Introduction
Regular boiler servicing is essential to keep your heating system running smoothly, safely and efficiently. If you live in Greatham or surrounding areas like Bordon, Alton, Liphook or Petersfield, understanding exactly what a professional boiler service should include helps you set the right expectations and spot any gaps in the work.
Why Professional Boiler Servicing Matters
A boiler service isn’t just a quick look-over. A qualified Gas Safe engineer will carry out a series of checks and tests that protect your home and ensure your system complies with manufacturer warranties and safety regulations.
1. Safety Assurance
Gas boilers must be serviced annually to detect potential carbon monoxide leaks or gas leaks early. A professional will test flues, ventilation and combustion to keep your family safe.
2. Improved Efficiency
Over time, boilers can become less efficient due to sludge build-up or faulty components. Servicing cleans critical parts, optimises performance, and can lower your energy bills.
3. Warranty Compliance
Most manufacturers require annual servicing to honour warranty terms. Skipping a service could invalidate your warranty, leaving you with expensive repair bills.
Key Steps in a Proper Boiler Service
A professional boiler service should be thorough and methodical. Here’s what you can expect:
- Visual Inspection: The engineer checks the boiler casing, pipes, and surrounding area for signs of corrosion, leaks or damage.
- Flue and Vent Check: Verifies that the flue is clear and properly sealed, ensuring safe venting of combustion gases outside.
- Gas Pressure Test: Confirms that gas pressure and gas rate settings meet manufacturer specifications.
- Component Cleaning: Key parts like the burner, heat exchanger and pilot light are cleaned to remove debris and improve efficiency.
- Combustion Analysis: A flue gas analyser measures carbon monoxide and oxygen levels to ensure safe and efficient burning.
- Safety Device Verification: Tests the thermostat, pressure relief valve, and other safety controls to make sure they operate correctly.
- System Pressure and Leak Check: Checks system water pressure, topping up or bleeding radiators as needed, and inspects for leaks in pipework.
- Controls and Thermostat Review: Ensures timers, programmers and room thermostats are functioning correctly and set optimally for your needs.
- Report and Recommendations: Provides a written service report detailing work carried out, any faults found, and recommendations for repairs or improvements.
Troubleshooting Common Boiler Issues During Service
During a service, engineers often identify issues that, if left unchecked, can lead to a heating breakdown. Common findings include:
- Low Water Pressure: Causes include leaks or recent bleeding of radiators. Your engineer will refill the system and check for leaks.
- Noisy Operation: Kettling—sounds like a kettle boiling—is usually due to limescale or sludge in the heat exchanger.
- Irregular Heating: Blocked radiators or a faulty diverter valve can cause uneven heat distribution.
- Ignition Failures: Faulty electrodes or gas valves can prevent the boiler from lighting consistently.
If your service highlights any of these, a follow-up repair or component replacement may be recommended to prevent a more costly breakdown.
Preparing for Your Boiler Service
To make the most of your annual service:
- Ensure clear access to your boiler and up to two metres around it.
- Check that any loft hatch or ceiling panel is unlocked for attic boiler access.
- List any issues you’ve noticed, such as strange noises or pressure drops.
- Confirm any warranty or service plan details, like boiler cover or manufacturer requirements.
