Boiler Maintenance Milford Haven
Unexpected boiler breakdowns can disrupt your home’s comfort and leave you with costly repairs. Many homeowners and landlords in Milford Haven and nearby villages face issues like sudden pressure drops or intermittent hot water, often caused by overlooked boiler health problems. Proactive boiler maintenance is the key to preventing these faults before they become emergencies, ensuring your heating system runs efficiently all year round.
What Boiler Maintenance Includes
Unlike a standard annual boiler service, planned boiler maintenance involves regular checks between servicing visits to monitor the system’s ongoing condition. This approach helps identify early signs of wear and faults, allowing timely intervention. Our comprehensive maintenance covers:
- Checking and stabilising system pressure to prevent drops that cause heating interruptions
- Inspecting for kettling or unusual noises that indicate sludge or limescale buildup
- Examining condensate routes on modern boilers to avoid blockages
- Checking for corrosion or sludge accumulation within the system
- Examining condensate routes on modern boilers to avoid blockages
By addressing these elements proactively, maintenance reduces breakdown risks and extends your boiler’s lifespan.
Common Issues Prevented by Boiler Maintenance
Regular maintenance helps avoid some of the most frequent and frustrating boiler problems, including:
- Pressure drops: Often caused by leaks or faulty expansion vessels, leading to heating failure.
- Kettling and noise: Sludge or limescale inside the heat exchanger produces banging sounds and reduces efficiency.
- Intermittent hot water: Faulty valves or blockages can disrupt hot water supply.
- Condensate blockages: Particularly in modern condensing boilers, blocked condensate pipes can cause shutdowns.
Scheduled maintenance enables early detection and correction of these issues before they escalate.

Boiler Maintenance for Different Systems
Maintenance for Combi and System Boilers
Combi and system boilers rely on sealed heating circuits and pressurised water flow. Maintenance focuses on monitoring pressure stability and inspecting components such as expansion vessels, pressure relief valves, and pumps. Checking for corrosion or sludge buildup within the system is essential to prevent kettling and maintain heat transfer efficiency.
Maintenance for Oil Boilers
Oil boilers require careful attention to fuel delivery components. Our maintenance includes checking and replacing oil filters, inspecting the nozzle for proper atomisation, and assessing combustion quality to spot signs of incomplete burning or soot buildup. These checks help maintain safe operation and improve fuel efficiency without any unsafe DIY attempts.
What Homeowners Can Check Safely
While boiler maintenance should always be carried out by a Gas Safe registered engineer, there are a few simple checks homeowners can perform to support system health. You can monitor your boiler pressure gauge and top up with water if it drops slightly, following your manufacturer’s instructions. Checking visible condensate pipes for blockages or ice build-up during winter is also helpful.
However, if you notice persistent pressure drops, strange noises, or error codes, it is vital to call a professional rather than attempting repairs yourself. Sigma Plumbing & Heating’s Gas Safe registered engineers are experienced in all boiler types and can safely diagnose and resolve these problems.
What to Expect from a Planned Boiler Maintenance Visit
- Initial Assessment: Our engineer will begin by reviewing your boiler model and recent service history to tailor the maintenance checks.
- Visual and Operational Checks: We inspect all accessible components, including pressure gauges, condensate pipes, and visible pipework for signs of wear or leaks.
- System Pressure and Efficiency Tests: The pressure is stabilised if needed, and combustion or efficiency tests are conducted, particularly on oil boilers.
- Cleaning and Minor Adjustments: Where safe and appropriate, minor cleaning of condensate routes or filter replacements will be performed.
- Report and Recommendations: We will provide a detailed report highlighting any concerns and recommend repairs or servicing if necessary.
