Komainu UK Limited: FCA regulated?

On the register, but not FCA authorised

This firm is registered with the FCA for anti-money-laundering checks only, which is how cryptoasset firms are registered. That is not authorisation: the FCA does not oversee how it treats customers, and FSCS protection does not apply.

Registered for 3 years
No FCA actions
Active company since 2019
Accounts filed up to 31 December 2025
On its latest accounts it owed £48.7m more than it owned

What does this mean?

Some businesses are required by law to have an anti-money-laundering supervisor. For this kind of business that supervisor is the FCA, and the registration is the only reason the firm appears on the FCA register.
What the FCA checks is narrow: that the firm identifies its customers, keeps records, and reports suspicious activity. It is the anti-crime paperwork behind a bank asking you for ID.
It does not check anything about you as a customer. Not whether the firm treats you fairly, not whether it is financially sound, not whether what it sells is any good. The FCA describes firms registered this way as “not authorised or subject to wider FCA regulation”.
So if the firm fails or treats you badly, there is no compensation to fall back on. The FCA's own position is that crypto is largely unregulated in the UK and that compensation for crypto losses is highly unlikely.

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.

Assets and liabilities

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.

Accounts filed at Companies House for company 11841450. Every figure is as filed, apart from total assets and total liabilities, which are added up from filed figures. Nothing is estimated.
