Electricity supplier over-charging by including self-generated solar electricity in total consumption

How can I ensure my self-generated solar electricity that I consume (not export) is recorded separately from what is imported from the grid - I can understand paying my electricity supplier for what I import from the Gris, but surely not what my solar PV system self-generates - at present, I know everything (self generated electricity and import from the Grid) is included in one single reading on a smart meter (SMET2) register and my electricity supplier has been charging me for it - really frustrating as my electricity supplier has no incentive to get the problem resolved

​@BPLightlog, when I look at the readings on my Kaifa SMET2 smart meter, in the TOU Register, I can see that all the electricity consumption is shown against TO1 (and this is exact match for +A reading) - the remainder registers i.e. TO2, TO3, and TO4 are all showing 0.00 kWh - how can I resolve this?

If you only have a single rate tariff, it will all show as one ‘T’ reading. The way the system works, is for any solar generation to be used by your property (but not counted on your meter) and any additional need to be drawn from the grid. 
You should have a separate generation meter. 
Solar should not be shown on your Kaifa as a ‘T’ reading at all except for export

If you are being charged separately for both rates, that suggests that the smart meter is working correctly. 
Also as I mentioned earlier, unless the solar install was done wrongly, the smart meter cannot register it as used or to be charged. 
Did you find your generation meter ? If not you need to ask where it has been put

Thanks ​@BPLightlog, I’ll ask my solar PV installer where the generation meter lives assuming there is one - looking at the total consumption for which I’m charged by my electricity supplier, I’m convinced they are including self-generated electricity and power drawn from the Grid in the total consumption figure - the Kaifa smet2 meter is anything but smart - despite the install, I still have to provide manual readings to my electricity supplier!! - I’d happily go back to my old meter if I could and rip out the solar PV and battery install
