Buying vs Leasing a Car: Every UK Route Compared

At a Glance

*100% deductible if CO2 ≤ 50g/km; otherwise a 15% disallowance applies.

1. Outright Purchase (Cash)

Paying cash for a car is the simplest route — you own the asset on day one and owe no one anything thereafter. For a £30,000 car kept four years and sold for around £15,000, the net cost is roughly £15,000 of depreciation plus running costs (tax, insurance, fuel, servicing).

The big hidden cost is the opportunity cost of locking up £30,000 in a depreciating asset. At 5% annual return that £30,000 could have earned £1,500/year of investment growth — over four years that is £6,000 of forgone returns. Outright purchase still usually wins on long horizons (8+ years) because you avoid all financing interest, but on shorter holds it is not always the cheapest option net of opportunity cost.

For sole traders, capital allowances of 18% per year (6% for cars over 50g/km from April 2025; 100% First Year Allowance for new zero-emission cars) provide tax relief spread across multiple years. Limited companies get the same allowances but face the additional BIK charge if any private use occurs.

2. Hire Purchase (HP)

HP is the simplest form of car finance: a deposit (typically 10-20% of the car's price), then a fixed number of equal monthly payments over 24-60 months. The lender holds title to the vehicle until the final payment, at which point ownership transfers to you. There is no balloon payment — the loan fully amortises over the term.

For a £30,000 car with £3,000 deposit at 9% APR over 48 months, monthly payments are roughly £670 and total cost is around £35,400 — about £5,400 of interest on top of the £30,000 list price. You own a 4-year-old car worth around £15,000 at the end, giving a net cost of around £20,400 over the period.

HP's big regulatory protection is the Consumer Credit Act 1974 right of voluntary termination. Once you have paid 50% or more of the total amount payable (deposit plus instalments plus interest plus fees), you can return the car and walk away with no further liability. This is genuinely useful when financial circumstances change and you do not want to be forced to a private sale below the outstanding finance.

3. Personal Contract Purchase (PCP)

PCP is the dominant car-finance product in the UK — about 80% of new private car sales in 2024. The structure: deposit + monthly payments + a balloon payment at the end equal to the lender's Guaranteed Future Value (GFV). The monthly payments only cover the depreciation between today and the GFV, plus interest, so they are materially lower than HP for the same car.

For a £30,000 car on PCP at 9% APR with £3,000 deposit and a £12,000 GFV after 48 months, monthly payments are roughly £370. At the end you have three options: pay the £12,000 balloon and keep the car; hand it back (subject to mileage and fair wear and tear); or use any equity above the GFV as deposit on a new PCP. Total cash spent over 4 years if you hand back: £3,000 + £370 × 48 = £20,760 — roughly equivalent to the depreciation plus interest, and £0 if you walk away clean.

The trap is mileage. A typical PCP fixes 10,000 miles a year; exceeding it triggers 6-15p per excess mile. The fair wear and tear standard at hand-back is also stricter than most owners realise — dealers regularly invoice £300-£1,500 of damage charges on return. PCP also benefits from the same 50% voluntary termination right under the CCA 1974 as HP, providing an exit option if circumstances change.

4. Personal Contract Hire (PCH)

PCH is pure leasing: you never own the vehicle, you simply rent it for an agreed term with an agreed mileage. At the end you hand it back with nothing further to pay (subject to mileage and fair wear and tear) and move on to the next car. There is no deposit option to buy at the end — PCH is one-way only.

For a £30,000 car on a 4-year PCH with 10,000 miles/year, typical monthly payments are around £350 with a 3-6 month initial rental of £1,050-£2,100. Total cost over 4 years: roughly £18,000-£19,000 — the cheapest of the financing options for an equivalent car, because the lender benefits from VAT recovery and bulk purchase discounts that partially offset their depreciation risk.

PCH has no statutory voluntary termination right — early exit charges typically equal 50-100% of remaining contracted payments, making mid-contract escape expensive. This is the single biggest practical drawback. For people with stable circumstances and predictable mileage, PCH is often the cheapest way to drive a new car; for those facing potential life upheaval (redundancy, divorce, relocation), HP or PCP with their CCA termination right offer more flexibility.

5. Business Contract Hire (BCH)

BCH is the business equivalent of PCH, taken in the name of a limited company, partnership or sole-trader business. The mechanics are identical to PCH — fixed monthly payments, agreed mileage, no end-of-term ownership option — but the tax treatment differs significantly.

For a sole trader, BCH payments are 100% deductible for Income Tax purposes if the vehicle's CO2 emissions are 50g/km or lower (i.e. EVs and ultra-low-emission plug-in hybrids). For petrol and diesel cars over 50g/km, a 15% disallowance applies — only 85% of the lease payment is deductible. Limited companies get the same treatment for Corporation Tax. The VAT position is also better than outright purchase: 50% of VAT on the lease is recoverable for cars used both privately and for business, or 100% for pure business pool cars.

BCH typically also bundles maintenance, road tax and breakdown cover, simplifying cashflow planning. For a sole trader, BCH on a £30,000 EV at £350/month over 4 years attracts effective tax relief of about £4,032 at the 20% basic rate or £6,720 at higher rate — bringing the net post-tax cost below outright purchase.

6. Salary Sacrifice EV

Salary sacrifice for an EV is the most tax-efficient way for an employee to acquire a car in 2025/26. You give up an agreed amount of gross salary in exchange for an all-inclusive EV lease bundle provided by your employer. The salary swap reduces both Income Tax and employee National Insurance, while BIK on the EV is just 3% in 2025/26.

For a £30,000 EV at £450/month gross salary sacrifice, a higher-rate (40%) taxpayer saves 40% Income Tax + 2% NI = 42% of the gross figure = £189/month. Add back BIK of roughly £30/month (£30,000 × 3% × 40% / 12) and net cost is about £291/month — versus £450 if they leased the same car personally. Over 4 years that is a saving of around £7,600.

Salary sacrifice bundles include the car, fully comprehensive insurance, servicing, maintenance, tyres, breakdown cover and a home charger installation — making the monthly figure genuinely all-in. The biggest restrictions: it works tax-efficiently only for EVs (BIK on petrol cars erodes the advantage), it requires an employer who has set up a scheme, and leaving employment mid-lease usually triggers an exit charge (mitigated by "protection" insurance offered by most scheme providers).

Worked Example: £30,000 Car Over 4 Years

Putting it all together for the same £30,000 car driven 10,000 miles per year for four years, here is the comparison on a household cost basis (excluding fuel and insurance where not bundled):

Outright purchase wins on absolute cost for ICE vehicles, but ties up the most capital. Salary sacrifice EV beats every other option for higher-rate taxpayers with access to a scheme — and that gap widens further if you include the insurance and maintenance that salary sacrifice bundles in but the other routes do not.

Voluntary Termination — The Hidden Right

Section 99 of the Consumer Credit Act 1974 gives anyone on HP or PCP the right to end the agreement early, return the car and walk away — provided they have paid (or are willing to top up to) 50% of the total amount payable. The right is unconditional: the lender cannot refuse, the credit file impact is usually neutral (recorded as terminated, not defaulted), and there is no obligation to find a buyer.

This is one of the strongest consumer protections in UK finance law. It does not apply to PCH or business contract hire because those are rental agreements, not credit. The absence of voluntary termination is the single most important risk consideration for anyone signing a 3-4 year lease — if your life circumstances change, the exit is entirely on commercial terms set by the leasing company, typically expensive.

Who Bears Depreciation Risk?

Cars depreciate roughly 50-60% over their first four years in normal conditions. On a £30,000 car, that is £15,000-£18,000 of value loss — by far the biggest single cost of ownership, dwarfing fuel and tax. Who bears that risk is the most economically meaningful difference between finance routes.

Outright purchase and HP transfer all depreciation risk to you — if the used-car market crashes (as it almost did in 2023 for EVs), your loss is unbounded. PCP transfers tail-end risk to the lender via the Guaranteed Future Value: if real residuals fall below the GFV, the lender absorbs the loss. PCH and salary sacrifice transfer all depreciation risk to the leasing company — you pay a fixed monthly rate and walk away cleanly at the end. The 2022-2024 EV residual collapse is what made many lease providers withdraw cheap EV deals; that risk-bearing is real money.
