Our strata committee received a request to use a common property power socket to charge a battery for an electric bicycle… The occupier agreed to install an in-line meter for billing purposes and the strata committee was able to approve the minor works.
I bet the cost of installing the meter was more than cost of the electricity that an electric bicycle would consume in a very long time. For such a low level of consumption, I suggest it would have been more reasonable to calculate the likely consumption over a year (A generous calculation might be 10 cents per day x 365), round it up and request a payment that would be certain to more than cover the expense, say $50 for the year.
