When water freezes it expands. If water freezes inside pipes, this expansion can cause them to burst. As the pipe then thaws, the leakage of water and subsequent damage caused can be very significant.

Burst pipes caused serious losses during the cold winters of 1963 and 1981. Since the widespread installation of central heating, they have become less common, but in the cold winter of 2010, the [https://www.abi.org.uk/Insurance-and-savings/Products/Home-insurance/Frozen-pipes Association of British Insurers] reported up to 3,500 claims for burst pipe damage every day and a pay of around £2.5 million a day. The cost of damage to households as a result of burst pipes was in the order of £7,000 per household.

Most at risk are outdoor pipes, such as garden taps or hoses, supplies to swimming pools, sprinkler systems and so on. However, inside, pipes may be at risk if they are in unheated garages, basements, attics, crawl spaces and so on.

Within buildings, frozen pipes can be prevented by:
*· Ensuring that the heating is on for at least an hour a day, or continuously during particularly cold periods. Modern heating systems may have thermostatic control that allows them to be programmed to turn on in cold weather.
*· Insulating pipes that may be at risk, although this will only delay the process, and without a heat source even insulated pipes can eventually freeze.
*· Running taps regularly.
*· Draining pipes and hoses.
*· It may be possible to add anti-freeze to some systems.
*· Opening doors or hatches to unheated areas, although this can be very costly and may result in the temperature of the rest of the building dropping.
*· If the occupants are away, arranging for property to be visited regularly.

If a pipe freezes, this may be apparent because the water stops running.

If pipes freeze:
*Check for burst pipes. This may require professional inspection of difficult to access areas.
*If there do not appear to be any burst pipes, allow the pipes to thaw naturally, or use hot water bottles or a hairdryers to accelerate the thawing
*If there are burst pipes, turn off the boiler and any other water heaters, then turn off the mains water supply at the stopcock.
*Drain the system. Be aware that drains may also have frozen.
*Repair the pipework and any damage that has been caused.
*It may be necessary to call insurers to assess damage.
