I believe the answer is:
tenant
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">occupier</span>' is the definition.<br/ ><span class="explanation-format__explanation">(tenant is a kind of occupier)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tenant that I've seen before include "Occupier but not owner" , "Lodger" , "Rent payer" , "Occupier of rented property" , "individual bound by lease" .)
