Utility workflow

Stay on the official compliance path

The utility page remains canonical. This tester surface should only help the user take the next step after the exact reporting and deadline path is clear.

  1. Use the SAWS program page to confirm whether the assembly is part of the annual testing program.
  2. Check compliance or find a registered testing company through the BSI customer portal.
  3. Complete testing and make sure the tester submits results through the correct BSI channel.
  4. For new service or construction, complete the CSI and Development Services steps alongside assembly requirements.
