Values carpets (5)
I believe the answer is:
This clue might be a double definition.
'values' is the first definition.
(rating is a kind of valuing)
'carpets' is the second definition.
The definition and answer can be both to do with contact as well as being verbs in their -s form.
Maybe you can see an association between them that I can't see?
Can you help me to learn more?
(Other definitions for rates that I've seen before include "Former local taxation system", "Speeds, evaluates", "Fixed prices", "Local taxes on commercial property", "Tax paid by businesses to a local authority".)
