Utility Warehouse Tech Stack

Multi-service home bundler with energy, broadband, mobile, and insurance

Utilities London 1,001–5,000 employees Founded 1997 Public Company

Utility Warehouse bundles essential household services—energy, broadband, mobile, and insurance—into a single monthly bill, distributed through a partner-led network across the UK. The tech stack reveals a modern, distributed architecture: Go and Rust for performance-critical services, Kafka for event streaming, Postgres and CockroachDB for transactional workloads, and a heavy analytics footprint (BigQuery, Snowflake, dbt, Looker). Hiring is heavily weighted toward product and marketing roles (23 of 48 total, posted last 30 days), with engineering and data support roles, suggesting a product-driven scaling phase focused on acquisition and experience redesign.
