# Battery Storage & Energy Storage Companies in United Kingdom — 2026 Industry Directory

The UK energy storage sector has experienced rapid expansion over the past five years, driven by decarbonisation targets, renewable energy integration, and the transition to electric vehicles. With over 2,000 registered companies operating across battery manufacturing, energy storage systems, recycling, and supporting infrastructure, the United Kingdom has established itself as a significant hub for battery technology and storage solutions in Europe.

This guide provides procurement professionals and business leaders with a practical overview of the industry structure, key segments, and how to locate qualified suppliers through SourceRegister's comprehensive database.

Market Overview

The UK battery storage market is valued at several billion pounds and continues to grow at double-digit rates annually. This growth is underpinned by three primary drivers: government commitment to net-zero carbon by 2050, the renewable energy capacity expansion across wind and solar, and the accelerating adoption of electric vehicles requiring both vehicle batteries and supporting infrastructure.

According to industry data, energy storage capacity additions in the UK have exceeded 1 GW annually in recent years, with stationary battery storage systems becoming economically competitive for grid support, commercial, and residential applications. The sector now employs tens of thousands of workers across manufacturing, installation, maintenance, and recycling operations.

Key Industry Segments

Battery Cell Manufacturers

Battery cell manufacturing in the UK remains limited compared to continental Europe, with most activity concentrated on battery assembly and pack manufacturing rather than cell production. Several companies operate pilot facilities and research lines, but the UK remains heavily reliant on imported cells from Asian and European suppliers.

Companies in this segment typically focus on advanced chemistry development, solid-state battery research, and niche applications. This represents both a supply chain vulnerability and an opportunity for growth as government initiatives aim to develop domestic cell manufacturing capacity.

Energy Storage Systems (BESS)

Battery Energy Storage Systems suppliers represent one of the largest segments in the UK market. These companies design, manufacture, and deploy complete storage solutions ranging from small residential units (under 10 kWh) to utility-scale installations (hundreds of MWh).

  • Grid stabilisation and frequency response services
  • Peak shaving and demand management for commercial users
  • Backup power for critical infrastructure
  • Integration with renewable energy installations

BESS providers typically operate as system integrators, assembling cells, control systems, and thermal management components into complete deployable units. Many offer accompanying software platforms for monitoring and optimisation.

Battery Testing Laboratories

Independent testing facilities verify battery performance, safety, and durability to established standards including BS EN 61427, IEC 61960, and UL standards. These laboratories are essential for product certification, quality assurance, and compliance verification before units enter the market or grid applications.

Testing services include cycle life testing, thermal abuse testing, electrical performance characterisation, and safety validation. Accreditation by UKAS (UK Accreditation Service) is standard practice for laboratories operating in this space.

Battery Recycling and Recovery

The UK battery recycling sector is growing rapidly as regulatory requirements tighten and battery volumes increase. Companies in this segment recover valuable materials—lithium, cobalt, nickel, and rare earth elements—from end-of-life battery packs while managing hazardous materials safely.

The Battery Regulations 2009 (implementing EU Directive 2006/66/EC) mandate recycling rates and material recovery targets. As EV adoption accelerates, recycling capacity requirements will intensify significantly over the coming decade.

Battery Management Systems (BMS) Providers

BMS providers develop the electronic control and monitoring systems that manage individual cell charge/discharge cycles, temperature, and safety within battery packs. These companies operate at the software and control electronics level, often supplying components to larger BESS and EV charging system manufacturers.

The BMS market is highly technical, with competition driven by accuracy, thermal management capability, and integration with vehicle or grid management systems.

Raw Material Suppliers

While the UK has minimal mining operations for battery materials, the supply chain includes companies involved in material processing, refining, and distribution. Lithium carbonate, nickel compounds, cobalt products, and graphite represent key imported materials refined and repackaged for battery manufacturers.

EV Charging Infrastructure

The EV charging sector represents the fastest-growing segment, with thousands of charge point operators and hardware manufacturers across the UK. This includes AC wallbox manufacturers, DC fast-charging hardware suppliers, networking software providers, and installation companies.

The UK Government's target of 300,000 public charging points by 2030 continues to drive infrastructure investment and supply chain development.

  • Compliance with Health and Safety at Work regulations for manufacturing operations

Frequently Asked Questions

What is the current size of the UK battery storage market?
The UK energy storage market is valued at several billion pounds with annual capacity additions exceeding 1 GW. The sector continues to grow at double-digit rates driven by renewable energy integration, net-zero targets, and EV adoption. Over 2,000 companies operate across manufacturing, installation, testing, and recycling segments.
Does the UK manufacture battery cells domestically?
Battery cell manufacturing in the UK remains limited. Most activity focuses on assembly and pack manufacturing rather than cell production. The UK imports the majority of cells from Asian and European suppliers, though government initiatives aim to develop domestic cell manufacturing capacity through new investments and research programmes.
What regulations govern battery recycling in the United Kingdom?
The Battery Regulations 2009 implement EU Directive 2006/66/EC and mandate minimum recycling rates and material recovery targets. As electric vehicle volumes increase, recycling capacity requirements will intensify. Recyclers must comply with waste management and environmental protection regulations enforced by the Environment Agency and local authorities.
