If however you wish to produce two separate EICs or EICRs, or record Ze for both installations on the one EIC or EICR, that’s totally up to you.
I refer you again to the last sentence of 542.1.3.3.2 installations may have a common supply as it where say at the cut out however one installation feeding as you say another is just one installation as in a supply feeding a external building fed from one consumer unit whether you TT the other end or not.
2 Consumer units fed from one cut out such as a split load DB and say a 2 way shower DB , tails in Henley blocks maybe considered 2 installations by some.
Some consider one supply equals one electrical installation regardless.
