Full Consumer Unit Upgrade Package – From £750

Our "Gold Standard" installation is designed for the 18th Edition (Amendment 3) regulations. We provide a comprehensive, fixed-price service for a typical Leicester home (6-10 circuits) with zero hidden costs for essential safety.


What’s Included for £750:

  • Fire-Rated Metal Enclosure: A non-combustible steel unit to prevent the spread of fire.
  • Superior Type A RCBO Protection: We protect every circuit individually. If one appliance faults, your whole house won’t go dark. This is vital for modern tech like heat pumps and smart lighting.
  • Essential Surge Protection (SPD): Included as standard to protect your TVs, PCs, and appliances from power spikes.
  • Full Certification: Immediate Electrical Installation Certificate (EIC) and Part P Building Control Notification handled by us.


The 786 Process: What Happens During Your Upgrade?

We believe in informing our customers. A typical replacement in Leicester takes 4–6 hours. Here is how we ensure your home is safe:

  1. Pre-Installation Check: We assess your existing wiring to ensure it can safely handle a modern high-speed board.
  2. Safe Isolation: We install a dedicated main isolation switch if one isn't present, ensuring future maintenance is safe.
  3. The Changeover: We swap your old fuse box for the metal RCBO unit, reorganising and labelling all cables.
  4. Rigorous Testing: Every circuit is tested to BS 7671 standards before we power back up.


Understanding Your Quote: Factors That Affect Cost

While our standard package starts at £750, we are legally obliged as NAPIT installers to ensure your entire system is compliant. Some factors that may require minimal remedial work include:

  • Earthing & Main Bonding: We must confirm your gas and water pipes are correctly earthed. If bonding is missing or undersized, it must be upgraded for your safety.
  • Cable Length & Access: Units in tight spaces (like under-stairs cupboards) or those with short cables may require safe re-extension and reorganisation.
  • Condition of Existing Wiring: If a pre-check reveals dangerous faults, we will provide a clear, fixed quote for repairs before proceeding.


Common Questions & Expert Advice

Why Type A RCBOs instead of standard RCDs?

Budget quotes often use "split-load" RCDs. We only use Type A RCBOs because they are specifically designed to handle the small DC currents generated by modern electronics, preventing "nuisance tripping."

Is a Surge Protection Device (SPD) really necessary?

Yes. It is your home’s first line of defence. In the modern power grid, power spikes are common; an SPD prevents these spikes from frying your expensive household technology.

What is the difference between an EIC and Part P?

  • EIC (Electrical Installation Certificate): The technical document proving the work was done correctly.
  • Part P: The legal notification to Leicester City Council. As NAPIT members, we self-certify this for you.

Additional Maintenance & Value

While we are on-site for a consumer unit upgrade, many customers find it worthwhile to clear their "to-do" list of smaller electrical jobs. Whether it’s a flickering light or a cracked socket, we can bundle these repairs for maximum efficiency.

Need us purely for maintenance? We offer Fixed-Price Service Slots:

  • 2-Hour Slot: £150 (£75/hr) – Perfect for 1-3 small tasks.
  • 4-Hour Slot: £300 (£75/hr) – Ideal for multiple room upgrades.
