Can multiple electric cars earn ERE through one charge point?

Short answer: yes, in principle. ERE isn’t measured per car; it’s measured through the meter integrated into the charge point itself. As long as all the electricity passes through that one verifiable meter and you own the connection, the total number of kWh counts, regardless of which car happened to be charging at the time. This article explains what’s actually measured, what needs to stay verifiable, and which assumptions you should still confirm with your provider.

What ERE actually measures: kWh through the meter, not the car

The conditions for private individuals come down to three things: an integrated MID-certified meter inside the charge point, ownership of the connection, and verifiable charging data in kWh. None of these conditions mention the car doing the charging. The meter records the electricity passing through it, full stop. Nowhere in the sources we’ve checked is a distinction made between “kWh for car A” and “kWh for car B” - registration happens at the level of the metered charge point and the connection, not at vehicle level.

One charge point, two cars: what changes in practice

If two (or more) electric cars charge through the same integrated meter, the sum of all sessions simply counts. In practice this usually means a higher annual charging volume than with one car, and so a higher gross ERE value, all else being equal. Nothing in the sources we’ve checked suggests the scheme distinguishes based on which vehicle used the electricity: the tradable unit is grid electricity delivered through a qualifying connection, converted at the fixed statutory rate of 0.33269 ERE per kWh.

What this means for your estimated earnings

Our calculator and comparison table work from a single charging profile: annual mileage and consumption per 100 km for one car, with a reference volume of 4,000 kWh a year as the example. If you charge two cars through the same charge point, your actual annual volume is likely higher than that reference point. In that case, don’t rely on the default values - enter your own, combined annual volume instead, for example by running the calculator twice (once per car) and adding the results together, or by taking your total kWh directly from your charge point’s session export. That keeps the indication representative of your household rather than a single car.

What needs to stay verifiable

The core requirement is that every session through that one meter stays traceable and exportable: kWh, timestamp, and linked to the connection. If smart charging splits the load between two cars across two sockets on one integrated meter, that’s still technically a single metered charge point, and eligibility shouldn’t change in principle.

Adding a second, physically separate charge point - a second wallbox for the second car - is a different matter. That second unit is new hardware and must qualify independently: its own integrated MID meter and its own verifiable data. The first charge point’s eligibility doesn’t automatically transfer to the second.

Shared use of the same circuit

If the meter or connection is also used for something other than EV charging, general household consumption on the same circuit, for example, that can complicate the verifiability of the charging sessions specifically. This scenario isn’t worked through in detail in the sources we’ve checked, so it’s worth raising directly with your provider if your charge point isn’t on its own, separately metered circuit.

What isn’t publicly documented yet

A number of practical questions aren’t explicitly answered in the public sources we’ve checked. Raise these with your provider before assuming an answer:

• Does the provider require the licence plate or make/model of each car to be linked to sessions, and is that for their own reporting or does it affect the ERE calculation itself?
• Does a second car belonging to another household member or co-resident on the same meter and connection simply count, or do additional conditions apply about who must be the account holder?
• Is simultaneous charging of two cars (for example with load balancing) registered separately, or treated as one continuous, combined session?
• How is a second, physically separate charge point on the same property handled administratively: as an extension of the existing registration, or as a completely new sign-up?

Overview: what’s clear and what to confirm

Clear from the conditions	Still worth confirming with your provider
The meter in the charge point measures total kWh, not per vehicle	Whether licence-plate or vehicle linking is required for their reporting
Ownership of the connection is a condition, not ownership of the car	Whether a car belonging to another household member automatically counts
A second physical charge point is a separate registration	How simultaneous charging with load balancing is recorded

Business use and lease cars

If a lease car or company car is also charging alongside a private car on the same charge point, a separate layer enters the picture: who is authorised for the connection and the data, and who is entitled to claim the ERE. That situation deserves its own assessment per scenario (employer, leasing company, rental or homeowners’ association) and is beyond the scope of this article; see our knowledge base article on home-charging a lease car for the details.

Summary

Multiple electric cars on one integrated, MID-certified charge point can generally earn ERE together without issue: the meter counts kWh, not vehicles. Make sure every session stays verifiable and linked to the connection, be cautious with a second physical charge point (which counts separately), and raise the open questions about vehicle linking and shared use with your chosen provider before assuming everything works automatically.
