I have just moved over to Bulb and on the 23rd I took a electricity meter reading which I need to send to you. It was also the day that I was going away for 12 days and I left my one bedroom flat with everything including the fridge, internet turned off. The only thing left on was the smart meter from my previous supplier and when I returned 12 days later the meter showed 5 kWh of consumption in my absence. This is far too much for the powering of one smart meter.
Did you turn off your freezer?
