Job description

Join National Grid and start a career in the electricity industry?

We’re looking for a practically skilled, can‑do individual to join our team as a Maintenance Assistant on high‑voltage equipment. No two days are the same — you’ll be out in the field, travelling between substations in a company electric vehicle, inspecting and maintaining the equipment that keeps the UK’s power flowing. From spotting early signs of wear to providing access on sites for 3rd party contractors. You’ll be part of a team that keeps things running safely and efficiently, however you’ll mainly work by yourself focussing on your own responsibilities and productivity. You’ll live within 30 minutes travel of Deeside, CH5 4BP.

This is a role for people who like to work outdoors, think on their feet, and take pride in doing the job right. You’ll undertake site routines and condition monitoring of substation equipment by following digital work instructions on an iPad, use tools with confidence, and know how to spot when something’s not quite right. We’ll give you everything you need — training, tools and PPE, and the support to build a long‑term career in the energy sector. All you need to bring is practical know‑how, reliability, and a willingness to learn.

Requirements

• Worked in an industrial or operational environment, have practical skills for inspecting/checking equipment.
• Can work on your own to targets and deadlines, experience of working to safety procedures.
• Keen eye for detail – flagging when something isn’t right.
• You can use a laptop and iPad - to follow digital work instructions.
• Full UK driving licence.
• You live within 30 minutes of Deeside, CH5 4BP.

• Generous contributory pension scheme totalling up to 18%.
• 26 days annual leave plus 8 statutory days.
