If your house or flat has an attic you may have been in it in the past few weeks to get your Christmas decorations down. It will not have escaped you that attics and lofts are very very cold.
Modern day insulation makes the situation even worse as less and less heat gets into the upper spaces of any property. In the olden days (pre 1980) you could tell who had the money to invest in lagging their attic because there where never any pigeons or crows sitting on their roofs!
In the southern parts of the UK the temperatures have dropped from the lows earlier on in the week.
Just a word of warning that during the exceptionally cold snap, some pipes may have burst, through expanded ice and you wont even know about it until the water thaws.
Home and business insurance policies will cover the damage caused by leaking water but not the cost of repairing the pipe.
It may well be worth just popping in to check your business premises over the Christmas break in case there is a leak which could be devastating if it continues for days and days.
