Due diligence

Before appointing a new supplier, or authorising most payments, we must take reasonable steps to ensure that they are financially and professionally sound.

Organisational status

To comply with HMRC and other requirements, we will need to see evidence on a letterhead of your bank account details (including payee where a sole trader is trading under another name), company, charity or equivalent registration, VAT registration and/or Unique Taxpayer Reference as applicable.

We might also ask about recent trading history and may take up references. Financial track record may be checked through our licensed credit reference agency.

Declaration of a possible conflict of interest or previously-terminated contract does not in itself stop a supplier working for us.


This depends on what you could be supplying to us, along with the size and constitution of your organisation. It might include some of the following:

  • Professional certification or qualifications, operational and trades certificates, relevant memberships
  • Insurances with cover to an appropriate level, such as:
    • Employer’s Liability
    • Public Liability
    • Professional Indemnity
  • Membership of a recognised Safety Scheme in Procurement (SSiP) scheme
  • Health & safety status
  • ICO certificate
  • Enhanced DBS clearances
  • Policies or statements confirming adherence to legislation and policies covering area such as probity, anti-bribery, equality & diversity, modern slavery and data protection
  • Awareness of Safeguarding and how to report any concerns.


You may be invited to submit your company’s policies for some activities. If your company does not have such policies, we ask that you agree to follow Radian’s own which you can view on our Policies page.
