Just using an EICR for their legislation was a "simple" solution that has caused lots of issues due to poor guidance, the scam artists and the way it was implemented.So if a £150 EICR failed on something like the gas bond had come off the clamp then the tester could charge £100 to reconnect as they know it would be cheaper than getting another EICR as that’s the only way they can get a satisfactory certificate without paying another electrician for another full test.
Everyone just wants page 1 to say satisfactory on an EICR the rest of it could be blank for all they care.
I did wonder whether a simple additional list for domestic rental properties created at the time of the original certificate might have some benefits - which lists exactly the remedial work necessary to be carried out (C2s and any C1s that weren't corrected immediately) - Then each item could be ticked/signed as it was done - as long as the entire list is completed, then landlord has complied.
Currently I've seen plenty of EICRs with C2s where it's not immediately obvious what the problem or the solution is, because of poor form filling.
Changing a pendant shouldn't really need the original inspector to come back and re test - and it should also be possible for the landlord to use someone competent in changing pendants (but not maybe in EICRs) to do so. Whereas a CU change obviously needs a higher level of competence, registration etc.
I generally have prior agreement to change fittings as I go if necessary, but obviously that's not always the case.
There would also be issues with that system no doubt, and the "bad" landlords would continue to employ people who pass things incorrectly - but at least it would be a recognised way for letting agents, tenants, and other non electrical people to know what work has to be done.
