10 Common Causes of Burst Pipes in the UK and How to Prevent Them

A burst pipe is one of the worst plumbing emergencies any homeowner can face. It can flood your home, destroy flooring and walls, and lead to expensive repairs — not to mention the stress of losing water service when you least expect it. At Daniel Emergency Plumber, your trusted emergency plumber UK, we’ve seen how quickly a small issue can turn into a major disaster.

The good news? Most burst pipe incidents are preventable. By understanding what causes them and taking a few smart precautions, you can protect your property and avoid unnecessary damage. Here are the 10 most common causes of burst pipes in the UK — and how to stop them before they happen.

1. Freezing Temperatures

Cold weather is the number one cause of burst pipes across the UK. When water freezes inside a pipe, it expands and puts intense pressure on the metal or plastic walls, causing them to split.

Prevention:

• Insulate exposed pipes, especially in lofts, garages, and basements.
• Keep your heating on low during very cold nights, even if you’re away.
• Let taps drip slightly to keep water moving and prevent freezing.

2. High Water Pressure

Water pressure that’s too high can stress your pipes over time, causing cracks or bursts.

Prevention:

• Have a pressure regulator installed.
• Ask a professional plumber to check your home’s pressure if you notice banging noises or leaking joints.

3. Corrosion

Metal pipes corrode over time due to chemical reactions in the water or soil. This weakens them and eventually leads to leaks or bursts.

Prevention:

• Replace old metal pipes with corrosion-resistant materials such as copper or PVC.
• Schedule yearly inspections to catch early signs of rust or discoloration.

4. Tree Root Intrusion

Roots naturally seek moisture — and that often means your underground pipes. When they penetrate the pipe, they can cause cracks, blockages, and even complete pipe collapse.

Prevention:

• Avoid planting large trees near sewer or water lines.
• Have a professional use a drain camera to inspect underground pipes if you notice slow drains or gurgling noises.

5. Clogs and Blockages

A buildup of grease, hair, or foreign objects can block pipes and cause pressure to build up, leading to bursts.

Prevention:

• Never pour fat, oil, or grease down drains.
• Use drain covers to catch debris.
• Book an annual drain cleaning to keep things clear.

6. Old and Worn Pipes

Even the best plumbing systems wear out over time. Old pipes can weaken and fail, especially in properties with outdated materials like lead or galvanized steel.

Prevention:

• Schedule a plumbing inspection every few years.
• Replace aging pipes before they fail — it’s cheaper than fixing water damage later.

7. Poor Installation

Improperly installed pipes are more likely to leak or burst because of uneven pressure or weak connections.

Prevention:

• Always hire a certified, experienced plumber (like our team at Daniel Emergency Plumber).
• Avoid DIY pipe installations unless you’re fully trained.

8. Ground Movement

Soil shifts due to construction, erosion, or temperature changes can place stress on underground pipes.

Prevention:

• Use flexible piping in areas prone to ground movement.
• After any nearby construction, consider a quick inspection of your underground lines.

9. Water Hammer

Water hammer occurs when water flow stops suddenly, creating a shockwave that can damage your pipes.

Prevention:

• Install water hammer arrestors to absorb pressure surges.
• Avoid shutting off valves or taps too quickly.

10. Faulty Appliances

Leaking or malfunctioning appliances like washing machines and boilers can create back pressure or uncontrolled water flow, leading to bursts.

Prevention:

• Check your appliances regularly for leaks.
• Ensure all connections are tight and properly installed.
• Schedule annual maintenance for boilers and water heaters.
