Beyond price: The complete car lease comparison checklist

The complete car lease comparison checklist

TL;DR: What should I look for when comparing car lease deals?

The monthly payment is the first thing you’ll notice when comparing car lease deals – but it’s rarely the whole story. Initial payment structure, mileage allowance, contract length, insurance costs, and end-of-contract charges all affect the true value of a deal.

Use this guide to work through every factor that matters before you sign, and you’ll be far better placed to tell a genuinely good deal from one that only looks good on the surface.

That tempting monthly payment figure – you’ve spotted it, and now you can’t stop thinking about it

We get it. When you’re comparing car lease deals, the monthly payment is the first thing that catches your eye. It’s bold, it’s clear, and it’s what every car lease broker and comparison site plasters across their listings.

But focusing solely on the monthly payment is like judging a book by its cover.

You might end up with a real page-turner, or you might find yourself stuck with something that doesn’t quite live up to expectations.

The good news?

By the end of this guide, you’ll know exactly how to spot a dud deal from a mile away. Whether you’re comparing petrol, hybrid, or electric car lease deals, the same rules apply – and the full picture matters more than the headline figure.

So, from the obvious factors to the sneaky costs you might not be expecting, let’s get into it.

Initial payment

The initial payment – usually called the initial rental – is your upfront cost at the start of your lease.

Unlike a traditional deposit, it isn’t refundable, and it doesn’t act as security against damage; it’s simply a larger payment made at the outset that reduces the total on your remaining monthly payments.

You’ll often see deals advertised as 1+23, 3+23, 6+23, or 9+23 (the first number being the initial payment, the second being the number of monthly payments that follow).

The initial rental is expressed as a multiple of your monthly payment. So, the higher the multiple, the more you pay upfront.

It’s worth noting that you don’t have to make a large upfront payment. You also have the option to do a no-deposit deal. In practice, this means your initial payment is equal to one month’s payment.

There’s no larger sum to find upfront, and your payments stay consistent throughout the contract.

Here’s how the different structures compare on a car with a monthly payment of £300:

• 1+35: You pay £300 upfront, then £300 for 35 months
• 3+35: You pay £900 upfront, then £275 per month for 35 months
• 6+35: You pay £1,800 upfront, then £255 per month for 35 months
• 9+35: You pay £2,700 upfront, then £240 per month for 35 months

Ultimately, it comes down to cash flow.

A higher initial payment lowers your monthly outgoings. But it’s a larger sum to find upfront, and it doesn’t get returned at the end of your contract.

Annual mileage

Mileage affects the price of your lease more than most people realise, so it’s worth getting it right before you commit.

It matters because mileage is one of the key ways finance providers measure depreciation. The more miles a car does, the lower its value at the end of the contract.

When your lease ends, your finance provider will sell the car on, and your agreed mileage is a big part of how they calculated what it would be worth.

If you go over your agreed mileage, you’ll be charged an excess mileage fee to account for the additional depreciation.

How to calculate your real mileage

According to the Department for Transport’s National Travel Survey (2025), the average UK driver covers around 7,100 miles a year. If you’re unsure where to start, that’s a useful baseline.

But your own habits matter more than any average.

To work out a realistic figure:

• Check your MOT certificates if you’ve been driving for a few years – they’ll show your mileage at each test
• Calculate how many miles you cover in a typical month and multiply by 12
• Account for seasonal variation – some months will be higher than others
• Add a 5% buffer for unplanned journeys

It’s also worth remembering that mileage is pooled across your contract.

On a three-year lease at 10,000 miles per annum, your total allowance is 30,000 miles. If you do 8,000 one year and 12,000 the next, you’re fine as long as the total doesn’t exceed 30,000 by the end of your contract.

What happens if you go over

Excess mileage charges typically range from 7p-20p per mile, though they can be as low as 5p or as high as 30p depending on your provider.

If you go over your mileage by 1,000 miles, that’s a fee between £50 to £200. It pays to get your mileage estimate right from the start.

If you think you’re approaching your limit mid-contract, contact your finance provider to discuss your options. Not every provider will let you amend your contract mid-lease, but if you can, it’s often cheaper than paying excess charges at the end.

Contract length

24, 36, or 48 months – each has its pros and cons, and the right choice depends on your circumstances.

Two-year contracts give you the flexibility to swap cars more frequently, which suits drivers who like being in the latest model or want to keep their options open.

A shorter contract isn’t necessarily a lower-risk one.

Three-year contracts are the most popular option and generally offer the most competitive monthly payments.

The car also won’t typically need an MOT during the contract term, unless it’s pre-registered.

Four-year contracts offer more stability, but a longer contract doesn’t automatically mean lower monthly payments: It depends on the terms available and the residual value of the car.

Just bear in mind that if your circumstances change and you need to exit early, termination charges can be significant.

A note for electric car lessees

Contract length is worth thinking about carefully if you’re comparing electric car (EV) lease deals.

EV tech is moving quickly.

Battery range, charging speeds, and available models are all improving year on year. A two- or three-year contract may mean you’re better placed to upgrade to a newer, more capable model sooner.

On the other hand, longer contracts can offer more payment stability at a time when EV pricing is still settling.

There’s no single right answer, but it’s a factor that’s more relevant for EVs than it is for petrol or diesel.

Depreciation

Your monthly payment is determined by the car’s residual value (RV), a pre-agreed figure that your finance provider believes the car will be worth at the end of your lease term.

To arrive at this figure, they take into account expected depreciation, historical pricing data, and your agreed mileage.

You’re only ever paying for the depreciation that occurs during your contract, not the full value of the car. That’s one of the core financial advantages of leasing over buying.

Electric vs petrol depreciation

EV depreciation has historically been harder to predict than petrol or diesel depreciation, largely due to rapidly evolving technology, limited used market data, and early uncertainty around battery performance and demand.

The picture in 2025 became more settled.

According to Cox Automotive data (November 2025), average EV depreciation sits at 38-42% over three years, compared to 35-40% for petrol vehicles.

The gap has narrowed significantly as battery transparency improves, used EV supply grows, and buyer confidence increases. Though, EV depreciation still shows more variation by model than petrol equivalents, particularly between newer long-range models and older, shorter-range vehicles.

If you’re leasing, the key point is this: Whichever fuel type you choose, your residual value is locked in before your contract begins.

You won’t be exposed to unexpected shifts in the used car market, and you won’t have to worry about selling the car when your term ends. Hand the keys back, and walk away.

Delivery timing and availability

In stock vs factory order

In stock means the car has already been manufactured and is ready to lease.

Some are already at UK dealerships being prepared for delivery, while others are in transit. Because they aren’t being built to order, you won’t face a long wait. Once finance is approved, contracts are signed, and a delivery date is agreed, your new car could be with you in as little as a week or two.

Factory orders are different.

The car hasn’t been built yet – it’s configured to your specification, with any optional extras you’ve chosen. That means waiting for a build slot to be assigned, production to complete, shipping to the UK, and arrival at the dealership.

Depending on the manufacturer and model, that wait can range from a few weeks to several months.

Sometimes an in-stock car will already have been registered before it’s been sold; this is known as a pre-registered vehicle. This can work in your favour, as the earlier registration often unlocks a cheaper finance rate, meaning you could access a deal that wouldn’t otherwise be available.

Why lead times are worth factoring in

Factory order lead times can be affected by factors outside anyone’s control – global supply chain pressures, manufacturing capacity, and parts availability have all caused delays in recent years.

While these issues aren’t always predictable, they’re worth bearing in mind if you’re working to a deadline, such as the end of a current lease or change in personal circumstances.

If timing matters, in-stock deals are the safer bet.

Insurance group ratings

This is where a cheaper lease could end up costing you more overall.

Every car is assigned an insurance group from 1 to 50. The higher the number, the higher the premium you’re likely to pay. A car with a lower monthly payment but a higher insurance group could end up costing you significantly more than a slightly pricier lease with a lower rating.

Factor in your age, postcode, and driving history, and the difference can be substantial.

Before you commit to a deal, run a provisional quote through a comparison site to get a realistic sense of your insurance costs. Your total monthly outgoings are what really matter, not just the lease payment in isolation.

Insuring an electric lease car

It’s worth knowing that EVs currently cost more to insure than their petrol or diesel equivalents.

According to MoneySuperMarket data, the average comprehensive insurance premium is £497 for petrol cars and £572 for electric – a difference of £75 per year.

Higher repair costs and battery replacement expenses are the primary reason insurers charge more for EVs.

That said, your personal circumstances will have a far greater bearing on your premium than your fuel type alone. Age, location, job title, and insurance group all play a significant role.

The bigger picture on EV running costs

While electric cars attract higher insurance premiums, they’re generally cheaper to run and maintain overall – especially if you’re able to charge at home overnight.

Research from the Energy and Climate Intelligence Unit (ECIU) in 2023 found that petrol cars cost around £700 more to run per year than their electric equivalents. Over a car’s lifetime, this cost can add up to as much as £10,000 more than an electric car.

So, while the monthly lease payment and insurance premium are important comparison points, they’re only part of the equation.

For many drivers, the lower day-to-day running costs of an electric car more than offset the higher insurance premium.

If you’re comparing electric car lease deals to petrol or diesel cars, it’s worth looking at the full monthly cost – lease payment, insurance, and fuel or charging – to get a true like-for-like picture.

Other fees

Transparency around fees is one of the most important things to look for when comparing lease deals and choosing a broker.

Here’s a breakdown of the charges you might encounter beyond your monthly payment and initial payment.

Arrangement fee

A one-off fee that we charge to cover the work involved in sourcing and securing your lease deal.

We use a variable structure for our arrangement fee – simpler deals attract a lower fee, more complex ones are priced accordingly – but you’ll always know what you’re paying before you commit.

Documentation fee

If you want to take your lease car outside the UK, you’ll need a VE103 or VE103B document.

Your finance provider may charge a small fee for these – worth factoring in if you’re planning to drive abroad during your contract.

Amendment fees

Any changes to your contract mid-term – such as adjusting your mileage allowance – might affect your monthly payments.

It’s worth knowing that mileage is linked to residual value, and there may have been a discount applied to your original mileage choice.

Reducing your mileage mid-contract won’t always result in a lower monthly payment as a result, and not every finance provider will allow you to change your agreement mid-term.

End-of-contract charges

Any damage beyond fair wear and tear, or mileage over your agreed allowance, might result in additional charges when you return the car.

Early termination

Taking out a lease doesn’t mean you’re locked in with no way out.

You do have the right to end your contract early, though charges will typically apply. Depending on your finance provider, this is often calculated as 50% of your remaining monthly payments.

For example, if your monthly payment is £300 and you have 12 months left on your contract, an early termination charge could be in the region of £1,800.

If you need to end your lease early, contact your finance provider to discuss your options – the process and charges will vary from provider to provider.

Fair wear and tear

The British Vehicle Rental and Leasing Association (BVRLA) Fair Wear and Tear Guide sets an industry-wide standard for the condition a lease car should be returned in at the end of the contract.

It covers every aspect of wear and tear that can occur under normal usage, accounting for natural deterioration relative to the car’s age and mileage.

The guidelines cover windows, windscreens and lights, interior upholstery, exterior paintwork, wheels, tyres, and trim, plus mechanical condition and documentation.

Anything beyond what the BVRLA defines as acceptable fair wear and tear may result in an end-of-contract charge.

How to avoid charges

• Assess your car’s condition at least 10 weeks before your return date – this gives you enough time to arrange any necessary repairs before the contract ends
• Be objective when assessing condition and check in good lighting
• Make sure the car is clean and dry before inspecting
• If repairs are needed, arrange them yourself rather than leaving them to your finance provider

Maintenance packages

A maintenance package is an optional add-on available alongside your lease, with a fixed monthly payment covering the cost of keeping your vehicle in good condition throughout the contract.

It can be a useful way to budget for servicing and repairs without unexpected costs cropping up along the way.

What’s typically included:

• Maintenance and repairs
• All scheduled servicing
• Tyre replacements due to fair wear and tear
• Puncture cover (excluding sidewall damage)
• Roadside tyre assistance (where possible)
• MOTs
• Replacement wear and tear items such as wiper blades, batteries, exhausts, and brakes
• Breakdown assistance
• Warranty assistance

What’s typically not covered:

• Glass and windscreens
• Vehicle bodywork damage
• Damage resulting from a collision
• Items damaged through driver abuse
• Damage resulting from negligence
• Shoulder and sidewall tyre damage
• Misfuelling
• Lost or damaged locking wheel nuts, keys, compressors, and charging leads
• Flat batteries (unless due to a fault covered under warranty)

The 1.5 rule: How to sense-check a lease deal

The 1.5 rule is an informal industry benchmark suggesting that if your monthly payment is less than or equal to 1.5% of the car’s list price, the deal represents good value.

For example, on a car with a list price of £30,000, 1.5% works out at £450.

If your monthly payment is £450 or less, the deal would be considered cost-effective under the 1.5 rule.

It’s a useful starting point, but it’s worth remembering what it doesn’t account for – mileage limits, initial payment structure, insurance costs, and additional fees can all affect the true value of a deal.

Use the 1.5 rule as a quick sense-check, not a substitute for looking at the full picture.

Frequently asked questions

What should I look for when comparing car lease deals?

Look beyond the monthly payment and consider the total cost, mileage allowances, contract terms, initial payment, insurance costs, and any additional fees.

The cheapest monthly payment isn’t necessarily the best value – always look at the full picture before you commit.

How do I know if a lease deal is good value?

Use the 1.5 rule as a starting point – your monthly payment should be 1.5% or less of the car’s list price.

But you’ll also want to factor in the whole life cost, including insurance, fuel or charging, maintenance, and any additional fees. The 1.5 rule is a useful sense-check, but not a guarantee.

What hidden costs should I look out for in leasing?

Arrangement fees, documentation charges, amendment fees during the contract, excess mileage charges, and end-of-contract damage charges beyond fair wear and tear are all costs that can arise outside of your monthly payment and initial rental.

A good broker will be transparent about all these upfront.

Why isn’t the cheapest lease deal always the best?

The cheapest monthly payment can come with restrictive terms, higher insurance costs, a larger initial payment, or additional fees that make the total cost higher than a seemingly more expensive alternative.

Always compare like-for-like terms before making a decision.

Is leasing an electric car different to leasing a petrol car?

The process is the same, but there are a few extra factors worth considering.

Electric cars currently attract higher insurance premiums than petrol equivalents, though they’re generally cheaper to run day to day. EV depreciation is also stabilising – residual values are becoming more predictable, which is reflected in more competitive monthly payments.

If you’re comparing electric car lease deals, factor in insurance, charging costs, and contract length alongside the monthly payment for a true picture.
