Contents
If you are comparing providers, the differences are rarely in the headline saving. They are in coverage, evidence and administration. These are the questions worth asking.
Coverage
- Does the benefit cover home, workplace and public charging, or only some of those?
- How many public charge points are accessible, and on which networks?
- What happens for an employee with no off-street parking?
- Does it work with our existing lease provider, or must we change?
Compliance and evidence
- How is home charging cost separated from household electricity?
- What evidence is retained per charging session, and for how long?
- How is business mileage reimbursement calculated, and is it based on actual cost or a flat rate?
- What happens at a HMRC enquiry: what can you produce, and how quickly?
- How is the National Minimum Wage floor checked each month?
Payroll and administration
- What exactly does payroll receive each month, and in what format?
- How are joiners, leavers and mid-month changes handled?
- How is the monthly reconciliation between deductions and charging cost done?
Employees
- How long does employee onboarding take, realistically?
- What support exists when a public charging session fails?
Commercials
- How is the provider paid, and does the fee change with take-up?
How we answer them
The Charge Scheme covers home, workplace and public charging across 76,000+ UK charge points, bolts on to any existing car scheme, and produces a single monthly payroll figure per employee. For business mileage, Reimburse calculates HMRC-compliant reimbursement from actual per-driver charging cost, with the evidence trail behind it.
