Shouldn't think so bite the bullet and do an EICR, you said you did the testing should be quite simple, if you know what you are doing.
Seems to have been a misunderstanding of what I was trying to say, yes of course you are all right that an EIC is required for aboard change, i don't dipute that common knowledge really.
The OP was asked to change the CU, I mentioned that it is advisable to do an EICR prior to the CU SWAP, nit a regulation as rightly answered.
What I was trying to say unsuccessfully as it turned out was that the OP on completing the EIC has done testing of the installation (which us required) and issued an EIC, would it be that difficult to return and issue an EICR? the questioin I neglected to ask was why the CU swap was asked for in the first place, had there been an EICR done prior to the swap. was there any miscommunication between the OP and the letting agent.
Not making excuses for my earlier response, just trying to put my point over a little better, to all those who gave a disagree, I respect your points hope this explains my point a bit clearer.
As the OP was initially asked to swap the CU he has correctly issued an EIC for the board change.
You may ask why the letting agent neglected to order an EICR in the first instance? left hand not knowing what the right hand is doing, why was the board change ordered. a knee jerk reaction on their part? go figure.
