Electric Car Grant vs Salary Sacrifice: Which Saves UK Buyers More?

For employed buyers in 2026, salary sacrifice saves more money than the Electric Car Grant on almost every eligible model. An employee on £35,000 can save £2,000 to £3,500 per year through salary sacrifice on a typical sub-£30,000 EV. The Electric Car Grant saves a one-time £1,500 or £3,750. Over a three-year finance or lease period, salary sacrifice delivers three to five times the financial benefit. For self-employed, retired and private buyers, salary sacrifice is not available; the Electric Car Grant is the only government incentive they can access.

The good news: you do not have to choose. Employed buyers can sometimes benefit from both, since the Electric Car Grant reduces the car’s base cost, which reduces the lease cost, which reduces the monthly sacrifice.

How each scheme works

The Electric Car Grant

The Electric Car Grant (ECG) is a one-time purchase discount applied at the point of sale. OZEV places eligible cars in Band 1 (£3,750 off) or Band 2 (£1,500 off) based on sustainability criteria. The price cap is £37,000. You do not apply; the dealer deducts the grant automatically. Available to anyone buying an eligible new EV, including private buyers, businesses and employees.

Salary sacrifice

Salary sacrifice is an arrangement between an employee and their employer. The employee agrees to give up a portion of their gross salary in exchange for a lease on an electric car. Because the sacrifice comes from gross pay, before income tax and National Insurance are applied, the effective monthly cost is lower than the same car leased privately.

The Benefit in Kind (BIK) tax on the car is charged on the car’s P11D value at the prevailing rate. For electric cars, the BIK rate is 4% in 2026/27, rising to 5% in 2027/28 and gradually to 9% by 2029/30. This compares with rates of 25% to 37% for petrol and diesel equivalents, making the BIK charge on an EV minimal.

Head-to-head comparison

Factor	Electric Car Grant	Salary sacrifice
Availability	Anyone buying an eligible new EV	Employees only (employer must offer scheme)
Benefit type	One-time purchase discount	Ongoing monthly cost reduction
Maximum value	£3,750 (Band 1)	Varies; typically £2,000 to £4,000+ per year
Duration of benefit	Applied once at purchase	Throughout the lease (usually 2 to 4 years)
BIK tax applies?	No (you own the car or have a personal lease)	Yes (4% of P11D in 2026/27)
National Insurance saving?	No	Yes (employee NI saving on sacrificed amount)
Employer NI saving?	No	Up to 15% employer NI saving
Price cap	£37,000	No statutory cap (set by employer)
Can you combine with the other scheme?	Yes (grant reduces lease base for salary sacrifice)	Yes (see above)

Running the numbers: a real comparison

Scenario: A basic-rate taxpayer on £35,000 gross salary considers a Renault 4 (52kWh) with a list price of £27,000 before grant.

Option 1: Private purchase with Electric Car Grant

• List price: £27,000
• Band 1 grant: -£3,750
• Purchase price: £23,250
• PCP example (48 months, 10% deposit, 4.9% APR): approximately £290 to £320 per month

Option 2: Salary sacrifice (employer scheme)

• The employer leases the same Renault 4; grant reduces base cost
• Monthly sacrifice (gross): approximately £400
• Income tax saved (20%): -£80
• Employee NI saved (8% up to £50,270): -£32
• Net monthly cost to employee: approximately £288
• BIK tax (4% of £27,000 P11D ÷ 12 months × 20%): approximately £18 per month
• Total effective monthly cost: approximately £306

The salary sacrifice option is roughly comparable monthly in this example because the car is at the lower end of the price range. The difference becomes more pronounced for higher-earning employees and more expensive cars:

Higher-rate taxpayer (40%) on £60,000 salary, same car:

• Monthly sacrifice (gross): approximately £400
• Income tax saved (40%): -£160
• Employee NI saved (2% above £50,270 threshold): -£8
• Net monthly cost: approximately £232
• BIK tax (4% of £27,000 ÷ 12 × 40%): approximately £36
• Total effective monthly cost: approximately £268

A higher-rate taxpayer saves roughly £400 to £500 per year more than the basic-rate taxpayer through salary sacrifice, in addition to the employer’s NI savings of up to 15%.

Can you stack both?

In many cases, yes. Under a salary sacrifice scheme, the employer leases the car and the grant reduces the lease base cost, which reduces the monthly sacrifice. The grant benefit flows through to the employee via lower monthly payments. Not all salary sacrifice scheme providers and employers pass the full grant saving into the monthly cost, but many do. Ask your employer’s scheme provider explicitly whether the Electric Car Grant is applied to grant-eligible models.

If you are buying privately rather than through salary sacrifice, the grant applies directly to your purchase price.

Who should use salary sacrifice?

Salary sacrifice delivers the most benefit to:

1. Higher-rate taxpayers: the income tax saving is 40% of the sacrificed amount, versus 20% for basic-rate taxpayers. The NI saving is smaller above £50,270 (2% rather than 8%) but the income tax saving more than compensates.
2. Employees with access to a generous employer scheme: some employers cover insurance, servicing and tyres in the sacrifice package, making the effective saving even greater.
3. Employees who would lease rather than buy: if you were going to lease privately anyway, salary sacrifice is almost always cheaper on the same car.

Salary sacrifice is less appropriate for:

• Self-employed individuals (no salary to sacrifice)
• Employees close to National Minimum Wage (the sacrifice cannot take gross pay below NMW)
• People who want to own the car outright

Who should use the Electric Car Grant?

The Electric Car Grant is the right route for:

1. Private buyers who are not employed or whose employer does not offer salary sacrifice
2. Business owners purchasing a company car outright (the grant reduces the asset cost; claim alongside capital allowances)
3. Employees who want to own the car outright rather than lease through an employer
4. Anyone buying a Band 1 model: £3,750 is meaningful even without salary sacrifice, particularly on cars below £25,000

The myth: “salary sacrifice is too complicated”

For employees, salary sacrifice typically requires a single conversation with HR and a choice from the scheme’s vehicle list. The employer and scheme provider handle the lease, insurance (in most cases), servicing and administration. The monthly salary is simply lower, and the P11D value appears on your tax return for BIK calculation. Most major employers now offer schemes through providers such as The Electric Car Scheme, Octopus EV or Zenith. The complexity is on the employer side, not the employee side.

What about for vans?

The Plug-in Van Grant (PiVG, up to £5,000) is the equivalent of the ECG for commercial vehicles. There is no salary sacrifice equivalent for vans as used vehicles. Businesses purchasing electric vans can claim the PiVG and also benefit from 100% first-year allowance (full expensing) against corporation tax, which is a significant additional tax efficiency.

Bottom line

For employed UK buyers in 2026, salary sacrifice over a typical three-year period will save £5,000 to £12,000 more than the Electric Car Grant alone on the same car. The grant is a one-time discount; salary sacrifice is a sustained reduction in effective cost. If your employer offers a scheme and you were going to lease an EV anyway, salary sacrifice is almost certainly the better financial route.

But the grants are not either/or for employees: explore whether the grant reduces the lease base in your employer’s scheme, so you can benefit from both simultaneously.
