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.
In the worst-case scenario, the replacement of water supply pipes is required. Traditionally this has required major excavations outside a property and usually a great deal of disruption and trauma within, over several days and possibly weeks – inevitably at high cost.
