TNBN Fault Report Centre

Please report your fault to us online using the form below.
Please note: If you are experiencing a line fault and are on Openreach Standard Service Levels 1 or 2, your fault will be investigated within the next 24 hours, excluding Sunday’s, Public & Bank Holidays. Should your lines be on Service Levels 3 or 4 please refer to our notes below for faster response lead times.

Please note: If you have a service effecting issue with your phone lines or broadband, and ONLY in the event that an Openreach or Talk Talk engineer comes to your site, as they cannot see a fault when at the local exchange, you could be charged a time related visit charge (£135 + vat) if the fault is proven to be with your own equipment or wiring and not with the network.
