786 Electricals: Your Trusted, Fully Compliant NAPIT Experts Since 2010

Welcome to 786 Electricals, the leading specialists for certified and safe consumer unit replacement across Leicester and Leicestershire.

Since 2010, we have been committed to domestic electrical safety, holding continuous registration with NAPIT (National Association of Professional Inspectors and Testers), giving you complete confidence in our competence and compliance. Our NAPIT Membership Number is 14212.

We are proud to offer a superior standard of installation with 100% transparent pricing. We don't just replace your fuse board; we upgrade your home's safety to the highest modern standard.

All-Inclusive, Fixed-Price Consumer Unit Package from Just £650

The average cost for a standard, fully certified consumer unit replacement in a typical Leicester home starts from £650. This is a comprehensive, fixed price for peace of mind, with absolutely no hidden costs for the essential safety components.

Your £650+ Price Includes the Gold Standard in Safety:

• New Metal Consumer Unit: A fire-rated, steel enclosure that fully complies with the 18th Edition Wiring Regulations (BS 7671, Amendment 3).
• Superior RCBO Protection: Supply and installation of Type A RCBOs for every single circuit. This is the ultimate protection, preventing the entire board from tripping if one appliance faults, and handling complex modern electrical loads (EV chargers, solar, smart tech).
• Essential Surge Protection: A dedicated Surge Protection Device (SPD) is included as standard to protect all your expensive electronics (TVs, PCs, kitchen appliances) from power spikes and lightning strikes.
• Full Certification: We issue an official Electrical Installation Certificate (EIC) immediately upon successful testing.
• Legal Compliance: We handle the necessary Building Control Notification (Part P) with your local authority on your behalf.

Crucial Note on Pricing: The £650 starting price covers a standard replacement on a functional existing system (typically 6-10 circuits). If a pre-installation check reveals non-compliant, dangerous existing wiring (e.g., inadequate earthing or bonding), we will provide a clear, detailed, and fixed quote for the minimal remedial work before proceeding.

Understanding Your Quote: What Determines the Final Cost?

While our standard consumer unit replacement starts from £650, the final, fixed quote for your Leicester home depends on the existing condition of your electrical system. As NAPIT registered electricians, we are legally obliged to ensure the entire system is safe and compliant before issuing a certificate for the new consumer unit.

Here are the key factors that may affect the total cost beyond the standard replacement package:

1. Condition of Existing Wiring and Cable Length

A straight replacement is fastest and cheapest. However, older installations often present challenges that require remedial work:

• Short Cables: If existing circuit cables are too short to safely reach the new consumer unit terminals, they must be safely re-extended within a suitable enclosure. This adds time and materials.
• Cable Reorganisation: Consumer units mounted in tight spaces, such as under-stairs cupboards or small cabinets, often require cables to be reorganised, labelled, and tidied before the new board can be safely installed.

2. Earthing and Main Protective Bonding Requirements

For certification, we must confirm that your property has compliant main earthing and bonding to incoming services (gas and water pipes). This is a critical safety check:

• Missing or Inadequate Bonding: If the required earthing or bonding cables are missing or undersized, they must be correctly installed to meet the current 18th Edition standards. This is non-negotiable for system safety and certification.

3. Supply and Installation Accessibility

The location and surrounding conditions of the existing fuse board significantly impact installation time:

• Poor Accessibility: Consumer units should be easily accessible. Units fitted in cramped locations—such as deep within cupboards, low down behind obstacles, or in positions requiring the electrician to kneel, bend, or work in restricted space—increase the time and difficulty of the installation, which must be reflected in the quote.
• Reorganisation Due to Property Layout: If the property has undergone major renovations or reorganisation over time, the existing supply configuration may require minor adjustments to ensure the new board is mounted safely and correctly.

4. Incoming Supply and Isolation

We must assess the condition of the main supply components:

• Supply Cable Suitability: We check if the existing main supply cables from the meter are adequately sized and in good condition to handle the demands of the new consumer unit.
• Main Isolation: The property must have a safe and functioning main isolation switch (either at the meter or on the existing board). If a dedicated, safe method of isolation is not present, we will need to install one to ensure future maintenance can be carried out safely.



Customer Safety Questions Answered: Why Our Upgrade is Better

Why Choose Type A RCBOs Over Standard Protection?

Most budget quotes use cheaper, standard RCD protection for groups of circuits. We only use Type A RCBOs. This distinction is vital for a Leicester home: it provides individual circuit protection and is specifically designed to work correctly with modern, sensitive equipment that can generate small DC currents, such as heat pumps, EV chargers, and smart lighting systems. This prevents nuisance tripping and protects your technology.

Is a Surge Protection Device (SPD) a Legal Requirement?

Since the 18th Edition was introduced, an SPD has become a critical requirement for safety in many installations, particularly those connected to the modern power grid. It is your home's first line of defence against electrical damage caused by external power issues. We include it as a non-negotiable part of our package, ensuring your home is future-proofed against costly damage.

What is the Difference Between an EIC and Building Control Notification?

• Electrical Installation Certificate (EIC): This is the technical document we issue, confirming that the new consumer unit itself has been designed, installed, and tested correctly according to BS 7671.
• Building Control Notification (Part P): This is the legal requirement. As a NAPIT Registered Installer (14212), we are legally entitled to self-certify the work, notifying your local council that the work meets the Building Regulations. You receive a separate certificate from NAPIT/Building Control.

How Long Will My Power Be Off During the Replacement?

For most standard homes in Leicester, the power is only off for approximately 4-6 hours while the physical changeover and final testing are carried out. We aim for minimal disruption and will always give you a clear timeline before we begin.
