How we calculate the Local Service Score: We combine two sources of data: first-party data collected directly by Word of Mouth — verified customer reviews, customer-reported pricing, post-service trust-signal responses, and service awards — with suburb-level population and housing data from the Australian Bureau of Statistics 2021 Census. The score measures how well Semaphore is served for plumbers, reflecting the depth of choice, quality of service, and value for money available to residents compared to other suburbs across Australia. See our Local Service Score methodology for data sources, update frequency, and quality guardrails.
