, complaints and compensation usually follow the same rules as dealing with the principal, but this depends on the product and your circumstances.
- Before you proceed, confirm contact details match the official FCA register for both firms. Scammers sometimes clone legitimate AR names and FRNs but use fake phone numbers and websites.
Website, phone number and address
Compare these against whatever you were given. Scammers clone real firm names and reference numbers but use their own phone number and website, so a detail that does not match the register is the clearest warning sign there is.

Net assets
About these figures
- Turnover
- Money taken from sales in the year, before any costs.
- Profit before tax
- What was left after the year’s costs, before corporation tax. A minus figure is a loss.
- Net assets, or total equity
- Everything the company owns minus everything it owes. A minus figure means it owes more than it owns.
- Total assets and total liabilities
- Everything the company owns, and everything it owes, on the last day of the year. The gap between them is its net assets.
- Cash at bank
- Money in the company’s accounts on the last day of the year.
- Owed within a year, owed after a year
- Debts and bills due in the next twelve months, and those due later.
There is no turnover or profit: small companies do not have to publish them.
