As a Trainee Cable Jointer, you’ll play a key role in maintaining and upgrading the underground electricity network that powers homes and businesses across our communities. This is a hands‑on, physically demanding role, working outdoors in all weather conditions. You’ll be part of a team installing, jointing, and repairing cables, responding to both planned works and emergency faults to ensure a safe and reliable electricity supply.

During your Jointer training programme, you’ll have the opportunity to build on your existing skills and experiences gained in other industries. The training offers a mix of technical, academic and on‑the‑job training which is provided by our dedicated training school. Our programme enables you to earn while you learn, whilst also gaining vital experience and skills as you study towards a nationally recognised qualification.

The programme can take 18 to 24 months depending on your personal capabilities and is centred on an initial course at our training school followed by buddying with an experienced cable jointing team where you will build a portfolio of work which will allow you to gain authorisations to work on the network.
