TNBN Policy on identity when visiting a customer premises
  • Policy on proof of identity

All TNBN engineers undergo pre-employment vetting, and are issued with a photo ID card, which MUST be presented when entering your site. All TNBN Subcontractor engineers can provide their own ID at your discretion as proof of Identity.

On the rear of the card there is a number and explanation on how to confirm that the engineer is on official TNBN business. If the engineer does not present a valid identity card, is not the person on the card or there is any doubt, you can refuse access and call TNBN on 0800 019 5562.

Engineers are not required to present proof of identity such as passports or driving licenses as the TNBN identity card provides an equivalent and more readily verified proof of identity. Engineers are instructed that they should ONLY hand over their identity card in exceptional circumstances and then on receipt of a site pass card or token. In these circumstances they MUST be confident that their card is securely stored by a security guard or similar and may ask for a signed receipt for the card.
