Well in the agreement it does state that utilities are up to us, hence electricity and council tax were always paid on time. When I called Thames Water when we moved in they said the whole black is billed as one, not individual flats, so they could not send me a separate bill for my dwelling. Therefore, he was paying the bill out of the management costs. I assumed, therefore, our rent was covering his management costs. He says we should have let him know, but surely he should have contacted us if he wanted to arrange an alternative payment plan?
