Special Fault Investigation 2 (SFI2)


If any of your customers have a problem with their broadband service and the copper path appears to be working, our engineers will investigate further and hopefully go on to pinpoint and correct the issue. A Special Fault Investigation 2 (SFI2) will help to speed-up fix times for broadband-related issues and tell you more about what we do on your behalf.

Key benefits:

  • You're in control. You tell us where to test, what to test and what tests to do
  • Next generation testers make the process more objective and consistent
  • You only pay for what we do, making pricing fairer
  • Save time by authorising tests in advance
