## Key takeaways

- Pure electric company cars attract just 3% Benefit-in-Kind (BiK) tax in 2026–27, rising to 4% in 2027–28 and 5% in 2028–29.
- Plug-in hybrids with 30–39 miles of electric range face 8% BiK; those with 70+ miles get 5%.
- For a higher-rate taxpayer, a £45,000 EV costs roughly £540 in annual BiK tax versus £2,160 for a comparable plug-in hybrid.
- Running costs heavily favour EVs — roughly 2–3p per mile for home charging versus 12–15p per mile for a hybrid on petrol.

The company car tax system has been the single biggest driver of electric vehicle adoption in the UK — and in 2026, it still tilts the playing field decisively towards pure EVs. But the gap is narrowing slowly, and for some drivers a plug-in hybrid remains the pragmatic choice. This guide compares the tax treatment, running costs, and real-world practicality of both options so you can decide what makes sense for your business and your mileage. *This is general information, not tax advice — consult your accountant for your specific circumstances.*

## Benefit-in-Kind (BiK): the tax that drives the decision

Company car tax — formally Benefit-in-Kind (BiK) — is calculated as a percentage of the car's P11D value (its list price plus options and delivery). That percentage is determined by the car's CO₂ emissions and, for hybrids, its electric-only range.

The rates for **2026–27** (confirmed by HMRC) are:

- **Pure electric (0 g/km CO₂):** 3% BiK
- **Plug-in hybrid, electric range 70+ miles:** 5% BiK
- **Plug-in hybrid, electric range 40–69 miles:** 8% BiK
- **Plug-in hybrid, electric range 30–39 miles:** 12% BiK
- **Plug-in hybrid, electric range <30 miles:** 14% BiK
- **Petrol/diesel, 51–54 g/km:** 15% BiK (and climbing steeply from there)

The BiK rate is then multiplied by your income tax band to arrive at the annual tax bill. For a **basic-rate taxpayer (20%)**, the cost is BiK rate × P11D value × 20%. For a **higher-rate taxpayer (40%)**, multiply by 40%.

## Real tax bills compared

Let us take two realistic 2026 company cars at a similar price point:

**Option A: Pure EV** — P11D value £45,000, 0 g/km CO₂.
- BiK rate: 3%
- Taxable benefit: £45,000 × 3% = £1,350
- Annual tax for basic-rate payer: £1,350 × 20% = **£270**
- Annual tax for higher-rate payer: £1,350 × 40% = **£540**

**Option B: Plug-in hybrid** — P11D value £43,000, electric range 35 miles.
- BiK rate: 12%
- Taxable benefit: £43,000 × 12% = £5,160
- Annual tax for basic-rate payer: £5,160 × 20% = **£1,032**
- Annual tax for higher-rate payer: £5,160 × 40% = **£2,064**

For a higher-rate taxpayer, the EV saves roughly **£1,500 per year in BiK tax alone**. Over a typical three-year lease cycle, that is £4,500 — enough to buy a home charger several times over.

## Running costs: the bigger picture

Tax is only part of the equation. Running costs differ sharply:

| Cost category | Pure Electric | Plug-in Hybrid |
|---|---|---|
| Home charging (per mile) | 2–3p (off-peak tariff, ~7.5p/kWh) | 2–3p on electric; 12–15p on petrol |
| Public rapid charging (per mile) | 8–12p | 8–12p on electric |
| Fuel (petrol at £1.45/litre, 45 mpg) | N/A | ~15p per mile |
| Annual VED (road tax) | £0 until April 2025; £10 discount thereafter | £10 discount versus petrol equivalent |
| Servicing | Lower — fewer moving parts, less brake wear | Similar to petrol — engine, oil, filters |
| Typical annual fuel cost (10,000 miles) | £200–£300 (home charged) | £800–£1,200 (mixed use) |

The EV wins on running costs across every category. For a driver covering 10,000 miles per year, the fuel saving alone can be £500–£900 annually. Over three years, that adds another £1,500–£2,700 to the EV's advantage.

## The capital allowance bonus for businesses

If your business buys the car outright (rather than leasing), a **new zero-emission car** qualifies for a **100% first-year capital allowance**. This means the full purchase price can be deducted from taxable profits in the year of acquisition.

A business paying 25% corporation tax that buys a £45,000 EV can reduce its tax bill by up to **£11,250** in year one. A plug-in hybrid with CO₂ emissions above 50 g/km qualifies only for the standard 18% writing-down allowance — a much smaller and slower tax benefit.

## Practical trade-offs: where hybrids still win

The financial case for EVs is strong, but the practical case is not universal:

**Range anxiety is real for some drivers.** A 2026-model EV typically offers 250–350 miles of real-world range. That covers the vast majority of UK journeys — the average car trip is under 10 miles, according to DfT National Travel Survey data. But for sales representatives covering 300+ miles in a day, or drivers in rural areas with sparse charging infrastructure, a plug-in hybrid eliminates range concerns entirely.

**Charging access is not equal.** Drivers with off-street parking and a home charger enjoy the lowest costs and greatest convenience. Those in flats, terraced streets, or rented accommodation may rely on public charging, which is more expensive and less convenient. For these drivers, a hybrid that can run on petrol when needed reduces dependence on infrastructure that may not yet meet their needs.

**Upfront cost still matters.** EVs carry a purchase premium. While the gap has narrowed — some Chinese and Korean brands now offer EVs within £1,000–£2,000 of a petrol equivalent — premium European EVs remain £5,000–£10,000 more expensive than comparable petrol or hybrid models. For businesses with tight capital budgets, the lower purchase price of a hybrid may be decisive.

## Head-to-head summary

| Factor | Pure EV | Plug-in Hybrid |
|---|---|---|
| BiK rate 2026–27 | 3% | 5–14% (range-dependent) |
| Annual BiK tax (higher-rate, £45k car) | ~£540 | £900–£2,520 |
| Fuel cost per mile | 2–3p (home) | 2–15p (mix-dependent) |
| 100% first-year allowance | Yes (new only) | No |
| Range flexibility | 250–350 miles per charge | 300–500 miles (petrol backup) |
| Charging dependency | High | Low |
| ULEZ/CAZ compliance | Exempt | Exempt in electric mode |

## Who each suits

**Pure EV suits:**
- Drivers with off-street parking and home charging.
- Anyone doing predominantly sub-200-mile daily journeys.
- Businesses that can claim the 100% first-year allowance.
- Higher-rate taxpayers who gain the most from the BiK differential.

**Plug-in hybrid suits:**
- Drivers without reliable home charging access.
- High-mileage drivers who regularly exceed 250 miles in a day.
- Those in areas with limited public charging infrastructure.
- Anyone who wants electric for local trips and petrol for long ones without planning charging stops.

## The verdict

In 2026, a pure electric company car is the clear financial winner for most drivers — the BiK gap is large, running costs are lower, and the capital allowance benefit is substantial. The case for a plug-in hybrid has narrowed to a specific set of circumstances: no home charging, very high mileage, or rural operation where the charging network remains thin.

If you can charge at home and your daily driving fits comfortably within an EV's range, the numbers point decisively towards electric. If you cannot, a plug-in hybrid with the longest electric range you can afford — ideally 70+ miles to capture the 5% BiK rate — is the next-best option. Either way, the days of a pure petrol or diesel company car making financial sense are firmly behind us.

## Frequently asked questions

### What is the BiK rate for electric company cars in 2026?

The Benefit-in-Kind rate for pure electric vehicles is 3% in the 2026–27 tax year, rising by 1 percentage point each year to 4% in 2027–28 and 5% in 2028–29. These rates were confirmed by HMRC in the Autumn Budget 2024 and remain current as of mid-2026.

### Are plug-in hybrids still worth it as company cars?

They can be — if your driving pattern genuinely uses the electric range for most journeys. A PHEV with 70+ miles of electric range attracts 5% BiK (close to the EV rate), while one with 30–39 miles faces 8%. But if you rarely plug in and mostly run on petrol, you pay higher BiK and higher fuel costs — the worst of both worlds.

### What about the 100% first-year allowance for EVs?

Businesses purchasing a new zero-emission car can claim a 100% first-year capital allowance, writing off the full cost against taxable profits in the year of purchase. This applies to new EVs only — not used ones and not hybrids. The allowance is scheduled to remain in place until at least March 2027.
