Your Details


This online training module is designed to summarise the changes for existing users, enabling them to identify these where NEC4 will become their contract of choice.


NEC3 has made a significant contribution to the engineering and construction industry in particular, to do things differently and better. It is 12 years since NEC3 was published, and through a network of more than 300 companies who are regularly engaged via the NEC3 Users’ Group, and from clients generally, the NEC team has received feedback and requests for features and contract solutions to support on-going improvement.

NEC4 has taken the successful NEC3 contract suite and enhanced it, with some new features and some new forms of contract. All of the changes are a direct result of feedback from industry, to support methods and provide solutions which clients are demanding.


Approximately 60-75 minutes.

The length of time taken varies depending on how quickly individuals study and absorb the material.

Please note that the licence is valid for 6 months only from date of purchase.

Successful completion of this course will award you 15 credit points toward your Online Academy qualification.
