My reading of Matt's message is that he is trying to link *instances* of 
my:Thing to instances in the Companies House RDF, viz:

    my:object a my:Thing .
    my:object predicate <http://business.data.gov.uk/id/company/08209948> .

Matt:  amongst the predicates you might use is:

   my:object owl:sameAs <http://business.data.gov.uk/id/company/08209948> .

This is a very strong statement in that it says the your object is 
identical to the thing identified by the Companies House URL.  Every 
property of my:object is also a property of the companies house resource 
and vice versa.  There is the possibility that there could be subtle 
modelling differences between your object and the Companies House one.  
If that is the case, don't use owl:sameAs.

An alternative is:

   my:object rdfs:seeAlso 
<http://business.data.gov.uk/id/company/08209948> .

This is a much, much weaker statement.  rdfs:seeAlso provides a link but 
with no formal meaning.  Its definition says:

[[
that is used to indicate a resource that might provide additional 
information about the subject resource.
]]

So if you want to make an assertion when you make the link, rdfs:seeAlso 
doesn't cut it.

Neither of these is UK specific.

Others on the list may provide further suggestions with more suitable 
meaning.  A good thing to think about would be "what am I trying to say 
when I assert this link".

owl:sameAs says roughly - "these URIs identify exactly the same thing".

rdfs:seeAlso says roughly - "retrieving this link might get you more data"
