Why Book a Boiler Service?

Annual boiler servicing is not just a recommendation, it’s an essential part of maintaining a safe, efficient and reliable heating and hot water system.

Improve Safety

Boilers burn fuel to generate heat. Without regular checks, faults can develop that may lead to gas leaks, carbon monoxide risks or combustion issues. An annual service ensures your appliance is operating safely and that all safety devices are functioning correctly.

Increase Efficiency

Over time, components such as burners and heat exchangers can become dirty or partially blocked. This reduces efficiency and increases fuel consumption. A serviced boiler operates more efficiently, helping to reduce your energy bills, particularly important during colder Norfolk winters.

Prevent Breakdowns

Unexpected breakdowns are inconvenient and often occur during peak usage in winter. Routine servicing allows us to identify worn parts or minor faults before they develop into costly repairs.

Protect Your Warranty

Most boiler manufacturers require annual servicing as part of their warranty conditions. Missing a service could invalidate your guarantee.

Meet Legal Requirements (Landlords)

If you rent out a property, you are legally required to have all gas appliances checked annually and provide tenants with a valid Gas Safety Certificate (often a CP12). Our Landlord Gas Safety Certificate service at £90 ensures you remain compliant with UK legislation.

Extend Boiler Lifespan

A well-maintained boiler can last significantly longer than one that is neglected. Regular servicing protects your investment and helps delay the need for replacement.

How Long Does a Boiler Service Take?

A standard boiler service typically takes up to 2 hours for most domestic properties.

The exact duration can vary depending on:

• The type of boiler (combi, system or regular)
• Whether it is gas or oil
• The age and condition of the appliance
• Accessibility of the unit
• Whether additional checks are required (for example, a landlord safety certificate)

Oil boiler servicing will take slightly longer than gas due to the additional cleaning and inspection required for oil components and filters.
For landlords booking both a boiler service and Gas Safety Certificate, the appointment may extend slightly to ensure all gas appliances within the property are thoroughly checked and documented.
