Scottish Water urges pipe protection during freeze–thaw conditions
Scottish Water advises householders and businesses to protect internal water pipes to reduce the risk of bursts, flooding, and water losses during sub-zero temperatures.

Scottish Water has issued guidance to customers across Scotland as periods of sub-zero temperatures followed by milder conditions increase the risk of frozen and burst water pipes. The utility is calling on property owners, including householders and businesses, to take preventative action to protect pipework and minimise damage to buildings and water infrastructure.
Freeze–thaw risk to water systems
When temperatures fall below zero, water inside pipes can freeze and expand. As temperatures rise, the ice thaws and contracts, which can weaken pipe walls and lead to cracking or bursting. This freeze–thaw cycle has been a recurring cause of pipe failures during recent Scottish winters.
Scottish Water reports that in the winter of 2023/24, around 3,100 bursts occurred across the national water network. More than 30% of these incidents were on customer-owned pipework within properties. Such failures not only caused flooding and property damage but also led to significant volumes of treated water being lost through leakage.
Impact on households, businesses, and the network
Burst pipes can result in substantial repair costs, disruption to water supplies, and damage to homes and commercial premises. From a system perspective, widespread bursts during cold weather place additional pressure on the water network and increase operational challenges for the utility.
Scottish Water notes that periods of rapid thaw following extended cold spells have previously triggered sharp increases in burst incidents across the country, affecting both domestic and non-domestic customers.
Preventative measures and guidance
To reduce the likelihood of pipe failures, Scottish Water recommends a straightforward approach focused on heating, insulating, and protecting pipework. Ensuring that water pipes and tanks are properly insulated is identified as one of the simplest and most cost-effective measures to prevent freezing.
The advice applies to all property types, including older buildings, new developments, holiday homes, and business premises, particularly those that may be unoccupied during cold periods.
Broader benefits of prevention
By reducing the incidence of frozen and burst pipes, customers can avoid inconvenience and repair costs while also helping to limit water losses from the distribution system. Lower leakage levels support network resilience during winter conditions and reduce the need for emergency repairs.
Scottish Water has published additional winter-related guidance, including practical tips and explanatory videos, as part of its seasonal awareness campaign. Information is available through the utility’s winter advice resources, aimed at helping customers prepare for cold weather and protect their properties and water supplies.
