Government offers £380m to build Somerset gigafactory. The cash will help fund Agratas’ £4bn battery plant for Jaguar Land Rover. Business secretary Peter Kyle announced the support at the Bridgwater site.
Big public backing for a big private bet
The £380m grant is the largest single share of a wider government package aimed at supporting electric vehicle manufacturing in the UK.
Ministers see this as a strategic move to secure batteries for British carmakers and attract long-term investment.
The money forms part of roughly £700m of taxpayer funding announced to shore up the EV supply chain, including research and skills work. Of that wider package, the government is directing around £90m towards R&D for JLR and Nissan, and a further £100m has been earmarked for tooling and workforce training in the sector. Another slice — about £47m — will go to smaller battery innovation projects and additional research initiatives.
Peter Kyle, the business secretary, visited the site in Bridgwater to make the announcement and said the support gives firms the confidence to plan for the long term.
Where the site stands now
The factory is still mostly a steel frame, with the aim of starting battery production by the end of 2027.
The build is overseen by contractor Sir Robert McAlpine, with Severfield handling the main steel package. Costain has secured a separate contract — worth about £123m — to design and build a new junction on the M5 that will serve the site. TClarke, meanwhile, has withdrawn from the mechanical and electrical delivery team, a change that has required Agratas and its partners to reshuffle subcontracting arrangements.
Although cranes, steel, and earthworks show progress on site, the project timetable remains complicated. Agratas trimmed the footprint of its first building but says that was down to process changes that make the facility more efficient rather than cuts to planned output. The business still expects eventual capacity of about 40 gigawatt hours a year, enough for batteries for hundreds of thousands of cars.
Jobs, scale and the commercial link to JLR
Agratas projects thousands of long-term jobs once the plant reaches full scale.
Earl Wiggins, Vice President of Manufacturing Operations, UK for Agratas, said the company welcomes the government’s investment and expects over 2,200 people to be working on site over the next year, with numbers rising thereafter. The government has put a figure of roughly 4,200 jobs for the site in the long run.
The plant is owned by Agratas, a subsidiary of Tata, which also owns Jaguar Land Rover. Agratas is building the factory to supply JLR as its anchor customer — a commercial link that underpins much of the political support for keeping battery capacity in Britain. Tata told investors in 2023 the overall project could need around £4bn of investment, of which a previously undisclosed portion would come from public support.
Delays, market caution and changing forecasts
Original timetables have slipped.
Agratas had targeted 2026 for start-up, but rising caution among carmakers and delays to JLR’s own electric Range Rover have made that timeline look optimistic. Auto manufacturers globally have scaled back rapid roll-outs of new battery models after early expectations about a swift consumer switch from petrol failed to materialise. JLR pushed back the launch of its electric Range Rover and that, combined with more cautious demand forecasts across Europe, has made battery roll-out plans more tentative.
Currently, petrol prices are volatile, with recent geopolitical shocks driving fuel costs higher. That volatility could change consumer purchasing patterns in coming months, though officials and company bosses are careful not to promise a sudden swing to electric vehicles.
Why ministers backed the project
The announcement is pitched as part of an industrial strategy: ministers want domestic battery capacity so carmakers don’t have to ship cells long distances or rely entirely on overseas suppliers.
Kyle argued that clear commitments from government help attract private investment. He told journalists at the Bridgwater site that the government wants to give firms the certainty to plan not just for a year but for a decade ahead. The wider funding package — training, R&D and smaller innovation grants — is meant to shore up supply chains and skills in colleges and universities.
That pitch will face scrutiny. Competitors in Europe and Asia are already spending heavily to secure battery manufacturing and the UK’s move — even at several hundred million pounds — is modest by comparison. Still, ministers say that public backing for a strategically located plant helps lock in manufacturing and the associated high-skilled roles.
Local impacts and the supply chain
The M5 junction contract shows the local infrastructure impact.
Costain’s contract to connect the site to the motorway network shows how much civil engineering work underpins a project like this. Local contracts and steelwork have already been awarded to British firms — a point ministers are keen to emphasise — and the site will require a steady flow of materials and services as it grows.
Severfield’s role on steelwork and the reshuffle after TClarke’s exit are reminders that big projects throw up operational challenges. For the local supply chain, the plant promises long-term demand — not just during steel erection but for ongoing maintenance, logistics and specialist services.
How this fits into the broader EV picture
The Somerset plant will become only the second high-volume battery factory in the UK if it reaches the planned capacity.
The other high-volume site is run by AESC in Sunderland, and a handful of smaller cell projects are spread across Britain. Policymakers see domestic cell-making as a way to reduce exposure to overseas shocks and to keep engineering jobs onshore — but it’s expensive. Public grants help bridge early-stage risk, while companies shoulder long-term capital and operational costs.
Tata has already received other state support; the group secured a pledge of £500m to upgrade its Welsh steelworks to electric arc furnaces. That shows the government is ready to pair industrial policy with targeted investments in heavy industry — at least where there are clear supply-chain links to major employers like JLR.
Hang on though — the proof will be in the plant’s ability to ramp production on schedule and in the market’s appetite for larger numbers of EVs. For now, construction is with a mix of public cash and private finance, and with a string of commercial and civil contracts that bind the project into the regional economy.
