Postcodes almost never.  The only time you would normally find them is 
where the building is a company's registered office.

Housenumbers seem to be only on (gut feeling) about 30% of houses these 
days, and maybe 5% of commercial premises.  (When they are on houses, 
they are typically unreadable after dark.  Almost no-one has front gates 
any longer, which might have carried them in the past.)

What appears on street signs and post boxes is the outbound postcode (up 
to the end of the first number).

Businesses are required to provide an address for service in 
advertising, including web sites.  This may well be their accountant's. 
Electronically, they need to provide a geographic address, but, on 
paper, I think a PO Box number is acceptable.  Non-compliance is 
endemic, e.g. businesses only contactable over mobile phone numbers.
