increase in electricity bill

[vandriver]

Got bill the other day it has more than doubled. It was in fact the largest bill I have ever gotten. March bill was actual reading, May bill was an estimate, and July bill accurate. Thus the rise has taken place in last 4 months. Nothing different in use so cannot fathom the rise.

March was incredibly cold this year.Do you use electricity for anything like heating,hot water?

No gas for heating and sometimes hot water. Timer on immersion. I cannot see where an extra 100 would come from. Fish tank got with pump is the only change. Does anyone else know if this would cause such an increase?

It is entirely possible, if the pump is 500 watts running 24/7.
