Carbon Numbers is a UK-based energy management and low-carbon solutions specialist with a turnkey service to help organisations reduce energy costs, meet ESOS and SECR obligations and create people-centric building environments through intelligent building energy management.

Since 2012, we have supported public and private sector organisations to improve the way their buildings operate and perform. By using building energy management systems, secure data and advanced analytics, we help clients understand how their spaces are used and how environmental conditions such as heating, cooling, lighting, air quality and occupancy affect comfort, wellbeing and productivity.

Our work connects compliance, performance and experience. We use accurate, auditable energy and building data not only to support regulatory reporting, but to enable environments that work better for the people inside them, while reducing waste, cost and carbon.

We deliver end-to-end energy management services, including:
Energy management consultancy and compliance support
ESOS Lead Assessor services and SECR reporting
Building Energy Management Systems (BEMS) design, installation and optimisation
Secure cloud-based energy management and analytics 
Decarbonisation and Net Zero services
Managed energy services with 24/7 monitoring and reporting

Security and data integrity underpin everything we do. Our platforms and processes align with ISO 27001, ISO 50001 and Cyber Essentials standards, ensuring building and energy data is secure, reliable and audit-ready.

We work across education, healthcare, finance, commercial and public sector environments, helping organisations create efficient, resilient and people-centred buildings that support long-term sustainability.

At Carbon Numbers, building energy management is not just about saving energy. It is about creating smarter environments where people can work, learn and thrive.
