If you have a old style fuse box and are looking to update to a new one:
Amendment 3 to BS7671 IET Wiring Regulations (published January 2015) requires that consumer units (and similar switchgear assemblies) for use in domestic household premises shall have their enclosures manufactured from non combustible material (regulation 421.1.201).
As of 01st January 2016 ALL new consumer units have to be metal complying with 17th Edition Amendment 3
A typical new style is the Wylex or MK Metal 17th Edition Amendment 3 Dual RCD Consumer Unit
If you would like to have a new future proof Consumer unit please contact us to discuss your requirements.
