Salary Sacrifice vs Personal Lease for an EV: Which Saves More?

Salary sacrifice is substantially cheaper than personal lease for an EV in almost every scenario. The difference comes down to two things: salary sacrifice deducts the car cost from your gross income (before tax), while personal lease payments come from your net income (after tax). On top of that, the Benefit-in-Kind (BIK) rate for a fully electric car in 2026/27 is just 4%, which is the only additional tax charge under salary sacrifice, and it is small. For a higher-rate taxpayer, salary sacrifice is typically 30–50% cheaper than personal contract hire for the same car. For basic-rate taxpayers, the saving is smaller but still meaningful, around 20–30%.

The only situation where personal lease pulls ahead is if your employer does not offer a salary sacrifice scheme or you cannot participate (for example, because the sacrifice would take your pay below the National Minimum Wage).

The core calculation: why salary sacrifice wins

Under personal lease (PCH), you pay the monthly rental from money you have already been taxed on. To find £400 per month from net pay, a 40% taxpayer needs to earn approximately £680 gross, because they keep only 58p of each pound after income tax and NI.

Under salary sacrifice, the £400 monthly lease cost is deducted from gross pay before PAYE is applied. You pay tax and NI on the reduced salary. The effective cost is not £400 from net pay but roughly £240 from pre-tax earnings for a 40% taxpayer (£400 minus 40% income tax saving of £160, minus 2% NI saving of £8, plus the BIK charge).

	Personal Lease (PCH)	Salary Sacrifice
Monthly rental/sacrifice	£400	£400
How it’s paid	From net pay	From gross pay
Income tax saving	None	£160/month (40%)
Employee NI saving	None	£8/month
BIK charge (£35,000 × 4% × 40%)	None	£47/month
Effective monthly cost (40% taxpayer)	£400	~£239
Annual effective cost	£4,800	~£2,868
3-year total effective cost	£14,400	~£8,604
3-year saving	,	~£5,796

For a basic-rate (20%) taxpayer on the same car:

	Personal Lease	Salary Sacrifice
Monthly sacrifice	£400	£400
Income tax saving	None	£80/month
NI saving	None	£32/month
BIK (£35,000 × 4% × 20%)	None	£23/month
Effective monthly cost	£400	~£311
Annual saving	,	~£1,068
3-year saving	,	~£3,204

What does personal lease include that salary sacrifice does not?

This is a fair comparison point. Salary sacrifice packages typically include more than a bare PCH deal:

Typical salary sacrifice inclusion:

• Vehicle lease
• Road tax (VED)
• Maintenance and tyres
• Breakdown cover
• Sometimes insurance
• Sometimes home charger installation

Typical personal lease (PCH) inclusion:

• Vehicle lease only
• You arrange your own insurance, maintenance, breakdown and VED

When comparing on a like-for-like basis (adding insurance, maintenance and breakdown cover to the PCH figure), the salary sacrifice advantage widens further. A basic-rate taxpayer who adds £80 per month for insurance and £30 per month for a maintenance package to their PCH pays £510 per month total. The salary sacrifice equivalent is around £311 per month.

Does the car choice matter?

The proportional saving from salary sacrifice is fixed as a percentage of the gross sacrifice: around 28% for a 20% taxpayer and 42% for a 40% taxpayer. A more expensive car (larger sacrifice) produces a larger absolute saving in pounds per month. The BIK charge scales with P11D value, but at 4% the BIK remains small relative to the sacrifice saving at any price point.

A driver sacrificing £600 per month saves approximately £168 per month in tax and NI (20% rate) versus £252 per month (40% rate). A driver sacrificing £300 per month saves half those amounts. The percentage saving is identical regardless of car price; the absolute pounds per month is larger on a more expensive car.

What are the practical differences?

Factor	Salary Sacrifice	Personal Lease
Access	Requires employer to offer the scheme	Anyone can take a personal lease
Tax saving	Significant (20–50% of gross cost)	None
BIK tax	4% on EV P11D value	Not applicable
Early exit risk	Early termination fees may apply	Standard PCH exit terms
Effect on mortgage	Reduces stated gross income	Does not affect gross income
Car ownership	Employer owns/leases	You lease personally
Minimum wage constraint	Yes (cannot sacrifice below NMW)	No
Car choice	Limited to scheme provider’s range	Any car from any dealer

The mortgage consideration

Salary sacrifice reduces your gross salary as declared on payslips. This can affect mortgage affordability calculations. Lenders typically use gross salary figures to determine borrowing limits. If you are planning to apply for a mortgage within the term of a salary sacrifice agreement, speak to a mortgage broker first. Many lenders will add back salary sacrifice when calculating affordability, but not all do. If you intend to move house in the next 1–2 years, understand the mortgage implications before signing a 36 or 48-month salary sacrifice contract.

What if my employer does not offer salary sacrifice?

If your employer provides a company car through a standard Business Contract Hire arrangement (where they lease and provide the car, you pay BIK), your income tax saving on the lease cost is absent, but you still benefit from the 4% BIK rate on the electric car. This is better than a personal lease on a like-for-like BIK basis, but lacks the pre-tax salary saving.

In this case, the comparison is: company car (BIK tax only) vs personal lease (no BIK, all costs from net pay). For an EV at 4% BIK, a company car still wins on total cost for most drivers, because the BIK tax on an EV is so small.

Our verdict

If you can access a salary sacrifice scheme, take it. The saving over personal lease is real, consistent, and significantly larger than most drivers expect when they first see the numbers. A higher-rate taxpayer saving £150–£250 per month on an EV salary sacrifice accumulates £5,400–£9,000 over a three-year agreement. That is a substantial benefit.

Personal lease is the right route only if salary sacrifice is unavailable to you, or if you specifically need a car outside the range your scheme provider offers. For most UK employees with access to a scheme, salary sacrifice is the clear winner.
