Preventing frozen & burst pipes this winter

1 November 2024

Protecting pipes from freezing is not just a matter of convenience, but a crucial step in safeguarding properties from potentially catastrophic damage and costly insurance claims.

Frozen pipes pose a significant risk to properties across the UK, often leading to burst pipes and substantial water damage. As temperatures plummet during winter months, water inside pipes can freeze, expanding and exerting immense pressure on the pipe walls. This pressure build-up can cause pipes to rupture, resulting in what insurers term “escape of water” incidents.

The financial implications of burst pipes are considerable. According to recent data from the Association of British Insurers (ABI), the average cost of claims from freezing and burst pipes was £7500. In fact, escape of water is consistently one of the most common reasons for home insurance claims in the UK. In 2022, the ABI estimated that £804 million was paid in claims by member insurers for issues relating to burst pipes in homes.

Given these statistics, it’s clear that protecting pipes from freezing is not just a matter of convenience, but a crucial step in safeguarding properties from potentially catastrophic damage and costly insurance claims. Here are seven steps to prevent frozen pipes this winter:

Maintain a consistent temperature

Keep your premises heated to at least 12°C, even when the building is unoccupied. This helps prevent temperatures from dropping below freezing in areas where water pipes are located.

Check your stopcock and ensure people know where it is

Locate your main stopcock and ensure that it is working properly, so it can be turned off you go away or your pipes to freeze or burst. Ensure that your team knows the location of the main water stopcock and how to use it in case of an emergency. Provide clear instructions on what to do if pipes freeze or burst, including emergency contact numbers for plumbers and your insurance provider.

If your charity’s premises will be unoccupied for more than a few days during freezing weather, consider turning off the water supply at the mains and draining the system. This can prevent potential damage from undetected leaks or bursts while the property is empty.

Repair dripping taps, fittings or cisterns

Fix any dripping taps promptly, as even a small trickle can lead to frozen drainpipes.

Check outdoor water outlets, pipes and features

Disconnect and drain hosepipes and outdoor water features that are connected to external water outlets. It’s also advisable to insulate outdoor pipes using foam sleeving and fit insulated tap covers over outside taps.

Insulate vulnerable pipes

One of the most effective ways to prevent frozen pipes is proper insulation. Focus on pipes in unheated areas such as lofts, basements, and garages. Use foam pipe insulation or heat tape to cover exposed pipes, paying special attention to bends, valves, and fittings. Don’t forget to insulate water tanks as well, as these are often overlooked but are a common source of problems during cold snaps.

Seal air leaks

Identify and seal any air leaks that allow cold air to enter your property where pipes are located. This includes around doors and windows where draughts can come in from outside.

Service boilers

Schedule annual boiler services, preferably before winter sets in. A well-maintained heating system ensures efficient operation and reduces the risk of cold spots in your plumbing.

By implementing these preventive measures, you can significantly reduce the risk of frozen and burst pipes this winter, avoiding costly repairs and service disruptions.
