If it is of any help and makes the situation a bit clearer, here is a copy of the information I have to hand relating to the inspection and test being introduced.
Mutual electrical safety in the UK
Summary
It is a matter of civil law that both parties, the caravan/motorhome owner and the touring park owner, be able to reassure the other as to the satisfactory condition of the mains electrical installations.
The relevant standard is BS 7671:2008 "Requirements for Electrical Installations" (commonly known as the 17th Edition IEE Wiring Regulations), and the paperwork to be offered should be the most recent Periodic Inspection Report ("PIR") or the manufacturer's/installer's original certificate in the case of brand new caravans or motorhomes.
Failure by either party to satisfy the other can be sufficient reason to nullify any contract and be grounds for prosecution in the event of any injury and/or loss.
The supply by a dealer, workshop or mobile engineer of any such PIR is a chargeable addition to the work they undertake. Before inspection, please ensure the customer is aware of this charge and the reasons for the report - touring parks
are legally allowed to refuse connection to the public network where a caravan or motorhome does not hold a valid PIR. The customer may refuse a PIR but a formal refusal, signed by the customer, should always be issued.
Details
The relevant Statutory Instrument is "The Electricity Safety, Quality and Continuity Regulations 2002", as amended.
A PIR, like a vehicle MoT, is valid for one year, provided that nothing changes that substantially affects the condition of the system which was reported on.

Any engineer who is working on or checking the electrical system of a caravan or motorhome is liable to provide a new PIR irrespective of how recently the previous one was dated or whether any work is done on the system.
Any small works done on a system should be accompanied by a Minor Works Certificate. More extensive work should be covered by an Electrical Installation Certificate.
Any report or certificate can be accompanied by Observations and Recommendations made by the competent person, using the code:
Code
Meaning
1
Requires urgent attention
2
Requires improvement investigation
3
Requires further investigation
4
Does not comply with BS 7671:2008, amended to . This does not imply that the electrical installation inspected is unsafe
Two examples of Code 4 are: old wiring that doesn't have the modern colour coding, especially on the earthing or bonding cables (say green and not green/yellow); and a bonding connection that doesn't have the correct bond label.
An example of Code 2 could be: where 12 V and 230 V cables are running together in a bed box in which it is known that the caravan or motorhome owner stores objects (such as spades) that might damage them, there is the possibility of voltage migration.
