In this guide, we’ll provide 8 ways on how to stop your pipes from freezing this winter.

How to Stop Your Pipes From Freezing This Winter: 8 Ways for Homeowners & Landlords

There are several practical and effective ways to protect your home’s plumbing during cold weather. The key is combining insulation, heating control, and small daily habits that reduce the chance of water freezing inside your pipes.

1. Insulate Exposed Pipes

One of the most effective ways to prevent frozen pipes is to insulate any exposed pipework. Pipes in lofts, garages, basements, and external walls are especially vulnerable.

Using foam pipe lagging helps trap heat and prevents the water inside from dropping to freezing temperatures. It is inexpensive, easy to install, and widely available in DIY stores.

2. Keep Heating on a Low Constant Setting

It might be tempting to switch your heating off when you are out, but this can increase the risk of pipes freezing. Keeping your central heating on a low, constant temperature helps maintain warmth throughout the property.

This is particularly important during cold nights when temperatures can fall rapidly.

3. Open Cupboard Doors Under Sinks

Pipes located inside kitchen and bathroom cupboards are often in colder, enclosed spaces. Opening cupboard doors allows warm air to circulate around the pipes, helping to keep them above freezing point.

This simple habit can make a noticeable difference during cold snaps.

4. Let Taps Drip Slightly in Freezing Conditions

Allowing a slow drip from taps during extreme cold can reduce pressure build up in the pipes. Moving water is less likely to freeze, which can help protect vulnerable pipework.

This is especially useful for homes with exposed or older plumbing systems.

5. Seal Draughts Around Pipes and Walls

Cold air entering your home through gaps and cracks can quickly lower the temperature around your pipes. Sealing draughts around windows, doors, and where pipes enter the property helps maintain a more stable indoor temperature.

Simple draught proofing strips and sealant can be highly effective here.

6. Lag Outdoor Taps and Garden Pipework

Outdoor taps and garden pipes are among the first to freeze in winter. Installing an insulated tap cover and ensuring any external pipework is properly lagged will help prevent ice build up.

It is also a good idea to disconnect garden hoses before winter sets in.

7. Service Your Boiler and Check Your Heating System

A well maintained boiler plays a key role in keeping your home warm enough to protect pipes. An annual boiler service ensures your heating system is working efficiently when you need it most.

At PlusHeat, we often see frozen pipe issues linked to poor circulation or underperforming heating systems. Having a reliable system in place reduces that risk significantly and can prevent larger heating and plumbing failures later on.

This is also where a boiler cover plan can be particularly useful, giving you access to support if your boiler, central heating, or plumbing develops a fault during cold weather.

Know Where Your Stopcock Is and Act Quickly

If a pipe does freeze, knowing where your stopcock is can help you act fast and reduce damage. Turning off the water supply can limit leaks if a pipe bursts after thawing.

Every homeowner and landlord should make sure this is easy to locate and accessible at all times.

Why Do Pipes Freeze During Winters?

Pipes freeze when the temperature drops low enough for the water inside them to turn into ice. This usually happens when pipes are exposed to cold air, poorly insulated, or located in unheated areas such as lofts, garages, or external walls.

As water freezes, it expands, which increases pressure inside the pipe. This pressure is what often leads to cracks or burst pipes, causing leaks and water damage.

What Are The Warning Signs Of Frozen Pipes?

Frozen pipes often show early warning signs before they burst. These include reduced water flow from taps, unusual noises when turning on the tap, or visible frost on exposed pipework.

In some cases, taps may stop working completely even though other parts of the home still have water supply.

Acting quickly at the first sign of freezing can help prevent serious damage.

Why Choose PlusHeat Homecare Cover for Winter Protection?

Winter plumbing problems often do not happen in isolation. A frozen pipe can quickly lead to leaks, boiler strain, or central heating issues.

That is why many UK homeowners and landlords choose a PlusHeat homecare cover plan for year round protection.

With one simple plan, you can get cover for:

• Plumbing and electrics maintenance
• Boiler and controls support
• Annual boiler service included
• Central heating breakdowns
• General plumbing faults
• Electrical system issues
• Drainage problems

Having this level of protection in place means you are not left dealing with unexpected repair costs when something goes wrong during cold weather. It also helps keep your home running smoothly throughout the year, not just in winter.

Landlords in particular can benefit from our landlord cover plans, as it helps reduce tenant disruption and supports ongoing property maintenance across multiple systems.

Frequently Asked Questions

How Quickly Can Pipes Freeze In UK Temperatures?

Pipes can begin to freeze within a few hours when temperatures drop below zero, especially if they are exposed or poorly insulated.

Should I Turn My Water Off When Going Away In Winter?

If you are leaving your home for several days during freezing weather, turning off the water supply and draining the system can reduce the risk of frozen or burst pipes.

Can Smart Thermostats Help Prevent Frozen Pipes?

Yes, smart thermostats can help maintain a consistent low temperature in your home, even when you are away, which reduces the chance of pipes freezing.

Are Older Homes More At Risk Of Frozen Pipes?

Older homes can be more vulnerable due to less insulation and ageing pipework, especially if pipes run through external walls or unheated spaces.

What Should I Do If A Pipe Has Already Burst?

If a pipe bursts, turn off your stopcock immediately, switch off your heating, and contact a qualified engineer or emergency plumbing service to limit water damage.
