What Lease Length Should I Choose? 24 vs 36 vs 48 Months

Short answer: 36 months suits most people. It's usually the best balance of monthly cost, warranty cover and freedom to change car. Go to 48 months if you want the lowest monthly payment and you're settled. Choose 24 months only if you genuinely need the flexibility - you'll pay for it.

Which Lease Length Is Best: 24, 36 or 48 Months?

Thirty-six months is the right answer for most UK drivers. It's long enough for the monthly cost to settle down, short enough that the car stays inside a typical three-year warranty and never needs an MOT under your care. Choose 48 for the cheapest monthly, 24 for flexibility.

That's the honest version, and we'd rather give it to you up front than dress it up. Around three years is where the numbers, the warranty and most people's appetite for the same car all line up. Everything else in this guide is about the cases where the default is wrong for you - and there are plenty of those.

One thing to be clear on before we go further, because it explains why term changes the price at all. A lease rental isn't the price of the car chopped into equal pieces. You're paying the gap between what the vehicle costs to acquire and what it's forecast to be worth at the end of the contract (its residual value), plus interest charges. A new car loses value fastest in its first couple of years, so a short term concentrates the expensive part of that curve into fewer payments.

How Does Lease Length Affect the Monthly Payment?

Longer terms almost always mean lower monthly payments, because the cost is spread across more months and the sharpest part of the car's value drop is diluted. But the total you hand over across the contract goes up, not down - you're simply buying more months of motoring.

An illustrative example, using obviously round numbers rather than a real quote. Say the same car, on the same mileage and the same initial rental profile, quotes £330 a month over 36 months and £300 a month over 48 months. On a 9+35 profile (nine months' rental paid up front, then 35 monthly payments) the 36-month deal costs £2,970 initially plus 35 × £330 = £11,550, so £14,520 in total. The 48-month version on 9+47 costs £2,700 up front plus 47 × £300 = £14,100, so £16,800 all in.

So the extra twelve months adds £2,280 - roughly £190 a month for that fourth year, which is less than either headline monthly. That's the real trade-off in a sentence: a longer term buys cheaper motoring per mile driven, at the cost of a bigger total commitment and an older car at the end.

24 vs 36 vs 48 Months Compared

Here's the practical comparison. Assume the same car, the same annual mileage and the same initial rental profile in each column - change any of those and the comparison stops meaning anything.

When Is a 24-Month Lease the Right Choice?

Two years is worth paying for when your circumstances might change, or when the car itself might date quickly. Job moves, a growing family, a relocation, or an electric car where charging and range are improving fast. You're buying an exit at a known date, and that convenience carries a real monthly premium.

The premium exists because a brand-new car sheds value quickest early on, and on a 24-month contract that drop is spread over fewer payments, plus interest charges. On some cars the difference between two and three years is modest; on others it's stark. It depends entirely on how the funder forecasts that particular model's value.

Who tends to pick 24 months?

In our experience it's people expecting change, drivers who simply like a new car often, and anyone leasing an EV for the first time who wants a short commitment while they work out whether the charging routine fits their life. If that's you, our electric car guide is worth ten minutes before you commit to any term.

Why Is 36 Months the Default for Most Drivers?

Three years is the sweet spot because several things line up at once: most manufacturer warranties run to three years, the first MOT isn't due until the third anniversary of registration, and the monthly payment has dropped substantially from the 24-month figure without stretching your commitment to four years.

According to GOV.UK, a car in England, Scotland and Wales needs its first MOT by the third anniversary of first registration (four years in Northern Ireland). Time a 36-month lease from delivery and the car goes back at or around that point. No MOT, no post-warranty repair bills, no worn-out consumables beyond routine servicing.

It's also the term most of the market is built around. Special offers, stock deals and manufacturer support tend to cluster on three-year contracts, which is why a 36-month quote often looks better value than the arithmetic alone would suggest. If you're weighing several cars, our guide on how to compare lease deals shows how to judge them properly.

When Does a 48-Month Lease Make Sense?

Four years works when the monthly figure is the deciding factor and your life is settled. Same house, same job, same family size, predictable mileage. You get the cheapest month-to-month motoring and the least hassle of reordering, in exchange for a bigger total commitment and a fourth year in an older car.

Be honest with yourself about that fourth year. The car will be out of a standard three-year warranty, an MOT will fall due, and tyres, brakes and wipers will be nearer the end of their life. None of that is a dealbreaker - it's just cost and admin that a 36-month lease sidesteps entirely. It's also the strongest case in the whole guide for adding a maintenance package, which rolls servicing, tyres and wear items into the monthly. Our guide on whether to add maintenance goes through the numbers.

One more consideration people forget: four years is a long time in electric cars. Battery technology, charging speeds and range have moved quickly, and a 2026 EV will feel less current in 2030 than a 2026 diesel will. That's not an argument against leasing an EV - if anything it's an argument for leasing rather than buying one, since the residual value risk sits with the funder, not you. It's an argument for thinking twice before locking an EV in for 48 months.

Warranty, MOT and Servicing on Longer Terms

Warranty length should influence your term more than most people let it. Most manufacturers cover three years, so a 48-month lease leaves a year uncovered. Brands with longer cover change the maths entirely - Kia offers seven years and Hyundai five, both subject to the manufacturer's terms and mileage limits.

If you're set on four years, choosing a car with five-year-plus cover removes the main objection to the longer term. It's one of the more useful pieces of advice we give, and it costs nothing to act on.

On that last point: the British Vehicle Rental and Leasing Association (BVRLA) publishes the industry-standard definition of acceptable wear, and funders assess returned vehicles against it. Fair wear and tear is deterioration from normal use, not damage from an impact or neglect. A longer lease doesn't change the standard, but it does give you more opportunity to fall outside it, so budget for a set of tyres and a couple of small repairs before handback on a four-year contract.

How Term and Annual Mileage Work Together

Term and mileage are priced together, not separately. A 48-month lease at 10,000 miles a year is a 40,000-mile contract; a 24-month lease at 20,000 a year is also 40,000 miles. The funder cares about total mileage at handback as much as the number of years, because both drive the car's forecast value.

Two practical consequences. First, if your mileage is high, a shorter term can protect you - four years at 20,000 miles a year puts an 80,000-mile car on the market, and residual forecasts fall away sharply at that sort of figure. Second, if you're uncertain about your mileage, uncertainty over four years is a much bigger gamble than over two. Excess mileage charges are set per mile in your contract and are unavoidable once you've exceeded the allowance.

Get the mileage right before you settle the term - our guide to choosing the right annual mileage covers how to work yours out honestly rather than optimistically.

So which should I decide first, term or mileage?

Mileage. It's a fact about your life, not a preference. Work out what you actually drive, add a sensible buffer, then look at what different terms cost at that figure.

Does Term Matter for Company Cars and BIK?

Yes, and mainly for electric company cars. Benefit in Kind (BIK) is the tax you pay on a car your employer provides for private use, and the zero-emission rate is scheduled to rise over the next few years. A longer term means you drive into higher rates - though from a low base.

Under HMRC's published company car appropriate percentages, fully electric cars are taxed at 4% of P11D value (the list price including options and delivery) for the 2026/27 tax year, rising to 5% in 2027/28, 7% in 2028/29 and 9% in 2029/30. Petrol and diesel cars sit far higher - broadly 15% to 37% depending on CO2, with a 4% supplement for non-RDE2 diesels. So a 48-month EV lease starting in the 2026/27 tax year will see the rate step up more than once during the contract.

Even so, the gap between an EV and a comparable petrol company car stays wide across a four-year term. Example, clearly illustrative: a £40,000 EV at the 4% rate for 2026/27 gives a taxable benefit of £1,600, costing a 40% taxpayer £640 a year, or about £53 a month. Nobody chooses a shorter lease purely to dodge a one-point BIK rise.

If you're funding through your employer, salary sacrifice deserves a look before you fix the term - schemes usually run to set contract lengths, so check what's available. Our salary sacrifice page explains how it works alongside business contract hire.

A Five-Question Checklist for Picking Your Term

Run through these five questions and the answer usually picks itself. Where they conflict, weight the first two most heavily - flexibility and affordability are the two things people actually regret getting wrong.

And do price both. We'd always rather quote a customer on two terms than assume - the difference between 36 and 48 varies enormously by model, and occasionally a manufacturer's support makes the shorter contract the better buy outright. That's a five-minute conversation, not a research project.

One last thought before the FAQs. Nearly every customer we speak to who regrets their term regrets going too long, not too short - and almost always because something changed. If you're genuinely torn between 36 and 48 months and the monthly saving isn't the thing making the deal possible, take the 36.
