Dont bother trying to find it, it is totally out if date, hopelessly wrong and insignificant.
Yes there was a "push" by the NCC (or so they told the NCC Workshops) to get every van/motorhome over 3 years old to have an Electrical Installation Condition Report (it has changed from PIR inspection already).
However, the CC and C&CC stated that they would NOT be asking for certificates,and neither would the majority of sites( There were two sites which supposedly did ask).
In the last 3 years I have not carried out a single inspection, despite having been forced to spend a lot of money on so called "essential Courses", and neither have many NCC Workshops.
As it is at th emoment, NOTHING is changed , and I cannot see anything changing in the forseeable future.
