Every growing SME hits the same question sooner or later: do you buy the company car outright, or do you lease it? It sounds simple enough, but the answer depends on where your business is right now, how much spare capital you’re sitting on, and how you want your balance sheet to look in 12 months.
Get it wrong and you’ll either tie up cash you badly need or commit to monthly payments that don’t suit how your team actually uses vehicles. There’s a real case for leasing, and there’s a real case for buying. Let’s see how the two stack up where it matters most, so you can make the right call for your business.
What Buying Outright Actually Costs an SME
The Sticker Price
When you buy a car for the business, the sticker price is only the beginning. A mid-range saloon suitable for client visits and motorway miles will set you back somewhere around £30,000 to £40,000. That’s cash leaving the business on day one, and it’s cash you can’t use for stock, hiring, or marketing.
Depreciation
Then there’s depreciation. Most new cars lose roughly 15% to 30% of their value in the first year alone, and that rate doesn’t slow down much in year two. After three years, you could be looking at a vehicle worth 40% to 50% less than you paid for it.
If you’re an SME watching every pound, that’s a significant hidden cost that won’t show up on the invoice but will absolutely show up when you try to sell the car.
How Does Tax Factor Into It?
From a tax perspective, cars don’t qualify for the Annual Investment Allowance (AIA). However, if you buy a new and unused electric car or car with zero CO2 emissions before April 2027, you can claim 100% first year allowances, letting you deduct the full purchase price in the year you buy.
For other vehicles, capital allowances may be available depending on the type of car and its CO2 emissions. The rules can vary, so it’s worth checking the government’s guidance on capital allowances for business cars or speaking to your accountant.
How a Business Car Lease Works in Practice
With a business car lease, you’re paying for the use of the vehicle over an agreed term, typically between 24 and 48 months. You’ll put down an initial rental, which can be as low as only one month’s payment, and then pay a fixed amount each month until the contract ends. At the end, you simply hand the car back.
The monthly cost covers depreciation and finance charges, but because you never own the vehicle, you don’t carry the depreciation risk yourself. If the used car market drops, that’s the leasing company’s problem. Your cost stays exactly the same from month one to the final payment.
For VAT-registered businesses, there can be a benefit on lease rentals. Most companies who lease a qualifying car for business purposes can usually recover 50% of the VAT charged.
Cash Flow: Where Most SMEs Feel the Difference
This is where the comparison gets real. An SME with £35,000 in the bank could spend it on one car, or it could lease the same model for around £400 to £500 per month (depending on the car and contract terms) and keep that capital working.
Put differently, the initial rental on a lease might be £1,500 to £2,000. Compare that to paying the full purchase price and the difference is stark. That freed-up capital can go towards a new hire, a marketing push, or simply sitting in a reserve fund for quieter months. For businesses at a growth stage, liquid cash is often worth far more than an asset that loses value the moment it’s driven off the forecourt.
A Quick Side-by-Side
Upfront cost: Buying outright requires the full purchase price. Leasing requires an initial rental, typically ranging from one to twelve months’ worth of payments.
Depreciation risk: Falls on you when you buy. Falls on the leasing company when you lease.
VAT recovery: Usually limited to nil on a purchased car with private use. For VAT-registered businesses, usually up to 50% of the VAT on lease rentals may be recoverable, as noted above.
Mileage flexibility: Unlimited when you own the car. Capped within your lease contract.
End of term: With an outright purchase, you sell the car (and absorb any shortfall) or trade in. With a lease, you hand the leased car back and choose your next vehicle.
Points to Remember
A business that runs high-mileage vehicles and wants long-term ownership may find buying works well over time, though this will depend on the specific deal, maintenance costs, and how the vehicle holds its value.
That said, there’s no single correct answer. For most UK SMEs at a growth stage, leasing can offer a more predictable and cash-flow-friendly route to putting the right vehicles on the road. It removes the depreciation gamble and keeps capital where it’s needed most. The key is to match the funding route to where your business actually is right now, not where a brochure tells you it should be.
