Flushed toilet downstairs.
Came up and still heard "tank"emptying sounds ?

Yes, in that I can hear a certain amount of water moving through pipes and the cold weather tank re-filling in the loft (the toilet cistern having been refilled from the cold water tank). Not noticeable unless it’s dead of night quiet though.
