UK Automotive Manufacturing

What Does the EV Transition Mean for UK Engineering Businesses?

The UK automotive sector is transforming faster than at any point in a generation. New analysis from the Society of Motor Manufacturers and Traders (SMMT) identifies a £4.6 billion opportunity for UK domestic manufacturing by 2030. For precision engineering businesses, this is not background noise. It is a direct signal about where demand is heading.

The question is whether UK engineering has the capability and capacity to meet it.

A Once-in-a-Generation Shift

The SMMT’s analysis is striking in its specificity. Demand for UK-sourced automotive parts is forecast to rise by 80% by 2030. Furthermore, demand for electric motors, power electronics and drive systems is set to surge by over 350% by the end of the decade.

Battery-related production presents an equally significant opportunity. Demand is predicted to more than triple by 2030, covering battery packs, modules, cells, thermal management systems and supporting hardware. Meanwhile, automotive electronics demand is expected to more than double, driven by the rapid growth of displays, wiring systems and computing power in modern electric vehicles.

These are not gradual trends. They represent a step change in what the UK automotive supply chain needs to produce.

Production Is Already Underway

This shift is not theoretical. Next-generation volume battery electric car production began in Sunderland in December 2025. Seven new EV models are due to launch from UK plants this year alone. As a result, battery electric vehicle production volumes are expected to more than double by 2028.

Major investment commitments are already in place. JLR has committed to a £15 billion five-year strategy. Agratas is building a £4 billion gigafactory. Nissan has secured £2 billion for its UK EV programmes. Together, these signal a sustained, large-scale restructuring of UK automotive manufacturing — not a short-term response to market conditions.

Traditional Manufacturing Remains Critical Too

However, the opportunity extends well beyond new EV technologies. The SMMT is clear that traditional automotive manufacturing remains central to the UK’s industrial value. High-value opportunities continue to exist in seat assemblies, pressings, castings, chassis components and braking systems.

Demand for internal combustion engine components also remains substantial — particularly in high-performance engines, transmissions and exhaust systems. Therefore, engineering businesses do not need to pivot entirely toward electrification to benefit. The broader supply chain expansion creates opportunities across both new and established technology areas.

Where Engineering Capability Becomes Critical

New drivetrain architectures, battery systems and power electronics all require precision-engineered components, assemblies and production tooling. Moreover, they require new test infrastructure to verify performance, durability and safety before production ramps up.

This is where specialist mechanical engineering design plays a central role. As automotive manufacturers scale up EV production, they need bespoke machinery, precision tooling and custom test rigs designed around new and evolving requirements — not adapted from legacy systems. Ingenuity, analytical rigour and the ability to develop novel engineering solutions quickly become competitive advantages for supply chain partners.

What This Means in Practice

The SMMT’s Opportunity Auto campaign positions the UK as a world-class destination for automotive investment. However, realising that potential depends on engineering capability keeping pace with production ambition.

At CNR, over 35 years of precision mechanical design experience spans exactly the areas the automotive supply chain now needs most — from bespoke special purpose machinery and jigs and fixtures through to custom test rig development and detailed engineering design. As the sector scales up, the ability to design, develop and deliver precision engineering solutions with speed and confidence is exactly what programme teams need from their supply chain partners.
