What's Involved in a Home EV Charger Installation?

As electric vehicles become increasingly popular across the UK, more homeowners are considering installing dedicated EV charging points at their properties. While the prospect of charging your electric vehicle at home offers unparalleled convenience and cost savings, many people wonder what exactly the installation process entails. From initial site surveys to final commissioning, here's your comprehensive guide to home EV charger installation.

The Initial Site Survey: Laying the Groundwork

Every successful EV charger installation begins with a thorough site survey conducted by qualified electricians. This crucial first step involves assessing several key factors that will determine the optimal installation approach:

Property Assessment

Our engineers evaluate your property's layout, identifying the most practical location for the charging unit. We consider factors such as proximity to your parking space, accessibility for cable routing, and protection from environmental elements. The ideal location balances convenience with safety, ensuring the charger is easily accessible while remaining protected from potential damage.

Electrical Infrastructure Review

During the survey, we examine your existing electrical setup, including the location of your consumer unit (fuse box), main incoming supply, and overall electrical capacity. This assessment helps us determine whether your current system can support an EV charger or if upgrades are necessary.

Future-Proofing Considerations

We also discuss your current and future EV charging needs. Are you planning to add a second electric vehicle? Do you anticipate needing faster charging capabilities? These conversations help us recommend the most suitable charger model and installation approach for your specific requirements.

Electrical Capacity Checks: Ensuring System Compatibility

One of the most critical aspects of EV charger installation is verifying your property's electrical capacity. Most UK homes have a single-phase 100A supply, which must accommodate all your household electrical demands plus the additional load of an EV charger.

Load Calculation Analysis

Our electricians perform detailed load calculations to ensure your electrical system can safely handle the additional demand. We assess your existing electrical appliances, heating systems, and any other high-power equipment to determine the available capacity for EV charging.

Smart Charger Benefits

Modern EV chargers incorporate smart technology that can dynamically manage power consumption. These intelligent systems can reduce charging rates during periods of high household electricity usage, ensuring you never exceed your property's electrical capacity while still achieving optimal charging performance.

Cable Routing: The Invisible Infrastructure

Proper cable routing is essential for both safety and aesthetics. Our installation approach prioritises neat, discreet cable runs that maintain your property's appearance while ensuring long-term reliability.

Surface Mounting vs. Concealed Routing

Depending on your property's construction and your preferences, we can route cables either surface-mounted in trunking or concealed within walls and voids. Surface mounting offers easier future maintenance, while concealed routing provides a cleaner aesthetic finish.

Safety Considerations

All cable routing follows strict electrical safety regulations, maintaining appropriate distances from water sources, gas pipes, and other utilities. We ensure cables are properly supported and protected against physical damage throughout their entire run.

Consumer Unit Upgrades: When They're Necessary

Many older UK properties require consumer unit upgrades to accommodate EV charger installation safely. Here's when an upgrade might be necessary:

Outdated Consumer Units

Properties with old-style fuse boxes or consumer units that lack RCD (Residual Current Device) protection will require upgrading to modern standards. Current regulations mandate dual RCD protection or RCBOs for EV charger circuits.

Insufficient Capacity

If your existing consumer unit has no available ways (spaces for additional circuits) or cannot handle the additional load, we'll recommend an upgrade to a larger unit with adequate capacity for both current and future needs.

Smart Integration

Modern consumer units can integrate with smart home systems and EV chargers, providing enhanced monitoring and control capabilities. Upgrading offers an opportunity to future-proof your electrical system.

DNO Notifications: Regulatory Compliance

Under UK regulations, all EV charger installations must be notified to the District Network Operator (DNO) – the company responsible for maintaining your local electricity network.

What is DNO Notification?

The DNO notification process informs your local network operator about the new electrical load being added to their system. This ensures the local grid can accommodate the increased demand and helps maintain network stability.

Installation Certification

As OZEV-approved installers, CRG Direct handles all DNO notifications on your behalf. We provide the necessary certification and ensure full compliance with current regulations, giving you peace of mind that your installation meets all legal requirements.

Installation Timeframes: What to Expect

The duration of an EV charger installation varies depending on several factors, but most standard installations follow this timeline:

Standard Installation (1-2 Days)

A typical straightforward installation takes one to two days, including:

• Site preparation and cable routing
• Consumer unit work (if required)
• Charger mounting and electrical connections
• Testing and commissioning
• Customer demonstration

Complex Installations (2-3 Days)

More challenging installations involving longer cable runs, consumer unit upgrades, or special architectural considerations may require additional time. We provide accurate timeframe estimates during the initial survey.
