Services having no sweets (7)
I believe the answer is:
offices
'services' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe there's a link between them I don't understand?
'no sweets' is the wordplay.
'no' becomes 'off' (I can't justify this - if you can you should give a lot more credence to this answer).
'sweets' becomes 'ices' (ice is a kind of sweet).
'off'+'ices'='OFFICES'
'having' is the link.
Can you help me to learn more?
(Other definitions for offices that I've seen before include "Bureaux" , "posts" , "Places of business" , "Government departments - where they sell tickets" , "business premises" .)
