HV Transformer Replacement

Our Customer’s Challenge

The British Geological Survey experienced a critical transformer leak at its Nottingham headquarters, threatening power continuity across the site. Immediate temporary generation was required to maintain operations. The client needed a trusted engineering partner to deliver urgent support, manage risk, and provide a permanent replacement solution. They expected rapid mobilisation, technical authority, and a seamless transition from emergency power to a long-term fix.
