TRADEHELP LTD Reference number: 697812 View firm →What does this mean?
- An introducer appointed representative can only pass your details to its principal firm. It cannot recommend products, give financial advice, or arrange deals on its own.
- MOS HEATING LTD (FRN 1063167) introduces customers to TRADEHELP LTD (FRN 697812). Any regulated advice or arranging is done by the principal, not MOS HEATING.
- Example: if MOS HEATING refers you to a financial adviser, the advice should come from the principal firm, not from MOS HEATING itself.
- 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.

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 15039399. Every figure is as filed, apart from total assets and total liabilities, which are added up from filed figures. Nothing is estimated.
