Why this decision matters
Equipment age alone does not explain the fault, the benefit of replacement or the limits retained after repair.
Work through the actual task
- Compare diagnosed individual faults with common equipment limitations.
- Request separate repair and staged-replacement options where suitable.
- Compare total scope and ongoing costs rather than a panel or recorder price alone.
Worked example
Repeated unit faults may be local rather than a common-system failure. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: Evidence identifying which parts of the building system need work.
Limits and follow-up
Do not assume a resident can authorise changes to common property. Confirm the approval process and the person authorised to accept the work.
If the relevant check cannot be completed, record what remains uncertain and who will resolve it before work or sign-off proceeds.
