About ESUK
Practical electrification experience, shaped into useful support.
Electrification Services UK is led by John Riley, a railway electrification specialist with more than 25 years' experience across overhead line equipment, Electrification & Plant maintenance, construction support, fault response, technical documentation and delivery leadership.
ESUK has been created to provide practical, commercially useful support to consultants, principal contractors and railway delivery teams who need clear technical input, reliable documentation and informed challenge around electrification work.
The business is built on a simple principle: technical support should be useful to the people delivering the work. That means clear language, practical outputs, site-aware thinking and a focus on safety, reliability and delivery control.
ESUK combines railway experience with structured documentation and digital tooling. The aim is not to replace engineering judgement, but to support it with clearer information, better repeatability and practical tools that help teams understand the asset and control the work.
