18th Edition Wiring Regulations BS7671:2018 (Full Course)

Price: £480.00 (Inc. VAT & Certification Fees)
Duration: 3 Days
The BS7671:2018 Requirements for Electrical Installations is due to be released at the beginning of July 2018 and is intended to come into effect on 1st January 2019.

Installations designed after 31st December 2018 will have to comply with BS7671:2018. The regulations apply to the design, erection and verification of electrical installations, also additions and alterations to existing installations. Existing installations that have been installed in accordance with earlier editions of the Regulations may not comply with this edition in every respect. This does not necessarily mean that they are unsafe for continued use or require upgrading. Virtually everyone working in electrical installation needs to be up to date with the latest wiring regulations. It is essentially the latest guidelines to show compliance with Electricity at Work Regulations. Many installers and employers require it, as do governing bodies and competent person schemes.

Course Details
The new 18th Edition Wiring Regulations BS7671:2018 electrical course will incorporate the very latest changes and additions. This qualification covers the full content of BS7671:2018 IET Wiring Regulations, 18th Edition.

This course is designed to give candidates the best possible opportunity for success. This short electrical course is intended for all persons involved in the electrical industry including operatives new to the industry and those wishing to update their knowledge from the 17th Edition to the new 18th Edition Wiring Regulation. It is also very popular with allied professionals such as contracts managers, designers, electrical engineers, consultants and surveyors.

The course is theory based, providing the under pinning knowledge and understanding of all parts of the 18th Edition Wiring Regulation BS7671:2018. Candidates are expected to complete an open book multiple choice test on the final day.

This course will deal with each individual section of the wiring regulations and there will be plenty of opportunity to practice and be assessed on your knowledge and understanding of the content. All of our staff are fully qualified teachers and assessors and have many years of hands on experience in the electrical trade.
