How to link to Companies House (UK) data?

As a relative newcomer to LOD (first post here), I have a very basic 
question: How to link from an object specified in RDF to a Companies 
House URI for data about a particular registered company?

Suppose, for example that I have a class, my:Thing, and that some of 
these Things are also registered companies. I want to provide a link 
from an instance of my:Thing to the data held by Companies House.
Let's suppose that the Companies House URI is 
http://business.data.gov.uk/id/company/08209948.

Is there an existing predicate that I can simply add to my resource 
description? Like this:

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

Or do I need to modify the definition of the my:Thing class in order to 
provide this link? If so how?

An extra requirement is that I don't want the mechanism to be 
UK-specific. I see from the Companies House data model 
(http://business.data.gov.uk/companies/docs/data-model-reference.html) 
that it uses the Registered Organization Vocabulary 
(https://www.w3.org/TR/vocab-regorg/) which is not UK-specific. In 
particular:

    http://business.data.gov.uk/companies/def/terms/RegisteredCompany
    rdfs:subClassOf http://www.w3.org/ns/regorg#RegisteredOrganization

So I'm hoping that there's a straightforward way for the linkage 
mechanism to work without it being UK-specific.

In case it is relevant, my:Thing is actually
