The main problem with the cold weather is that your pipes can freeze and should they burst, you are looking at a considerable amount of damage and cost. A good way of protecting your pipes is by lagging any exposed water pipes. Normally, the loft is the problem area so if possible, leave the hatch door open to allow some warm air to rise into the loft, this will reduce the chance of your pipes freezing.
Finding cheap home insurance can be more difficult to find at this time of year because the chances of problems and damage increase. Should the worst happen and your pipes freeze, then be sure to turn off the water supply and turn off at the stopcock and open all taps in order to drain the system.
Some families will decide to go on holiday during the winter months; if you are away for a long period of time then you should either turn off the water supply and drain the system or leave the heating on at least 10°C. Be sure to have an emergency kit available in case you lose electricity, batteries, torches, tin food and warm clothes will get you through. Ensure that you have your house insurance documents with you and before the storms hit your house, make sure you are fully covered.
