Please note:
There are different cards regarding LV cable jointing – Assistant Jointer, Jointer (Green stripe) and Jointer (Gold Stripe).

The Gold card is only available to those who have met the NVQ Level 3 requirement plus completed the NET Assessment.

The Jointer (Green stripe) is for those who have only completed the NET Assessment.

Assistant Jointer is available on the same requirements as Electrical Labourer or Cable Hand (Level 1 Health and Safety or underpinning technical certificate). Obviously, much with an Electrical Labourer, the role and the expectations of what someone should be able to undertake will differ and this is not a skilled role, but a position for people to gain the necessary experience while in training.

It is not possible to get a Jointer’s card (at either grading of Jointer or Approved Jointer) without the NET Assessment.

Without the NET assessment the card will say Assistant Jointer rather than Jointer.

Charge rates:

  • Full assessment (first sitting or resit of all sections) = £635 (2 Assessments at the same time/date) or if only 1 person £900.
  • Section A cable jointing (this is the section that uses the material so larger cost) = £485.
  • Section B inspect and test = £130.
  • Section C knowledge exam = £130.
