Consumer Unit Upgrades Explained

Consumer Unit Upgrades Explained: Do You Need a New Fuse Board in Reading?

 

Your consumer unit (also known as a fuse board) is the heart of your home’s electrical system. It controls and protects all electrical circuits, helping to prevent electric shocks, fires and serious faults.

Many homes across Reading, Tilehurst, Caversham, Earley, Woodley and Lower Earley still rely on outdated fuse boards that no longer meet modern safety standards. If your property hasn’t had an electrical upgrade in recent years, a consumer unit replacement may be essential.

This guide explains when a fuse board upgrade is needed, the benefits of upgrading, and what Reading homeowners should expect in 2025.

 

 
What Is a Consumer Unit?

A consumer unit distributes electricity safely around your home and includes protective devices that shut off power when a fault is detected.

Modern consumer units typically include:

 

    • RCDs (Residual Current Devices)

    • RCBOs (individual circuit protection)

    • Surge Protection Devices (SPDs)

Older fuse boards often lack these protections, increasing the risk of electrical accidents.

 

 
Common Signs You Need a Fuse Board Upgrade

If you live in an older Reading property, particularly in areas such as Caversham Heights, Tilehurst or central Reading, look out for these warning signs:

 

    • Old-style fuse wire or ceramic fuses

    • No RCD protection

    • Frequent tripping of circuits

    • Burning smells or buzzing sounds

    • Scorch marks around the fuse board

    • Limited capacity for modern appliances

    • An electrician has advised an upgrade during an EICR

If your fuse board is over 20–30 years old, it’s likely outdated.

 

 
Why Fuse Board Upgrades Are So Important in Reading Homes

1. Improved Electrical Safety

Modern consumer units dramatically reduce the risk of:

 

    • Electric shock

    • Electrical fires

    • Appliance damage

RCDs and RCBOs cut power instantly when a fault is detected.

 

 
2. Compliance With Current Regulations

While it’s not illegal to have an older fuse board, any new electrical work must meet current standards. Upgrading ensures compliance with BS 7671 wiring regulations.

This is especially important for:

 

    • Landlords

    • Home sellers

    • Renovation projects

    • Home extensions

 

 
3. Supports Modern Living

Many Reading homes now use:

 

    • EV chargers

    • Electric showers

    • Induction hobs

    • Home offices

    • Smart home systems

Older fuse boards simply weren’t designed to handle today’s electrical demand.

 

 
4. Better Reliability & Fewer Power Trips

Modern boards isolate faults to individual circuits, meaning:

 

    • One issue won’t shut off the entire house

    • Less nuisance tripping

    • Easier fault finding

How Much Does a Consumer Unit Upgrade Cost in Reading? (2025)

Typical costs in Reading include:

 

    • £450 – £900+, depending on:

       

        • Number of circuits

        • Type of consumer unit

        • Property condition

        • Any additional remedial work

This price usually includes:

 

    • Supply and installation

    • Testing and certification

    • Building Control notification

 
Will a Fuse Board Upgrade Cause Disruption?

Most upgrades are completed within one working day. Power will need to be switched off during installation, but disruption is minimal when carried out by an experienced electrician.

 

 
Do Landlords in Reading Need Fuse Board Upgrades?

Landlords must ensure electrical systems are safe. If an EICR highlights a fuse board as unsafe or non-compliant, an upgrade is usually required.

Failing to address issues can lead to:

 

    • Fines

    • Invalid insurance

    • Legal risks

 
Final Thoughts

A consumer unit upgrade is one of the most important electrical improvements you can make to your Reading home. It improves safety, supports modern electrical usage and helps ensure compliance with current regulations.

If your fuse board is outdated or you’re planning renovations, extensions or new electrical installations, upgrading your consumer unit is a smart and often essential step.
