Calisen Metering Services secures new national data services contract with So Energy across Great Britain

This partnership supports data quality and operational readiness as the energy sector prepares for Market-wide Half-Hourly Settlement (MHHS).

Under the new partnership, Calisen will deploy its nationwide field service operatives to undertake meter reading and site visit activity across all of Great Britain.

Driving data excellence as the energy sector prepares for MHHS

Calisen Metering Services (CMS), part of the Calisen Group, has announced a significant new partnership with So Energy Trading Limited (So Energy) to deliver meter reading and data retrieval services across Great Britain.

So Energy, a renewable-focused supplier providing smart tariffs and solar solutions to nearly 300,000 households, is investing in improved data quality as the industry moves toward Market-wide Half-Hourly Settlement (MHHS). With this major shift on the horizon, access to high-quality, accurate meter data is becoming essential for reliable billing, regulatory compliance, and improved customer experience.

Why accurate meter data matters more than ever

As MHHS transforms the energy landscape, suppliers will rely heavily on precise consumption data to:

• Support accurate billing

• Improve customer service

• Meet evolving regulatory framework

• Enable smarter, data-driven energy management

Calisen’s proven track record in national field operations and meter reading services positions it as a key enabler of this industry-wide transformation.

A partnership built on scale, capability and trusted delivery

The new multi-year agreement is the result of a competitive tender process in which Calisen demonstrated its national scale, operational expertise, and long-standing reliability.

Under the contract, Calisen will deploy its nationwide team of field service operatives to carry out meter reading and site visit activities across Great Britain, supporting So Energy’s commitment to customer service, operational excellence and regulatory compliance.

“Our work with So Energy comes at an inflexion point for the industry. As suppliers prepare for Market-wide Half-Hourly Settlement, the importance of accurate and reliable meter data has never been greater. Calisen brings decades of experience in field operations, and a commitment to accuracy, safety and customer experience as key capabilities. These capabilities will support So Energy in delivering for its customers both now and in the future.” Joe Unsworth
Commercial Director at Calisen

Charlie Davies, CEO & Co-founder of So Energy, added: "As the world continues to face uncertainty around energy prices, So Energy remains committed to making meter-reading services as accurate and accessible as possible.

Data retrieval remains a critical component of today’s market landscape, and our partnership with Calisen enables us to provide customers with accurate billing and better consumption insights to support effective energy management.

We look forward to working closely with Calisen to elevate meter-reading services across the UK. Smart meters play an essential role in helping customers reduce their energy bills and carbon footprint, while taking greater control of their energy use. This partnership reflects a shared commitment to enabling a smarter, more resilient, data-driven energy system.

Supporting the UK’s transition to a smarter, greener energy future

With the UK energy system rapidly evolving, the partnership between Calisen and So Energy underscores the importance of high-quality meter data and robust operational delivery. Together, the organisations aim to empower customers with better insights, support regulatory change, and build a stronger foundation for a smart, low-carbon future.
