Workplace chargers: the £500-a-socket grant, the recruitment perk, and the trick to charging staff fairly

There's a £500-per-socket grant. There's a recruitment story. And there's a colleague called Dave who unplugs other people's cars at 11am to swap in. We're going to fix all three.

Energy Partners · 22 June 2026 · 7 min read

The Workplace Charging Scheme was uplifted on 1 April 2026 to £500 per socket, capped at 40 sockets per applicant, with a 75% cost cap and a maximum grant of £20,000 per site. Combined with salary sacrifice on an EV at the 3% Benefit-in-Kind rate for 2026/27, a £45,000-earning employee on a Tesla Model 3 saves roughly £3,800 a year in income tax and National Insurance. Workplace charging now ranks in the top ten office amenity preferences for under-30s in 2024 graduate-recruitment surveys. Free money from the government, retention value, recruitment value, and tax-efficient salary sacrifice all stacked on top of each other. So why are most workplaces still arguing about it in the car park? Because someone called Dave keeps unplugging Sarah's car at 11am to swap in. The villain in this post is the car-park politics of an under-specified workplace charging policy.

We'll get to Dave. First the grant maths.

The WCS, in numbers that matter

The Workplace Charging Scheme is a voucher-based grant administered by OZEV. The 2026 mechanics:

A worked example of the cap interaction: on a 4-socket install costing £4,800 (an unusually tight quote), 4 × £500 = £2,000, but 75% of £4,800 is £3,600 — so the grant is capped at the lower number, £2,000. On a 40-socket install costing £100,000, the grant maxes at £20,000, which is 20% of cost — well under the 75% cap. The 75% cap mostly bites at the bottom end, not the top.

You can also stack WCS with 100% first-year capital allowances on the chargepoint capex. At 25% corporation tax, that's another quarter back through your tax bill. The number of finance directors who have signed off a WCS install and forgotten to claim the FYA is depressing.

The second lever: salary sacrifice and the 3% BIK rate

EVs as company cars are currently taxed at one of the lowest Benefit-in-Kind rates in the UK system. For 2026/27, BIK on a fully electric company car is 3%. (For context, a comparable diesel is in the 30%+ region.) Add a salary-sacrifice arrangement on top and the maths gets genuinely silly.

Example: A 40-year-old employee earning £45,000 wants a Tesla Model 3 on a salary-sacrifice scheme through their employer. The lease cost is, say, £550/month gross. Sacrificed pre-tax, the cost to the employee is:

Versus paying for an equivalent car out of post-tax salary, the saving is roughly £190/month, or £2,280/year for the employee. The employer also saves employer's NI on the sacrificed salary — typically £70–£90/month, £840–£1,080/year per scheme participant. On a 20-employee scheme that's £17,000–£22,000 a year of NI saving back to the business.

The 3% BIK rate is scheduled to step up in future tax years per HMRC's published tables — small rises, but rises. The tax efficiency is best now and tapers gradually. Schemes set up in 2026 lock in the current band for the duration of the lease.

Combine: WCS-funded workplace chargers + salary-sacrifice EV scheme = a benefit package that costs the business comparatively little, costs the employee nothing in post-tax terms, and ranks above gym membership in graduate-survey amenity preferences.

The recruitment story, because it's load-bearing

The 2024 graduate-recruitment surveys from a number of major UK firms have started ranking "workplace EV charging" inside the top ten office amenity preferences for under-30 candidates. It's behind ergonomic desk setup, decent coffee and natural light. It's ahead of free fruit, fancy break rooms and "social events".

This matters because:

The argument that workplace charging is an "operational expense" misses the lever. It's a recruitment and retention tool with an operational expense attached. Costed against turnover savings on even one or two roles a year, the install is profitable before you turn the chargers on.

Now to Dave: the three policies that stop the car-park civil war

The reason most workplaces under-deploy charging isn't budget. It's the well-founded fear that the moment you put six chargers in for 80 employees, you'll spend the next two years arbitrating disputes between Dave (who arrives at 7am, plugs in, and stays plugged in until 6pm) and Sarah (who arrives at 9.30am, needs to leave at 12 for a school run with 8% battery, and can't get to a socket).

The solution is policy, not more sockets. Three policies, all easy to implement on most modern back-office platforms, all of which stop the fights before they start.

Policy 1: Booking-system access. Employees book a slot via a calendar or app — typically a 4-hour block. The charger only authorises charge against the booked plate or RFID card. No booking, no charge. No turning up at 7am to camp on a socket. Most OCPP-compliant back-office platforms support this natively. Adopt it. It's the single biggest reduction in car-park politics.

Policy 2: Rotation rules. Caps and fairness. Maximum 8 hours per day per employee. Maximum 3 sessions per week per employee. If you have more EV-driving staff than sockets — and you will, by year two — these caps spread access automatically. They also gently nudge staff toward home-charging for routine commutes and workplace-charging for top-ups or longer journeys, which is the right behaviour.

Policy 3: Pay-per-kWh staff billing. The mistake almost every workplace makes is free charging. Free is a queue magnet. It also creates a taxable benefit-in-kind problem if not managed correctly — though current HMRC guidance specifically exempts workplace charging from BIK on employee-owned EVs, that exemption depends on the charging being at the workplace, available to all eligible staff, and not delivered in lieu of salary. Free is also bad behaviour design. Charge staff something nominal — 8–12p/kWh covers the cost of supply, doesn't make the benefit unattractive, and immediately ends Dave's all-day plug-in habit. The back-office handles billing, deducts via expenses or payroll, and the queue empties itself.

Adopt those three and the chargers stop being a flashpoint and start being a benefit, which is what they were meant to be.

A worked example — a 20-socket office install

Site: 120-employee office, semi-urban South East. EV adoption among staff currently 25%, projected to hit 50% by 2028. Brief: 20-socket workplace install (10 × 22kW twins).

The quote:

Grants applied:

Salary-sacrifice value (run independently):

The chargers cost the business £20,000 net in year one. The salary-sacrifice scheme they enable returns £7,200 to the business in NI savings annually, before counting any retention effect. Payback on the chargers from the NI saving alone is under three years. The retention value is on top. The recruitment value is on top of that.

What to ask before you sign

  1. "Are the chargers and your business on the current OZEV-approved WCS lists?"
  2. "Does the back-office platform support booking, rotation rules, and pay-per-kWh billing as standard?"
  3. "Is the kit OCPP-certified, and at which version?"
  4. "What's the smart-charging behaviour — will the units load-balance across the supply automatically?"
  5. "Do you handle the WCS voucher redemption, or do I?"
  6. "What's the warranty length and who honours it if you change ownership?"

The short version

WCS pays £500/socket from 1 April 2026, up to £20,000 per site. Capital allowances stack. Salary sacrifice on a 3% BIK EV saves a £45k earner roughly £3,800/year and the employer roughly £900/year per scheme participant in NI. Adopt booking, rotation and pay-per-kWh billing from day one — those three policies prevent every car-park fight you're worried about. Done well, the chargers are a recruitment, retention and tax-efficiency tool with a small operational expense attached.
