Long story short, we need to add a conservatory and cloakroom to a property we rent out (changes to council rules). The total build will take 1mth and they get an extra toilet, new dining table/chairs, new patio and the added space. They have complained that the workman plugged into 1 socket (with their permission) to use a drill, and are asking who will pay the electric bill for this? How would we even work this amount out, because its not a month of constant drilling?
YABU- you should pay towards their bill
YANBU- they should suck it up
