HMRC fixes the new Advisory Electricity Rates
Updated on

🚨 Breaking News for UK Fleets 🚨

HMRC has just corrected its mistake on the new Advisory Electricity Rates (AER) for EV company cars.
👉 From 1 September:
Home charging stays at 8 ppm
Public charging rises to 14 ppm (not 12 ppm as first announced)
Why it matters for fleet managers:
More accurate reimbursement for drivers using public chargers
Clearer separation between home vs public charging costs
Flexibility: employers can still pay more if costs are higher (e.g. ultra-fast charging)
This correction is a win for transparency and a reminder of how fast policies are shifting.
