The overflow pipe outside my bathroom window drips at night but not during the day. Why is this and how can I stop it?It is nothing to do with the cistern as I have checked this. Please help as it is very annoying. Thank you AMW

is the overflow from a loft tank as you have stated its not from a toilet cistern?
if it is the cws tank in loft you have a faulty ball valve or you have cold mains passing to hot gravity either through a mixer tap or shower valve etc.
