Can’t Find the Mains Water Valve…

Hi, I’ve just bought BISF house that needs some work.
Started the renovation and it may be funny but I cannot locate the mains water valve to start doing work on bathroom plumbing.
Any suggestions where it could be?
Thank you,
Roman
Thanks Ed for your response. I followed your advice and have found under the kitchen sink right on the floor level.

Hi and welcome Roman, mine is hidden quite well so I guess it might be in the same place as yours! It’s under the kitchen sink, near floor level and half hidden in the boxed-in bit around the soil pipe. It’s on the window side of the soil pipe. I don’t know if they are always in the same place.
