    A well-maintained boiler is the backbone of a comfortable, energy-efficient home. Yet many homeowners in Kent overlook annual boiler servicing, often waiting until something goes wrong. In reality, regular servicing not only helps prevent breakdowns but also extends your boiler’s lifespan, reduces your energy bills, and ensures your home remains safe and compliant.

    In this guide, we’ll explain what’s included in a professional boiler service, why it’s so important, and why choosing a reputable local company like Kentish Plumbers makes all the difference.

    Why Boiler Servicing Should Never Be Skipped

    Whether you have a combi, system, or conventional boiler, annual servicing is essential. Skipping a service might seem harmless if everything appears to be working, but small issues left unchecked can lead to major (and costly) faults over time.

    Here are some of the key reasons boiler servicing is so important:

    • Improved efficiency: Boilers can lose efficiency over time. A service ensures your system is working at peak performance, helping to reduce energy usage and lower your bills.
    • Extended lifespan: Like a car, a boiler that’s regularly maintained will last much longer than one that’s neglected.
    • Fault detection: Engineers can spot potential issues early—such as leaks, worn parts, or incorrect pressure—before they escalate into serious problems.
    • Carbon monoxide safety: A faulty boiler can leak carbon monoxide, which is odourless and potentially fatal. Servicing checks for safe combustion and ventilation.

    Legal compliance for landlords: If you’re a landlord, you’re legally required to have your gas appliances checked annually and provide a Gas Safety Certificate to tenants.

    What’s Included in a Boiler Service?

    When you book a boiler service with Kentish Plumbers, you’re getting a comprehensive inspection and tune-up carried out by a fully qualified Gas Safe registered engineer.

    A typical service includes:

    1. Visual Inspection

    The engineer will check for signs of corrosion, leaks, or wear and tear, as well as ensure the installation meets current regulations and is free from obstructions.

    2. Pressure and Flow Check

    We’ll ensure your system has the correct pressure and water flow rate, and test your expansion vessel and pressure relief valve if necessary.

    3. Flue and Combustion Testing

    The flue terminal and internal flue components are checked to ensure gases are being safely expelled. A flue gas analyser is used to test combustion efficiency.

    4. Boiler Casing and Seal Checks

    The outer casing is removed to inspect internal components. We’ll check the heat exchanger, burner, main injector, spark probe, and seals.

    5. Cleaning of Internal Components

    Key components such as the burner and heat exchanger are cleaned if there is a build-up of debris, soot, or sludge.

    6. Safety Devices Tested

    Your boiler’s safety features, such as thermostats and gas valves, are tested to ensure correct operation.

    7. Condensate Trap Inspection

    Condensing boilers contain a condensate trap which must be checked and cleaned to prevent blockages or leaks.

    8. Gas Rate and Pressure Testing

    We ensure the boiler is burning the correct amount of gas and check working pressure at key test points.

    9. Service Record and Advice

    You’ll receive a service report outlining what’s been checked, any advisories, and recommendations for further work if needed.

    How Often Should a Boiler Be Serviced?

    The general rule of thumb is once every 12 months. This keeps your warranty valid, ensures compliance with your home insurance policy, and keeps the boiler operating efficiently.

    However, if you notice any of the following issues, it’s worth booking a service sooner:

    • Unusual noises like banging, gurgling, or whistling
    • Low boiler pressure
    • Radiators not heating properly
    • Pilot light frequently going out
    • Increased energy bills without explanation

    Bad smells or visible soot marks near the boiler
