Workplace EV Charging Benefits: The Business Case in 2026
The workplace EV charging benefits that outlast the grant: tax-free charging for staff, low EV Benefit-in-Kind rates, capital allowances and the £500 WCS voucher.
By Evova · Published
The business case for workplace EV charging rests on three pillars the grant headlines tend to bury. First, HMRC treats employer-provided charging as a tax-free perk — no Benefit-in-Kind on the electricity or the equipment, provided a few conditions are met. Second, low company-car tax rates keep EV salary-sacrifice schemes attractive, and on-site charging is the perk that makes those schemes work day to day. Third, the Workplace Charging Scheme (WCS) pays up to £500 per socket and a 100% first-year capital allowance can relieve much of the rest. None of this guarantees a return — but if your staff already drive EVs, or you want them to, the numbers line up unusually well.
Free charging at work is not a taxable benefit — if you set it up right
Since 6 April 2018, employer-provided workplace charging has been exempt from income tax under section 237A of ITEPA 2003. The exemption covers the electricity, the cost of providing the charging facilities and any connected services — and it applies to employees charging their own private EVs, not just company cars.
Three conditions attach (HMRC Employment Income Manual EIM01035; last checked July 2026): charging must be at or near the workplace; it must be available to all your employees generally, or all those at that workplace; and the person charging must be the driver or a passenger. The “all employees” condition is the one that trips businesses up — chargers reserved for directors only can fall outside the exemption.
Two exclusions matter. The exemption does not apply if the charging itself is offered as part of a salary-sacrifice (optional remuneration) arrangement, and it does not cover charging at an employee’s home or reimbursing charging away from your premises. Company cars have separate reliefs — HMRC’s view is that electricity is not “fuel”, so workplace charging of a company car triggers no fuel benefit charge either. That’s the mechanism, not advice: how it lands in your payroll and P11D reporting is a question for your accountant.
Rising BiK rates haven’t killed EV salary sacrifice
Most salary-sacrifice tax advantages were removed in 2017, but cars with CO2 emissions of 75g/km or less were carved out — which in practice means EVs. An employee giving up salary for an EV is taxed on the car’s cash equivalent (a low percentage of list price), not the salary foregone, and the employer pays Class 1A National Insurance — 15% in 2025/26 — on that same low figure.
The zero-emission rate is rising, but from a very low base:
| Tax year | BiK rate (zero-emission cars) |
|---|---|
| 2025/26 | 3% |
| 2026/27 | 4% |
| 2027/28 | 5% |
| 2028/29 | 7% |
| 2029/30 | 9% |
Rates set to 2029/30 at Autumn Budget 2024 and left unchanged for zero-emission cars at the November 2025 Budget; last checked July 2026 — see GOV.UK.
Even at 9%, EVs sit far below petrol and diesel bands, so the arithmetic broadly survives. The structuring point to get right: keep workplace charging outside the sacrifice package. Offered separately to all staff, it stays tax-free; bundled into the optional remuneration arrangement, the s237A exemption is lost.
What it costs — and what the WCS and capital allowances remove
Spirit Energy’s published business-case research puts a typical commercial installation at £1,300 to £1,800 + VAT per chargepoint (last checked July 2026), depending on charger model, communications, unit count and the cabling or groundworks involved. The installer you choose will assess your supply and distribution board as part of the quote — long cable runs and limited spare capacity are the usual cost inflators.
The WCS covers 75% of purchase and installation costs, up to £500 per socket — up from £350 for installations completed before 1 April 2026 — across a maximum of 40 sockets per applicant over all sites. It is voucher-based: your business applies online via GOV.UK’s Find a Grant service, receives a voucher code by email, then has 180 days for an OZEV-authorised installer to complete the work and redeem it — our step-by-step claim guide covers the process. Businesses, charities and public-sector bodies qualify, provided you own the property or have landlord consent and have dedicated off-street parking for staff or fleet use. State-funded schools and colleges get an enhanced £2,000 per socket. Funding is confirmed until 31 March 2027, described by government as a final-year extension — so if the grant matters to your budget, timing matters too.
On top of the grant, a 100% first-year capital allowance applies to chargepoint expenditure, extended at the November 2025 Budget to 31 March 2027 (Corporation Tax) and 5 April 2027 (Income Tax). How the grant and the allowance interact in your accounts is accountant territory. Our grants hub tracks the current schemes, and you can find an OZEV-authorised installer or request a free quote when you’re ready to price the job.
Recruitment, retention and ESG — the honest version
We won’t quote a survey statistic on how many candidates demand workplace charging, because we haven’t verified one worth repeating. Qualitatively, the case is straightforward: for staff who already drive EVs — or who would take a salary-sacrifice car if charging were solved — on-site charging is a tangible daily benefit, in a way few perks are. It also removes the biggest practical objection to electrifying your own fleet, and gives sustainability reporting something concrete to point to rather than a pledge.
There’s a regulatory backdrop too. Since June 2022, new non-residential buildings in England with more than 10 parking spaces must include at least one chargepoint plus cable routes for one in five spaces under Approved Document S, with similar rules for major renovations. Existing buildings aren’t compelled — but the direction of travel is clear, and installing with the WCS is cheaper than installing without it. Our workplace charging hub covers the practical decisions, from socket counts to charger choice.
