One day BS7671 (17th Edition Update) 3rd Amendment Course

A new Amendment to the 17th Edition was published on 5th January 2015. This is the 3rd Amendment to the IET Wiring Regulations. The relevant changes to the Regulations will need to be implemented with regards to design, construction and inspecting and testing from 1st July 2015. Therefore all personnel who carry out this type of work will need to be in a position to meet these requirements by this date.

To assist with this requirement, Builder Training Centres Limited is running a number of one day courses to enable personnel to understand the required changes.

The 3rd Amendment Course is aimed at anyone who already holds a 17th Edition qualification (City & Guilds 2382-10, City & Guilds 2382-12, City & Guilds 2382-20 or EAL 3719), or anyone who needs to be aware of the new requirements.

‘Knowledgeable, approachable instructor, making an enjoyable and informative course.’
