Calisen product offering
Product offeringCore offering
Calisen owns, finances, installs, and manages smart electricity, gas and water meters on behalf of UK energy suppliers and water utilities, holding approximately 40% of all smart meters installed in Great Britain (~16 million meters). Its core offering combines Meter Asset Provider services, ongoing meter equipment management, national meter reading services, and the proprietary Smart 360 network monitoring platform, supported by a nationwide field force conducting around 4 million home visits per year.
Product overview
Calisen is the UK's largest smart meter provider, operating a unified platform-plus-services model across the energy and water metering lifecycle. The core offering spans three integrated service lines: Meter Asset Provider (owning and financing ~16 million smart meters, approximately 40% of the UK market), Meter Equipment Management (ongoing maintenance and support), and Meter Reading Services (national field operations for data retrieval). These are supported by Smart 360, a technology suite providing network monitoring, outage detection, and meter health analytics to ensure the smart meter fleet operates effectively. Calisen has expanded into water metering services and international markets (Germany), while subsidiaries Plug Me In (EV charging) and Advizzo (ML/behavioral science) extend the portfolio into adjacent energy transition segments. The Calisen Smarter Energy Academy provides in-house engineering training. Together, these products enable Calisen to offer end-to-end smart metering infrastructure from asset ownership through installation, data services, and lifetime maintenance.

Calisen competitors and assessment
Company assessmentDirect peers
- Smart Metering Systems (SMS): Historically the UK's other listed Meter Asset Provider alongside Calisen, operating in the same MAP / installation / meter reading model for UK energy suppliers. Now part of the Calisen group, it remains the closest comparable for the UK MAP business model.
- BUUK Infrastructure (owner of Energy Assets): Owns and operates UK utility infrastructure including meter assets through Energy Assets, competing directly with Calisen in the MAP and multi-utility metering services market.
Broad incumbents
- Itron: Global smart metering and utility IoT vendor supplying meters, communications and analytics to electric, gas and water utilities. Comparable as a supplier into the same UK / European smart metering and AMI infrastructure ecosystem where Calisen operates.
- Landis+Gyr: Leading global manufacturer of smart electricity and gas meters and AMI infrastructure. Comparable as the meter hardware layer underpinning MAP business models like Calisen's and competing in the same smart metering programmes across Europe.
- Siemens Smart Infrastructure: Major infrastructure provider offering smart metering, grid management and energy IoT solutions to utilities globally. Comparable as a broad incumbent in the end-to-end metering and grid intelligence value chain.
- Sensus (Xylem): Smart metering and AMI vendor (owned by Xylem) with strong water and electric metering presence in the UK and Europe. Comparable as Calisen expands into water services and competes for water utility smart metering contracts.
- British Gas / Centrica: Largest UK energy supplier with significant in-house metering and field operations, and a Calisen customer as well as a competitor in some services. Comparable as the vertically integrated UK energy retailer whose smart meter rollout drives demand for Calisen's MAP services.
- Iberdrola (ScottishPower): Vertically integrated utility (ScottishPower in the UK) running its own smart meter rollout and partner programmes. Comparable as a UK smart meter customer / counterparty and as an integrated utility benchmark.
Emerging players
- Octopus Energy: Fast-growing UK energy supplier and Calisen's strategic partner (including the EMG joint vehicle for Germany). Comparable as a tech-led energy retailer investing in smart meter data capabilities and increasingly competing with Calisen in adjacent energy services.
Regional players
- Kamstrup: Danish-headquartered manufacturer of smart electricity, heat and water meters serving European utilities. Comparable as a regional smart metering hardware and AMI vendor competing in adjacent geographies and customer segments to Calisen.
