Servicing vs repair

Heating engineers agree that an annual boiler service is a good idea — it reduces the likelihood of sudden failures that require more costly repairs. Here are the main differences:

Repair

• Fixes faults such as leaks, failed components, or heating issues
• Often identified during a service
• Restores full function and reliability

• Improved boiler efficiency
• Reduced energy bills
• Prevention of carbon monoxide leaks
• Lower risk of breakdowns
• Longer lifespan for your boiler and components
• Compliance with warranty conditions (many manufacturers require annual servicing)

Maintenance of your gas central heating system

To keep your central heating system in good condition:

• Book a service once a year
• Bleed radiators when cold spots develop

Good maintenance helps your system run smoothly and reduces the chance of unexpected failures.
