Just got the first electricity bill, looks like everything is working as it should 🙂
Rate             Consumption     Cost
7.14p/kWh   103.9 kWh       £7.421
28.17p/kWh 57.4 kWh         £16.179
That’s over 11 days, prices are +Vat of course 🙂
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
