Fixed Installation Testing

Periodic Fixed Installation Testing (or Fixed Wire Testing) involves testing the electrical circuits and systems that distribute electricity around a building. It covers all the hard wiring in a building, whether that building is commercial, industrial or residential.  All electrical circuits in a building that are fixed, such as lighting, socket outlets, supplies to air conditioning and other fixed plant need to be tested.  You can find guidance for this testing and inspection process within BS7671 (The IEE Wiring Regulations).

Test frequency on new builds will be set by the designer responsible for the fixed wire installation. Thereafter it is specified by the test engineer in line with the following guidelines:

Maximum period 5 years between inspections and testing

  • Commercial (or change of occupancy)
  • Offices
  • Shops
  • Hospitals
  • Educational establishments
  • Restaurants and hotels
  • Public Houses

Maximum period 3 years between inspections and testing:

  • Industrial

Note that for some special installations (eg swimming pools, petrol stations, caravan parks) the recommended maximum period between inspections and testing is one year. Other regulations may apply such as Local Authority conditions/cinematograph (safety) regulations, etc.Contact Us
