Why this decision matters
A low initial price can be misleading when a required feature depends on an unlisted recurring service.
Work through the actual task
- Clarify building costs versus individual upgrade costs.
- Ask about platform renewals, replacements and future credential charges.
- Request an itemised first-year and recurring cost summary with renewal conditions.
Costs to separate for this system
Building work may include common hardware, unit equipment, cabling, appointments, programming and resident communications. Compare the number of entrances/units covered and the treatment of inaccessible units. Request a clear staged scope where a complete changeover cannot happen in one visit.
Worked example
Residents may pay separately for an optional unit screen. This is a hypothetical example, not a completed customer installation.
The useful evidence at the end of this example is: A cost/responsibility schedule that residents can understand.
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.
