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

  1. Does the benefit cover home, workplace and public charging, or only some of those?
  2. How many public charge points are accessible, and on which networks?
  3. What happens for an employee with no off-street parking?
  4. Does it work with our existing lease provider, or must we change?

Compliance and evidence

  1. How is home charging cost separated from household electricity?
  2. What evidence is retained per charging session, and for how long?
  3. How is business mileage reimbursement calculated, and is it based on actual cost or a flat rate?
  4. What happens at a HMRC enquiry: what can you produce, and how quickly?
  5. How is the National Minimum Wage floor checked each month?

Payroll and administration

  1. What exactly does payroll receive each month, and in what format?
  2. How are joiners, leavers and mid-month changes handled?
  3. How is the monthly reconciliation between deductions and charging cost done?

Employees

  1. How long does employee onboarding take, realistically?
  2. What support exists when a public charging session fails?

Commercials

  1. 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.
