Professional Consumer Unit Replacement & Fuse Box Upgrades in Leicester

Is your home still protected by an outdated fuse box? At 786 Electricals Limited, we specialize in upgrading Leicester properties to the highest modern safety standards. With over 18 years of experience and full NAPIT registration (No. 14212), we provide a service that prioritizes your family's safety over "quick swaps."


The Reality of "Cheap" £500 Quotes

We know that when you search for an electrician in Leicester, you may see prices as low as £400 or £500. While these prices look attractive, it is important to understand what is being left out.


A "budget" installation often skips the following essentials:

  • No RCBO Protection: They often install "Dual RCD" boards. If one circuit trips, half your house goes dark.
  • No SPD (Surge Protection): They leave your expensive TVs, computers, and appliances vulnerable to power surges.
  • No Cable Upgrades: They may skip the mandatory 25mm meter tail and 16mm earthing conductor upgrades required by law.
  • No Certification: Many low-cost installers are not registered or qualified to self-certify under Part P Building Regulations. They may not provide an Electrical Installation Certificate (EIC) or notify Building Control, which can lead to £5,000 fines or issues when you try to sell your home.


At 786 Electricals, our average consumer unit replacement is £750. This isn't just a "box swap"—it is a full-day, comprehensive safety upgrade.


What’s Included in Our £750 "Gold Standard" Package?

We believe in honest, straightforward business. Our fixed-price package includes everything needed for a 18th Edition compliant installation:

  • Premium Metal Consumer Unit: Fire-rated to contain any internal faults.
  • Individual RCBO Protection: Each circuit has its own protection. If a fault occurs, only that circuit trips—the rest of your home stays powered.
  • Surge Protection Device (SPD): Built-in protection for your home's electronics.
  • Main Tail & Earthing Upgrades: We include 25mm tails and 16mm earthing conductors as standard.
  • Full Day Installation: We don't rush. A proper job takes 8 hours to install, test, and verify every circuit.
  • Legal Certification: You receive your digital EIC immediately, and your official Building Control notification follows via post.


Choosing Your Path: Inspection vs. Direct Swap

Every home in Leicester is different. Depending on your budget and the age of your wiring (30, 40, or 60+ years), we offer two ways to proceed:

Path A: The Inspection-Led Approach (Recommended)

We perform a full Electrical Installation Condition Report (EICR) before the upgrade. This is the gold standard recommended by NAPIT. It identifies hidden faults in your old wiring that might cause a new, sensitive board to trip constantly.


Path B: The Direct Replacement (Interim Safety)

Many customers choose to go straight to the replacement to increase safety levels quickly, perhaps before a full renovation or to prepare for an EV Charger or Electric Cooker installation.


Note: We must test the system during installation. If we find dangerous defects, we will provide a separate estimate to fix them so we can safely and legally certify the work.

Why Local Homeowners Trust 786 Electricals Limited

  • Future-Proofing: We always allow for spare ways in the unit, making it easy for you to add garden offices, showers, or solar PV in the future.
  • Transparent Expertise: We don't hide behind jargon. We speak to you on your level, explaining exactly what we are doing and why.
  • Local Reliability: We aren't a national "middle-man" agency. We are local Leicester electricians with a reputation built over 18 years.

Frequently Asked Questions (FAQ)


How long will my power be off?

Expect the power to be off for the duration of the work (approx. 6–8 hours). We suggest shutting down computers and sensitive electronics before we arrive.


Why do I need a metal consumer unit?

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


Can you upgrade a small "garage" board?

Yes. Beware of companies that quote a low price only to find out it was for a 2-way garage unit. Our quotes are specific to your home's actual circuit count.


What happens if you find a fault?

Because modern RCBOs are very sensitive, they often "see" faults that old fuse boxes ignored. If we find a fault during our mandatory testing, we will explain it clearly and provide a fair estimate to repair it.
