LPG Boiler Service

Frequently Asked Questions

Q: How often should I service my LPG boiler?

At P&R Mechanical, we recommend that all LPG boilers should be serviced annually. This annual maintenance is not just best practice—it’s often a requirement for maintaining your manufacturer’s warranty and property insurance validity. LPG systems have specific safety requirements, and regular professional servicing helps ensure these standards are met. For older systems (10+ years), we sometimes recommend more frequent checks to prevent unexpected breakdowns and maintain safe operation.

Q: What does an LPG boiler service include?

Our thorough LPG boiler service begins with a visual inspection of the entire system, including external tanks and supply lines. Our Gas Safe engineers then test gas pressure and flow rates, inspect the flue for proper ventilation, examine the heat exchanger, check all safety devices including the thermocouple and pressure relief valve, clean key components, inspect electrical connections, and conduct a combustion efficiency test. We also verify proper burner operation and check for any gas leaks throughout the system. Upon completion, you receive a detailed service report and Gas Safe certificate.

Q: How much does an LPG boiler service cost?

At P&R Mechanical, our standard LPG boiler service costs £80, which includes both the callout and diagnostic assessment. This price applies during normal working hours and covers a complete service of your LPG boiler. For any additional work required beyond standard servicing, we provide clear, upfront pricing before proceeding. Unlike many competitors who advertise lower prices but add charges for “extras” that should be standard, our quoted price is transparent with no hidden fees or surprises.

Q: Is LPG boiler servicing different from natural gas servicing?

Yes, LPG boiler servicing requires specific knowledge and certification. LPG burns at different pressures and temperatures compared to natural gas, requiring adjustments to burner settings and pressure regulations. At P&R Mechanical, our engineers hold specific LPG qualifications in addition to their Gas Safe registration. They understand the unique requirements of LPG systems, including the importance of checking external storage tanks, regulators, and supply lines—elements not present in mains gas systems. This specialized knowledge ensures your LPG system receives appropriate maintenance.

Q: How can I tell if my LPG boiler needs servicing?

Signs that your LPG boiler requires immediate servicing include yellow or orange flames instead of blue, black marks or sooting around the boiler, a pilot light that frequently goes out, unusual noises during operation, increased fuel consumption, or inconsistent heating performance. At P&R Mechanical, we recommend not waiting for these warning signs to appear. Preventative annual servicing helps identify potential issues before they become noticeable problems, saving you from comfort disruptions and potentially costly emergency repairs.

Q: Is LPG boiler servicing a legal requirement?

While homeowners are not legally required to service LPG boilers, landlords must have all gas appliances, including LPG systems, checked annually by a Gas Safe registered engineer. At P&R Mechanical, we provide landlords with the necessary Gas Safety Certificate (CP12) as part of our service. For homeowners, although not a legal requirement, annual servicing is typically mandated by manufacturer warranties and insurance policies. More importantly, regular maintenance ensures your system operates safely, protecting your household from potential carbon monoxide risks.
