How can I find out if an online company is genuine? I have checked Company House and was unsuccessful - is there some other way to find out if a business is sound or a con?
Ask their local trading standards office if they have a file on the company or have been "made aware" of their activities, or ask their local chamber of commerce. Alternatively you could Google the company's name and see if anyone has posted any comments about them.
It would only be on Companies House if it was a registered limited company, limited liability partnership, plc etc... in England or Wales.
It would be a company registered in Ireland or otherwise abroad for tax reasons. Ireland has its own company database and some others but it's much harder to track if registered abroad.
It would just be a trading name.
If you let us know the name of the company then someone may have more luck finding some more info for you.
A limited company is required to have its registered name, number and address on the website (although not necessarily on every page), so even if it uses a trading name, it should have the registered name somewhere.
The Companies House website, by the way, also details Scottish companies, and has very basic details of those registered in Northern Ireland too.
As commented, it may not be a limited company, or indeed a UK company, at all.
