Workplace EV Charging Tax Exemption 2026/27: What's Actually Tax-Free

The exemption in plain terms

Since 2018, HMRC has treated electricity provided by an employer to charge an employee's own car — whether fully electric or a plug-in hybrid — as a tax-free benefit, provided two conditions are met: the charging facility is at or near the employer's premises, and it's available generally to employees rather than reserved for a select few. There's no income tax, no Class 1 National Insurance, and critically, no monetary cap on how much electricity can be provided this way, unlike many other workplace benefits that come with a limit.

This makes workplace charging one of the cleanest tax-free perks available, but it's easy to misunderstand where the line sits — it covers electricity delivered at work, not reimbursement for charging done anywhere else.

What is and isn't covered

The distinction that trips people up most often: it's the place of charging that matters for this particular exemption, not the ownership of the car.

Worked example: cash allowance vs tax-free charging (basic-rate taxpayer)

Suppose an employer wants to give employees the equivalent of £360 a year (£30/month) towards EV charging costs, and is deciding between paying it as a cash allowance or providing free workplace charging of equivalent value.

A basic-rate employee ends up roughly £100.80 worse off under the cash allowance route for the same underlying value, and the employer pays an extra £54 in employer National Insurance it wouldn't otherwise incur. Run your own numbers through

to see how a taxable allowance would affect your specific pay.

Worked example: higher-rate taxpayer

The gap widens for a higher-rate (40%) taxpayer earning above £50,270, where Class 1 employee NI drops to 2% above that threshold but income tax rises to 40%:

A higher-rate taxpayer loses over £150 of the £360 allowance to tax and NI if it's paid in cash, compared with keeping the full value under the workplace charging exemption.

Worked example: employer-side saving across a workforce

For an employer providing the equivalent of £360/year in charging value to 50 employees, choosing free workplace charging over a cash allowance avoids employer National Insurance entirely:

That £2,700 a year is a straightforward saving for the business simply by delivering the benefit as workplace electricity rather than payroll cash — on top of the employee-side tax and NI advantage shown above.

How this differs from a salary sacrifice EV scheme

It's worth being clear that workplace charging and salary sacrifice EV car schemes are governed by entirely different rules. In a salary sacrifice scheme, an employee gives up part of their gross salary in exchange for the use of a company car, and the car itself is then taxed as a company car benefit, valued and reported via P11D based on its list price and CO2/electric range banding. That's a different calculation entirely from the electricity-charging exemption discussed here — you could have a salary sacrifice EV and separately benefit from free workplace charging for it, with each governed by its own rule. If you're weighing up whether a salary sacrifice EV scheme makes sense for your circumstances, compare the effect on your payslip with

Practical takeaways for employees and employers

• Employees: if your employer offers workplace charging, use it — it's genuinely free of tax and NI with no cap, unlike almost any cash alternative.
• Don't assume a "charging allowance" is the same thing. If the benefit arrives as an amount on your payslip rather than electricity delivered at work, it's very likely taxable.
• Employers: providing charge points at the workplace, available generally to staff, is more tax-efficient for both sides than paying a cash top-up, and avoids the 15% employer National Insurance charge that a cash allowance would trigger.
• Keep the schemes separate in your head: workplace charging exemption vs salary sacrifice company car taxation are two different rulebooks, and mixing them up is the most common source of confusion.

Bottom line

If your workplace offers free EV charging, it's one of the few genuinely uncapped, entirely tax-free benefits still available in the UK system. A cash charging allowance sounds similar but is treated completely differently — taxed in full as earnings, with both employee and employer National Insurance applying.
