Salary sacrifice electric car vs buying — it is the question every UK employee weighs up before committing to an EV. The answer almost always tilts toward salary sacrifice, but the gap varies depending on your tax band, the car’s list price and how you would otherwise fund the purchase. This guide puts real numbers on both routes for 2026/27 so you can decide with confidence.
How Salary Sacrifice Works (and Why EVs Are Exempt from OpRA)
Under a salary sacrifice arrangement your employer leases a brand-new electric car and provides it to you as a benefit. In return you give up a portion of your gross salary — before income tax and National Insurance are deducted. Because the exchange happens pre-tax, you immediately save on both.
Most salary sacrifice benefits lost their tax advantage in 2017 when HMRC introduced the Optional Remuneration Arrangements (OpRA) rules. However, ultra-low emission vehicles with CO2 emissions of 75 g/km or less were deliberately exempted. That means fully electric cars keep their full income-tax and NIC savings — you are only taxed on the benefit-in-kind value, not on the salary you gave up. For 2026/27 the BIK rate on a zero-emission car is just 4%, rising to 5% the following year and capped at 9% from 2029/30.
What Is Included in a Salary Sacrifice Package?
One of the biggest advantages over buying or leasing privately is that a salary sacrifice package is all-inclusive. A typical scheme bundles:
- Fully comprehensive insurance — no need to shop around or pay separately
- Routine maintenance and servicing
- Tyre replacement due to normal wear
- Breakdown cover
- Road tax (VED)
When you compare monthly costs you therefore need to add insurance, servicing and VED to a PCP or HP quote before the comparison is fair. On a £35,000 EV those extras easily add £150–£200 per month.
Worked Example: £35,000 EV at Basic Rate
Let us put the two routes side by side for a 20% taxpayer earning £38,000 who wants a £35,000 electric car on a 48-month term.
Salary sacrifice route
| Item | Monthly |
|---|---|
| Gross salary sacrificed | £450 |
| Income tax saved (20%) | −£90 |
| Employee NIC saved (8%) | −£36 |
| Net cost of sacrifice | £324 |
| BIK tax (£35,000 × 4% × 20% ÷ 12) | +£23 |
| Effective monthly cost | £347 |
Insurance, maintenance, tyres and road tax are included — nothing else to pay.
Personal PCP route
| Item | Monthly |
|---|---|
| PCP payment (from net salary) | £420 |
| Comprehensive insurance | £85 |
| Servicing & tyres fund | £45 |
| Road tax (VED) | £15 |
| Total monthly cost | £565 |
The salary sacrifice route saves roughly £218 per month — over £10,400 across a four-year term. That is a saving of around 39%.
Higher-Rate Taxpayers Save Even More
A 40% taxpayer sacrificing the same £450 per month saves £180 in income tax plus £9 in NIC (2% on earnings above the higher-rate threshold). The BIK charge doubles to £47 per month at the higher rate, but the net cost still drops dramatically.
| Item | Basic rate (20%) | Higher rate (40%) |
|---|---|---|
| Gross sacrifice | £450 | £450 |
| Tax + NIC saved | £126 | £189 |
| Net sacrifice cost | £324 | £261 |
| BIK tax | £23 | £47 |
| Monthly cost | £347 | £308 |
Compared with the £565 PCP-plus-extras total, a higher-rate taxpayer on salary sacrifice saves around £257 per month — over £12,300 across four years. Employers also save 15% employer NIC on the sacrificed salary, and many pass part of that saving back to employees through a reduced monthly amount.
PCP, HP and Cash Purchase Compared
Not every employee has access to a salary sacrifice scheme. Here is how the three personal routes compare for the same £35,000 EV.
PCP (Personal Contract Purchase) — Low monthly payments with a balloon payment at the end. You pay from net income, do not own the car until the final payment, and must arrange your own insurance and servicing. Typical total cost over four years including deposit, payments, balloon and running costs: £30,000–£33,000.
HP (Hire Purchase) — Higher monthly payments than PCP but you own the car at the end. No balloon, but the overall interest cost is similar. Total outlay over four years: £32,000–£35,000 plus running costs.
Cash purchase — No interest charges, but you tie up a large lump sum. If you invest that cash at 4–5% you face an opportunity cost of around £5,000–£7,000 over the same period. Buying outright suits drivers who keep their cars well beyond five years.
In every scenario, salary sacrifice undercuts personal finance by 20–50% once tax, NIC and bundled running costs are factored in. The only way buying wins is if you plan to keep the vehicle for seven-plus years and have the capital available upfront.
When Buying Might Still Make Sense
Salary sacrifice is not available to everyone. You need an employer who runs a scheme, and your gross salary after the sacrifice must not fall below National Minimum Wage. There are a few other situations where buying could be the better choice:
- Self-employed drivers — Salary sacrifice is an employee-only benefit. If you run your own business, consider purchasing through your limited company instead (see our electric car through a limited company guide).
- Long-term ownership — If you typically drive a car for eight to ten years, spreading the purchase cost over that period reduces the annual outlay below a four-year lease.
- Pension impact — Sacrificing salary reduces your pensionable pay in some defined-contribution schemes. Check whether your employer calculates pension contributions on pre- or post-sacrifice earnings.
- Early-termination risk — If you leave your employer before the lease ends, you may face an early-exit charge equal to several months of payments.
Tracking Mileage Alongside a Salary Sacrifice Car
On a salary sacrifice company car your employer covers the vehicle’s running costs, so you do not claim HMRC mileage rates for that car. But if you also use a personal vehicle for business journeys — visiting clients, attending off-site meetings or travelling between workplaces — you can still claim 45p per mile for the first 10,000 miles and 25p thereafter.
Keeping a proper mileage log is essential. Tripbook records every journey automatically using GPS, tagging each trip as business or personal so you have an HMRC-ready record without manual effort. If you run both a company EV and a personal car, Tripbook lets you track mileage across multiple vehicles in a single app.
