A Leased Line is supported with a 7 hour fix SLA. This time does not apply if the fault is outside the reasonable control of BT Openreach, ie a road contractor digs through a fibre.
With Broadband, or Fibre Broadband, there is no specified fix time for the service, so it is fixed on a “best efforts” basis. The telephone line is also required for broadband to function, and this is supported with a fix SLA from BT Openreach. This will depend on the Care Level purchased with the line, but we always recommend the top service “Care Level 4” which is 24/7/365 4 hour fix. Again, there are exceptions for matters beyond the reasonable control of BT Openreach.
