A letter arrives at your home - addressed to a company you've never heard of. Would you know what to do?

Criminals are registering companies at innocent people's addresses at a shocking scale - sometimes covering an entire street at a time. In this episode, Shari Vahl, Dr Elisabeth Carter and former fraudster Alex Wood find out the alarming consequences if your home is targeted - and how to fight back.

Fake companies expert Graham Barrow joins the programme to explain what the criminals are after, and to discuss whether Companies House's latest crackdown is working.
