For compliance and safety, it is essential that highly qualified personnel carry out electrical work and that it is regularly tested. You may need to inspect and test to comply with the IEE Wiring Regulations 18th Edition. Or if you have recently acquired ownership or tenancy of business workplace premises you may wish to ensure the installation is safe. If you suspect there is a fault or risk of failure, you must take steps to inspect the affected circuits urgently. IEE recommends the maximum time between periodic inspections:
  • Commercial premises – max 5 years
