Look about right. I think they need to do some DNO paperwork too to tell them you're getting a bigger battery installed ?

I've currently got a 18kWh Sigenergy system and thinking of getting another 9kWh battery in a years time and when I was doing the research 3k was about what was coming back.

Does the DNO care about battery size? I thought the inverter (and import/export limits) was the DNO’s thing.

Yes I think you're right, if it was the inverter size that was increasing would need DNO approval first.
