For many women running a UK business, a car is one of the largest fixed costs. If you need a brand new vehicle, leasing is usually the cheapest way to afford a brand new car compared with hire purchase, a PCP or paying cash upfront. SMMT data from 2024 shows the UK new car market reached 1.95 million registrations, and the majority of those acquired by consumers and small firms were funded through finance rather than savings. The British Vehicle Rental and Leasing Association (BVRLA) also reports that contract hire remains the dominant form of business car funding.

But “cheapest” depends on how you use the car, your tax position and whether you actually want to own it. This guide compares the main routes and explains what to check before signing.

Leasing as the cheapest way to afford a brand new car

In most cases, yes. Business contract hire, often called leasing, means you rent the car for a fixed term, usually 24 to 48 months, and return it at the end. You pay an initial rental, typically three, six or nine monthly payments, followed by fixed monthly rentals. Because you are only covering depreciation plus interest, not the full purchase price, the monthly cost is usually lower than hire purchase or a loan.

The main alternatives are:

• Personal Contract Purchase (PCP): Monthly payments plus a large optional final payment if you want to own the car.
• Hire purchase (HP): Monthly payments until you own the vehicle outright.
• Business or personal loan: You borrow the full price and own the car from day one.
• Cash: You pay the full price upfront and absorb all depreciation.

PCP monthly payments are often higher than leasing because the finance company prices in the option to buy. HP spreads the full purchase price plus interest, so monthly costs are usually highest. Cash avoids interest but ties up capital in an asset that loses value.

Why leasing often beats PCP and hire purchase

With business contract hire, the monthly rental is based on the difference between the car’s list price and its predicted residual value at the end of the lease. A car that holds its value well can be surprisingly affordable to lease. Even a car that depreciates heavily can work out cheaper than buying because you never own the depreciating asset.

Leasing also keeps capital in your business. For women founders managing cash flow, keeping a lump sum for stock, payroll or tax bills can be more valuable than owning a car. Our guide to 5 tips to improve cash flow for UK business owners explains how to protect working capital.

Tax relief and VAT on a leased business car

Tax treatment is where leasing can pull further ahead for business use. If you are self-employed or run a limited company, lease payments can normally be claimed as an allowable business expense, reducing your taxable profit. For a car used partly for private journeys, you claim only the business proportion.

VAT treatment depends on use. HMRC rules state that if a leased car has any private use, you can reclaim only 50% of the VAT on the lease payments. If the car is used exclusively for business and is not available for private use, you can reclaim 100% of the VAT. This is a common audit point, so keep a mileage log.

For company cars, the benefit-in-kind (BIK) tax charge is based on CO2 emissions. HMRC has confirmed that for the 2026/27 tax year, the BIK rate for a zero-emission company car is 3%, rising to 4% in 2027/28 and 5% in 2028/29. This makes electric cars far cheaper as company cars than petrol or diesel equivalents, which can attract BIK rates of 20% or more.

Depreciation: the cost you do not see until you sell

Depreciation is usually the single largest cost of car ownership. Data from vehicle valuation specialists such as CAP HPI suggests a typical new car loses between 20% and 30% of its value in the first year and around 50% to 60% over three years. The UK used market is large, but prices are unpredictable, which makes owning a depreciating asset risky for a small business.

With leasing, that risk sits with the finance company. Provided the car is within the agreed mileage and fair wear-and-tear guidelines, you simply hand it back. This turns a depreciating asset into a predictable monthly cost, which makes budgeting easier.

What to check before you lease

Leasing is not automatically the right choice. Check these points before committing:

• Mileage allowance: Excess mileage charges can be expensive. Estimate your annual business and personal mileage accurately.
• Maintenance: A maintenance package adds to the monthly cost but covers servicing, tyres and MOT. Compare it against paying separately.
• Initial rental: A larger upfront payment reduces the monthly rental, but it increases your cash outlay at the start.
• FCA rules: The Financial Conduct Authority banned discretionary commission arrangements for motor finance from 28 January 2021. In 2024 and 2025 it investigated historic arrangements and set out a redress scheme. Check whether any broker is FCA-authorised and transparent about commission.
• Early termination: Ending a lease early can be costly. Make sure the term matches how long you expect to need the car.

If you are self-employed, only business-related costs are allowable. Our allowable expenses self employed UK guide sets out what HMRC accepts.

When buying outright can still make sense

Leasing is usually the cheapest way to fund a new car if you want low monthly payments and no ownership risk. But buying outright can work if you plan to keep the car for many years, drive very high mileage, or want to modify the vehicle. Once a car is paid off, the only costs are running costs, though you still face depreciation when you eventually sell.

Action steps before you sign a lease

1. Calculate your annual mileage and decide whether you need to own the car.
2. Compare business contract hire quotes against PCP and HP for the same model.
3. Check the 2026/27 BIK rates if you are considering a company car, especially for electric vehicles.
4. Confirm your VAT recovery position with your accountant based on business versus private use.
5. Verify that any broker or finance provider is FCA-authorised.

Leasing remains the cheapest way to afford a brand new car for most UK business owners who want predictable costs, minimal upfront capital and protection from depreciation. Match the finance route to your tax position and mileage, and the monthly saving can free up cash for the rest of your business.
