UK’s biggest EV battery gigafactory shelves expansion as Jaguar Land Rover talks stall
AESC, the UK’s largest electric-vehicle battery manufacturer, has paused plans to expand its Sunderland gigafactory after talks to supply Jaguar Land Rover (JLR) stalled. The setback reflects weaker-than-expected electric-car demand and could affect Britain’s developing EV supply chain, particularly as ministers consider reducing sales targets for new electric vehicles.
AESC currently runs two production lines supplying Nissan but has postponed a third line intended for JLR, while two further Nissan lines remain a longer-term plan. JLR had sought battery supplies before its sister company Agratas begins production at a Somerset gigafactory planned for 2027, but it has since reached agreements with other suppliers; reported disagreements involved financial commitments, costs and delivery timing. Nissan’s slower shift to electric cars and uncertainty around future production for China’s Chery have also raised questions about future battery demand in Sunderland.
- AESC has delayed Sunderland expansion after JLR supply talks stalled.
- Slower EV demand is weakening Britain’s battery manufacturing plans.
- JLR has secured alternative battery suppliers before Agratas opens.

A gigafactory is a large plant that makes batteries for electric cars. AESC’s Sunderland factory supplies Nissan, which builds cars in the city, and was expected to add more production lines to serve other customers.
Jaguar Land Rover, or JLR, is a British carmaker whose sister company Agratas is building a battery factory in Somerset, due to start production in 2027. Carmakers need reliable battery supplies as they move towards electric vehicles, while battery makers need enough orders to justify costly factory investment.
The plans matter to Britain’s developing electric-car supply chain and the jobs and investment linked to it. Demand for electric cars has been weaker than expected, and the level of future demand also depends on carmakers’ plans and government sales rules.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
The UK risks losing critical momentum in the developing EV supply chain at a time when global competition for battery manufacturing leadership is intensifying. Pausing expansion reflects insufficient confidence in Britain's green transition, particularly if coupled with reduced policy ambitions from ministers. Building a world-class battery industry requires sustained strategic investment and supportive conditions; allowing that commitment to falter undermines both long-term climate objectives and industrial competitiveness in a sector that will define manufacturing for decades.
The case against
Companies must respond honestly to market signals rather than pursue expansion premised on demand forecasts that have not materialised. Overbuilding capacity leads to inefficiency and financial strain; more realistic operations are preferable to eventual factory retrenchment. AESC's suppliers face genuine headwinds—Nissan's slower EV transition, uncertainty around Chinese production, JLR's access to alternative suppliers—that reflect authentic global market dynamics requiring measured responses. If EV demand growth has genuinely moderated, more conservative targets represent sensible policy adjustment rather than abandonment of climate goals, allowing manufacturers to maintain sustainable, profitable operations as markets mature.
