It's a working class British habit, quite common in the north of England and also in parts of Scotland. It stems from the days when in every close knit street where people all knew each other, there would be dozens of people of the same name, so if you said 'I'm going to see our Rita' everybody knew you meant your sister Rita, not that other Rita who worked in the corner shop, etc.
It's not so common as it used to be however and to have it used as far south as Coventry (where the series is set) seems a little bit unusual and possibly in order to emphasise Rose's working class background. It is/was used in the midlands and southern England but far less so. To use it as a direct term of address 'Hello our Rose' etc is also much less common and again is used more for dramatic effect.
'Monsters? We're British!'
