I don't think this upcoming cold spell will be as cold as 2010, as I remember driving to work in the Midlands and it was -11°C air temp.
This evenings charts are only showing -7°C as coldest so far in my area.
I also doubt the amount of snow we get will be as much as 2010.
But we are still 7-days away from anything really cold, and there will be upgrades and downgrades to the weather models until in the more reliable timeframe.
