Upgrading your fusebox (also known as a consumer unit) is one of the most important electrical improvements you can make to your home or business. In a busy city like London, where many properties are old and electrical demands are constantly increasing, having a modern and safe fusebox is essential. Choosing the best fusebox upgrades service in London can feel overwhelming due to the number of electricians and companies available. This guide will help you understand what to look for, what questions to ask, and how to make the right decision with confidence.
Why Fusebox Upgrades Are Important
Before choosing a service, it’s important to understand why a fusebox upgrade matters.
Improved Electrical Safety
Older fuseboxes may not meet current UK electrical safety standards. Modern consumer units include RCDs and RCBOs, which protect against electric shocks, fires, and overloads.
Supports Modern Power Needs
With today’s increased use of appliances, EV chargers, and smart home systems, old fuseboxes struggle to cope. An upgraded fusebox ensures smooth and safe power distribution.
Compliance with UK Regulations
Fusebox upgrades must comply with BS 7671 (IET Wiring Regulations). A professional service ensures your property meets legal requirements.
Signs You Need a Fusebox Upgrade
Knowing when to upgrade helps you avoid emergencies.
- Frequent tripping of circuits
- Flickering or dimming lights
- Burning smells or buzzing sounds
- Old-style fusebox with ceramic fuses
- Recent home renovation or extension
- Installing EV chargers or high-power appliances
If you notice any of these, it’s time to look for professional fusebox upgrade services in London.

Certified electricians ensure work is completed safely and legally, and they can issue an Electrical Installation Certificate (EIC) after the upgrade.

London has a wide range of property types, from Victorian homes to modern apartments.
