Electricity meter INCLUDES the electricity generated from my solar panels

Hi @JohnnyMack I can see how that would be wildly frustrating.

How  long have you had your PV system, and was it in an effort to solve your problem that you had the SMETS2 meter fitted?

Do you have your own generation meter, which records all that your PV panels generate (regardless of how much is used by you and how much is exported back to the grid).

Was the system installed by an MCS registered person…if so, they should not have left you in this position. 

I can well understand how frustrated you must feel at being actually penalised for producing your own power, but this doesn’t sound an intractable problem, given sufficient goodwill on the part of your energy supplier when you explain things to them! For example, your smart meter will be well able to separate imported electricity from exported electricity: you could carefully examine the function buttons on your smart meter and try and find the different registers for imported kWh and for exported kWh, that would be a good start in getting your supplier’s agreement that something is seriously up with their billing. 
 

I’m not an expert either, but it does sound to me as though it’s a metering problem: the DNO meter (which your energy supplier has to use) is not informing your supplier about what is being imported and what is being exported…but even that is not answering your main problem about why your total household consumption is being seen as totally imported from the Grid. 
 

Hopefully someone more knowledgeable will step in and help you further, but in the meantime do have a good examine of your smart meter’s readouts….
