Blocau is a collective energy buying platform that groups Australian households by location and usage to negotiate better electricity rates. Users upload their bills, set a minimum annual saving threshold, and retailers bid for the entire group, with no obligation to switch. The platform ensures privacy by only sharing aggregate cohort data with retailers.

Problem
Individual households have little negotiating power with energy retailers, as comparison sites only show published offers and sign up customers one at a time on the retailer's terms. This leaves most households on standing offers or plans that don't reflect their actual usage patterns, with no mechanism to leverage collective demand for better rates.
Solution
Blocau organizes households into defined buying groups based on postcode, usage profile, and solar status, then invites energy retailers to bid for the entire cohort. Each household sets a minimum annual saving threshold before joining, and retailers see a group with verified bills behind it, reducing acquisition friction and providing demand certainty. When a retailer's bid clears the threshold, Blocau calculates the offer's value on each household's specific usage, and the user must explicitly confirm before any switch occurs. The platform keeps individual data private, showing retailers only aggregate cohort statistics, and never automatically switches anyone.
Target Audience
Primary customers are Australian households seeking lower electricity costs without the hassle of individual comparison shopping, particularly those in postcode-defined areas where Blocau opens its waitlist.
Features
- Bill upload with privacy-first design: files are checked for type and size, then immediately dropped without storage or third-party document reading
- Postcode-based grouping using Geocoded National Address File (G-NAF) data to form cohorts by area, usage band, and solar status
- User-defined switch threshold (e.g., $150/year minimum saving) that must be cleared before any offer becomes actionable
- Retailer tender dashboard showing defined volume, usage-matched bands, solar percentage, and stated per-home thresholds
- Browser-local processing of bill figures with user review and correction before any data is used for grouping
- Aggregate-only data sharing: retailers never see names, addresses, meter identifiers, or individual bills
