To verify who you are, where you live and that you’re not bankrupt 
Identity – in today’s connected world, they need to double check who you say you are; this is also for your own security (to stop someone else taking out a loan in your name!).
Address – as part of your ID checks, they also need to check you have a permanent address.
Solvency – our lenders currently only accept borrowers who are solvent, in other words if you’re bankrupt, in an IVA or Trust Deed, or debt management plan, you’ll not be accepted, so they need to check this.
