Business car leasing (Business Contract Hire or BCH) is one of the most tax-efficient ways for a UK company or sole trader to provide a vehicle. The tax benefits can be significant — particularly for electric and low-emission cars — but the rules are complex. This guide covers the key points.

How Business Contract Hire Works

Business Contract Hire (BCH) works the same way as personal PCH: you pay an initial rental followed by fixed monthly payments, and hand the car back at the end. The key differences are:

  • The contract is in the company's name (or your name as a sole trader)
  • Prices are quoted excluding VAT
  • You can reclaim some or all of the VAT
  • The lease payments are a deductible business expense

VAT Recovery on Business Leases

VAT recovery is one of the main reasons businesses lease rather than buy. The rules are:

UseVAT Recovery on Lease RentalsVAT Recovery on Maintenance
100% business use100% recoverable100% recoverable
Mixed business and personal use50% recoverable (HMRC block)100% recoverable
100% personal use0% recoverable0% recoverable

In practice, most company cars have some personal use (commuting counts as personal), so the standard position is 50% VAT recovery on lease rentals and 100% on maintenance. This is often referred to as the “HMRC 50% block.”

Pro Tip: If a vehicle is genuinely used 100% for business (for example, a pool car kept at business premises), you can reclaim 100% of the VAT. However, HMRC may challenge this, so keep clear records showing the car is never used for personal journeys.

Corporation Tax Deduction

For limited companies, the full lease rental (including the non-recoverable VAT) is deductible against corporation tax. However, there is a restriction for higher-emission cars:

CO2 EmissionsDeduction Allowed
0 g/km (pure electric)100% of lease rental
1–50 g/km (PHEV)100% of lease rental
Over 50 g/km85% of lease rental

For sole traders, the same rules apply against income tax. The lease cost is an allowable expense, subject to the same CO2-based restriction.

Benefit in Kind (BIK) for Employees

If an employee (including a director) uses a leased company car for personal use, they must pay Benefit in Kind (BIK) tax. The amount depends on the car's list price and CO2 emissions.

CO2 EmissionsBIK Rate (2025/26)BIK on £40,000 Car (20% taxpayer)BIK on £40,000 Car (40% taxpayer)
0 g/km (pure EV)2%£160/year£320/year
1–50 g/km (PHEV)2–14%£160–£1,120/year£320–£2,240/year
100 g/km24%£1,920/year£3,840/year
150+ g/km37%£2,960/year£5,920/year

The BIK rate for pure electric vehicles is just 2% — meaning an employee driving a £40,000 electric company car pays just £160 per year in tax (if a 20% taxpayer). This makes electric company cars extraordinarily tax-efficient.

The Electric Vehicle Advantage

Electric vehicles offer a triple tax benefit for businesses:

  1. 100% corporation tax deduction on lease rentals (no 15% restriction)
  2. 2% BIK rate for employees (vs up to 37% for petrol/diesel)
  3. No road tax for zero-emission vehicles registered before April 2025 (standard rates apply after)

Employer's National Insurance

The employer also pays Class 1A National Insurance on the BIK value at 13.8%. For a £40,000 electric car with a 2% BIK rate, the employer's NI cost is just £110 per year. For a 37% BIK petrol car, it would be £2,035 per year.

Lease vs Purchase for Business

The choice between leasing and purchasing a company car depends on several factors, but leasing is generally preferred because:

  • Lease payments are fully deductible (subject to CO2 rules) without capital allowance complications
  • No large capital outlay required
  • VAT recovery on rentals (not available on purchased cars)
  • Predictable costs with optional maintenance packages
  • No disposal hassle at the end
⚠️ Important Tax Notes
  • Tax rules and BIK rates change annually — always check the latest HMRC guidance
  • The 2% EV BIK rate is confirmed until April 2028, rising to 3% in 2028/29 and 4% in 2029/30
  • Salary sacrifice schemes for EVs can offer additional savings but have different tax treatment
  • Always consult a qualified accountant for advice specific to your business

Final Thoughts

Business car leasing offers genuine tax advantages, especially for electric and low-emission vehicles. The combination of VAT recovery, corporation tax deductions, and ultra-low BIK rates on EVs makes leasing an electric company car one of the most tax-efficient employee benefits available in the UK.

However, the rules are complex and change regularly. Always work with a qualified accountant to ensure you are maximising the benefits and staying compliant.

Frequently Asked Questions

Yes. Sole traders can enter into a Business Contract Hire agreement. The lease payments are deductible against income tax (subject to CO2 restrictions), and you can reclaim 50% of the VAT on rentals if the car has some personal use. Keep records of business vs personal mileage.
The Benefit in Kind rate for pure electric vehicles (0 g/km CO2) is 2% for the 2025/26 and 2026/27 tax years. It will rise to 3% in 2028/29 and 4% in 2029/30. This makes EVs by far the most tax-efficient company car option.
Only if the car is used exclusively for business (no personal use at all, including commuting). In practice, most company cars have some personal use, so the standard position is 50% VAT recovery on the lease rental. You can reclaim 100% of VAT on maintenance regardless of personal use.
Leasing is generally more tax-efficient because you can reclaim VAT on rentals (not possible on purchases), deduct the full rental as a business expense, and avoid the complexity of capital allowances. However, if you plan to keep the car long-term, purchasing may work out cheaper overall.
You remain liable for the full lease term. If your business closes, you will need to negotiate an early termination with the leasing company, which typically involves paying around 50% of the remaining rentals. Personal guarantee requirements vary by provider.
