I just received my quarterly gas and electricity bill and I am shocked. According to it, we have used more than double gas than the same period last year. Last year we've used 1785 kWh, this year 3719 kWh for the same period of 3 months (may - august). With this being quite a warm period and us not used any heating at all. I struggle to understand how we could use so much more. I've already called my provider (Scottish Power) and not a very nice person on the other end, basically told me that this is how much we've used and to pay up. The only 2 things that use gas at home is boiler (hot water + heating) and cooker. Therefore, I am considering installing one of the energy monitors to see what is using so much gas. One thing though is that both of my meters are outside of the property (next to the front entrance in separate boxes on the front wall) and therefore I have no power supply anywhere near. Is there anything I can do to see what uses so much power/gas?
