Lease or buy? It is one of the most consequential — and most confused — decisions in personal motoring. Dealers push PCP and lease deals with seductive monthly figures; traditionalists insist buying outright is the only sane route; and the maths genuinely depends on your circumstances. Worse, it is not a one-time decision: the right answer changes as your life, mileage and the market change. This guide explains how often you should revisit the decision, the maths that matters, and which option suits different UK drivers.
What leasing and buying actually mean in 2026
First, clarity on terms. Buying outright (cash or personal loan): you own the car, no mileage limits, sell whenever — but you bear all depreciation. Hire Purchase (HP): monthly payments with ownership at the end — buying on instalments. PCP (Personal Contract Purchase): low monthly payments, a final “balloon” payment to own, or hand back — the UK’s most popular finance method, effectively a lease with a purchase option. PCH (Personal Contract Hire, “leasing”): fixed monthly payments, hand the car back at the end, never own — pure usage.
The practical spectrum runs from ownership (cash/HP) through hybrid (PCP) to pure usage (PCH). Monthly costs typically rise along that spectrum for equivalent cars — leasing looks cheap monthly because you are not paying for ownership — but total cost comparisons must include deposits, final payments, mileage charges and what (if anything) you own at the end. The Financial Conduct Authority on car finance regulates these products, and MoneyHelper’s car buying and leasing guidance explains them impartially.
How often should you revisit the decision?
Review at every natural decision point: when your current finance ends (PCP/PCH term end forces the question), when your circumstances change (mileage shifts, family grows, job changes), when the market shifts significantly (interest rate moves, EV transition affecting residuals), and at least every two to three years as a matter of routine. The answer that was right at 25 is rarely right at 40.
More specifically: reassess whenever your annual mileage changes by 30 per cent or more (mileage is the single biggest variable — leases penalise excess miles heavily, while ownership absorbs them), when your cash position changes (a windfall or tight period alters the deposit equation), and when your time horizon changes (keeping a car 8+ years favours buying; 2-3 year cycles favour leasing). Do not set-and-forget: drivers who leased happily at low mileage then changed jobs often bleed thousands in excess mileage charges they never re-examined. The commercial world faces the same calculus — see buying versus leasing a van for business.
The maths: total cost of ownership
Compare properly: total cost = all payments (deposit + monthlies × term + final/balloon if buying) + insurance + tax + servicing + estimated repairs − resale value (if buying). Leasing has no resale value but lower payments; buying has higher payments but an asset at the end. The honest comparison is cost per year of motoring, not monthly payment.
Worked intuition: a £25,000 car bought outright and kept 6 years, sold for £9,000, with £4,000 in servicing/repairs — roughly £20,000 total, or £3,300/year before insurance/tax. Leased at £350/month for 6 years (two 3-year terms): £25,200 with no asset, but newer cars, warranty coverage and no MOT/repair surprises. The buyer “wins” financially if the car is reliable and kept long; the leaser wins on hassle, predictability and always driving a new car. Neither is universally superior — the winner depends on reliability luck, ownership duration and how you value convenience. Always get multiple quotes; the insurance a home-based business needs illustrates how protection costs factor into vehicle decisions for business users.
Who should lease, who should buy
Leasing (PCH) suits: drivers who want a new car every 2-3 years, those valuing predictable costs and warranty coverage, business users (tax advantages), high-depreciation segments where ownership bleeds value, and anyone who dislikes selling cars. It punishes: high-mileage drivers (excess charges), those who kerb alloys and scuff bumpers (damage charges), and the cash-conscious (it is the most expensive way to motor long-term).
Buying (cash/HP) suits: long-term keepers (8+ years), low-mileage drivers, those who modify cars, the debt-averse, and anyone with cash earning less than finance costs. PCP suits the middle ground: lower monthlies than HP with flexibility at term end — but understand the balloon payment reality (you must pay, refinance or hand back; many are surprised). The key insight: match the method to your actual behaviour, not your aspirational self. If you have never kept a car more than three years, stop telling yourself you will “this time” and lease honestly.
The traps in the fine print
Read before signing. Excess mileage charges (typically 5-15p/mile — 5,000 excess miles at 10p is £500), damage and wear-and-tear standards (lease companies charge for anything beyond “fair wear” — photograph everything at handover), early termination penalties (exiting PCP/PCH early is expensive; understand the 50 per cent rule under the Consumer Credit Act), and balloon payment realities (PCP’s guaranteed future value is only guaranteed if the car meets condition and mileage terms).
Also: GAP insurance (covers the shortfall if a leased/financed car is written off — often worth it), interest rate comparisons (compare APRs like-for-like, and remember dealer finance is negotiable), and the deposit question (large deposits lower monthlies but are at risk if the car is written off early — GAP insurance mitigates). The FCA’s recent scrutiny of motor finance commission arrangements means the market is cleaner than it was — but diligence remains your responsibility.
Conclusion
Revisit the lease-versus-buy decision at every finance term end, every major life change, and at least every two to three years. Calculate total cost per year honestly, match the method to your real behaviour (not aspirations), and read the fine print on mileage, damage and termination. There is no universally right answer — only the right answer for your mileage, your horizon and your finances, right now.
Frequently Asked Questions
Is leasing a car cheaper than buying?
Monthly payments are usually lower, but long-term it is typically more expensive — you never own an asset. Leasing wins on predictability and newness; buying wins on long-term cost for keepers.
What happens at the end of a PCP deal?
Three options: pay the balloon payment and keep the car, part-exchange it (using any equity as deposit), or hand it back (subject to mileage and condition terms). Decide before the term ends.
How are excess mileage charges calculated?
Typically 5-15p per mile over your contracted allowance. Estimate mileage honestly upfront — it is far cheaper to contract for realistic miles than to pay excess charges.
Can I end a lease early?
Usually yes, but expensively — early termination fees apply, though the Consumer Credit Act’s 50% rule caps liability on regulated agreements once you have paid half the total. Check your contract.
Is PCP a good deal?
It suits drivers wanting low monthlies with end-of-term flexibility. Compare its total cost against HP and PCH for your situation — the “best” deal depends on whether you will buy, swap or return.
Does leasing affect my credit score?
Yes — lease and finance agreements appear on credit files, and missed payments damage your score like any credit. Successful completion with clean payments builds positive history.
