UK Government grants £380m to Tata Group's Agratas for Somerset gigafactory as EV battery supply chain secures its largest-ever domestic public investment
The Department for Business and Trade (DBT) has announced a £380 million grant to Agratas, the battery manufacturing subsidiary of India's Tata Group, to support the construction of one of the largest gigafactories (large-scale battery manufacturing facilities designed to produce battery cells at the volumes required for electric vehicle production) in the UK. The facility is to be built in Somerset. Agratas is the battery supply partner for JLR (Jaguar Land Rover), which is also owned by the Tata Group, giving the investment a vertically integrated rationale: securing domestic battery supply for Tata's UK automotive manufacturing base rather than relying on imports from Asian producers. The UK currently has limited domestic battery cell production capacity, making gigafactory development a strategic priority under the government's industrial strategy. The grant is structured as direct funding from DBT rather than a loan or equity instrument, which simplifies the regulatory architecture but raises state aid questions under the UK Subsidy Control Act 2022 — the domestic regime that replaced EU state aid rules after Brexit. Large industrial grants of this size require transparency reporting under the Act, and the government will need to demonstrate that the subsidy meets the principles of being proportionate, necessary, and not causing undue distortions to competition. The investment is among the largest single industrial grants awarded under the current government's clean energy and manufacturing strategy.
Why this matters
A £380 million government grant to Agratas activates subsidy control, project finance, and real estate / construction legal work simultaneously. Advisers to DBT and to Agratas will need to structure the grant documentation to satisfy the UK Subsidy Control Act 2022 transparency and proportionality requirements, while Agratas's lawyers will be focused on conditions, clawback provisions, and milestone-linked disbursement structures. The 'why now' is the government's industrial strategy imperative: without domestic gigafactory capacity, UK automotive manufacturers face tariff exposure on battery imports under the UK-EU Trade and Cooperation Agreement's rules of origin requirements, which require a rising proportion of EV battery content to be produced locally. The Tata Group's dual position as both grant recipient (Agratas) and end-customer (JLR) is commercially unusual and will require careful structuring to ensure the subsidy benefits flow to the supply chain rather than generating windfall gains at the parent level.

Soundbite
Gigafactory grants are now the critical enabler of UK EV supply chain compliance with TCA rules of origin — legal work follows the subsidy.
Question you might get
“What legal obligations does the UK Subsidy Control Act 2022 impose on the government when awarding a grant of this size, and what happens if Agratas fails to meet the conditions attached to the funding?”
Full answer
The UK government has awarded a £380 million grant to Agratas, Tata Group's battery subsidiary, to build one of the UK's largest gigafactories in Somerset. The investment is driven by the rules of origin requirements in the UK-EU Trade and Cooperation Agreement, which progressively require EV battery content to be produced domestically to avoid tariffs — without this plant, JLR faces meaningful cost exposure on exports to the EU. For law firms, the deal generates subsidy control advice under the UK Subsidy Control Act 2022, project finance structuring, and construction contracts work. The broader trend is that net-zero industrial policy is now the primary driver of large-scale government procurement and grant activity in the UK, making energy transition and public law regulatory teams increasingly central to major infrastructure mandates. This suggests the pipeline for subsidy-adjacent legal work will remain strong throughout the current parliament.
