EV Charger Installation: Do You Need a New EICR First?

A home EV charger, also called an Electric Vehicle Supply Equipment (EVSE) unit or wallbox, is a dedicated charging point installed at a property that allows an electric or plug-in hybrid vehicle to charge significantly faster than a standard three-pin socket.

There are two main types relevant to home installations:

Mode 3 Charge Point (AC Wallbox): This is the standard home charger. It delivers between 7kW and 22kW of power and is hardwired directly into your property's electrical installation. Most home installations use a 7kW single-phase unit, which charges the average EV battery from empty to full overnight.

Three-Pin Socket Charging (Mode 2): Charging from a standard 13-amp socket is technically possible but is generally considered unsafe for regular use — it draws sustained high current through a socket that is not designed for it, creating a genuine fire risk over time. Wallbox installation is always the recommended approach.

An EICR (Electrical Installation Condition Report) assesses whether your existing electrical installation — your wiring, consumer unit, earthing, and protective devices — is safe and in good enough condition to support additional load.

Installing an EV charger adds a significant and sustained new load to your electrical system. A 7kW charger draws around 30 amps on a dedicated circuit — equivalent to running several high-power appliances simultaneously and doing so for hours at a time. If your existing installation is already old, degraded, or inadequately protected, adding that load without assessment first can create serious risks.

This is why a reputable EV charger installer will always assess the condition of your electrical installation before proceeding — and in many cases will require a valid EICR before they will complete the installation.

There is no single regulation that states "you must have an EICR before installing an EV charger." However, several intersecting regulations create a strong de facto requirement in many circumstances. Here is what the rules actually say:

Part P of the Building Regulations

EV charger installation is notifiable electrical work under Part P of the Building Regulations (England and Wales). This means the work must either be carried out by a Part P registered installer (who self-certifies their own work) or submitted to your local Building Control authority for inspection and sign-off.

A Part P registered installer is required to inspect and test the existing installation as part of their work. If they identify existing defects that they would see in a prior EICR, they must either refuse to proceed or ensure those defects are addressed first.

BS 7671 — IET Wiring Regulations (18th Edition)

The 18th Edition Wiring Regulations (the standard that all UK electricians must work to) require that any new circuit added to an existing installation must have RCD (Residual Current Device) protection on its supply. This is a core safety requirement for EV charger circuits specifically.

If your consumer unit is old and does not have RCD protection (common in properties with older fuse boards), your installer will need to either upgrade the board or install a separate RCD-protected means of supply for the charger circuit. An EICR would identify this requirement before work starts.

OZEV Grant Requirements (For Landlords)

The EV chargepoint grant for landlords, administered through the Office for Zero Emission Vehicles (OZEV), provides up to £350 per chargepoint (and up to £500 per parking space for residential car parks) to help landlords install EV chargers at their rental properties.

To access this grant, the installation must be carried out by an OZEV-approved installer, and that installer must be satisfied that the property's electrical installation is safe enough to support the charger. In practice, most OZEV-approved installers will request a current EICR as part of their pre-installation assessment, especially for older properties.

While the need for an EICR before EV charger installation depends on the specific property and installer, there are several situations where you should treat it as a firm requirement:

Your Property Is Over 25 Years Old

Older properties are statistically far more likely to have electrical installations that fall short of current standards, outdated wiring, inadequate earthing, no RCD protection, or deteriorated components. No responsible installer will add a significant new load to an aging installation without first verifying its condition.

Your Consumer Unit Is an Older Fuse Board

Properties with older consumer units, those using rewirable fuses or early MCBs without RCD protection, will almost certainly need an upgrade before an EV charger circuit can be installed to current standards. An EICR will confirm this and specify the required upgrade.

You Are a Landlord

If you're installing an EV charger at a rental property, you already have a legal duty to hold a valid EICR under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020. If your current EICR has expired, or if you don't have one in place, you need to address that first, independently of the charger installation.

Adding new electrical circuits to a property without a valid EICR also creates a grey area around your ongoing compliance obligations, which could cause difficulties at your next inspection.

You Are Applying for the OZEV Grant

As noted above, most OZEV-approved installers require evidence of a satisfactory EICR before completing an installation under the grant scheme. Without one, your application can be delayed or refused.

Your Installer Requests One

Any reputable, qualified EV charger installer will tell you if they need to see an EICR before they proceed. If an installer is willing to fit a charger on any property without assessing the electrical installation first, that is a warning sign, not a convenience.

When Might You Not Need a New EICR?

If you already hold a current satisfactory EICR (issued within the last 5 years for a rental property, or more recently for a homeowner's property) and it has no outstanding C1 or C2 faults, your installer may be satisfied to proceed using that existing report.

Similarly, if your property is a new build with an Electrical Installation Certificate (EIC) confirming that the installation was built to current standards, a separate EICR is unlikely to be required.

In both cases, the final decision rests with the installing engineer. They are professionally and legally responsible for the safety of their work, so if they identify concerns about the existing installation during their own assessment, they can still request an EICR before proceeding.

This is a question worth taking seriously. If you allow an EV charger to be installed without a proper electrical assessment:

• Your home insurance may be invalidated. Most home insurance policies require that electrical work be carried out in accordance with current regulations. An installation that bypasses Part P notification or ignores known electrical defects could give your insurer grounds to reject a future claim, including a fire claim.
• Your charger warranty may be voided. EV charger manufacturers typically require installation by a certified installer working to current standards. Non-compliant installation voids the warranty.
• You face legal risk as a landlord. If a tenant is injured or a fire starts, and it is found that you had electrical defects that were not addressed, you face potentially serious civil and criminal liability.
• You may fail your next EICR. Any defects that existed before the charger was installed and any new issues created by an installation that was not carried out correctly will show up in your next EICR as C1 or C2 faults.

The most time and cost-efficient approach is to arrange both your EICR and your EV charger installation as a coordinated sequence:

Step 1: Book an EICR: Have a qualified electrician carry out an EICR on your property. This gives you a clear picture of your installation's current condition and identifies anything that needs to be addressed before the charger is installed.

Step 2: Address Any Remedial Work: If the EICR identifies C1 or C2 faults or if it flags that a consumer unit upgrade is required before a new circuit can be added, arrange for the remedial work to be completed first. In many cases, the electrician who carried out your EICR can carry out the remedial work at the same time.

Step 3: Book Your OZEV-Approved EV Charger Installer: With a clean EICR in hand, your chosen installer has everything they need to proceed quickly and confidently. If you're a landlord applying for the OZEV grant, the EICR documentation satisfies their pre-installation requirements.

Step 4: Retain All Documentation: Keep your EICR, the installation certificate for the charger, and any Part P building regulations compliance certificate together in your property records. As a landlord, these documents form part of your compliance file.

1. Can my EV charger installer carry out the EICR as well? Some electricians are qualified to carry out both the EICR and the EV charger installation. However, it is common and perfectly acceptable to use separate providers for each. What matters is that both are carried out by qualified, registered engineers.
2. How long does an EICR take? For a typical 3-bedroom property, an EICR inspection takes between 2 and 4 hours. Larger or more complex properties take longer. Results are usually available digitally within 24–48 hours.
3. Will my consumer unit need upgrading for an EV charger? It depends on your current setup. If your consumer unit is old, lacks RCD protection, or has insufficient spare ways for a new circuit, an upgrade may be recommended or required. Your EICR will make this clear before you commit to the charger installation.
4. Does the OZEV grant cover the cost of the EICR? No. The OZEV grant covers the cost of the chargepoint and its installation only. The EICR is a separate cost, but it is a necessary investment to ensure your installation is completed safely and without complications.
5. Can I install a home EV charger without planning permission? In most cases, domestic EV charger installation falls under permitted development rights and does not require planning permission. However, if your property is a listed building or in a conservation area, you should check with your local planning authority first.
