"Is there that language difference between US & UK English?"
Yes. Collective nouns, such as organizations, typically take the plural in U.K. English whereas U.S. uses the singular.
Hence, those in the U.S. would say
"The gaggle of geese is on the pond"
whereas those in the U.K. or former colonies would say
"The gaggle of geese are on the pond".
Those in the former colonies would tell others,
"Manchester United is doing well"
whereas elsewhere they'd say,
"Manchester United are doing well".

Here's one source that explains how the usage varies in U.K. English, although they assert that both plural and singular are used.

Collective nouns
There are a few grammatical differences between the two varieties of English. Let’s start with collective nouns. We use collective nouns to refer to a group of individuals.
In American English, collective nouns are singular. For example, staff refers to a group of employees; band refers to a group of musicians; team refers to a group of athletes. Americans would say, “The band is good.”
But in British English, collective nouns can be singular or plural. You might hear someone from Britain say, “The team are playing tonight” or “The team is playing tonight.”"

Here's another example. Someone in Cupertino would say,
"Apple is a great company."
Whereas everywhere else, people would say
"Apple used to be a great company." (Sorry, I couldn't resist!)
There are lots of other differences, too. Thanks to Noah Webster, who wanted an American English, spellings differ across the pond, that is, in the U.S. (honor vs. honour, e.g.).
