9 Common Boiler Problems & How To Fix Them

Last Updated on February 11, 2025

A faulty boiler can disrupt your daily routine, leaving you without heating and hot water when you need it most. Identifying the problem can be challenging, and fixing it can be even trickier without expert knowledge.

At Eco Happy, we understand how crucial a well-functioning boiler is for UK homeowners and landlords. That’s why we’ve put together this expert guide on the 9 most common boiler problems and how to fix them.

Whether it’s low boiler pressure, leaks, pilot light issues, or strange noises, we’ll walk you through the causes, warning signs, and potential solutions—helping you keep your boiler running efficiently and safely.

9 Common Boiler Problems & Solutions

1. Failure To Provide Heat And Hot Water

If your boiler isn’t providing heating or hot water, it’s a clear sign of a system malfunction. This issue can be particularly frustrating, especially during cold UK winters, and can be caused by a range of underlying faults, including:

• Low water pressure – If your boiler pressure drops below 1 bar, it can prevent hot water from circulating effectively.
• Faulty thermostat – A malfunctioning thermostat may fail to communicate with your boiler, stopping it from heating water.
• Broken diverter valve – This essential component directs hot water to either your taps or radiators. If it’s stuck or broken, you may lose heating, hot water, or both.
• Airlocks – Trapped air in the system can block water flow, preventing your radiators from heating up.
• Frozen condensate pipe – In sub-zero temperatures, the external condensate pipe can freeze, causing a blockage that forces the boiler to shut down.
• Defective circulation pump – The circulating pump moves hot water around your system. If it’s failing, water won’t reach your taps or radiators.
• Incorrect thermostat settings – Your thermostat may be set too low or switched off, stopping the heating from activating.

How to Fix It

Since there are multiple possible causes, the fix depends on the underlying issue:

✅ Check your boiler pressure – If it’s below 1 bar, repressurise your boiler by using the filling loop (only if you’re confident doing so).
✅ Inspect your thermostat – Ensure it’s set correctly and has working batteries (if wireless). Try increasing the temperature to see if the boiler responds.
✅ Look for error codes – Many modern boilers display fault codes. Check your boiler’s manual or the manufacturer’s website for explanations.
✅ Bleed your radiators – If airlocks are causing the issue, bleeding your radiators may help.
✅ Check for frozen pipes – If your condensate pipe is frozen, gently pour warm (not boiling) water over it and restart your boiler.
✅ Call a Gas Safe engineer – If none of these solutions work, or if you suspect a faulty pump or diverter valve, a Gas Safe registered engineer should diagnose and repair the issue safely.

2. Unusual Boiler Noise

If your boiler is making strange noises, it can be unsettling and may indicate an underlying issue. While some sounds are harmless, others could signal serious boiler problems that require immediate attention.

Common Boiler Noises & Their Causes

• Whining or Buzzing – Often caused by a faulty burner, worn pump bearings, or electrical component issues.
• Gurgling – Usually the result of trapped air in the system or water rushing through pipes too quickly. If due to air, bleeding the radiators may resolve it. If caused by a sudden pressure rise, it needs urgent attention.
• Rattling or Banging – This could be due to limescale buildup (kettling), loose pipe fittings, a failing thermostat, or a malfunctioning pump.
• Tapping or Clicking – Often occurs as the boiler expands and contracts, but persistent noises may indicate faulty heat exchangers or ignition problems.
• Hissing – Could be a sign of overheating, often due to sludge buildup restricting water flow.

How to Fix It

✅ Bleed your radiators – If gurgling is caused by trapped air, bleeding the radiators can improve circulation.
✅ Check for limescale buildup (kettling) – If your boiler is making a rumbling or whistling noise, it could indicate limescale accumulation in the heat exchanger. A power flush or descaling treatment may be needed.
✅ Inspect the boiler pressure – A sudden increase in pressure could lead to unusual noises. Ensure it’s between 1-1.5 bar.
✅ Secure loose pipes – If rattling sounds persist, check for loose pipe fittings and secure them to prevent vibrations.
✅ Call a Gas Safe engineer – If the noise persists or is accompanied by performance issues, a Gas Safe registered engineer should inspect it to prevent further damage or potential safety risks.

3. Your Boiler Is Kettling

If your boiler is making a whistling, bubbling, or popping noise, this is known as kettling. It’s a common boiler problem caused by limescale buildup, overheating, or leaks. Left unchecked, it can lead to reduced boiler efficiency, higher energy bills, and even boiler breakdowns.

What Causes Boiler Kettling?

Limescale Buildup – Over time, mineral deposits from hard water accumulate in the heat exchanger, restricting water flow. This causes water to overheat and turn into steam, leading to the whistling or banging noise.
Overheating – If the boiler thermostat is set too high or there’s a faulty temperature sensor, the water can reach boiling point, creating steam and causing pressure fluctuations.
Leaks or Blockages – If there’s a leak in the system or air trapped in the pipes, the boiler has to work harder to maintain pressure, sometimes resulting in kettling noises.

Combi boilers are less prone to kettling due to their design, but it’s a common issue in regular and system boilers.

How to Fix Boiler Kettling

✅ Flush Out Limescale (Descaling or Power Flush)

• If kettling is due to limescale buildup, a power flush or chemical descaling treatment can clear out deposits.
• This process requires specialist equipment and should be done by a Gas Safe registered engineer.
• Preventative Tip: Installing a magnetic filter or water softener can reduce future limescale buildup.

✅ Lower the Boiler Temperature

• Check your thermostat settings and reduce the temperature to prevent overheating.
• If your thermostat isn’t responding, it may be faulty and need replacing.

✅ Bleed Radiators & Check for Airlocks

• If kettling is caused by air trapped in the system, bleeding your radiators may help.
• In severe cases, you may need an engineer to remove stubborn airlocks.

✅ Inspect for Leaks & Pressure Issues

• If your boiler pressure is too high, it can contribute to kettling. Check the pressure gauge (ideal range: 1-1.5 bar).
• Look for visible leaks in pipes, radiators, or under the boiler. If found, turn off your boiler and contact an engineer.

If your boiler continues to kettle, turn it off and seek professional help. Ignoring the issue can lead to long-term damage.

4. Leaking Boiler

A leaking boiler is one of the most common and serious boiler problems. Even a small leak can reduce efficiency, increase energy bills, and cause water damage to your property.

If left unchecked, a boiler leak can lead to pressure loss, component failure, and even gas or carbon monoxide leaks in extreme cases.

What Causes a Boiler to Leak?

High Boiler Pressure – If the boiler pressure is too high (above 2.5 bar), excess water is released through the pressure relief valve (PRV), causing a leak.

Corroded Pipes & Components – Over time, the heat exchanger, pipes, and joints can corrode due to constant exposure to water, air, and sludge buildup. Corrosion weakens the metal, leading to leaks.

Loose Joints & Pipe Connections – As the boiler heats and cools, the expansion and contraction of metal components can cause pipe fittings to loosen, leading to water leakage.

Faulty Heat Exchanger – The heat exchanger is one of the most expensive and essential boiler components. Limescale buildup, corrosion, or thermal stress can cause it to crack, resulting in significant leaks.

Additional Causes:

• Faulty seals or gaskets – Worn-out seals around the pump or diverter valve can cause leaks.
• Deteriorated expansion vessel – If the expansion vessel fails, pressure fluctuations can lead to water leakage.

How to Fix a Leaking Boiler

Before attempting any fixes, turn off your boiler and check for visible leaks. If you smell gas, call the National Gas Emergency Service on 0800 111 999 immediately.

✅ Fixing High Boiler Pressure

• Check your pressure gauge (optimal range: 1.0–1.5 bar).
• Bleed your radiators to release excess pressure.
• If pressure remains high, check the pressure relief valve (PRV) for faults and consult an engineer.

✅ Replacing Corroded Components

• If corrosion is widespread, replacing affected pipes, joints, or heat exchangers is necessary.
• A magnetic filter can help prevent future corrosion by capturing sludge and rust particles.

✅ Tightening Loose Joints & Pipe Connections

• Use an adjustable spanner or pipe wrench to gently tighten any loose fittings.
• If you’re unsure, it’s best to hire a Gas Safe registered engineer.

✅ Fixing a Faulty Heat Exchanger

• Heat exchanger replacement is a complex and costly repair. If your boiler is old (10+ years), replacing the entire boiler might be more cost-effective.

When to Call an Engineer

• If the leak is significant or coming from an internal component.
• If you suspect gas or carbon monoxide leaks.
• If you notice boiler pressure dropping frequently, indicating an unresolved issue.

5. Pilot Light Keeps Going Out

A pilot light that keeps extinguishing is one of the most frustrating boiler problems, as it prevents the boiler from igniting and providing heat.

This issue is common in older boilers with standing pilot lights, whereas modern condensing boilers use electronic ignition systems that don’t rely on a continuous flame.

Why Does the Pilot Light Keep Going Out?

Faulty or Dirty Thermocouple – The thermocouple is a safety device that detects whether the pilot light is on. If it’s dirty, worn out, or malfunctioning, it may incorrectly cut off the gas supply, extinguishing the flame.

Blocked Pilot Light Orifice – The pilot orifice can become clogged with dust, soot, or debris, reducing the flow of gas to the flame, making it weak or unstable.

Strong Draughts or Flue Issues – If your boiler is in a draughty area, a sudden gust of air may blow out the pilot light. A damaged flue or poor ventilation can also cause airflow issues, leading to pilot light instability.

Faulty Gas Valve or Regulator – If the gas valve supplying fuel to the pilot light is faulty or the gas regulator is malfunctioning, the pilot light may not receive a steady gas flow, causing it to go out.

Carbon Buildup on Burner – Over time, carbon deposits can form on the pilot burner, restricting gas flow and leading to inconsistent flames or complete failure.

How to Fix a Pilot Light That Keeps Going Out

🚨 Safety First! Before attempting any fixes, turn off the gas supply and wait a few minutes to allow any remaining gas to dissipate. If you smell gas, DO NOT attempt repairs—call the National Gas Emergency Service (0800 111 999) immediately.

✅ Fixing a Faulty Thermocouple

• If the thermocouple is faulty, it must be replaced by a Gas Safe registered engineer.
• If it’s just dirty, follow these steps:
  1. Turn off the gas supply.
  2. Locate the thermocouple (a small metal rod near the pilot flame).
  3. Remove it carefully from the control box and pilot assembly.
  4. Clean the tip using fine sandpaper or an emery cloth to remove soot and oxidation.
  5. Reattach it, turn the gas back on, and relight the pilot light.

✅ Cleaning a Blocked Pilot Light Orifice

1. Turn off the gas supply.
2. Find the pilot assembly (usually at the bottom of the boiler).
3. Carefully detach the pilot orifice (this may require unclipping or unscrewing it).
4. Use a soft brush or needle to remove debris and dust buildup.
5. Reattach the orifice, turn the gas on, and relight the pilot light.

✅ Addressing Draught or Flue Issues

• Check for open windows or vents near the boiler and close them if necessary.
• Inspect the flue for blockages (leaves, bird nests, or debris). If blocked, contact an engineer to clear it safely.

✅ Fixing a Faulty Gas Valve or Regulator

• If the gas valve is sticking or not opening properly, you’ll need an engineer to inspect and possibly replace it.
• If you experience low gas pressure throughout your home, your gas meter or regulator may be faulty—contact your gas supplier.

🚨 When to Call an Engineer

• If the pilot light goes out repeatedly despite cleaning.
• If you notice yellow or flickering flames, which could indicate carbon monoxide production.
• If the boiler is making hissing or banging noises when trying to ignite.

6. Low Boiler Pressure

Low boiler pressure is a common issue that can affect the efficiency and performance of your heating system. If the pressure gauge on your boiler reads below 1 bar, your boiler may struggle to circulate hot water effectively, leading to cold radiators, no heating, or intermittent hot water.

What Causes Low Boiler Pressure?

Leaks in the System – Even a small leak in the pipework, radiators, or boiler itself can gradually reduce pressure. Look for visible water stains, damp patches, or dripping pipes around the boiler and radiators.

Bleeding Radiators – If you’ve recently bled your radiators to remove trapped air, you may have lost too much water from the system, leading to a pressure drop.

Faulty Pressure Relief Valve (PRV) – The pressure relief valve prevents excessive pressure buildup, but if it’s faulty or worn out, it may cause water to escape from the system unnecessarily.

Expansion Vessel Issues – The expansion vessel in modern combi and system boilers maintains stable pressure. If the vessel’s air cushion is depleted or the diaphragm inside is damaged, the boiler pressure will drop.

System Wasn’t Pressurised Properly – If your boiler has been newly installed or serviced, the system may not have been fully repressurised, leading to an initial pressure drop.

How to Fix Low Boiler Pressure

🚨 Important: Before making any adjustments, check for visible leaks. If you suspect a serious leak, turn off the boiler and contact a Gas Safe registered engineer.

✅ Step 1: Check for Leaks

• Inspect around the boiler casing, pipework, and radiators for damp patches or pooling water.
• If you find a leak, tighten any loose connections or call an engineer for professional repair.

✅ Step 2: Re-pressurise the Boiler Using the Filling Loop
If there are no leaks, follow these steps to repressurise your boiler:

1️⃣ Turn off the boiler and allow it to cool.
2️⃣ Locate the filling loop (a flexible silver or black hose with valves on both ends, usually beneath the boiler).
3️⃣ Open both valves slowly, allowing water to enter the system. You’ll hear water flowing.
4️⃣ Watch the pressure gauge—once it reaches 1.2 – 1.5 bar, close both valves.
5️⃣ Turn the boiler back on and check if it operates normally.

If Your Boiler Doesn’t Have a Filling Loop
Some modern boilers have an automatic filling system, while others may require a different manual repressurisation method. Check your boiler’s user manual or contact an engineer for guidance.

🚨 When to Call an Engineer

• If the pressure keeps dropping, despite topping up the system.
• If the pressure relief valve is leaking (this may need replacing).
• If you are unsure how to repressurise your boiler safely.

7. Boiler Switches Off By Itself

When your boiler keeps switching off, it can be frustrating, especially when you’re trying to stay warm or get hot water. There are several possible causes, with low pressure being the most common, as already discussed. However, other factors can also lead to this problem, such as:

• Faulty water pump
• Interrupted fuel supply
• Closed valves

What Causes a Boiler to Switch Off by Itself?

Faulty Water Pump – The water pump is responsible for circulating hot water around your heating system. If the pump fails, the water won’t flow properly, and the boiler will shut down to protect itself from damage.

Interrupted Fuel Supply – If your boiler relies on gas or oil for fuel, an interruption in the supply, such as a blocked gas pipe or fuel shortage, will cause the boiler to turn off automatically.

Closed Valves – The isolation valves on the flow and return pipes could be closed, cutting off the water supply to the boiler. When this happens, the boiler will stop operating to avoid overheating or damage.

How to Fix It

Before you call an engineer, you can check a few things yourself to rule out some of the possible causes of the issue:

1. Check the Isolation Valves

The isolation valves are located on the flow and return pipes that connect to your boiler. These valves control the flow of water to the boiler, and if they are closed, the boiler will shut off.

To check:

• Locate the valve handles.
• Check the position of each lever: If the handle is perpendicular to the pipe, it means the valve is closed. If the handle is in line with the pipe, it means the valve is open.
• Some boilers have stickers near the valves indicating whether they should be open or closed for normal operation.

If the valves are closed, do not attempt to open them yourself unless you’re sure you know what you’re doing. Incorrect handling could cause damage to the system.

2. Inspect for a Fuel Supply Issue

If you suspect an issue with the fuel supply (gas or oil), check that:

• The gas supply valve is open (for gas boilers).
• The oil tank has enough fuel (for oil boilers).
• There are no blockages in the fuel pipe.

If you’re unsure about any of these steps or if the fuel supply appears to be the issue, call a qualified engineer for further assistance.

3. Test the Water Pump

If you suspect a faulty water pump, you may hear unusual noises such as a buzzing or grinding sound coming from the boiler, which indicates that the pump isn’t working properly.

• Listen for any strange noises while the boiler is running.
• If the pump is silent, or you hear clanking sounds, it may have stopped functioning properly.
• In this case, it’s best to contact a Gas Safe registered engineer to inspect and replace the pump if necessary.

8. Frozen Condensate Pipe

A frozen condensate pipe is one of the most common issues faced during cold weather. The condensate pipe carries excess water from the boiler to the outside drain. In freezing temperatures, this pipe can become blocked with ice, disrupting the flow of hot water to both your taps and central heating system.

Thankfully, it’s one of the easier boiler problems to fix without the need for an engineer.

What Causes a Frozen Condensate Pipe?

The condensate pipe is designed to carry away the water produced by the condensing boiler’s heat exchange process. When the temperature drops below freezing, the water inside the pipe can freeze, causing a blockage. The most likely reasons this occurs include:

• Cold weather: Extended freezing conditions, especially in winter, cause the condensate pipe to freeze.
• Improper pipe installation: Pipes installed incorrectly, such as being too exposed to cold weather, are more prone to freezing.
• Insufficient pipe insulation: If the pipe is not insulated adequately, it becomes vulnerable to freezing in colder temperatures.

How to Fix a Frozen Condensate Pipe

You don’t need to call an engineer right away to resolve a frozen condensate pipe. You can often fix this issue yourself by following these simple steps:

1. Thaw the Frozen Condensate Pipe

• Slowly pour warm (not boiling) water over the frozen section of the condensate pipe. A watering can is perfect for this task. Avoid pouring boiling water as this can damage the pipe and cause it to crack.
• Alternatively, you can apply a warm cloth, microwaveable heating pack, or hot water bottle directly to the pipe. This will gradually melt the ice without causing any damage.
• Thawing time may vary depending on the severity of the freeze, so be patient.

2. Reset Your Boiler

Once the condensate pipe has thawed, you may need to reset the boiler to restore the flow of hot water. Most modern boilers will automatically restart once the blockage has cleared. However, if your boiler doesn’t reset itself:

• Turn off the boiler, then wait for a few minutes before turning it back on.
• Check the boiler’s pressure gauge to ensure the pressure is correct, typically between 1 and 1.5 bar for most systems.
• If the boiler still doesn’t start, check the manual for any specific reset instructions or call a professional engineer.

How to Prevent a Frozen Condensate Pipe

While the quick fix can help get your system running again, it’s important to think about preventing this issue in the future. Here’s how you can protect your condensate pipe from freezing:

• Insulate the pipe: Adding pipe insulation or lagging to the condensate pipe will keep it warmer during the winter. This is especially important for pipes that are exposed to the elements.
• Install a pipe cover: Use a weatherproof pipe cover to protect the condensate pipe from the cold.
• Check your boiler regularly: Having your boiler serviced regularly will help identify potential problems before they become serious issues, such as condensate pipe freezing.

9. Boiler Doesn’t Respond To Thermostat

One of the most frustrating issues homeowners face with their boiler is when it won’t respond to the thermostat. This problem can often cause discomfort, as your home might become too hot or too cold, depending on the situation. Fortunately, the root cause is usually simple, and it’s often easy to fix.

Common Causes of a Boiler Not Responding to the Thermostat

A non-responsive thermostat is often caused by a few key factors that can be diagnosed and resolved quickly. Here are the most common causes:

1. Battery Issues: If your thermostat runs on batteries, the most frequent issue is that the batteries are weak or dead. If this is the case, simply replacing the batteries should resolve the problem.
2. Location Problems: A thermostat in a poor location can lead to inaccurate temperature readings. If the thermostat is placed near heat sources, such as radiators, or in an area with poor insulation, it might not register the room’s temperature accurately.
3. Faulty Thermostat: If the thermostat is malfunctioning or not communicating properly with your boiler, it may need to be replaced or recalibrated.

How to Fix It

1. Replace the Batteries

If the issue is a simple battery problem, replacing the batteries in your thermostat should restore the connection between the thermostat and the boiler. This is the quickest and easiest solution, and is often the cause of the issue.

• Tip: Check your thermostat’s manual for the correct battery type and replacement instructions.

2. Check the Thermostat’s Location

If replacing the batteries doesn’t work, location may be the culprit. The thermostat is designed to monitor the room’s temperature to control the heating system effectively, but if it’s placed somewhere exposed to heat, it may incorrectly register the temperature.

Here’s how to fix this:

• Move the thermostat to a location that is not too close to heat sources like radiators, direct sunlight, or electrical appliances.
• Ideally, the thermostat should be mounted on an interior wall at chest height for the most accurate readings.
• Ensure that the thermostat is placed in a well-insulated area of the home so that it isn’t affected by external temperature fluctuations.

3. Replace or Recalibrate the Thermostat

If the issue persists despite replacing the batteries and moving the thermostat, it may be time to check if the thermostat is faulty.

• Check the user manual or contact the manufacturer for troubleshooting advice.
• If recalibration doesn’t fix the issue, you may need to replace the thermostat entirely. Many modern thermostats are programmable, so you might consider upgrading to one that offers better precision and control.
• Tip: Look for smart thermostats which can automatically adjust based on your daily routines.

10. Boiler Won’t Turn Off

A boiler that won’t turn off can be a significant inconvenience, not only leading to unnecessary heating costs but also causing your home to become excessively hot. It’s one of the common boiler problems that can stem from a variety of issues.

Understanding the root causes and implementing a solution quickly is essential to getting your system back on track.

Common Causes of a Boiler That Won’t Turn Off

Several factors can prevent your boiler from switching off when it should. Let’s break down the most frequent causes:

Faulty Thermostat

A malfunctioning thermostat is often the main culprit when the boiler doesn’t respond to temperature settings. If the thermostat is stuck in the “on” position or has become inaccurate, it can send continuous signals to the boiler, causing it to run constantly.

Stuck or Faulty Valve

If a valve—such as the flow valve is stuck in the open position, the boiler may continue to produce heat even after it should have turned off. The valve is meant to control the flow of hot water, and a stuck valve can prevent the boiler from shutting down properly.

Wiring or Electrical Issues

Another potential cause could be issues with the wiring or electrical connections in your boiler. If the control systems are not working correctly, it can lead to a communication breakdown between the thermostat and the boiler, causing the system to remain on.

Pump Overrun

Some boilers have a pump overrun function, which keeps the pump running briefly after the heating has switched off to cool down the system. If the pump overrun function is malfunctioning, the boiler may fail to turn off completely.

How to Fix It

1. Check the Thermostat

Start by checking the thermostat settings. Ensure it’s set to the correct temperature and isn’t stuck on a higher setting. If the thermostat appears to be malfunctioning, you might need to replace the batteries or reset it to ensure it is properly communicating with the boiler.

• Tip: If the thermostat is located near heat sources, such as a radiator, this can cause inaccurate temperature readings, leading the boiler to stay on unnecessarily. Relocate the thermostat to a central, cooler area of the home.

2. Inspect the Valves

If the thermostat is working fine, the next step is to check the valves connected to the boiler system. A stuck valve might be preventing the boiler from switching off. To check, make sure that the isolation valve and diverter valve are functioning correctly.

If you can’t identify any obvious issues, you may need to contact an engineer to assess and fix any valve problems.

3. Examine Wiring and Electrical Components

If the issue persists, there may be electrical problems with your boiler. The wiring that connects the thermostat and boiler can sometimes become loose or damaged, causing communication problems. You should have a professional engineer inspect the wiring to ensure it is working correctly.

4. Assess the Pump Overrun Function

Check whether your pump overrun function is operating properly. If the boiler continues running even after the heating should have switched off, it could be a sign that the pump overrun function is stuck. In this case, the pump will need to be repaired or replaced by a qualified engineer.

How Much Does It Cost To Get A Boiler Repaired?

The cost of boiler repairs in the UK varies depending on the type of issue, the boiler model, and numerous other factors. However, the average price of boiler repair bills is around £100 to £500, and an average of £410 for emergency repairs.

If you’re facing frequent repairs, it might be time to consider whether your boiler is beyond economical repair. Recognising the signs of when it’s more practical to replace the unit can help you make a cost-effective decision.

How To Prevent These Common Boiler Issues

Of course, the best way to deal with any of these issues is to prevent them from happening in the first place. Here are some ways you can do that:

• Annual servicing: You probably know it needs servicing, but how often should a boiler be serviced? Well, it needs to be serviced annually by a Gas Safe registered engineer to reduce the risk of any of the issues on our list occurring.
• Maintenance: Regular boiler maintenance is essential to keep your boiler running safely and efficiently. This includes things like insulating every condensate pipe outside your home to avoid freezing and frequently inspecting the pressure gauge.
