Your PCP mileage limit is too low: what going over could cost and how to cut the damage
If your PCP mileage allowance looked fine when you signed, but your life has changed since then, you are not alone. A longer commute, a house move, school runs, or a job switch can turn a comfortable mileage plan into an expensive problem.
The important point is this: going over your mileage limit does not usually matter because you have somehow broken the car finance. It matters because the car may be worth less at the end of the agreement than the finance company expected when it set your optional final payment.
That is why the smartest move is to price the problem early, then compare your exit routes before the last month of the agreement. Waiting until handback day is how a manageable charge turns into a nasty surprise.
What the mileage limit on a PCP actually does
On a Personal Contract Purchase agreement, the lender estimates what the car should be worth at the end of the term. Your agreed mileage is part of that calculation.
If you return the car with more miles than agreed, the lender can charge excess mileage according to the contract. Close Brothers Motor Finance says its agreements with an excess mileage clause charge 10p plus VAT per extra mile if the vehicle goes back, and it explains that the charge exists because extra miles can reduce the vehicle’s end value.
That does not mean every lender charges the same rate. The figure can vary by agreement, vehicle and finance company. The rate that matters is the one written into your own paperwork.
When you usually pay excess mileage, and when you usually do not
This is the bit many drivers get wrong.
You are normally looking at an excess mileage charge if you hand the car back at the end of the PCP and it is over the agreed total. Some lenders can also calculate it on a pro rata basis if the car goes back before the scheduled end.
You do not usually face the same charge if you buy the car and keep it, because the finance company is not taking the vehicle back and trying to sell it on at the forecast value. Close Brothers states this plainly in its consumer guidance.
That distinction matters because it changes the cheapest fix. Sometimes the least painful answer is not to hand the car back at all.
How to estimate the likely bill quickly
Start with three numbers:
- your agreed total mileage
- your current mileage
- your contract’s excess mileage rate
Then use a simple estimate:
| Step | Example |
|---|---|
| Agreed total mileage | 24,000 miles |
| Expected actual mileage at the end | 30,000 miles |
| Excess miles | 6,000 miles |
| Contract rate | 8p per mile |
| Estimated excess mileage charge | £480 |
If your contract rate is 10p plus VAT, the same 6,000-mile overshoot would be £600 plus VAT.
This is only the mileage element. It does not include any separate charges for damage outside fair wear and tear.
Option 1: keep the car if the balloon still makes sense
If you like the car, the condition is good and the optional final payment is manageable, keeping it can be the cleanest way out.
Black Horse says the four standard end-of-PCP options are to keep the vehicle, refinance it, part exchange it or return it. If you keep it, mileage charges tied to handback stop being the main issue because the car is no longer going back to the lender.
This route tends to make most sense when:
- the excess mileage bill would be hefty
- the car has been reliable and you know its history
- the optional final payment is reasonable compared with the car’s real market value
- you would rather avoid paying mileage charges and then starting another agreement immediately
The obvious catch is that you still need to deal with the optional final payment, either from savings or by arranging finance.
Option 2: refinance the final payment
If the handback charge looks painful but paying the balloon in one go is unrealistic, refinancing the final payment can be a middle route.
Black Horse specifically lists refinancing the optional final payment as one of the end-of-agreement options on PCP. Whether it is available, and on what terms, depends on status and the lender’s decision at the time.
This can work well if:
- you want to keep the car
- the car still suits you
- the monthly cost of refinancing is lower than the pain of handing the car back and taking a mileage hit
It is still borrowing, so the question is not just whether you can do it. It is whether the total cost still stacks up once the car is older, worth less and moving closer to post-warranty repair risk.
Option 3: part exchange and use any equity carefully
Part exchange can soften the blow if the car is worth more than the guaranteed future value or settlement figure.
Black Horse’s PCP guidance says you can go to a dealer, agree a part exchange value and have the final optional payment settled before the agreement ends. In practice, this can be useful when the car still has positive equity despite the higher mileage.
The trap is assuming a dealer is magically making the mileage issue disappear. They are not. They are just valuing the whole car in front of them. If the mileage has hurt the value, that will usually show up in the offer.
Still, part exchange can be better than a straight handback if:
- the car has equity
- used market values for your model are still strong
- you need another car anyway
Get more than one valuation. A single dealer offer is not market truth.
Option 4: hand it back and pay the excess mileage charge
Sometimes this is still the sensible route.
If the car’s value has dropped hard, the optional final payment looks poor value, and you do not want to refinance or keep the car, paying the contractual mileage charge and moving on can be the cleanest answer.
What matters is doing the maths before you reach the end.
A £300 to £500 mileage bill can be annoying but manageable. A four-figure bill on a heavily over-mileage car is the point where you should compare every alternative, especially keeping the car or using any equity elsewhere.
Option 5: if the whole agreement no longer works, check voluntary termination properly
If the problem is not just mileage but the agreement itself no longer being affordable or suitable, voluntary termination may enter the conversation.
Under sections 99 and 100 of the Consumer Credit Act 1974, a customer under a regulated hire purchase or conditional sale agreement can end it early by notice, and liability is generally capped at one half of the total amount payable, plus any failure to take reasonable care of the goods. Citizens Advice summarises it in simpler terms: if you end the agreement and have paid less than half the total price, you may still have to pay up to that half; if you have already paid more than half, you usually do not have more instalments to pay.
Black Horse also says customers have a legal right to voluntary termination on regulated agreements and can use it before the agreement ends.
The awkward bit is excess mileage. On a normal end-of-term handback, the contract usually deals with that clearly. On voluntary termination, the legal position is more nuanced. The Act itself talks about the half-rule and reasonable care. It does not create a neat universal rule that every separate excess mileage clause will or will not apply after VT.
So if you are thinking about VT and you are well over mileage, do not guess. Read the agreement carefully, ask for the lender’s position in writing and compare the total likely cost against your other end-of-contract options.

Mileage charges and condition charges are not the same thing
Drivers often focus so hard on the mileage that they forget the second bill.
The British Vehicle Rental and Leasing Association says fair wear and tear is normal deterioration from ordinary use, and not the same thing as damage caused by impacts, neglect or harsh treatment. Its consumer return guidance also says end-of-contract charges can still apply for damage or missing items, while normal wear and tear should not be charged.
That matters because you can be:
- over mileage but otherwise fine on condition
- within mileage but facing condition charges
- unlucky enough to be hit by both
The Motor Ombudsman also notes that wear and tear is generally about normal degradation through use and age, while disputes often turn on what the agreement actually covers.
If your PCP is due back soon, inspect the car early rather than hoping for the best.
How to reduce the damage before the agreement ends
If you already know you are heading over, these are the moves that usually help most:
1. Work out the real over-mileage number now
Do not use a vague guess. Estimate your likely mileage at the actual end date.
2. Check whether the car has equity
A high-mileage car can still have equity if the model is in demand or the guaranteed future value was conservative.
3. Ask the lender about your options early
Close Brothers tells customers worried about mileage to contact it rather than ignore the issue. Not every lender will change the agreement, but early contact is still smarter than late panic.
4. Inspect condition well before return
BVRLA consumer advice recommends appraising a returned vehicle roughly 10 to 12 weeks before handback so there is time to fix anything outside the agreed standard.
5. Compare handback against keeping the car
A lot of drivers compare handback only with changing into another PCP. That is too narrow. Sometimes the cheapest answer is simply to keep the car you already know.

The bottom line
A PCP mileage limit that has gone wrong is usually a maths problem before it becomes a legal one.
If you hand the car back, the excess mileage clause matters. If you keep it, that charge often stops mattering. If the whole agreement no longer works, voluntary termination may be worth examining properly, but not casually.
The winning move is to price every route early, not to assume the finance company will sort it out for you on collection day.
