Full System Check

A proper boiler service that goes beyond basic checks

Most boiler services are treated as a routine task, but the quality of that service directly affects how your system performs over time.

A proper boiler service looks at how your system is actually running. It involves inspecting key components, testing performance and identifying wear before it develops into a fault, ensuring everything is operating safely and efficiently.

This approach helps highlight early signs of wear or inefficiency that might otherwise go unnoticed. By addressing these early, you can avoid more serious problems and keep your system running as it should.

When servicing is carried out properly, it reduces the risk of breakdowns, protects your warranty and helps your heating system run reliably over the long term.

What You Get

What's included in a boiler service

A boiler service should be carried out methodically, not rushed. The difference is in how thoroughly the system is checked and how well it's set up to run afterwards.

Each service follows a structured checklist to ensure every part of your boiler is properly inspected, tested and recorded. This includes:

  • Full boiler inspection and safety checks
  • Gas pressure and flow testing
  • Flue and emissions checks
  • Internal component inspection and cleaning
  • Performance testing and system adjustments
  • Service record updated to maintain warranty compliance

Every stage is completed properly to ensure your boiler is safe, efficient and performing as expected.

When to Service

When your boiler should be serviced

While annual servicing is recommended, many systems go longer without being checked, which increases the risk of faults, inefficiency and warranty issues. Regular servicing ensures your system continues to perform as expected.

  • Annual servicing to maintain manufacturer warranty
  • Boilers not serviced in the last 12 months
  • Reduced performance or higher energy bills
  • Before winter to reduce the risk of breakdowns
  • Ongoing maintenance to keep the system reliable

System Performance

How servicing improves performance and efficiency

A well-maintained boiler runs more efficiently, uses less energy and provides more consistent heating and hot water throughout your home.

Regular servicing helps maintain efficiency by ensuring the system is clean, correctly adjusted and operating within the manufacturer's specifications. This not only helps reduce running costs but also improves reliability throughout the year.

Servicing also helps identify minor adjustments needed to optimise performance, making a noticeable difference in how your heating system responds day to day.
