Still begs the question why verify the voltage drop on a fifty year old socket circuit with aluminium conductors?
The next question will be “what was the permitted voltage drop at the time it was installed”? I presume the original circuit was designed to allow the connection of two 3 kilowatt loads at two separate sockets with there possibly being no more than half a dozen single sockets on the circuit. So the circuit may have been extended in an inappropriate manner, a bit of investigation will reveal if that’s so with additional sockets wired copper cables.
Note it on the EICR and crack on with something else or consider running a new circuit for additional sockets if that is what is required.
