Modern Consumer Unit Replacement

Your consumer unit (fuse board) is the heart of your home's electrical system. If your property still has an old-style fuse box with rewirable fuses or an early MCB board without RCD protection, upgrading to a modern consumer unit is one of the most important safety improvements you can make.

Modern consumer units feature RCDs (Residual Current Devices) or RCBOs that instantly disconnect the supply if they detect a fault, significantly reducing the risk of electric shock and electrical fires. The 18th Edition wiring regulations (BS 7671:2018) require all new consumer units to be made from non-combustible (metal) materials with full RCD protection.

Our NAPIT registered electricians will assess your current installation, recommend the appropriate consumer unit for your property, and complete the upgrade in a single day. The work includes full testing and an Electrical Installation Certificate for Building Control and insurance purposes.

Common Questions

You should consider an upgrade if you have: rewirable fuses instead of MCBs, no RCD protection, a plastic consumer unit, frequent tripping, or if your EICR has identified issues. If your fuse board is more than 15-20 years old, it's likely worth upgrading for safety and compliance.
Most domestic consumer unit upgrades take 4-6 hours, completed in a single day. The power will be off during the changeover (typically 2-4 hours), so we recommend scheduling at a convenient time.
Not necessarily. A consumer unit upgrade can be done independently if the existing wiring is in reasonable condition. If our testing reveals issues with the wiring, we'll let you know and discuss options. In some cases, a partial rewire of specific circuits may be recommended.
An RCD protects a group of circuits - if it trips, multiple circuits lose power. An RCBO combines an MCB and RCD in one unit, protecting individual circuits independently. RCBO boards are more convenient (one trip only affects one circuit) but cost more. We'll advise on which is right for your property.
Yes, consumer unit replacement is notifiable electrical work under Building Regulations Part P. As NAPIT registered electricians, we self-certify the work and notify Building Control on your behalf. You'll receive an Electrical Installation Certificate.
Costs depend on the size of the board needed, number of circuits, and any additional work required. Contact us for a free assessment and fixed-price quote. We'll explain exactly what's included with no hidden fees.
