The latest information from Norfolk County Council at December 2015 was:

Clearing snow and ice yourselfLast winter many people helped keep pavements and public spaces around their homes clear of snow. However, many people were put off doing so because of fears of being sued. Read on for advice on your rights and responsibilities when clearing snow and ice from public areas.
It is extremely unlikely that someone who has attempted to clear snow in a careful manner will be sued or held legally responsible if someone slips or falls on ice or snow at their property.
People should not be deterred from performing a socially responsible act, such as clearing a path of snow, by the fear that someone may subsequently get injured slipping on the path.
Though the person clearing the snow does have responsibilities when doing the job, mainly to ensure that they are not making the area more dangerous by allowing it to refreeze, it is important to note that those walking on snow and ice have responsibilities themselves. A common sense approach is encouraged.
