Hounslow council has not yet moved to digital parking permits and, as I understand it, residents should display a permit in their cars. If you haven't had your permit, please contact one of your ward councillors who can do two things: ensure you are not fined for failing to display a permit while waiting for it; and ask for the permit to be reissued if it has been posted but hasn't reached you.
