Consumer Unit & Fuse Box Services in London
Installation, Replacement, Inspection & Maintenance – Fully 18th Edition Compliant
The control center for your electrical system is now called a consumer unit, which is what your fuse box is. It keeps your property safe from overload, electric shock, and fire.
If your current fuse board is old, keeps tripping, or has failed an EICR, it might not be safe according to UK rules anymore.
We offer full consumer unit and fuse box services throughout London, including installation, inspection, maintenance, upgrades, and full replacement. All work is done by NICEIC-approved electricians who are also certified to BS 7671 (18th Edition Amendment 2).
Safe. Obedient. Certified by professionals.

Is Your Fuse Box Still Safe?
Many London properties still have old fuse boards fitted years ago. At the time, they were compliant. Today, electrical demand is much higher. You may need a replacement if:
- Your fuses are old and can be rewired.
- You have old rewireable fuses
- There is no RCD protection
- Your unit is plastic (pre-2016 type)
- You notice burning smells or buzzing
- Your EICR report shows C1 or C2 faults
Older systems were not designed for modern kitchens, EV chargers, high-load appliances, or HMO requirements.
If your system is over 20–25 years old, an upgrade is often the safest solution.

Fuse Box vs Consumer Unit – What’s the Difference?
Most people still say “fuse box”. The modern term is consumer unit.
Here is the simple difference:
Old Fuse Box | Modern Consumer Unit |
Uses fuse wire | Uses resettable circuit breakers |
Limited protection | RCD / RCBO protection |
Often plastic | Fire-rated metal enclosure |
Not surge protected | Surge Protection Device (SPD) |
Difficult fault isolation | Individual circuit protection |
Modern consumer units are designed to disconnect power instantly when a fault occurs, reducing the risk of electric shock or fire.

Frequently Asked Questions (FAQ)
Are old fuse boxes illegal in the UK?
Old fuse boxes are not automatically illegal, but they often do not meet current 18th Edition safety standards. If they lack RCD protection or proper earthing, upgrading to a modern consumer unit is strongly recommended for safety and compliance.
What is the difference between a fuse box and a consumer unit?
A fuse box is the older name for traditional fuse boards that use fuse wire for protection. A consumer unit is the modern version that uses circuit breakers and advanced safety devices to provide better protection.
Do I need an EICR before replacing my consumer unit?
An EICR is not always legally required before replacement, but it is strongly advised. It helps identify hidden wiring faults before a new consumer unit is installed.
Is surge protection mandatory in London?
Current wiring regulations require surge protection unless a formal risk assessment confirms it is not necessary. In most London properties, installing an SPD is recommended to protect appliances and sensitive electronics.
How long does consumer unit replacement take?
Most consumer unit replacements take between four and eight hours, depending on the number of circuits. The electricity supply will be temporarily disconnected during installation.
Can I stay in the property during installation?
Yes, you can usually remain in the property while the work is carried out. However, power will be switched off for several hours during the replacement process.
Will I receive a certificate after installation?
Yes, you will receive a full Electrical Installation Certificate upon completion. We also handle Building Control notification under Part P regulations.
Do I need to rewire my whole house to replace the fuse box?
In most cases, a full rewire is not required when replacing a fuse box. If any wiring fails safety testing, we will clearly explain what additional work may be needed.
How often should a consumer unit be replaced?
There is no fixed expiry date, but most consumer units have a lifespan of around 20 to 25 years. If your unit is outdated or fails inspection, replacement is advisable.
