Periodic Inspection - Fixed Wire Testing


All electrical installations should be subject to periodic inspection and testing to prevent:

  • Damage through wear and tear
  • Corrosion
  • Excessive electrical loading
  • Ageing
  • Environmental influences

Legislation requires that certain electrical installations are maintained in a safe condition and therefore must be regularly tested.

Periodic inspection and electrical installation testing should be considered if:

  • It is a requirement implied by Licensing Authorities, Public Bodies, Insurance Companies, Mortgagors and Landlords.
  • Additionally, to assess compliance with the current IEE Wiring Regulations.
  • On a change of ownership or tenancy of the premises.
  • On a change of use of the premises.
  • After alterations to the original installation.
  • Because of any significant change in the electrical loading of the installation.
  • Where there is a reason to believe that damage may have been caused.

Industrial 3 years
Buildings open to the public 1 year
External 3 years
Caravan Parks 1 year
