Q:

What is the UK equivalent of 'murica and 'straya?

There is a pejorative phrase in the United States for country hicks that has recently arisen: 

'murica 

Implying that that user of the phrase doesn't pronounce their words properly and doesn't care. 
Specifically it denotes people who are carefree about their appearance and behaviour, who don't live in the coastal states and are unworried about needing to come across as intelligent. 
In Australia - the equivalent phrase is:

'straya

My question is: What is the UK equivalent of 'murica and 'straya?

A:

I'd suggest Ingerland, possibly also spelt In-ger-land:

informal a jocular spelling of England, as pronounced in the chants of sports, esp football, supporters

collins
