Why Boiler Servicing Matters

A boiler works hard to heat your home and provide hot water. Over time, parts can wear out, filters can block, and performance can decline. An annual service ensures the system runs efficiently and prevents potentially hazardous issues, such as carbon monoxide leaks. 

Failing to service your boiler regularly may lead to: 

• Higher energy bills due to poor efficiency 
• Unexpected breakdowns during winter 
• Safety risks from gas leaks or faulty components

What To Expect At A Boiler Service

Wondering what happens during a boiler service? A Gas Safe registered engineer follows a strict process to ensure everything operates safely and efficiently. Here’s the boiler servicing process explained in detail:

1. Initial Safety Inspection

The engineer begins with a visual inspection of the boiler and the surrounding area. This includes: 

• Checking for signs of corrosion or leaks 
• Inspecting the fuel terminal for blockages or damage 
• Ensuring ventilation is adequate 

2. Boiler Casing Removal

Next, the engineer removes the boiler casing to access internal components such as the heat exchanger, burner, and combustion chamber. 

3. Cleaning Key Components

To maintain peak performance, the following parts are cleaned: 

• Heat exchanger – to prevent overheating 
• Burner and combustion chamber – for efficient ignition 
• Condensate trap – to avoid blockages that could cause leaks 

4. Functional and Safety Checks

Essential tests include: 

• Controls and safety valve testing – ensures your system responds correctly 
• Pressure and temperature gauge reading – checks operating levels 
• Carbon monoxide leak detection – critical for safety 

5. Flue Gas Analysis

Using a flue analyser, the engineer measures combustion levels to confirm that your boiler is burning fuel efficiently and safely. 

6. Electrical Connections And System Checks

All electrical connections are inspected and tightened. The engineer will also check system operation, including the thermostat, to ensure consistent heating.

7. Boiler Efficiency Tuning

If necessary, adjustments are made to improve efficiency, reducing energy use and lowering bills.

8. Service Certificate Issuance

Finally, you’ll receive a service certificate confirming the boiler has been checked and is safe for use.
