how long does a boiler take to service?

When planning a boiler service, it’s essential to know how long the process takes to ensure you can fit it into your schedule. In this guide, we will discuss everything you need to know about the duration of a boiler service, what the service entails, and additional factors to consider.

Boiler Service Duration

A boiler service typically takes between 40 minutes and 1.5 hours, depending on the make and model of the boiler, its age, and whether it’s a combi or conventional boiler. Older boilers may require more in-depth servicing or even replacement of parts or seals, resulting in a longer service time.

Boiler Service Components

Visual Inspection

The Gas Safe registered engineer will begin by visually inspecting the boiler to ensure it meets current requirements and standards. They will look for leaks, corrosion, and any other physical defects, both inside and outside the boiler.

Boiler Casing Removal and Component Inspection

The engineer will remove the boiler casing to inspect the main components, ensuring they are functioning correctly. They will also clean the inside of the boiler, including the burner, heat exchanger, pilot assembly (if applicable), and combustion chamber.

Flue Check

The engineer will visually inspect the boiler flue, ensuring it is installed correctly and adheres to regulations. They will also use a flue gas analyser to check that the boiler is operating as intended.

Performance Check

A gas performance check will be conducted to ensure the boiler is functioning at the correct pressure, in accordance with the manufacturer’s specifications.

Fault Detection

The engineer will run the boiler to check for faults in the heating system, controls, pilot assembly, burner, seals, safety devices, ventilation, and the boiler’s location.

Service Report

Finally, the engineer will prepare a service report detailing their findings. This report is useful for future annual services and maintaining your boiler’s warranty.

Oil Boiler Servicing

Oil boiler servicing generally takes longer than gas boiler servicing, usually lasting between 1-2 hours. The higher cost and longer duration are due to the need to inspect the oil tank storing the fuel.

When to Service Your Boiler

You should schedule a boiler service 12 months after installation to meet warranty terms and continue servicing annually. Contact a Gas Safe registered engineer if you notice any issues with your boiler, such as smoke marks, a yellow flame, overheating, dropping pressure, or a faulty pilot light.

Annual Boiler Servicing Importance

Servicing your boiler annually is crucial for several reasons:

  • Safety: Regular servicing reduces the risk of carbon monoxide leaks, ensuring the safety of your home’s occupants.
  • Preventing Breakdowns: Early detection of potential issues prevents costly repairs and maintains efficiency.
  • Maintaining Efficiency: Regular servicing ensures your boiler runs efficiently and lasts its estimated lifespan (10-15 years).

Boiler Service Cost

Boiler service costs depend on the boiler type, age, and whether parts are needed. A combi or gas boiler service ranges between £100 and £200 for an annual servicing contract or £80 to £150 for a one-off service. Keep in mind that additional costs may arise if the boiler is experiencing multiple issues.

In conclusion, a boiler service doesn’t take too long and will save you time and money in the long run. Ensure you schedule an annual boiler service to maintain efficiency and safety in your home.
