You don't get "classed as an energy company", you just have to pay taxes on the money you make from selling the energy. This starts at 30 kWp (up to that size, the income is tax free), which is very likely more than what you could put on a private home.

well I mean okay, but it happened to me, and i had to pay a lot to an accountant to do this paperwork and i resent it utterly. I guess it’s unpopular here to be dissatisfied with the insane bullshit tax system in this country.

I didn’t make a profit, it’s not commercial — but apparently getting to almost break even on my energy bills is a “profit”.
