Compare faster and slower public charging prices

Do not assume that faster public charging costs more or less than a slower option. Record current pre-start prices for both options under the same payment, membership, location and energy assumptions. Show no comparison when either observed input is missing, stale or outside the seven-day current-price limit.

Key facts and evidence

Across the UK, as at 12 August 2026, a faster-versus-slower public-charging price comparison needs two matching, current observations for the chosen payment and membership state. EV Evidence has no admitted operator price observations and assumes no direction or gap. A value older than seven days cannot be labelled current or drive a recommendation.

Office for Zero Emission Vehicles and Department for Transport: Public Charge Point Regulations 2023 guidance

Compare faster and slower UK public charging only from matching current observations, with no assumed price gap or recommendation.

Match the observations

For both options record the site or network scope, charging category shown by the source, payment channel, membership or subscription state, maximum p/kWh, timestamp, expected billed kWh and any separately stated third-party parking cost.

Apply the current-price gate

Call an observation current only for up to seven days and never beyond an earlier source expiry or displayed end time. Once stale, remove it from the difference, cost, saving, ranking, meta and recommendation outputs.

Compare one energy scenario

For each option, charging ceiling in pounds = observed maximum p/kWh × the same user-selected kWh ÷ 100. Add only matching separately stated costs, show assumptions beside the result and publish no winner when the inputs do not match.

What to do next

A price comparison does not verify availability, connector compatibility, charging performance or equipment condition.

Immediate action: Collect both observations with their timestamps before entering a comparison.

  • Stop if either observation is more than seven days old or lacks a timestamp.
  • Do not compare different payment channels, memberships or energy assumptions without labelling those differences.

Checks that stay with this vehicle

  1. Record each pre-start maximum p/kWh with point, channel, membership and timestamp.

    Two dated observations can be checked for matching assumptions and freshness.

    Either display is absent or the observations cannot be made comparable.

Professional hand-off

  • Ask the relevant operator to confirm an absent, unclear or channel-specific current price.
