Strange Noises

Boilers generally operate quietly, so if you start hearing unusual sounds such as banging, whistling, or gurgling coming from your boiler, it is a clear indication that something is amiss. These noises can be caused by a variety of problems, including a malfunctioning pump, trapped air in the system, or a build-up of debris. Here's what you should do:

  • Step 1: Turn off your boiler. As soon as you notice strange noises, it's important to turn off your boiler to prevent any further damage.
  • Step 2: Contact a professional. Get in touch with a qualified boiler repair service and describe the noises you're hearing. They will be able to provide you with guidance on the next steps, including a potential emergency visit to assess and resolve the issue. 

Leaks and Drips

Water leaks around your boiler should never be ignored, as they can lead to serious damage and pose a safety risk. If you notice puddles, damp patches, or water stains near your boiler, it's time to take action. Here's what you should do:

  • Step 1: Shutting off your boiler is crucial to prevent any further water damage and potential electrical hazards.
  • Step 2: Contain the leak. If it's safe to do so, try to contain the leak by placing a bucket or towels underneath. This will help minimise the water damage while you wait for the professional to arrive.
  • Step 3: Contact a reputable boiler repair service immediately to schedule an emergency visit. They will be able to identify the source of the leak and perform the necessary repairs.

Irregular or Weak Heat

A properly functioning boiler should consistently provide steady and reliable heat throughout your home. If you notice uneven heat distribution, cold spots, or a decrease in overall heating performance, it's a sign that your boiler needs immediate attention. Here's what you should do:

  • Step 1: Check your thermostat. Ensure that your thermostat is set to the desired temperature and is functioning correctly.
  • Step 2: Bleed your radiators. Sometimes, trapped air in the system can cause heating issues. Try bleeding your radiators to release any air pockets.
  • Step 3: If the problem persists after performing the above steps, contact a professional boiler technician. They will be able to diagnose and repair the underlying issue, such as a faulty pump or sediment build-up.

Pilot Light Problems

The pilot light on your boiler should burn a steady blue flame. If you observe a flickering or yellow flame, it indicates an issue that requires urgent attention. A yellow flame could be a sign of a carbon monoxide leak, which is highly dangerous and potentially fatal. Here's what you should do:

  • Step 1: If you notice a yellow or flickering flame, immediately turn off your boiler and shut off the gas supply.
  • Step 2: Ventilate the area. Open windows and doors to allow fresh air to circulate and dissipate any potential carbon monoxide.
  • Step 3: Contact emergency services. If you suspect a carbon monoxide leak, leave your home immediately and contact emergency services. They will be able to assess the situation and ensure your safety.

Drop in temperature 

A sharp decline in the heating or hot water supply is another cause for concern. There are several potential causes for this, such as a faulty pump, a defective thermostat, or a system leak. Investigating the reason for the temperature drop as soon as possible is essential to avoid more harm and suffering. Identification and resolution of these problems before they become emergencies can be facilitated by routine maintenance and servicing.

Spike in energy bills

Your boiler may be operating inefficiently if your gas or electricity expenses suddenly climb. This could be the result of problems like old parts, clogged vents, or malfunctioning thermostats. An expert technician may carry out a comprehensive examination to determine the underlying source of the issue and suggest suitable remedies, which might entail boiler replacement or repairs.

Carbon monoxide 

Broken boilers can release carbon monoxide (CO), a silent killer. CO poisoning can cause headaches, nausea, dizziness, and confusion. If you encounter any of these signs or discover that your boiler is emitting a yellow flame rather than a blue one, leave the area right away and call emergency authorities. A CO detector installed in your house can serve as an early warning system and perhaps save lives.

Fluctuating pressure

Abrupt changes in boiler pressure could be the result of an expansion vessel problem, a water leak, or a pressure relief valve that isn't working properly. While too high of pressure might cause damage to the boiler or even explode it, too little pressure can interfere with the heating process.


Odours emanating from your boiler that are unpleasant, such as a sulphurous smell, may be signs of a gas leak. Gas leaks are quite harmful and need to be fixed right away. Turn off the boiler, open the windows and get in touch with a Gas Safe licenced engineer right once if you think there may be a gas leak.
