IT fraud alert

We have been made aware that some of our corporate customers have received an email that appears to have been sent from Thirteen.

25 Sep 2017

The wording of the email varies, however it claims that there is an outstanding invoice and immediate payment is required. There is an instruction to click on a web link, and a telephone number with a Dartford area code is provided as a contact method.

This is a scam.

Thirteen sends its invoices in the post unless an ad-hoc request has been made to send it by email. We would never provide a link to a web portal to view an invoice or make payment. A telephone number for Thirteen will usually be a Middlesbrough area code (01642) or our main Customer Services number: 0300 111 1000.

We are asking our corporate customers to remain vigilant and make their employees aware of this issue. If anyone receives such an email, please forward it to
