  • Boiler Age: Older boilers require more thorough inspection and cleaning, which increases the service time.

  • Accessibility: If the heating system, gas pipework, or boiler is hard to reach, the service may take longer.

  • Engineer’s Expertise: A qualified engineer with experience servicing your specific boiler type may complete the service more efficiently.

  • Condition of Components: Issues with the expansion vessel pressure, boiler sensors, or safety devices can add to the time required for the service.

Boiler Types and Service Duration

The duration of a boiler service can vary depending on the type of boiler you have. Here’s a breakdown of the different types of boilers and their typical service durations:

  • Combi Boilers: 30 minutes to 1 hour

  • Combi boilers are a popular choice in many homes due to their compact size and ability to provide hot water on demand. Their service duration is typically shorter compared to other types of boilers because they have fewer components to inspect and clean.

  • System Boilers: 45 minutes to 1.5 hours

  • System boilers are designed to work with a separate hot water storage cylinder, providing central heating and hot water to the home. Their service duration is slightly longer than combi boilers due to the additional components, such as the hot water cylinder, that need to be checked.

  • Conventional Boilers: 1 to 2 hours

  • Conventional boilers, also known as regular boilers, feature a cold water feed in the loft and a hot water storage cylinder. Their service duration is typically longer due to the more complex system, which includes multiple components that require thorough inspection and maintenance.

  • Oil Boilers: 1 to 2 hours

  • Oil boilers require more thorough cleaning and maintenance due to the soot and debris they produce. Their service duration is typically longer than gas boilers because the engineer needs to clean the combustion chamber and other components more extensively to ensure efficient operation.

Understanding the typical service durations for different boiler types can help you plan your day more effectively when scheduling a boiler service.

What is Included in a Boiler Service?

A full boiler service covers multiple steps to ensure the boiler is in safe working order.

Visual Inspection

The engineer begins by inspecting the exterior of the boiler and surrounding heating controls for signs of leaks, corrosion, or other visible damage.

Gas Pressure and Flow Check

A flue gas analyser is used to measure the gas emissions and confirm the correct gas pressure. This ensures the boiler is burning fuel properly for efficient operation.

Casing Removal and Internal Inspection

The engineer removes the boiler casing to inspect the combustion chamber, heat exchanger, and boiler sensors. They will clean components where necessary and ensure the system is free from blockages or debris.
