Electric Motor, Generator & Transformer Manufacturing in the UK Industry Data and Analysis
Over the five years through 2025-26, revenue is projected to edge up at a compound annual rate of 0.7% to £3.9 billion. Volatility in downstream markets, driven by weak construction and mining sectors, has weighed on demand and limited industry revenue growth. However, the manufacturing sector and utility companies have proved resilient customers, supporting industry revenue growth of 1.8% in 2025-26. This is in part due to the need to upgrade networks, replacing ageing equipment with newer, more efficient models, which has been helped by government support, for example, the Electricity Networks Strategic Framework, raising demand for industry products like new high‑voltage transformers.
