Need a fuseboard upgrade in North London? If your property still has an old-style fusebox with rewirable fuses, it’s time for an upgrade. Our NAPIT-certified electricians in North London provide professional consumer unit replacements that bring your electrical system up to modern safety standards.
What is a Fuseboard Upgrade?
A fuseboard upgrade (also called consumer unit replacement) involves replacing your old electrical distribution board with a modern unit featuring:
• RCD protection (Residual Current Device) to prevent electric shocks
• MCBs (Miniature Circuit Breakers) instead of rewirable fuses
• AFDD protection (Arc Fault Detection Devices) for fire prevention
• Surge protection to protect appliances from power spikes
• Clear circuit labeling for easy identification
Old fusebox vs modern consumer unit:
Old Fusebox Modern Consumer Unit
Rewirable fuses MCBs (trip switches)
No RCD protection Full RCD protection
No arc fault detection AFDD protection
Ceramic/wooden casing Fire-resistant plastic
Manual fuse replacement Automatic circuit protection
When Does Your North London Property Need a Fuseboard Upgrade?
Age-Based Indicators
• Pre-1990s fusebox: Likely lacks RCD protection (upgrade recommended)
• Pre-1960s fusebox: Immediate replacement required
• Rewirable fuses: Outdated and unsafe (replace with MCBs)
• Wooden or ceramic casing: Fire hazard (modern units use fire-resistant materials)
Safety Warning Signs
Immediate upgrade required if you notice:
• Frequent fuse blowing
• Burning smell from fusebox
• Scorch marks or discoloration
• Loose or damaged components

Step 3: Installation
Power isolation: – Main supply isolated at meter – Property without power during work
Old fusebox removal: – Disconnect all circuits – Remove old consumer unit – Inspect cables and connections
New consumer unit installation: – Mount new consumer unit – Connect circuits to MCBs – Install RCD and surge protection – Label all circuits clearly
Step 4: Testing & Certification
Comprehensive testing includes:
• Insulation resistance testing
• Earth fault loop impedance testing
• RCD trip time testing
• Polarity checks
• Circuit continuity verification
Certification provided:
• Electrical Installation Certificate (EIC)

RCD Protection: Why It’s Essential
What is an RCD?
A Residual Current Device (RCD) detects electrical faults and cuts power within milliseconds, preventing:
• Electric shocks (potentially fatal)
• Electrical fires
• Appliance damage
Legal requirement:
Since 2008, all new electrical installations and consumer unit upgrades must include RCD protection for most circuits.
How RCDs save lives:
• Detect current leakage as small as 30mA
• Trip within 40 milliseconds
• Prevent electrocution from faulty appliances
Fuseboard Upgrades and EICR Compliance in North London
Many North London landlords discover fuseboard upgrades are required following EICR inspections.
Common EICR failures requiring fuseboard upgrades:
C1 Defects (Danger Present)
• Exposed live parts in fusebox
• Missing or damaged RCD
• Severely deteriorated components
C2 Defects (Potentially Dangerous)
• Lack of RCD protection
• Outdated fusebox lacking modern safety features
• Insufficient circuit protection
• Overloaded circuits
Landlord timeline:
- EICR identifies fuseboard defects
- C1 defects require immediate action
- C2 defects should be resolved within 28 days
- Fuseboard upgrade scheduled
- Retest and updated EICR issued
Our landlord service:
• Fast scheduling (often within 7 days)
• Tenant-friendly installation times
• Clear communication throughout
• Updated EICR provided post-upgrade
Fuseboard Upgrades for EV Charger Installation
Planning to install an EV charger at your North London property? Most require fuseboard upgrades first.
Why EV chargers need modern fuseboards:
• High power demand: 7kW chargers draw significant current
• RCD protection required: Legal requirement for EV installations
• Circuit capacity: Older fuseboards lack spare capacity
• Safety compliance: BS 7671 regulations mandate proper protection
Combined EV charger & fuseboard upgrade:
• Fuseboard upgrade: From £970 + VAT
• EV charger installation: From £800 + VAT
• Combined package: From £1,500 + VAT
• Timeline: Completed same day

Frequently Asked Questions
Q: Can I upgrade my fuseboard myself?
A: No. Fuseboard upgrades are notifiable work under Building Regulations Part P. They must be done by a certified electrician registered with NAPIT, NICEIC, or equivalent.
Q: Will I be without power all day?
A: Yes, typically for 6-8 hours during installation. We work efficiently to restore power as quickly as possible.
Q: Do all circuits need RCD protection?
A: Most circuits require RCD protection under current regulations. Some circuits (like fire alarms) may use RCBO protection instead.
Q: What’s the difference between RCD and RCBO?
A: An RCD protects multiple circuits. An RCBO (Residual Current Breaker with Overcurrent protection) combines RCD and MCB functions for individual circuit protection.
Q: How long does a new consumer unit last?
A: Modern consumer units typically last 25-30 years. However, we recommend EICR inspections every 5-10 years to verify ongoing safety.
Q: Can I add more circuits during fuseboard upgrade?
A: Yes. Fuseboard upgrades are the perfect time to add circuits for new appliances, EV chargers, or home extensions.
Q: Will fuseboard upgrade increase my North London property value?
A: Yes. Modern electrical systems are a major selling point and essential for landlord compliance.
