Last night was officially the coldest night of the year so far with temperatures dropping as low as -11C in places, but forecasters warn that there may be more cold weather to come.
The Met Office has issued an amber warning for icy conditions across the country including the North, Midlands and East Anglia, until midday on Thursday and MeteoGroup have predicted there could be snow tomorrow or Wednesday.
A message on the Met Office website stated: "Large areas of England will experience colder than average conditions in the coming week, with widespread overnight frosts."
The coldest temperature measured last night was reportedly -11.2C at Loch Glascarnoch, in Scotland, which beats this year's previous record low of -9C on December 27, in Cromdale, Moray.
Snow showers and sleet expected to affect parts of Scotland and Northern Ireland, with snow extending further south.
The first heavy snow of the season has fallen in northern parts of the UK causing some delays at airports and traffic problems on the roads.
Sub zero temperatures have caused havoc across the country this week. But for some the colder it gets, the better.
