Given accommodation and invoiced to include rent regularly (8)
I believe the answer is:
billeted
'given accommodation' is the definition.
(billet can mean to accommodate soldiers somewhere)
'invoiced to include rent regularly' is the wordplay.
'invoiced' becomes 'billed' (I've seen this in another clue).
'to include' means one lot of letters goes inside another.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
The alternating letters of 'rent' are 'et'.
'billed' enclosing 'et' is 'BILLETED'.
'and' is the link.
(Another definition for billeted that I've seen is " found accommodation".)
