A boiler should be serviced at least once a year, ideally within 12 months of the previous service. Annual servicing ensures the boiler runs safely and efficiently, helps prevent breakdowns, and keeps the warranty valid. Key points about boiler servicing frequency include:

• Both gas and oil boilers require annual servicing by qualified engineers.
• Landlords are legally required to have boilers and flue systems serviced every 12 months.
• Electric boilers may not require annual servicing but still benefit from professional checks.
• It is often recommended to schedule servicing during the summer months before the cold season begins.
• If you move into a new property without a known service history, get the boiler serviced promptly.
• Servicing helps identify issues such as gas leaks, inefficient heating, and internal mechanical wear.

Following this schedule provides safety, peace of mind, and extended boiler lifespan.
