In service daily (4,4)
I believe the answer is:
home help
'daily' is the definition.
(daily can mean a cleaner who visits daily)
'in service' is the wordplay.
'in' becomes 'home' ('he's in' can mean 'he's home').
'service' becomes 'help' (synonyms).
'home'+'help'='HOME HELP'
(Other definitions for home help that I've seen before include "Carer" , "Domestic assistant" , "Social worker" , "hand?" , "cleaner" .)
