Overview
- Inspection firm EVCI Global tested hundreds of in‑service chargers and found 31.5% fell outside a ±2% accuracy band, with roughly 15% erring by more than 5%.
- In the most extreme case cited, a unit delivered 37% less electricity than shown, though some devices also under‑billed by recording less energy than supplied.
- EVCI Global has submitted the results to Parliament’s Transport Select Committee and urged mandatory, periodic verification similar to petrol forecourt checks.
- The Department for Transport says public charge points are expected to deliver what they display and notes most meters are regulated to be accurate within 2%.
- ChargeUK argues the issues appear isolated and highlights the complexity of measuring electricity, as wider cost pressures include high public tariffs, a tribunal ruling cutting VAT on public charging to 5%, and a pay‑per‑mile levy set for 2028.
