The Broker Advantage
What your customers are searching for at 11pm
Every month, thousands of UK drivers type "excess mileage calculator" or "what happens if I go over my lease mileage" into Google. They're not idly curious; they're anxious. Return day is looming and they want to know the damage before they hand the keys back.
If your own site doesn't answer those questions, another broker's will, and that broker earns the trust that drives the next deal. The sections below cover the conversations worth surfacing on your own mileage pages, so the calculator doesn't have to do the work alone.
- How the charge is actually calculated, with a worked example they can follow
- Typical pence-per-mile ranges, so they can sense-check their contract
- Whether PCP and contract hire treat excess mileage differently (they do)
- What happens on voluntary termination (the one that catches drivers out)
- VAT treatment, business versus personal
- The levers they can pull if they're already tracking over
Worked Example
How an excess mileage charge is calculated
Here's the maths, walked through the way you'd talk a customer through it on the phone. Take Sarah, a freelance photographer covering shoots across the North West. She signed a 36-month lease on a Tesla Model 3 with 10,000 miles a year; at the time it felt like plenty. Twenty months in, her odometer reads 19,500 and she's starting to worry.
01
Work out her allowed mileage to date
10,000 ÷ 12 = 833 miles per month allowance. Over 20 months that's 16,667 miles allowed.
02
Compare against actual
19,500 actual minus 16,667 allowed gives 2,833 excess miles at this point in the contract. Not yet a bill, but a signal.
03
Project to contract end
Current rate: 19,500 ÷ 20 = 975 miles per month. Across 36 months that projects to 35,100 miles, which is 5,100 over a 30,000 mile contract.
04
Apply the pence-per-mile rate
At 8.5p per mile, 5,100 excess miles = £433.50, plus VAT where applicable.
05
Show her the levers
Drop to 700 miles per month for the final 16 months and Sarah lands inside her allowance. That's the conversation worth having twelve months before return, not the week before it.
Projected bill
£433.50
What Sarah's excess works out at before VAT. Spotted at month 20, it's a number she can still influence. Spotted at month 36, it's just a bill.
Sense Check
Typical pence-per-mile ranges
Rates vary by funder, vehicle and contract, and the agreement itself is always the source of truth. But these are the bands brokers see most often in 2025-26. Useful for sense-checking a customer's quoted rate or setting their expectations before you pull the paperwork.
5p to 9p
Per mile, excluding VAT
Lowest-risk category at return. Small resale volatility, predictable wear.
8p to 14p
Per mile, excluding VAT
Depreciation-sensitive. Rate climbs with residual-value risk.
10p to 18p
Per mile, excluding VAT
Battery wear and volatile resale pricing push rates to the top of the band.
6p to 12p
Per mile, excluding VAT
Usage profile varies widely. Always check the individual contract.
Indicative only, based on published UK contracts in 2025-26. Customer's agreement is always the source of truth.
Contract Types
PCP vs contract hire: different rules, same anxiety
Customers conflate these constantly. Worth drawing the line clearly on your site, because the answer changes the entire end-of-contract experience.
Always payable at return
The funder owns the car and has no route to recover the cost except by billing the driver. No wiggle room, no opt-out.
Only if they hand it back
Buy using the optional final payment and mileage is irrelevant. Part-exchange and the excess usually absorbs into the trade-in value.
Many PCP drivers worry unnecessarily because they don't know the second rule. A paragraph on your site removes the worry, and positions you as the broker who explains it straight.
The One Drivers Miss
Voluntary termination and excess mileage
Under the Consumer Credit Act 1974, a driver who has paid 50% of the total amount payable can voluntarily terminate the agreement and walk away from the remaining finance. It's a genuine consumer protection and, for the right customer, a powerful option.
Excess mileage charges are still payable on VT. The 50% rule covers the finance, not the wear-and-tear obligations.
Drivers reading a headline on a forum sometimes assume VT is a clean break. It isn't, and discovering that after the event is the sort of surprise that torches the relationship with whoever sold them the contract.
If a customer is seriously considering VT, a five-minute mileage projection using the calculator above can turn an ugly end-of-contract into a planned exit. That's broker value customers remember.
Customer FAQs
The questions your customers will ask you
Each of these gets searched thousands of times a month. If your site answers them plainly, you earn authority on pages that drive organic traffic into the top of your funnel.
How much is a typical excess mileage charge?
Rates usually sit between 6p and 15p per mile plus VAT, depending on the funder and vehicle. Premium saloons, SUVs and electric vehicles tend to sit at the higher end. A driver 2,000 miles over allowance at 10p per mile faces a bill of £200 plus VAT.
Do you pay VAT on excess mileage charges?
Yes. Excess mileage charges on business contract hire attract VAT, which business customers can usually reclaim. Personal contract hire customers pay VAT inclusive rates and cannot reclaim the VAT element.
Can excess mileage charges be negotiated at the end of a lease?
Sometimes, at the funder's discretion. If the shortfall is modest and the vehicle is otherwise in good condition, some funders waive or reduce charges. It's worth asking, but brokers should never promise it to a customer as a given.
What happens if a customer goes over their mileage on PCP?
Excess mileage only matters on PCP if the customer hands the car back at the end. If they buy the car using the optional final payment, mileage is irrelevant. If they part-exchange it, the excess is usually absorbed into the trade-in value rather than billed directly.
Can a customer add extra mileage to their contract mid-term?
Most funders allow a mid-contract mileage revision. The uplift rate is almost always lower than the excess mileage rate, so for customers who know they're tracking over, revising the contract is nearly always cheaper than paying excess at return.
Is excess mileage charged per mile or per thousand miles?
Per mile. Contracts quote the rate as pence per mile, for example 8p per mile, applied to every mile over the agreed annual allowance multiplied by the contract term.
Does excess mileage still apply on voluntary termination?
Yes. A driver who voluntarily terminates under the Consumer Credit Act 1974 after paying 50% of the total amount payable can walk away from the remaining finance, but excess mileage charges are still payable. This catches people out and should be flagged during any VT conversation.
How often should a customer check their mileage?
Ideally every six months, and without fail twelve months before contract end. Early action, whether that's a revision, a behavioural change or planning a mid-cycle swap, is almost always cheaper than paying excess at return.
The Bigger Point
Drivers remember the bill, not the car
The brokers who win repeat business aren't the ones with the sharpest pricing on day one. They're the ones whose customers arrive at return day without a surprise. Embedding this calculator is a five-minute job; pairing it with the guidance above turns a tool into a trust asset.
