What is Included in the 18th Edition Update Course?

What is Included in the 18th Edition Update Course?

The release of Amendment Two to the 18th Edition wiring regulations has brought an array of changes to the standards surrounding the practice of the inspection and testing of electrical installations, affecting electricians, electrical engineers, and those in allied trades.

We offer two 18th Edition Update courses at BES Group Electrical; one in person and lasting one day and one online which can be completed over a 12-month period. These courses are designed for those who have completed their 18th edition previously, as the latest information is tied with, and builds upon, the information covered during the 18th edition course. The key benefit of this is the avoidance of wasting time and money relearning information that you’re already competent in.

We’ve compiled the 7 modules you’ll learn during the duration of the course to help you prepare and achieve the pass mark.

The 7 key modules you’ll learn, all pertaining to the full outline of the regulations and how to implement the new rules in your practice, are as follows:

  • Scope, Object, and Fundamentals
  • Definitions
  • Assessment of General Characteristics
  • Protection for Safety
  • Selection and Erection of Equipment
  • Inspection and Testing
  • Special Installations or Locations

All will serve to create a full overview, preparing you with all the information you need for the final exam.

Changes to the 18th Edition Wiring Regulations

The following are some of the changes to the 18th edition wiring regulations that will be covered over the duration of the course. 

Chapter 41 – Protection Against Electric Shock

  • Metallic pipes entering the building will not need to be connected to the protective equipotential bonding if they have an insulating section at their point of entry.
  • RCDs for additional protection is now required for AC final circuits supplying luminaires (lights).

Chapter 42 – Protection Against Thermal Effects

  • Arc fault detection devices (AFDDs) are being recommended to be installed in AC final circuits in order to reduce the risk of fire.

Chapter 44 – Protection Against Voltage, Disturbances, and Electromagnetic Disturbances

  • The condition under which protection against transient overvoltage’s has changed. Instead, protection against transient overvoltage’s is now required when certain conditions are in place.

Chapter 52 – Selection and Erection of Wiring Systems

  • Cables now need to be supported throughout the installation process and now just in escape routes to prevent premature collapse in the event of a fire.


  • Appendix 6: The model forms have undergone some minor changes.
  • New Appendix 17: Energy efficiency recommendations.
