Burst pipes are the most common cause of home insurance claims in the UK (1) and cost an average of £3,500 in damage to property and contents. The expense is not the worst of it, months of disruption follows as the property is dried out and repaired.
Frost is the greatest threat to water services throughout the winter. UK Water Regulations require any fitting or apparatus to be correctly insulated to prevent frost, unless in a location that is heated for more than 12 hours a day (2). It seems obvious when you are scraping the ice from the car on a frosty morning. However, the insurance claims show that many homeowners, landlords and occupiers seem to be unaware of this requirement.
