Calisen Group

About Calisen Group

Founded in 2005 and headquartered in Wigan, Calisen installs, owns, and manages domestic smart meters, providing the foundational infrastructure for an increasingly digitalised and sustainable energy system.

Through its extensive network, Calisen supports accurate billing, improved energy efficiency, and greater transparency in energy consumption - all essential components of the UK’s decarbonisation targets.

Market trends and drivers

The UK’s commitment to Net Zero by 2050 continues to drive large-scale investment in smart energy infrastructure, fueling demand for smart infrastructure that enables households and businesses to better monitor and manage energy use.

Supported by the national rollout plan, energy suppliers investing in better supply data and consumer appetite for greater transparency and efficiency, smart metering remains a key enabler of the evolving energy ecosystem - positioning Calisen at the centre of the UK’s energy transformation.

Investment potential

EQT Active Core Infrastructure will support Calisen in its next phase of growth through continued smart meter deployment, growth of digital and meter health services and continuous focus on operational excellence.

Leveraging EQT’s global network and deep experience in the broad energy sector, Calisen aims to grow into adjacent infrastructure businesses – including the German smart metering market, smart water metering, and distributed energy transition assets.
