Modern Consumer Units
PowerOn Electrical Engineering replaces old fuse boards with modern consumer units across Newport, Cardiff, Bristol and South Wales. A standard domestic upgrade costs £600 to £900 and includes RCBO protection, a Type 2 surge protection device, 25mm² meter tails and a 16mm² main earth. Commercial three-phase boards are typically £1,200 to £6,000+. Every board is fully tested and certified afterwards.
Your consumer unit is the heart of your electrical system. An old fuse board without RCD or RCBO protection, one showing signs of damage or overheating, or one flagged on an EICR is well worth upgrading, and it's often the first thing needed before an EV charger or a new kitchen.
Our standard domestic upgrade includes individual RCBO protection on each circuit, a Type 2 surge protection device, new 25mm² meter tails and a 16mm² main earth. Where the earthing needs improving, we can put that right too (quoted separately), including installing a TT earth electrode where it's required.
Once the new board is in, we fully test the installation and issue the right certification. We'll be honest with you: a new consumer unit improves your protection, but it doesn't automatically bring every existing circuit up to current regulations. If we find anything that needs attention, we'll tell you before we sign anything off.
We also install and upgrade commercial three-phase distribution boards, with correctly sized tails and earthing that leave room for future growth. Every installation is different, so we'll look at your system and give you a clear, competitive quote with no hidden surprises.
