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.

Past FCA permissions and consumer protection
- The record is closedCover you already have generally survives the cancellation: FSCS exists for firms that have failed, and the Financial Ombudsman Service can look at a complaint about a firm that has stopped trading, as long as the business was done while it was authorised. New business with this firm has no cover at all, because it is no longer permitted to carry it out.
FCA disciplinary action and complaints
No FCA disciplinary action. The Financial Ombudsman Service only publishes complaint figures for firms with 30 or more new complaints in six months, so there are none here for this firm.

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.
