Where oh where do these figures come from? UK. I pay toda, domestic tariff, USD 0.42 per pKWh. Plus 5% Vat. That ignores the Standing Charge of USD 0. 56 per day connection charges, plus Vat at 5%.
The dataset they're supposedly using is:
https://www.globalpetrolprices.com/electricity_prices/
Which has UK: USD 0.413 for households, 0.338 for businesses.
Neither of which have any relationship with 0.27.
