How Often Should You Service Your Boiler?

by | May 12, 2024 | Uncategorized

Your boiler is a crucial component of your home, powering both your central heating and hot water systems. To keep it functioning flawlessly and prevent disruptions to your daily life, it’s vital to take good care of your boiler. Regular gas boiler service in Belfast can significantly enhance its safety and efficiency throughout the year, ensuring your home remains comfortable and your family safe. In this blog, we at CJT Services will explore what boiler servicing involves and how frequently you should schedule it.

Getting Your Boiler Serviced

There are three main reasons to prioritise a gas boiler service in Belfast:

  • Safety
  • Efficiency
  • Warranty Maintenance

We’ll examine each of these reasons in detail.


Your boiler, a complex and precision-engineered device, is generally safe but carries inherent risks due to its operation with gas, water, and electricity.

  • Gas: It’s exceedingly rare for a boiler to leak gas, particularly if it’s regularly serviced. However, factors like corrosion, wear and tear, electrical malfunctions, or suboptimal installation could heighten the risk of a gas leak. Gas leaks are especially perilous if they occur when the house is empty or overnight, potentially leading to dangerous accumulations.
  • Carbon Monoxide (CO): This colourless, odourless gas can be deadly and is undetectable without proper equipment. Inefficient combustion or a blocked flue can lead to CO leaks. During a gas boiler service in Belfast, engineers check for CO and other hazardous gas emissions, ensuring your home’s air remains safe to breathe.
  • Water: Boilers operate under high pressure and temperature, and a burst or leak could cause significant damage or injury. Cold water leaks pose their own risks, including electrical hazards and slip dangers.
  • Electricity: Given that electricity can ignite gas leaks and represents its own hazard, thorough inspections of all electrical connections and components are critical during a boiler service.

A comprehensive service inspection by a qualified technician in Belfast not only checks these elements but also reassures you of your boiler’s safety.


New boilers are designed for peak efficiency, but maintaining this efficiency is key to minimising energy costs. Regular servicing ensures your boiler and central heating system operate optimally, preventing you from having to overheat your home just to stay comfortable. This not only saves on heating costs but also reduces your carbon footprint.

Your Warranty

Purchasing a boiler is a significant investment in your home’s comfort and efficiency. Most new boilers come with a manufacturer’s warranty that can be quite comprehensive, often covering parts and labour for several years, which is notably generous compared to other household appliances. This warranty is designed to provide homeowners with peace of mind, ensuring that should any issues arise, the costs associated with repairs or replacements are typically covered by the manufacturer.

However, it’s crucial to note that these warranties come with a very important condition: the requirement for annual servicing. This means that to keep your warranty valid, your boiler must be inspected and serviced by a qualified professional every year. The purpose of this requirement is twofold. Firstly, regular maintenance ensures that your boiler operates at peak efficiency, which can significantly reduce your heating costs and environmental impact over time. Secondly, these inspections enhance safety by identifying and correcting potential issues before they can lead to serious problems.

Neglecting to have your boiler serviced annually can lead to the warranty being voided. If this happens, any future repairs or necessary replacements will become an out-of-pocket expense. This condition is not unique to any specific brand but is a standard practice across the boiler industry. It underscores the importance manufacturers place on maintaining a boiler’s safety and operational efficiency.

Additionally, regular servicing often includes tasks such as cleaning key components, checking for leaks or corrosion, testing control systems, and ensuring that all safety devices are working properly. These checks are crucial not just for keeping the boiler running smoothly but also for safeguarding the well-being of your household.

What Happens During an Appointment?

If you schedule annual maintenance, a typical gas boiler service in Belfast can be quite swift, lasting anywhere from 30 minutes to 2 hours. The duration largely depends on the depth of cleaning and servicing required by your boiler.

Here’s a step-by-step breakdown of the boiler service process:

  • Initial Inspection: The engineer starts by examining both the boiler unit and its surrounding area. They look for any signs of leaks, corrosion, or loose fittings, which are tell-tale indicators of potential failures.
  • Comprehensive Check: Following the manufacturer’s guidelines, the engineer performs a thorough check of the appliance. This includes everything from visual inspections to detailed combustion analysis readings. The aim is to ensure that all aspects of the boiler are functioning correctly and safely.
  • Cleaning Components: Part of the service involves physically cleaning key components of the boiler, such as the combustion chamber and filters. This is crucial for maintaining the boiler’s efficiency and safe operation.
  • Final Safety Checks and Documentation: Before concluding the service, the engineer conducts several mandatory safety checks to confirm that the boiler is operating safely. This includes filling out and updating the necessary gas safety paperwork to document the service completed.


These steps outline a general boiler service; however, your engineer might adapt the process depending on the specific model and condition of your boiler. If any serious faults are detected, the service could extend significantly longer to address these issues comprehensively.

Regular boiler service not only ensures your heating system remains efficient but also safeguards your home against the risks of malfunction, making it an essential aspect of home maintenance.

Prepare for Your Gas Boiler Service in Belfast

CJT Services recommends that you schedule a gas boiler service in Belfast annually to ensure your unit continues to operate safely and efficiently. Here’s how to prepare for your service visit:

  • Schedule Your Service: Book your next service right after the current one. Note the date in your diary to keep track of it. Make sure to confirm your appointment a few weeks in advance.
  • Prepare for the Visit: Remember, you’ll be without hot water for an hour or two during the service, though your cold water supply will be uninterrupted. This means you can still make tea or fill the kettle.
