Why a consumer unit upgrade could be essential in 2026

If your lights trip regularly, circuits overload, or your property still has an old-style fuse board, your electrical system may not be providing the protection your home actually needs.

At Pailey Electrical Services, we regularly inspect Birmingham properties whereby outdated consumer units are no longer suitable for modern electrical demand. In many cases, the system technically “works” — but it doesn’t meet current safety expectations.

Your consumer unit is the safety control centre of your entire electrical installation. When a fault occurs, it is responsible for disconnecting power quickly enough to prevent electric shock, overheating, or fire.

If that protection isn’t fast or sensitive enough, the risk increases.

Why older boards are no longer enough

Electrical usage has increased dramatically over the last decade. Modern homes now run:

• High-powered ovens and induction hobs
• Electric showers
• Tumble dryers and washing machines
• Home office equipment
• EV chargers
• Outdoor power and garden lighting
• Smart home systems

Older fuse boards — particularly those with rewireable fuses or without RCD protection — were never designed for this level of demand. 

Without modern safety devices, faults may not disconnect quickly enough to prevent serious damage.

Across Birmingham and surrounding areas, common issues we identify include:

• No RCD protection
• Plastic consumer units
• Overloaded circuits
• Poor circuit separation
• No surge protection
• Deteriorating connections

Many homeowners are unaware that their fuse board would fail a modern safety inspection.

What a modern consumer unit provides

Upgrading your consumer unit with Pailey Electrical Services means your installation benefits from:

• Residual Current Devices (RCDs) for life-saving shock protection
• Miniature Circuit Breakers (MCBs) for precise fault isolation
• Surge Protection Devices (SPDs) to protect expensive electronics
• Fire-resistant metal enclosure
• Clear circuit identification
• Improved reliability and stability

A properly installed consumer unit significantly reduces fire risk and ensures compliance with current UK wiring regulations (BS 7671).

Signs you may need a consumer unit upgrade:

You should consider an upgrade if:

• Your fuse board contains rewireable fuses
• Your circuits trip frequently
• You are installing an EV charger
• You are renovating your kitchen
• You are adding an extension
• Your recent EICR recommended improvements
• Your consumer unit is over 15–20 years old

A consumer unit replacement is notifiable under Building Regulations and must be installed, tested and certified correctly.
