The Spring Statement lands on 3 March 2026. Here's every tax, grant and mandate change already confirmed — plus three budget scenarios fleet managers should model now.
Be HMRC AER-compliant in 72 hours.
Set, calculate and audit EV mileage reimbursements at 7p (home) and 14p (public) — as outlined in HMRC Advisory Fuel Rates (Dec 2025) and the HMRC Employer Bulletin (Oct 2025). Supported by AFP guidance, Fleet News coverage and BVRLA policy notes.
Last reviewed: 15 Feb 2026.
Most UK fleets are now non-compliant with HMRC’s EV mileage rates
Since 1 September 2025, HMRC requires split Advisory Electricity Rates (AER). From 1 December 2025, the rates are 7 p/mile for home charging and 14 p/mile for public charging. Many employers still apply a single flat rate, creating reimbursement errors and non-compliance. HMRC now expects documented evidence that your reimbursement policy distinguishes between home and public charging.
- HMRC AER compliance
- EV mileage reimbursement policy
- Company car payroll evidence
Achieve full AER compliance and HMRC-ready documentation in just three business days
Your EV Decision Compass AER Compliance Pack delivers a CFO-ready reimbursement framework tailored to your fleet size and charging behaviour. Delivered in three working days, it includes:
- Fleet-specific reimbursement audit and HMRC compliance gap analysis
- Custom AER model with verified inputs (7p / 14p split)
- Formal compliance statement for payroll, audit, and HMRC inspection
- Expert review call plus an implementation checklist
Reduce reimbursement overspend, eliminate HMRC risk, and protect your payroll
Most fleets cut reimbursement overspend by 10–15%, recover thousands of pounds per 100 vehicles, and gain a defensible, audit-proof EV reimbursement policy. You’ll walk away with:
- A fully documented AER policy aligned with HMRC guidance
- Fleet-level savings benchmarks
- Ongoing access to the EVDC AER Calculator
Why it matters
Lower reimbursement costs & tighter control
Switching from a single flat rate to the official HMRC AER split (7 p/mile for home charging, 14 p/mile for public) aligns cost-per-mile with real energy use. Many fleets cut reimbursement overspend by 10–15 % while improving payroll fairness and transparency. (see industry coverage)
Payroll & audit readiness (HMRC evidence)
A documented EV mileage reimbursement policy that distinguishes between home and public charging gives payroll teams clear rules and provides HMRC-ready, audit-proof evidence for compliance reviews and internal audit. (see HMRC bulletin)
Faster processing, less admin
A standardised AER framework and calculator shorten approvals, reduce disputes, and speed up mileage reimbursement cycles — delivering cleaner data, fewer exceptions, and faster month-end close.
Driver trust & policy consistency
Clear 7p/14p rules improve driver understanding and ensure equal treatment across the fleet. Transparent policies reduce back-and-forth, protect employee relations, and build confidence in your reimbursement process. (see BVRLA note)
Data-led planning & measurable savings
Fleet-level benchmarks reveal where public charging costs exceed averages, where home or depot charging can expand, and how tariff optimisation turns compliance into measurable, ongoing savings.
Governance & risk reduction
Aligning your EV mileage policy with HMRC guidance strengthens corporate governance, reduces exposure to HMRC scrutiny, and provides board-level assurance on payroll and reimbursement controls.
