Option A

A vehicle provided by your employer, usually taxed as a benefit-in-kind based on list price, CO2 emissions and your tax band.
Company car vs car allowance: which is better for your finances?
Updated June 2026 9 min read
Quick verdict
A company car can be excellent value for low-emission vehicles, especially electric cars with low benefit-in-kind rates. A car allowance gives more choice and avoids company car BIK, but it is taxed like salary and you carry running-cost risk.
Option B
Car allowance
Extra cash paid through payroll so you can buy, finance or run your own car, with business mileage usually claimed separately.
Side-by-side comparison
Choose a company car when tax is low, the employer covers major costs, or you drive high business mileage. Choose an allowance when you want control over the vehicle and the after-tax allowance covers ownership costs.
