Boiler Servicing

You should service your boiler once a year to maintain its efficiency, safety, and manufacturer warranty. Landlords are legally required to service tenants’ boilers annually.

A standard service takes 30-60 minutes, but it may take longer if the engineer finds any issues or if the boiler requires additional cleaning.

Yes, for gas boilers, the engineer must be Gas Safe registered. Always ask for their credentials before hiring.

1. Visual Inspection

• Checking for leaks, corrosion, and visible damage.
• Ensuring the flue and ventilation are unobstructed.
• Looking for signs of wear and tear.

2. Component Checks

• Examining the heat exchanger, burner, and ignition system.
• Checking seals and joints for leaks.
• Inspecting the pressure levels and flow rate.
• Testing thermostats and controls.

3. Cleaning & Maintenance

• Cleaning the burner, heat exchanger, and other key parts.
• Removing any debris or blockages in the system.
• Checking and cleaning the condensate trap (for condensing boilers).

4. Safety Tests

• Carbon monoxide (CO) and gas leak checks.
• Testing the flue emissions to ensure proper combustion.
• Ensuring the boiler is properly ventilated.

5. Efficiency & Performance Testing

• Measuring gas pressure and flow.
• Checking the radiators and heating efficiency.
• Identifying potential faults or efficiency issues.

6. Report & Recommendations

• A service report detailing what was checked and any necessary repairs.
