What Is a Consumer Unit? 

A consumer unit, often referred to as a fuse board or fuse box, is the heart of your property's electrical system. 
 
It safely distributes electricity throughout your property while protecting each electrical circuit from faults or overloads. 
 
Modern consumer units include advanced safety features such as: 
 
Residual Current Devices (RCDs) 
Residual Current Breakers with Overcurrent Protection (RCBOs) 
Surge Protection Devices (SPDs) 
Modern circuit breakers 
Improved fault detection 
 
These features provide a much higher level of protection than many older fuse boards. 

When Should a Consumer Unit Be Replaced? 

Many older properties across Harlow and Essex still have electrical installations that no longer meet current safety standards. 
 
You should consider upgrading your consumer unit if: 
 
Your fuse board still uses rewireable fuses 
Your consumer unit is over 20 years old 
You're carrying out major renovation work 
You're extending your property 
An EICR has recommended an upgrade 
Your circuits trip regularly 
You want greater protection for your family or business 
You are installing an EV charger or other high-powered electrical equipment 
 
If you're unsure whether your current consumer unit needs replacing, we can carry out a professional inspection and provide honest advice.
