Our electricity direct debit is over £500 per month - this is in part paying back arrears that accumulated when our direct debit was lower - but it has crept up steadily from £150 a few years ago to where it is now - for a while it seemed that every month we got a letter saying that our direct debit was being increased.
To give a bit of context: we are in a detached 3 bed cottage, with no mains gas / oil fired central heating, so I would expect our usage to be significantly higher than average - just not this high. We have solar panels for hot water, so we are not using the water heater a great deal (maybe 4 hours a week in the winter months). We have wall mounted electric radiators in main living areas (convection heaters in bedrooms, but don't use these much). We also have multifuel stoves in living and dining room without which the house is freezing (lately we have cut back on coal / wood as we were paying another £100 per month for this, and using the heaters more, and they really do not warm the house adequately, so it is not as if we are paying through the nose to superheat our home).
This does sound ridiculous, right? I can't believe that we are really using so much, but part of me is wondering whether this is just what it costs when you live in a poorly insulated stone cottage.
We are having our meter checked in a few weeks, so I am hoping that they will find that it is faulty and they owe us a massive refund - but I am not really expecting this outcome. Does anyone have experience of particular faults etc causing excessive usage? Can electricity 'leak' from a building? and how could we go about getting this diagnosed and dealt with?
We're desperate to get this under control - any advice would be massively appreciated.
