There are many homes around the country with faulty or outdated consumer units that are not compliant with current regulations. Upgrading your consumer unit will help to keep you safe from the risk of fires, shocks and damages. 

Modern consumer units offer vital RCD protection, along with surge protection and in some cases arc fault detection.

we oftern get asked if a new consumer unit is necessary as the one that's in has been ok for years. 
our answer is, it's better to have protection that you might never need then not to have the protection when you need it.
