Why a Consumer Unit Upgrade Is More Than Just a Fuse Box Change

While that may look similar on the surface, a proper consumer unit upgrade involves far more than just replacing equipment.

Done correctly, it’s a safety upgrade, a performance improvement, and an opportunity to prepare your Devonshire home's electrical system for how your home is used today — and how it may be used in the future.

The Difference Between a Swap and an Upgrade

A basic replacement focuses on the board itself. A proper upgrade looks at the entire electrical system connected to it.

That includes:

• Assessing the existing installation
• Verifying earthing arrangements
• Measuring electrical load and demand
• Testing all connected circuits
• Designing the new consumer unit around real usage

Without this wider assessment, problems can be hidden behind a brand-new board.

Why Guesswork Isn’t Good Enough

Homes today use far more electricity than they did when many older consumer units were installed. Electric showers, induction hobs, EV chargers, home offices, and modern heating systems all add load.

Assuming everything will be “fine” without checking demand, circuit condition, and capacity can lead to:

• Nuisance tripping
• Limited scope for future upgrades
• Costly remedial work later

A consumer unit upgrade should remove limitations, not create new ones.

What a Proper Upgrade Gives You

When a consumer unit is upgraded as part of a full assessment:

• Protection devices are correctly selected
• Circuits are verified and tested
• The installation is certified and notified properly
• The system is designed to support future changes

This approach forms part of a structured upgrade process rather than a cosmetic change
