Ofgem price cap guide for EV owners (UK, June 2026)
The price cap sets the rules for standard tariffs — but EV drivers can often do far better with an off-peak charging tariff. Here is how the two compare in 2026 and how to choose.
- What the cap does and does not cover for EV tariffs
- How cheap overnight charging changes the maths
- Compare EV-friendly tariffs by postcode — no obligation
The price cap is reviewed quarterly; the current level covers April–June 2026, with the next change from 1 July 2026. Figures are illustrative.
Fast answer: what the price cap means for EV drivers
The Ofgem price cap limits standard variable tariffs, but most dedicated EV tariffs are fixed or time-of-use products that sit outside it. For drivers who can charge overnight, an EV tariff with a low off-peak rate is usually far cheaper for charging than a capped single-rate tariff — in exchange for a higher peak rate.
Key takeaway: use the cap as a benchmark, not a target. If you can shift charging (and ideally other heavy use) into the off-peak window, compare EV tariffs on their off-peak and peak rates — the off-peak rate is where the savings come from.
Compare EV-friendly tariffs for your home
A postcode-based quote shows the EV and standard tariffs available to you, so you can see how much an off-peak charging rate could save against the capped alternative.
What we use to compare
- Postcode — region and standing charges.
- Annual usage — home plus EV charging kWh, or an estimate.
- Charging pattern — how much you can shift off-peak.
- Meter type — smart meter needed for most EV tariffs.
No pressure: a quote does not commit you to switching. Review off-peak and peak rates, standing charges and exit fees first.

Price cap vs dedicated EV tariffs
| Factor | Standard capped tariff | Dedicated EV tariff |
|---|---|---|
| Covered by price cap? | Yes (standard variable) | Usually no (fixed/time-of-use) |
| Off-peak rate | No special low rate | Low overnight rate for charging |
| Peak rate | Single capped rate | Higher than off-peak |
| Best for | Drivers who cannot charge overnight | Drivers who charge off-peak at home |
Charging cost example
Illustrative — charging a 60 kWh battery from low to full.
| Rate used | Cost of a full charge |
|---|---|
| EV off-peak (example 8p/kWh) | 0.08 × 60 ≈ £5 |
| Standard rate (example 25p/kWh) | 0.25 × 60 ≈ £15 |
Charging off-peak can cut the cost of a full charge by around two thirds in this illustration. Real figures depend on charging losses, battery size and how often you top up.
Pitfalls to avoid
Choosing an EV tariff you can’t use
If you can’t charge overnight, the higher peak rate may cost more than a standard capped tariff.
Comparing only the off-peak rate
Check the peak rate and standing charge too — your home’s daytime use still runs at the peak rate.
Forgetting you need a smart meter
Most EV tariffs require a working smart meter to bill the off-peak hours — arrange this before switching.
Ignoring fixed-term and exit fees
Many EV tariffs are fixed with exit fees. If you may move or switch, factor those in before committing.

FAQs
Does the price cap apply to EV tariffs?
It applies to standard variable tariffs. Most dedicated EV tariffs are fixed or time-of-use and sit outside the cap — use the cap as a value benchmark.
Are EV tariffs cheaper for charging?
For overnight chargers, usually much cheaper thanks to a low off-peak rate — in exchange for a higher peak rate.
How much to charge an EV at home in 2026?
Illustratively, a 60 kWh charge is about £5 at an example 8p/kWh off-peak rate vs roughly £15 at 25p/kWh standard. Real costs vary.
Will my EV tariff change when the cap updates?
A fixed EV tariff is locked for the term; a variable one can change at the quarterly review, next from 1 July 2026.
Do I need a smart meter for an EV tariff?
Usually yes — to bill the off-peak hours separately. Some EV tariffs also integrate with your charger or car.
