Can You Increase Your PCP Mileage Allowance Mid-Agreement?

Some lenders will increase a PCP mileage allowance during the term, usually at an extra cost. It is not an automatic right, and a policy for personal contract hire may not apply to PCP from the same provider.

Before requesting a change, decide what you expect to do with the car at the end. An allowance matters directly on a contractual return; if you plan to buy the car, paying extra to alter it may offer little benefit.

Would extra allowance cost less than the expected bill?

Here is an illustrative comparison. Suppose your forecast shows 5,000 excess miles at return, and your contract charges 12p per mile including VAT. The estimated bill would be £600, assuming no higher-rate band or other adjustment applies.

Now suppose the lender offers enough extra allowance to cover that forecast in exchange for £25 more on each of 24 remaining payments plus a £20 fee. The amendment costs £620. On those figures it is £20 more than the forecast excess-mileage charge, although it spreads the cost differently.

If the forecast changes, the comparison changes too. A further 2,000 miles at the same illustrative rate would add £240 to the unamended bill. Check whether those additional miles would also fit inside the proposed new allowance; otherwise the revised agreement could still produce an excess charge.

Do not compare only one month's increase with the entire return invoice. Add every remaining increased payment and fee before deciding.

This comparison needs a realistic forecast. Use the starting odometer reading, today’s dated reading, the total permitted use and your expected remaining journeys. Account for miles already on a used car when supplied; they are not miles you have driven during the agreement.

Some lenders assess the allowance over the full term rather than treating each year as a separate final bill. Stellantis, for example, explains that a higher-mileage year can be offset by lower use in another year within its total contract estimate. Check your own terms rather than assuming that one busy year always means a charge is already due.

The end-of-agreement route changes the decision

Returning the car: the contractual allowance and excess rate normally matter directly. A realistic amendment can reduce uncertainty, but confirm the new maximum reading and any condition charges separately.

Buying the car: ordinary return mileage charges generally do not apply when you pay the required final amount and take ownership. Confirm the position for any charge already raised or unusual agreement wording. Buying involves a much larger financial commitment, so do not choose it solely to avoid a smaller mileage invoice.

Part-exchanging or selling with settlement: mileage can reduce the valuation even where a separate contractual return charge is not applied. Establish whether the dealer is buying and settling the car or arranging its return to the lender. Those routes are different.

Our guides to finance end options and selling a PCP car explain the wider choices.

What to put in the request—and what the quote must show

Give the lender your agreement number, current mileage and expected reading at return. Explain any change of workplace, home or family routine. A deliberately low estimate can leave you needing another adjustment later.

Confirm that an amendment is available at this stage of your contract, including any minimum increase or timing restriction. The PCP structure links expected use with the agreement’s figures.

• Effective date and revised total mileage allowance.
• Number of remaining payments and the increase in each one.
• Administration fee, if any.
• Any change to the optional final payment or excess-mileage rate.
• Whether the new allowance covers the whole term or just the remaining period.

Check whether the allowance is being changed across the whole contract or only for the remaining period. For instance, increasing a stated annual figure by 2,000 does not tell you the revised total unless you know how the lender applies it.

The lender may need further checks for a material amendment. Stellantis says some changes require new credit checks and underwriting under its policy. That does not mean every mileage change with every lender affects a credit file in the same way. Ask before accepting or authorising a new assessment.

Save the lender's accepted variation and verify that the customer portal reflects it. Record mileage periodically and keep the final confirmation for handover. Tell your insurer separately if the expected annual mileage or vehicle use changes under its policy.

If an amendment is unavailable or poor value

Ask for confirmation of the current allowance and rate, then budget from your best forecast. You may be able to reduce optional driving, but do not understate essential work or family journeys just to make the calculation look comfortable.

Changing the car early introduces settlement and valuation questions, including possible negative equity. Obtain those figures before assuming another agreement will be cheaper than an excess-mileage bill.

If the original allowance was entered incorrectly or differs from what you agreed at sale, raise that as a separate complaint with supporting evidence. A request to correct an error is different from voluntarily buying extra mileage after your circumstances changed.
