Temperatures plunged to -12C (10.4F) overnight, on the coldest night so far of Britain's big freeze.

The low was at Benson, in Oxfordshire, as the cold snap of the last eight days is forecast to last into the weekend.

The water supply to about 6,000 homes in the Rhondda valley, south Wales, continues to be affected after pipes feeding a treatment works froze.

The Met Office has issued warnings of icy roads in eastern Northern Ireland, north-west England and Kent.

The BBC Weather Centre said snow and freezing rain were set to spread from northern England and Northern Ireland to the Midlands and south-east England.

BBC forecaster Chris Fawkes said: "The thing we're most worried about this morning is icy roads in these areas."

During the day temperatures will rise to 2C (35.6F) to 3C (37.4F) across the UK and there will be more cloud.

Freezing conditions

About 30 schools are closed in Cumbria because of snow and 15 remain shut in parts of north, west and south Wales.
Meanwhile, the National Pensioner Convention warned that 12 pensioners could die every hour during the cold snap.

It called on the government to double the winter fuel allowance to £500 for every household and introduce an industry-wide tariff for older customers.

The current freezing conditions have been caused by Arctic air sweeping across Scandinavia and over the North Sea.

But temperatures are still a long way off the record low of -27C (-16.6F) in northern Scotland 14 years ago.

Weather pay-outs

Millions of pensioners and vulnerable people around the UK have become eligible for cold weather payments.
The Department for Work and Pensions said cold weather payments had now been triggered at 52 weather stations around the UK since the start of this winter.

The payment, which goes to people in receipt of certain benefits - mainly pensioners, severely disabled people and families with a young or severely disabled child - rose this year from £8.50 to £25-a-week for each spell of cold weather.

It is paid automatically to those who qualify, including the estimated 2.7m households in receipt of pension credit.
