Tma Data Management

What Tma Data Management does

TMA Data Management is a UK-based, privately-held provider of energy data management software and managed services to the Great Britain energy market. Founded in 1987 and incorporated as TMA Data Management Limited in 2002, the company is headquartered in Kingston Upon Thames with an operations office in Polmont, Falkirk. TMA has been an Elexon Qualified Agent since 2006 and received full Market-wide Qualification from Elexon's Performance Assurance Board in 2025 for Market-wide Half-Hourly Settlement (MHHS) operations.

The company's core technology stack consists of proprietary, in-house developed systems — including NexFlow (its next-generation MHHS platform), a DCC Adapter for smart meter communications, REGMAN for electricity market messaging, GASMAN for gas data flows, and Dynamic Read Cycle for optimised field visit scheduling — operated on a cloud-first architecture. It manages over 6 million meter points across domestic, SME, and I&C supply points, with 99% national field service coverage across Great Britain. Core product lines include Elexon-qualified Data Collection and Aggregation (DC/DA) services in both Non-Half-Hourly and Half-Hourly modalities, Smart Data Service (SDS) and Advanced Data Service (ADS) for MHHS, an Energy Supplier CRM and Billing software suite, Carbon Compliance and Net Zero Tracking, Asset Metering for distributed energy resources, MEM services, and Consultancy for new energy market entrants.

TMA monetises through three primary commercial models — software licensing, hosted SaaS, and fully managed services — alongside consultancy, MEM services, and field operations. Its go-to-market is direct enterprise sales into GB energy suppliers (domestic, commercial, gas, electricity, renewable), Third Party Intermediaries, AMVLPs managing distributed assets, and new market entrants, supported by an active industry-events presence and a content-led pipeline. Named customers include three of the Original Big Six energy suppliers, Octopus Energy Group, SSE, and Tomato Energy, with multi-year relationships anchored by deep integration into Elexon settlement and BSC workflows.
