Fuse Box Replacements in London – Professional, Safe & Fully Compliant Services
If you live in London and your home still relies on an outdated fuse box, upgrading to a modern consumer unit is one of the most effective ways to improve electrical safety. A fuse box replacement not only ensures your property meets current UK electrical regulations, but also provides better protection against electrical faults, fire risks, and power outages.
In this guide, we’ll explain why London homeowners are switching to modern consumer units, how the replacement process works, and how to choose the right electrician for the job.
Why Replace Your Fuse Box?
Upgrading your fuse box is essential if your home still uses an old-style unit with rewirable fuses. Modern consumer units offer major safety and performance benefits, including:
✔ Enhanced Safety
Modern units include RCDs (Residual Current Devices) and RCBOs, which detect faults instantly and shut off the power before injury or fire can occur.
✔ Compliance With UK Regulations
To meet BS 7671 (18th Edition) wiring regulations, most properties need an updated consumer unit. A new fuse box ensures your electrical system is compliant—important for insurance, renting, and selling your home.
✔ Better Electrical Performance
With London households using more appliances than ever, upgraded consumer units handle higher demand more reliably.
✔ Increased Property Value
Electrical safety improvements can increase your home’s appeal to buyers and pass required inspections with ease.
Common Signs You Need a Fuse Box Replacement
You may need a new consumer unit if you notice:
Frequent tripping or power outages
A burning smell near the fuse box
Rewirable fuses (instead of modern switches)
No RCD protection
A fuse box with a wooden backboard
Lights flickering regularly
Hot or discoloured sockets
If your property in London is over 25–30 years old, an electrical inspection (EICR) is also recommended.
How Fuse Box Replacement Works
A professional London electrician will follow these steps:
Initial inspection & safety check
Isolating the power supply
Removing the old fuse box
Installing a modern metal consumer unit
Testing circuits & issuing certification
Notifying building control (Part P)
The job typically takes 3–6 hours, depending on the size of the property and the condition of the existing wiring.
How Much Does Fuse Box Replacement Cost in London?
Prices vary depending on the number of circuits, the type of consumer unit, and the property size. On average, London fuse box replacement costs:
Standard home: £450–£750
Larger properties with multiple circuits: £750–£1,200+
EICR (if required): £350–£650
Always choose a NICEIC or NAPIT-registered electrician to ensure proper certification.
Why Choose a Professional Electrician in London?
London properties—especially older homes or flats—often have complex electrical systems. Using a qualified electrician ensures:
Full compliance with UK safety standards
Certification for insurance and legal purposes
Expert installation with high-quality materials
Peace of mind knowing the job is done safely
Avoid DIY electrical work; it is unsafe and illegal for consumer unit installations in the UK.
