Hopefully someone can provide some advice here, I am unsure if there is any solution apart from just paying the bill in full.
Background is a friend and I started renting a "unit" (large house that has been split into two halves and each one rented separately) a bit over 6 months ago. There is only one water meter so bills are split between the two units, although when we moved in the other unit was vacant.
Our initial water usage bill was approx $50 (3 month period), paid entirely by us as other unit was vacant. Tenants moved into the other unit after this first period and our new water usage bill is approx $130 AFTER splitting (which means actual water usage cost increased from $50 to ~$260 since the tenants moved in next door assuming rental agency is actually splitting it 50/50). Although the additional $80 we would be paying is not really that much money I don't really think its fair for us to be paying for the other tenants' water usage when they use such a considerable amount more than us. They have a washing machine (my friend and I both wash clothes elsewhere) and also blast shit with the hose fairly often (no idea what they are doing out there).
Is there anything I can do about this? The rental agency is not particularly helpful at all and is slow to reply to any emails. They previously did not believe me that there was only one water meter and I had to take a photo to show them.
Sidenote: I/we would be open to moving out of here earlier if we could get out of the 1 year lease somehow.
Pro tip: Emails suck. Emails are easy to ignore.
Get on the phone and speak to a human at the rental agency. You are far more likely to get a better outcome.
Do the dwellings have the same address or separate addresses? Is it a strata title?
I'd personally be requesting a second meter be installed.
