What Kaizen Energy Limited does

Kaizen Energy Limited, trading as Yuno Energy Heat, is an Irish district heating utility provider that supplies warmth and hot water to residential and commercial properties connected to its heating network. Founded in 2013 and headquartered in Santry, Ireland, the company operates under the legal entity Kaizen Energy Ltd (company number 523238) and was rebranded to Yuno Energy Heat in February 2026 as part of a positioning move under the broader Yuno Energy consumer brand. The company is privately held, with a headcount of 1–10 employees and no disclosed funding rounds, ownership structure, or management team information.

The company's core offering is its district heating supply service, delivered through a digital customer platform built on third-party infrastructure (Tridens Technology). The customer-facing technology stack comprises three channels: the Yuno Energy Heat mobile application, the online self-care portal, and a phone support line (1800 710 058). The mobile app enables customers to register accounts, view daily/weekly/monthly heat and hot water consumption, make one-off payments, and check payment history. The self-care portal provides equivalent web-based account management functionality. Together, these channels form a self-service-first utility experience focused on transparent billing and ease of use.

Kaizen Energy operates a direct-to-consumer go-to-market with a recurring subscription-style billing model for heat supply, complemented by a secondary B2B motion targeting property developers seeking sustainable heat sources for new construction projects. The primary customer segment is residential homeowners and tenants in properties already connected to the district heating network; a secondary segment is property developers, reached through direct outreach and contact forms. Marketing is conducted through the company website, the mobile app, and phone support, with no disclosed paid acquisition, partnerships, or distribution intermediaries.
