Why Your Current Fuse Box Might Not Be Ready for an EV
Many older properties in the UK still rely on outdated rewireable fuse boxes or early-generation RCD boards that were never intended for the heavy, sustained load of an EV charger. A typical 7kW wallbox draws a significant amount of electricity for several hours at a time. If your existing board lacks modern protection, this can lead to overheating, potential fire hazards, and frequent nuisance tripping that disrupts your home's power. Upgrading your consumer unit ensures the system can handle this consistent demand without compromising the safety of your property.

Who We Are
Our EV-Specific Consumer Unit Solutions
When we perform an EV consumer unit upgrade, we install modern, non-combustible metal enclosures that meet the latest fire safety standards. We integrate essential protection, such as Surge Protection Devices (SPD), to shield your vehicle's sensitive onboard electronics and your home appliances from sudden voltage spikes. By utilising RCBOs rather than standard RCDs, we provide individual circuit protection, which means if one circuit trips, the rest of your home remains powered. We also ensure that specific earthing and load balancing requirements are met, keeping your setup compliant and reliable.

Answers to common questions about our Ev Consumer Unit Upgrades in Warrington
Do I definitely need a new fuse box to get an EV charger installed?
Not always, but very often. If your current board is full, lacks space for an SPD, or uses old-style fuses, an upgrade is usually the safest and most cost-effective way to move forward. We will check your current board during our survey and give you an honest appraisal.
How long does a consumer unit upgrade take?
Most domestic upgrades in Warrington take between 4 and 6 hours. Your power will need to be off for most of that time, so we recommend planning ahead for things like fridge-freezers and home working.
What is an RCBO and why do I need one for my EV?
An RCBO is a clever switch that combines two types of protection. It stops the circuit from drawing too much power (overload) and also detects if electricity is "leaking" where it shouldn't (earth leakage). For an EV charger, which uses a lot of power for a long time, having a dedicated RCBO is a vital safety layer.
Is surge protection really necessary?
Yes. Modern cars and home appliances are essentially computers. A power surge from the grid can fry the delicate circuits in your car's charging system. A Surge Protection Device (SPD) acts as a shield, diverting that excess energy safely to the ground.
Will you notify Building Control about the work?
Yes. Because changing a consumer unit is "notifiable work" under Part P regulations, we handle the notification to your local authority through NAPIT. You will receive an official certificate in the post a few weeks after we finish.
