Seeing improvements now after many a balance been carried out. Seeing around 150 miles on the "guess oh meter" on normal and about 162 on eco. Thank you to all those who chipped in for advice, I t is very much appreciated

What you can do as a bit of a short cut ( if you want to continue the balance cycle plan for a while ) is after a full charge & balance, is to take the car for a very short drive, of a few miles.
Then put the car back on charge again.
The SOC has now dropped to 95% then great !.
Put it back back on charge again.
It will soon hit 100% SOC and will jump straight back into another balance cycle once again.
Each time you check results, after the balance cycle has completed, don’t forget to use the same parameters to check your results.
Both trips reset, all 12 volt items turned off etc etc.

checked what I believe is BCM build number (picture attached),

That's ONE ECU. There are about 22.

The unofficial Thai app allows you to see all of them, if you have an Android phone and a decent OBD2 dongle.
See Project OBD2 - Mobile App v1.2.1 and later .

After many attempts to get hold of MG richmond Portsmouth. They eventually agreed to have the car in next week to update the BMS as car keeps asking to slow charge. So when I have been carrying out a balance it is not actually doing it even though the light indicates it is
