Professional Consumer Unit Replacement & Fuse Box Upgrades in Leicester

Is your home still protected by an outdated, plastic fuse box or old-fashioned rewireable fuses? At 786 Electricals Limited, we specialise in professional consumer unit replacements across Leicester and the wider Leicestershire area.


With over 18 years of experience and full NAPIT registration (No. 14212), we don't just "swap boxes." We provide a comprehensive safety upgrade that ensures your property meets the latest 18th Edition (Amendment 2) Wiring Regulations.


(Why Your Leicester Home May Need a Fuse Box Upgrade

Many homes in Leicester still rely on electrical technology from thirty or forty years ago. While these old boards might still "work," they lack the life-saving technology required for modern living—especially if you are planning to add an EV Charger or Electric Cooker.


Top 5 Signs You Need a Replacement:

  • Rewireable Fuses: If you have to fix a fuse with a piece of wire, your system is dangerously obsolete.

  • Plastic Enclosure: Older plastic boards are a fire risk. Current UK law mandates non-combustible metal-clad units.

  • No "Test" Button: This means you lack RCD protection, which is essential to prevent fatal electric shocks.
  • Frequent Tripping: If your fuses blow or switches trip often, your board is struggling with modern electrical loads.

  • Adding New Technology: Installing Solar Panels or home offices requires a modern board to handle the increased demand safely.


The Truth About "Cheap" £500 Quotes

We understand that price is important. When searching for an electrician in Leicester, you may see quotes as low as £400 or £500. It is vital to understand that a "budget" installation often omits critical safety features:

  • No RCBO Protection: Budget installers often use "Dual RCD" boards. If one circuit develops a fault, half your house (including your fridge and lights) goes dark.
  • No Surge Protection (SPD): These installers leave your expensive Smart TVs, computers, and appliances vulnerable to power surges.
  • Skipping Cable Upgrades: They may fail to upgrade your 25mm meter tails or 16mm earthing conductors, which is often a legal requirement.
  • Missing Certification: Unregistered installers cannot self-certify under Part P Building Regulations. This can lead to £5,000 fines or complications when you try to sell your home.

At 786 Electricals, our average consumer unit replacement is £750. This is a fixed-price, full-day investment in your home’s safety.


Our £750 "Gold Standard" Package

We provide a transparent, all-inclusive service. Our standard Leicestershire installation includes:

  • Fire-Rated Metal Consumer Unit: Fully compliant with the latest fire safety regulations.
  • Individual RCBO Protection: Every circuit has its own dedicated protection. If a fault occurs, only that circuit trips—the rest stays powered.
  • Integrated Surge Protection (SPD): Protects your home’s electronics from voltage spikes.
  • Main Tail & Earth Upgrades: We include 25mm tails and 16mm earthing conductors as standard.
  • Full Day of Testing: We spend 6–8 hours testing every circuit in your home to ensure total safety.
  • Legal Certification: You receive a digital Electrical Installation Certificate (EIC) immediately, and we notify Building Control on your behalf.


Choosing Your Upgrade Path

Depending on your property's age and your future plans, we offer two professional approaches:


Path A: The Inspection-Led Approach (Recommended)

We perform a full Electrical Installation Condition Report (EICR) before the upgrade. This identifies hidden faults in old wiring that might cause a new, sensitive board to trip. This is the "Gold Standard" for safety.


Path B: Direct Replacement (Safety-First)

Best for homeowners needing a rapid safety increase or those preparing for a specific upgrade like EV Charger Installation. We perform mandatory testing during the install to ensure the system is safe to energise.


Frequently Asked Questions (FAQ)


How long will my power be off?

For a standard home in Leicester, expect the power to be off for 6 to 8 hours. We recommend keeping your fridge/freezer closed during this time.


Why do I need a metal consumer unit?

Since the 18th Edition regulations, all new domestic consumer units must be made of non-combustible material (metal) to prevent the spread of fire.


What happens if you find a fault during the installation?

Modern RCBOs are very sensitive. If we find a pre-existing fault (like a neutral-to-earth leak), we will explain it clearly and provide a fair quote for the repair so we can safely certify your home.


Do I get a certificate after the work?

Absolutely. As a NAPIT-registered company, we provide a full EIC and handle the Building Control notification for you.
