Pricing guide
Costs vary mainly with whether alarms are standalone battery/sealed units or mains‑wired and interconnected, since hardwiring usually requires more labour, materials and testing. Long cable runs, multiple roof‑void accesses, remediation of existing wiring or any required switchboard work typically push a job toward the higher end. Timing — for example after‑hours attendance — can also affect the final quote.
Power type and interconnection
Mains‑powered or hardwired interconnected alarms generally require more labour, cabling and testing than standalone battery or sealed units.
Cabling runs and roof‑void access
Long cable runs, multiple roof‑void entries or difficult access increase installation time and complexity.
Remediation and switchboard work
Repairing or replacing existing cables, or any switchboard modifications needed for hardwiring, add materially to the job scope.
Customer‑supplied alarms and materials
If you provide the alarms, material allowances in a quote may be reduced, but labour and testing costs still usually apply.
Timing and after‑hours attendance
Work carried out outside standard hours or at short notice typically attracts higher rates and may affect availability.
