Yes, you can separate EV charging from the rest of your home’s electricity — but a second utility meter is only one of three routes, and usually the most involved. A utility-installed second meter, an EV tariff read through a smart meter, and your charger’s own session records all produce a separate charging figure. For most homes the third option, which costs nothing, does the job; a second meter earns its place when a tariff or an employer requires utility-grade numbers.
Key Takeaways
- Three routes separate your charging figure: a utility second meter, a smart-meter EV tariff, or the charger’s own session records.
- A second meter is utility paperwork plus electrician work; the meter itself usually remains the utility’s property.
- A meter only measures — savings come from any EV tariff attached to it, not from the meter itself.
Why Drivers Ask for a Separate Meter
- Proof for an employer. If your company reimburses home charging for a company car, it wants a defensible kWh figure, not a guess.
- An EV-only rate. Some utilities offer a cheaper rate that applies only to the car, and need a way to measure the car on its own.
- A clean split. Landlords, tenants and housemates sharing one supply want charging separated from the household total.
- Records. A standalone total is useful for tax records, expenses and checking what driving costs you.
The Three Routes, Compared
| Route | Who sets it up | What you get | Watch out for |
|---|---|---|---|
| Second utility meter | Your utility, with a licensed electrician doing the panel-side work | A separate utility bill for the charger circuit only; the most formal evidence there is | Application process, possible service charges, and meter position and panel space must exist |
| EV tariff via smart meter | Your utility, using the smart meter already on your home | Charging priced or reported separately by time window, with no new hardware | Only offered by some utilities; separation is by time of use, not by device |
| The charger’s own records | You — smart chargers log energy per session in their app | A per-session and monthly kWh total, exportable for expenses | Figures come from the charger, not the utility; check what evidence your employer or landlord accepts |
What a Second Meter Actually Involves
The meter itself usually stays the utility’s property; what you arrange is everything around it. Expect an application to the utility, a licensed electrician to prepare the meter base and charger circuit, and an inspection where local rules require one. Costs vary by utility and by how much panel work your home needs, so get both quotes in writing before you commit — there is no standard price. One thing a second meter does not do is add capacity: it measures a circuit rather than enlarging your supply, so the charger still has to fit your panel. Our guide to how many kWh it takes to charge an EV shows the order of magnitude a meter would record each month.
When the Charger’s Own Numbers Are Enough
Most drivers who ask for a separate meter really need a separate number, and a smart charger already keeps one: energy per session, per day and per month, tied to an RFID card or app account so two drivers can be told apart. That is often enough for personal records and many employer schemes — but ask first, because some schemes specify utility-metered data. Where the point is a cheaper rate rather than evidence, look at time-based pricing first: our guide to smart charging and time-of-use tariffs shows how scheduling alone, on one ordinary meter, captures most of the saving.
Chargers That Keep Their Own Records
The EVDANCE EV-ACT3204PE 22 kW wallbox offers RFID and app control, so each session is recorded against a user — the practical route for a household or small site that wants charging separated without new metering. For shared or commercial sites, the EV-AC03201T dual-connector AC station runs OCPP 1.6J with RFID, the standard arrangement for per-user billing records.
Frequently Asked Questions
Does a separate meter make charging cheaper?
No. A meter only measures. What can lower the price is an EV tariff attached to that measurement, usually rewarding off-peak hours — and a time-of-use tariff on your existing meter may achieve much the same.
Can a sub-meter be fitted just on the charger circuit instead?
Yes — a privately fitted sub-meter, installed by a licensed electrician, gives a separate reading. Check first whether whoever needs the figure accepts a private sub-meter reading as evidence.
Will a second meter change my home’s main bill?
Your charging moves off it. The household meter then records everything except the car, and the charger circuit is billed on its own account or rate — which is exactly the clean split most people are asking for.
