The 18th edition of the IET wiring regulations is live and
is an essential qualification for anyone working in the electrical industry.
The 18th Edition, issued on 2nd July 2018, is the very
latest update to the wiring regulations, and the design of all new electrical
installations will be required to comply with the 18th Edition from January
The publication includes subtle changes to current
regulations, some new regulations and the removal of some existing regulations.
The introduction of new devices – arc fault detection
devices (AFDD) – can provide an additional level of electrical safety from
faults and are expected to be widely adopted across the industry.
Existing installations that were installed in compliance
with earlier editions of regulations will not be effected, and this does not
mean that they are unsafe for continued use or require upgrading.
