AER Compliance Pack — Delivered in 72 Hours

Be HMRC AER-compliant in 72 hours. Set, calculate and audit EV mileage reimbursements at 8p (home) and 14p (public) — aligned with HMRC and AFP guidance. Cut overpayments, reduce audit exposure, and build confidence in your reimbursement policy.

Why this matters

Since 1 September 2025, HMRC has split the Advisory Electricity Rate (AER) for electric vehicles into:

  • 8 p/mile — home charging
  • 14 p/mile — public charging

Most companies still apply a single rate, creating non-compliance and unnecessary cost. Fleet News, the AFP, and HMRC’s October 2025 Employer Bulletin have all highlighted this issue.

Example: if 70% of charging occurs at home, the fair weighted rate is 9.8 p/mile. Across 800,000 miles a year, that represents roughly £33,600 in savings while staying compliant.

Frequently asked questions

What does “AER-compliant” mean?
Being AER-compliant means your EV mileage reimbursement policy aligns with HMRC’s Advisory Electricity Rate guidance. Since September 2025, employers must distinguish 8p/mile for home charging and 14p/mile for public charging, and document how those rates are applied.
Why did HMRC introduce two EV rates?
The split reflects real-world energy costs: home electricity is typically cheaper than public charging. The rates aim to ensure fair, evidence-based reimbursements.
What if we keep using a single rate?
A single rate risks non-compliance and inaccurate payroll. Many fleets also overpay without noticing.
Do we need to collect charging receipts?
HMRC expects clear policy evidence showing how home vs public mileage is identified and reimbursed. You do not typically upload receipts, but you must be able to evidence your approach.
How fast will we be compliant?
Delivery is within 72 hours of booking. You receive a CFO-ready framework, calculator, and audit templates reviewed against the latest HMRC and industry guidance.
Does it cover cars and vans?
Yes. It is designed for battery-electric company cars and vans (not hybrids/PHEVs).
Is it suitable for smaller fleets?
Yes — it works for SMEs as well as larger teams up to ~200 vehicles.
Can AER rates change?
Yes. AER values are reviewed periodically. Your policy remains valid; update the numeric rates when HMRC revises them.
What do we actually receive?
• AER policy framework (home/public logic & wording)
• Reimbursement calculator + benchmarks
