What Wattblock does

Wattblock is a Sydney-based independent consultancy that provides sustainability and electrification advisory services to residential strata buildings (apartment complexes and townhouse communities managed as owners corporations) in Australia. Founded in 2014 and headquartered at UNSW's Michael Crouch Innovation Centre, the company operates an explicit fee-for-advice model, forgoing commissions from product suppliers, installers, or energy retailers to position itself as a trusted intermediary in the strata electrification value chain.

The company's service portfolio spans feasibility studies (solar, battery, EV charging, hot water heat pumps), energy saving reports, NABERS for Apartment Building ratings, and competitive tendering for solar, EV charging, LED lighting, and embedded network installations. It also markets $499 inc GST self-service kits for individual apartment owners (Balcony Solar Powering Forward Kit, EV Charging Acceleration Kit), $400 ex GST one-hour Zoom consultations, and two 10-module online training courses (Solar Readiness for Strata, EV Charging Readiness for Strata). Its proprietary "Electrify Strata" initiative includes a public mapping platform covering 60,000 strata buildings across 29 NSW local government areas and a directory of 300+ vetted installers. The team, led by founder and CEO Brent Clark, reports 28 years of cumulative strata committee experience across roles of Chairperson, Secretary, and Treasurer. Underlying technologies include Allume Energy Solshare for solar sharing, Smappee electricity monitoring, and various EV charging load management systems - none manufactured by Wattblock itself.

Wattblock monetises through distributed fee-for-service engagements from free online compliance tools to paid feasibility studies and tenders. Go-to-market combines direct website engagement (online forms, surveys, paid kits), council-sponsored sustainability programs (City of Sydney Smart Green Apartments, North Sydney Futureproofing Apartments, Inner West Go Solar for Strata, plus 17 other NSW councils), and a community channel via the Electrify Strata WhatsApp community (300+ strata committee members) and a YouTube library of 150+ educational videos. Customer segments are diversified across 3,000+ strata schemes serving 125,000+ residents, 20 NSW local councils, 5 state/territory government agencies (NSW, ACT, Queensland, Western Australia, Commonwealth) and individual lot owners.
