    Annual Boiler Servicing Matters, and What Happens During One

    At a glance

    Regular boiler servicing helps identify potential faults early, including issues that could lead to dangerous carbon monoxide leaks.

    A well-maintained boiler is less likely to fail unexpectedly, helping you avoid expensive repairs and inconvenient heating outages.

    Annual servicing ensures your system operates at peak performance, helping to reduce energy consumption and heating costs.

    During a standard service, engineers inspect and clean key components, check gas pressure, test safety devices, assess flue integrity, and verify water pressure.

    Most boiler warranties require annual servicing by a qualified Gas Safe registered engineer to remain valid, giving you continued peace of mind.

    Annual boiler servicing is one of those things that is easy to put off. Life gets busy, the boiler seems to be working fine and the appointment feels unnecessary. But skipping your yearly service is one of the most common mistakes homeowners make when it comes to their heating, and it can prove costly.

    A boiler that is not regularly maintained is more likely to break down, less efficient than it should be and could even pose a safety risk to your household. Carbon monoxide is an invisible, odourless gas that faulty boilers can produce, making an annual safety check genuinely important rather than just a formality.

    Here is what our engineers check during a standard boiler service:

    Gas pressure and flow rates are checked and recorded. The heat exchanger, burner and combustion chamber are inspected and cleaned. Flue integrity is assessed to make sure harmful gases are safely expelled. All seals and gaskets are examined for wear. Safety devices are tested and water pressure is checked.

    The whole process typically takes around an hour and leaves your boiler running as it should. It also keeps your manufacturer’s warranty valid, which requires annual servicing by a qualified Gas Safe registered engineer to remain in place.

    We carry out boiler servicing across Aberdeen, Westhill, Portlethen, Stonehaven and Peterculter. If you have not had your boiler looked at in the last 12 months, now is a good time to book. Get in touch with RWR Plumbing Limited and we will arrange a convenient appointment.
