What do the terms Contestable and Non Contestable works mean?

Most of the work required for a new electrical supply project is known as “contestable work”  that can be undertaken by an independent company, not just the DNO in the area.

In some instances the DNO has to complete some of the works on their equipment to enable a new development to be connected which they restrict solely to their own operators or chosen contractors, as well as the final connection. This work is known as “non-contestable works”. Read more about contestable vs non-contestable works.
