Commercial Plumbing Services in Perth, WA

Affinity Plumbing & Gas has been delivering commercial plumbing services to Perth businesses, property managers, and developers for years. We understand that commercial clients have different expectations to a residential call-out — tighter timelines, compliance requirements, and the need for clear communication throughout. We’re built for that.

From routine maintenance across a strata portfolio to a full commercial fitout, our licensed team approaches every project the same way: on time, to standard, and with the documentation to back it up.

Planned Preventative Maintenance

Reactive plumbing is expensive. A planned preventative maintenance (PPM) program keeps your assets running, your compliance up to date, and your costs predictable. We build and maintain asset registers for our commercial clients — documenting every piece of plumbing infrastructure on site, its service history, and its next scheduled maintenance date. No guesswork, no surprises.

Service contract clients receive priority response — a licensed plumber on site within 2 hours for emergency call-outs.

Experienced with Commercial Property Management

If you manage commercial or strata properties, you need a plumbing contractor you can hand a problem to and know it will be dealt with properly. We coordinate directly with tenants when needed, provide clear job reports, and keep you informed — so you’re not chasing us for updates. We work with property managers, strata companies, facilities teams, retailers, office buildings, and hospitality venues across Perth.

Licensed, Insured, and Accountable

All work is carried out by fully licensed plumbers and gas fitters (PL9320 / GF015900). We’re comprehensively insured, and every job comes with the compliance documentation you need. Pricing is transparent — you’ll always have a quote before we start.
