New Electrical Regulations – Are you covered?

By May 17, 2018June 12th, 2018Uncategorized

The new Electrical Regulations are published on 2nd July 2018 and is intended to come into effect on 1st January 2019. Installations designed after 31st December 2018 will have to comply with the new edition (BS 7671:2018 Requirements for Electrical Installations).

The Regulations apply to the design, erection and verification of all electrical installations including 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 but by employing an expert to carry out a NICEIC Electrical Installation Condition report, you will know for sure.
