Boiler Servicing FAQs

A comprehensive boiler service includes visual inspection, component testing, flue gas analysis, pressure checks, internal cleaning, seal inspection, and safety device verification. The engineer will also check combustion efficiency, inspect electrical connections, and test controls and thermostats. A detailed service report is provided upon completion.
Key warning signs include unusual noises (banging, whistling, gurgling), yellow pilot light instead of blue, increased energy bills, inconsistent heating, low boiler pressure, water leaks, or visible corrosion. Any smell of gas requires immediate professional attention.
Standard boiler servicing typically costs between £80 and £120 for domestic systems. Costs vary based on boiler type, location, and whether additional repairs are needed. Some providers offer service plans starting from £15 monthly, which include annual servicing and emergency callouts.

The engineer will document all issues and provide a detailed report with recommendations. Minor issues might be fixed during the service if parts are available. For major problems, you'll receive a quote for necessary repairs. If the boiler is unsafe, it may be disconnected until repairs are completed.
