Umm, as a soon to be ex-pat I can tell you the latest money making scams.
First home solar power is now out! You can't sell excess energy back to the grid, you have to give it for free. Anyone with solar is banned from having storage batteries. This is because the energy companies make nothing from you. In future only the energy companies can generate from solar.
Secondly the energy companies have petitioned the government on tariffs as well. energy price stays the same, standing charge for meters increases by 30% with vat charged on the top.
The reasoning is thus- electricity consumption is very low for 9 months of the year so the return on an increase in tariff is negligible, However increase the standing charge and as a company you are quids in. Even holiday homes that stand empty for months will pay a huge increase!
