Is an Electric Company Car Worth It in the UK?

For most PAYE employees in the UK, an electric company car is worth it in 2026. HMRC sets the Benefit-in-Kind (BiK) rate for a fully electric vehicle at just 4% for 2026/27, compared with 17% to 37% for petrol and diesel cars. A salary sacrifice arrangement also cuts Income Tax and National Insurance on the monthly lease cost. That said, it is not automatically worth it for everyone, and the honest picture includes some caveats.

Is an electric company car worth it in 2026?

The short answer is yes, for most higher and basic-rate taxpayers who have access to a company car or salary sacrifice scheme. The headline reason is the BiK rate gap.

Pure electric cars carry a 4% BiK appropriate percentage for 2026/27, rising to 5% in 2027/28, 7% in 2028/29 and capped at 9% from 2029/30, as confirmed after the November 2025 Autumn Budget. Petrol and diesel cars sit at roughly 17% to 37% for 2026/27. That means an EV is taxed at a fraction of the rate applied to a comparable petrol model.

Worth it if:

• You pay Income Tax (basic or higher rate) and your employer offers a company car or salary sacrifice scheme
• You drive enough miles that the reduced running costs add to the financial case
• Your cash pay after sacrifice would remain above the National Minimum Wage

Less likely to be worth it if:

• Sacrifice would take your pay below minimum wage, so you cannot access a full salary sacrifice arrangement
• You want to own your car outright and build equity in an asset
• Your job tenure is very short and early-termination penalties could apply

How is electric company car tax (BiK) calculated?

BiK tax is not complicated once you see the formula. Your taxable benefit equals the car’s P11D value multiplied by the appropriate BiK percentage. The P11D value is broadly the list price of the car including options, less any capital contribution you make. That taxable benefit is then taxed at your marginal Income Tax rate.

The formula: P11D value x BiK % = taxable benefit; taxable benefit x your tax rate = annual BiK tax

A worked example: a £59,000 Tesla has a taxable benefit of approximately £2,360 in 2026/27 (4% of £59,000). A higher-rate taxpayer at 40% pays roughly £944 a year in BiK tax on that car.

For a £40,000 electric car at 4%, the taxable benefit is around £1,600. A basic-rate (20%) driver pays approximately £320 a year; a higher-rate (40%) driver approximately £640 a year (figures vary, verify current data).

One additional point: cars emitting 75g/km CO2 or below are exempt from the OpRA “higher of” rule. That means the low BiK rate applies even under salary sacrifice, so you do not lose the advantage by taking the car through a sacrifice arrangement.

Take-home cost: electric vs petrol company car

The table below puts the comparison in one place. The petrol row applies a representative 30% BiK band to a £40,000 P11D; the actual figure depends on the specific car’s CO2 band, which ranges from 17% to 37%, so treat it as illustrative.

Car	P11D	BiK %	Taxable benefit	Annual tax (basic 20%)	Annual tax (higher 40%)
£40,000 EV	£40,000	4%	£1,600	£320	£640
£40,000 petrol (illustrative, ~30% band)	£40,000	~30%	£12,000	£2,400	£4,800
£59,000 EV	£59,000	4%	£2,360	£472	£944

Petrol figures are illustrative. Exact BiK bands for petrol and diesel run from 17% to 37% in 2026/27 depending on CO2 emissions. Check Fleet News BiK tables for your specific car.

The difference is stark. A higher-rate taxpayer in a £40,000 petrol company car pays roughly £4,800 a year in BiK tax. In a like-for-like electric car, they pay approximately £640. That is a saving of around £4,160 a year on tax alone.

Via salary sacrifice the gross sacrifice also reduces Income Tax and National Insurance, with typical savings around £1,680 a year for basic-rate taxpayers and £2,520 a year for higher-rate taxpayers, based on a representative monthly sacrifice (figures vary, verify current data).

Should you take it as salary sacrifice or a traditional company car?

There are three main routes to an electric company car, and they work differently.

Salary sacrifice takes the monthly lease cost from your gross pay before Income Tax and National Insurance are applied. You save on both taxes on top of the low BiK rate. This is now the dominant route to an EV company car for most employees.

Traditional employer-provided company car works the same way on BiK, but you do not get the Income Tax and National Insurance saving on the sacrifice amount. You pay BiK tax on the car’s value, and the employer covers the lease. The tax advantage versus petrol is still very large.

Car allowance is paid as additional salary and taxed accordingly, so you lose the BiK benefit entirely. A car allowance may suit drivers who want to own their car or who change vehicles frequently, but for the pure tax saving on an EV it does not compare.

Employers benefit from salary sacrifice too: employer National Insurance is 15% from April 2025, and employers save 15% on each pound sacrificed. Many pass a portion of that saving back to staff in the form of servicing, insurance or charging equipment included in the package.

Do you still pay road tax (VED) on an electric company car?

This is the change that most “is it worth it” articles skip, and it does affect the full-cost picture.

Electric vehicles lost their Vehicle Excise Duty (VED) exemption on 1 April 2025. New EVs now pay the standard VED rate after their first year of registration, in line with petrol and diesel cars.

Two points to factor in:

• New zero-emission cars registered from 1 April 2025 pay the lowest first-year rate (currently £10), then the standard rate in subsequent years
• The Expensive Car Supplement, a surcharge applied to cars above a set price threshold, now covers EVs; the threshold was raised to £50,000 for electric cars from April 2026 (versus £40,000 for other cars), and the supplement runs at approximately £425 to £440 a year for five years (figures vary, verify current data against GOV.UK VED tables)

For a company car arrangement, VED is typically paid by the employer or leasing company, so it affects the total cost of the scheme rather than your monthly BiK tax bill. On a salary sacrifice arrangement, check whether VED is included in the monthly cost the provider quotes.

When is an electric company car NOT worth it?

The BiK advantage is real, but there are situations where taking an electric company car does not stack up.

• Your sacrifice would breach minimum wage: salary sacrifice cannot reduce your cash pay below the National Minimum Wage, which is £12.21 per hour from April 2025. If the monthly sacrifice would take you below that threshold, you cannot join the scheme. Lower earners therefore see less benefit or none at all.
• You want equity in the car: a company car or salary sacrifice arrangement means you never own the vehicle. If you prefer to build an asset or want flexibility to sell the car, buying privately may suit you better.
• Very low mileage or very short job tenure: the scheme saves you money month by month, but if you leave the job the car typically goes back. Early-termination clauses can reduce or eliminate the financial benefit. Very low-mileage drivers also see a smaller running-cost saving against petrol.
• Potential pension and mortgage impact: because you give up gross salary, pension contributions calculated as a percentage of pay may be based on the lower figure, depending on your scheme rules. Mortgage lenders may also assess affordability against your reduced salary. Neither is a dealbreaker for most people, but both are worth checking before you sign.
