In-Home Displays for 3-phase meters.

A friend continues to have issues with the metering of his 3-phase supply.

(His previous problem was on having the 3-phase supply installed that although they removed the previous 1-phase meter, they continued to bill for that meter a daily standing charge and an estimated consumption, together with an estimated consumption for the 3-phase supply.  It took intervention by the Energy Ombudsman to resolve the double billing.)

The 3-phase smart meter cannot communicate with Sottish Power.  However they will not come out to read it, nor explain how to read it.  It appears to me to be a dual rate meter although he is not on a dual rate rate supply.  Downloading Scottish Power's meter reading instructions does not give sufficient info to obtain a reading. 

As a possible part solution, does anyone know whether Scottish Power (MANWED region) supply In-Home Displays for their 3-phase meters?

Thanks.
