Hi all - I have just purchased a ground floor maisonette which has a garden split into two, shared with the maisonette above. The previous owner was good friends with the owners above and so they never fenced around each others. There is one outside tap on my part of the garden, connected to my water supply. Historically, the owners above have been using this tap to water their garden. I have just been informed that we’re going on a water metre AIBU to suggest that they stop using as I can’t afford and don’t want to be (!) paying for their usage! Thank you for your thoughts
