  • Boiler Service in Cardiff

    Updated: April 14, 2024

    Regular boiler service is essential to ensure its continued efficiency and longevity. To maintain your new boiler’s optimal performance over the years, scheduling routine servicing is paramount. Typically, a boiler should undergo servicing annually, with the first service taking place a year after installation. At Smart Adapt, we offer professional boiler service in Cardiff and the neighboring areas.

    Boiler servicing isn’t just about addressing existing issues; it’s also about preemptively detecting potential problems. Neglecting minor issues can lead to major complications down the line, resulting in costly repairs. It’s far safer and more economical to address issues promptly rather than allowing them to escalate.

    As your boiler ages, its performance naturally declines, and its efficiency diminishes. However, regular maintenance and servicing can significantly slow down this process, prolonging the boiler’s lifespan significantly.

    While most boilers come with a standard warranty of 5 years, some brands offer longer warranty periods. To ensure that your boiler warranty remains valid, consistent servicing is imperative. Essentially, regular servicing is a prerequisite for maintaining warranty coverage, ensuring that your boiler remains protected and operational.

    Why do I need to service my boiler?

    To prevent Carbon monoxide poisoning

    Carbon monoxide is a silent and odorless gas that can be produced by leaks from gas appliances. Detection of carbon monoxide is only possible through alarms specifically designed for this purpose. Prolonged exposure to carbon monoxide can have fatal consequences.

    To maintain a high level of efficiency

    Neglecting proper maintenance of your boiler could lead to increased utility expenses. On the other hand, a regularly serviced boiler operates more efficiently, resulting in lower energy bills and overall cost savings.

    To keep your boiler warranty valid

    To uphold the validity of most manufacturers’ warranties, it’s crucial to ensure that your boiler undergoes regular servicing. This underscores the importance of boiler service in maintaining the integrity of your heating system. Delaying or neglecting boiler service should never be an option.

    What is involved in a boiler service?

    You might be wondering what a boiler service includes. Well, we have prepared a guide to explain what is involved in the process.

    Visual inspection

    In the first stage of a boiler service, the engineer conducts a comprehensive visual inspection. This involves closely examining the exterior of your boiler for any evident signs of wear or damage. Certified engineers possess the expertise to evaluate the safety and efficiency of your boiler thoroughly, scrutinizing each component to confirm proper functionality and detect any possible issues.

    During this inspection, the engineer also checks for any leaks or corrosive damage that may have developed since the previous service. Furthermore, they assess the boiler flame to ensure it displays a normal appearance, indicating optimal functionality.

    Removal of Casing

    Following the visual inspection conducted by the Gas Safe Registered engineer, the examination proceeds to the interior components of your boiler. This phase involves removing the boiler’s casing, which serves to shield the main components from potential damage. Within this protective casing, the engineer meticulously inspects and cleans the internal parts of your boiler as needed.

    Key components such as the burner and the heat exchanger are thoroughly examined during this process, along with other essential elements crucial to the boiler’s performance.


    Ensuring the correct gas pressure is crucial as both high and low boiler pressure can lead to performance issues and impact the lifespan of your boiler. Proper gas pressure is essential for the functionality of your taps and radiators.

    Flue check

    A flue check is necessary to detect any obstructions within the flue terminals. Additionally, a flue analyser is used to assess flue emissions, ensuring they fall within safe parameters specified by the boiler manufacturer. This process helps to mitigate any potential hazards associated with emissions. It’s important to note that only a Gas Safe engineer is qualified to perform these checks.

    Checking that the boiler fires properly

    The engineer verifies that the boiler ignites correctly and operates without any faults.

    Upon completion of the checks, a comprehensive report detailing the condition of your boiler, including any identified problems or issues, will be provided. The report will also outline the necessary steps to address these issues.

    When to tell if your boiler needs servicing

    Signs Your Boiler Requires Servicing:

    Pilot Light Off:

    The pilot light serves as the ignition for your boiler, a critical function of the appliance. While common in older models, some newer boilers may still feature a pilot light. If it’s consistently off or keeps extinguishing, it signals potential trouble with your boiler.

    Yellow Light Indicating CO Leak:

    A yellow light can be a warning sign of carbon monoxide (CO) leaking, a serious safety concern.

    Unusual Noises:

    While some noise during heating cycles is normal, unfamiliar or loud noises could indicate underlying issues, such as wear and tear, especially in aging boilers.

    Overdue Service:

    Routine checks are essential for maintaining boiler efficiency, especially since issues can arise within a year. Failure to service your boiler regularly may also void its warranty.

    Unusual Odor:

    Unusual odors, along with dark marks around the boiler casing, could indicate a gas leak or other issues. Although carbon monoxide itself is odorless, leaks may produce noticeable smells.

    Inefficient Performance

    : Check if hot water taps deliver promptly and if radiators heat up effectively. Poor performance indicates inefficient operation, signaling the need for servicing to restore functionality and efficiency.

    How long does a boiler service take?

    A boiler service does not take too long to complete at all! Typically, it can take between 30 minutes or an hour to ensure that the boiler is in good working condition. However, if your boiler might need more time, your engineer will inform you of that fact. You will be provided with a Gas Safety Certificate as proof that the annual service has been made.

    How much does it cost to service a boiler in Barry?

    A boiler service cost will depend on the engineer providing the service. This could range anywhere between £60-£150, with the average being £75. You can either choose to pay the one-off fee for the annual boiler service or pay for a boiler cover plan to keep you covered throughout the year.

    What happens if I don’t service my boiler?

    Without boiler service, you will shorten the lifespan of your boiler and cause its early death. An unchecked boiler can be life threatening to you and your family. What is more, your boiler will be less efficient, consume more energy and increase the risk of constant breakdown.

    Can any plumber do a boiler service?

    Not all plumbers are qualified to work with boilers. For any work on your boiler system, you will need to employ a Gas Safe registered heating engineer to do the work.

    Does boiler service include cleaning?

    During a boiler service, the engineer will remove, inspect and clean the main components in the boiler to make sure they are fit for purpose and have no noticeable defects.

    Can I service my own boiler?

    Any boiler maintenance and troubleshooting need the right equipment and training. So it’s important to seek professional help in the case of any serious problems or any regular check.
