Be among the first 25 applicants.

Work at the heart of National Grid

Would you like to work for a company that makes electricity happen for every single person in England and Wales? A company that invests billions in Net Zero and creating a brighter energy future?

About The Role

On this apprenticeship you will be working towards a Level 3 EAL Subsidiary Diploma in Engineering Technologies.

You will also be paid over £24,000 a year while you train, with free food, accommodation, and travel.

The training is carried out through a combination of courses run at our Global Technical Training Centre of Excellence and on-site training on real transmission equipment in a live substation environment.

Our three-year Advanced Apprenticeship Substations will train you to become a technician in one of our 347 substations. Our substations are instrumental in the transmission of high voltage electricity over England and Wales, transforming high voltage electricity into low voltage electricity, which can be used in homes and businesses.

Our technicians play a vital role in looking after our substations. Without their careful maintenance the safe, reliable supply of electricity simply could not happen. This apprenticeship will allow you to become one of them.

You’ll be learning to do things such as maintenance work on power transformers, main connections, and terminals. You’ll be repairing different types of joints and working with things such as air systems, batteries, and environmental battery charger systems.

Following strict safety guidelines, you will carry out the maintenance, repair, and monitoring of high-voltage substation equipment. This will include circuit breakers, transformers, disconnectors, compressors and auxiliary systems.

As you can probably tell, these apprenticeships are for people who really want to get stuck in. If that sounds like it might be you, we’d be very interested in receiving your application.

Key Information

• It’s important that you deliver all works with safety being at the heart of all actions and decisions. Demonstrating safety behaviours by not walking past, following process and rules and speaking up where things don’t look right.

Location

This role is based across the Central London region. You will be expected to travel around this region. Due to the nature of this role, you need to live within a 45 minute drive of postcode NW8 8JY.

About You

You are driven and proactive, with an appetite for continuous improvement. You know how to build on your existing knowledge and skills and have the enthusiasm to run with things and to try to make them better. You’re articulate and know how to communicate appropriately with different people.

You are a flexible multitasker who can do multiple jobs at the same time and still pay great attention to detail. It doesn’t matter if you’re not academically dazzling; we want practical people with engineering mindsets who are really keen to apply themselves.

Our Advanced Apprenticeships are for people who have FIVE GCSEs, including passes in Maths and English Language (or equivalent) graded 4/C or above.

By the end of your first year, you’ll need a driving licence that permits you to drive in the UK.

You’ll need to live away from home during your training; primarily at our Eakring Training Centre in Nottinghamshire. Typically, you’ll stay on-site from Monday to Thursday and return home for the weekend (Friday to Sunday). The amount of time spent at Eakring will decrease as you progress through the programme:

• Year 1 – around 75%
• Year 2 – around 50%
• Year 3 – around 25%

What You’ll Get

We are proud to offer a starting salary of £24,306.

Benefits

• You’ll get 26 days annual leave plus statutory holidays
• You could earn a £250 bonus, depending on performance
• Double-matched pension contribution scheme
• We will pay for one professional membership subscription.
• Our My Discounts scheme offers discounts on everything from the weekly shop to your annual summer holidays. You’ll find savings on cinema tickets and at a range of high street retailers, including Sainsburys, John Lewis, Currys, Argos and Marks and Spencer.
• National Grid is committed to the personal development of our staff. You’ll be supported as you develop a wide range of business and technical skills through structured training and on the job experience. You’ll work closely with your line manager to establish and navigate through a Personal Development Plan that is tailored to your needs.
