If a gas meter is repositioned from inside a domestic property to a new position outside the property, is it necessary to relocate the main equipotential bonding connection as well?
All domestic gas installations need to have main equipotential bonding in accordance with British Standard BS 7671- IEE Wiring Regulations.
Provided that the positioning of the main equipotential bonding still complies with the requirements of British Standard BS 6891 - Installation of low pressure gas pipework of up to 35 mm (R1¼) in domestic premises (2nd family gas), it would not be necessary to reposition it. However, if there is any doubt as to whether the main equipotential bond connection is correct, you need to inform the responsible person that they should have the installation checked by an electrically competent person, or their electricity supply company.
Guidance on the requirements of main equipotential bonding is given in Essential Gas Safety (GID1) from the CORGI Gas Installer Manual Series, which is available by using the following link www.corgi-direct.com
