During our monthly Distributor Review Meeting this morning with Kate Palmer-Randle we discussed further developing the Qualified Electrical Construction Contractor Accreditation (QECC) from 3M Electrical in the UK.

The Qualified Electrical Construction Contractor Programme (QECC) has been set up as a partnership designed to provide valuable benefits to appointed 3M Electrical Contractor Partners.

As part of the QECC programme, contractors receive in-depth 3M product and technology training, including theoretical training on 11kV, 22kV, 33kV, 52kV & 66kV Cable Accessories, including Joints & Terminations.

Once Certified the QECC contractor can apply for a 3M 20-year MV Product Warranty) on completed projects which can be passed on to their client to offer them peace of mind on their investments and evidence Competency.

To date four companies have been geographically appointed, with a select number of new members set to qualify over the coming months.
