Extent of Electrical Installation Covered by this Report.

That is not an EICR, it covers the whole installation (as far as possible), not one CU or perhaps one socket. In my view, this is invalid to allow rental.

I see nothing wrong with an EICR covering just part of a larger installation in principle - in just the same way that an EIC often covers just part of a larger installation (i.e. just the new work/alterations/additions done). In some situations it might be quite sensible to break the installation down into smaller portions - e.g. where shutting down the entire site at the same time would be unacceptably disruptive (factory, hospital, care home).

I'd agree that an EICR for a CU alone would be useless for showing that a private rented home meets electrical safety requirements - but in combination with other paperwork that covered the remainder of the installation, it could still be useful.

An EICR for a CU seems a little odd, but might be sensible in some circumstances - I suspect an previous EICR found problems with the old CU and it's been replaced. Normally a EIC for the CU change would be expected, but if one hadn't been produced for any reason or had been lost, then an EICR for just the ‘missing piece’ might be a reasonable regularization approach.
