Accelerating the nation’s smart meter rollout through meter financing and provision

100% Capex Funding
Calisen will finance the cost of the meter, communications gateway, installation and other necessary items with no upfront cost. Allowing for a fully funded, rapid deployment without an expensive layout.

True Partnership Approach
Calisen work alongside manufacturers to provide tailor-made solutions and achieve energy supplier goals, including the write-off of significant set-up costs and providing a holistic metering service through the Calisen Group.

Hardware & manufacturer risk
Calisen is responsible for the delivery, procurement, and maintenance of assets, leveraging strong logistics and supplier relationships to ensure timely delivery and quality control.

Off-balance sheet solution
Financed assets can be accounted for as off-balance-sheet items, thereby increasing financial flexibility for Calisen customers.

Competitive rental rates
We understand that we are not the only option for asset rental, which is why Calisen rental rates are fixed over the life of the asset.

Churn
Churn and the ability to agree on a rental agreement sit with Calisen, not the supplier. Providing suppliers with peace of mind in the case of a churn event.

Comprehensive SaaS Platform
Calisen’s custom built Asset Management system allows for full asset lifecycle tracking with 99.9% accuracy. With automated billing and compensation, Calisen suppliers can track and manage their assets at each stage of the asset life. Meaning more control with fewer complications.

As a Meter Asset Provider, Calisen owns and manages smart meters across Great Britain, funding installations and using low-cost finance to keep costs predictable for energy suppliers. Our industry-leading systems ensure suppliers only pay for the meters they use, allowing them to focus on their customers and the transition to net zero. Adam Heeley
