How Much Is My Car Worth? UK Valuation Guide (2026)

Short answer: Start with a free car valuation by reg for an instant estimated value range, and enter your registration plate on CarCostCheck for a free condition report (MOT history, reliability, running costs). Then add the £2.99 valuation for the local dealer value from live UK listings. You will see that figure and a private sale price range, plus days-to-sell estimates where listings allow. The history check and valuation for £6.99 includes both, and buyers will want to see the history.

CarCostCheck makes its money by selling you the data (£2.99), not from buying your car or getting you to list it. The valuation is based on live market data, not what someone wants to pay or charge you.

What the CarCostCheck Valuation Shows

• Private sale range: What a private buyer would realistically pay for your car
• Local dealer value: What dealers near you are asking for similar cars, from live dealer listings (it needs your postcode, and enough similar cars for sale nearby)
• Days to sell: How long similar cars typically take to sell in your area
• Years left on the road: How long the car is likely to keep going
• Estimated insurance group: Our own estimate, with example quotes

It does not give a part-exchange figure. If you are trading in, get a quote from the dealer or a buying service too, and expect it to sit below the private sale range.

What Affects Your Car's Value

The Big Five (in order of impact)

Factor	Impact on Value	How to Check
Age and mileage	Largest single factor	CarCostCheck free report
Service history	Full history adds 10-15% vs none	Physical inspection
MOT history	Clean record adds value, failures reduce it	CarCostCheck free report
Number of owners	Fewer is better (1-2 is ideal)	CarCostCheck premium report
Condition and spec	Alloys, leather, sat nav, colour all matter	Physical assessment

Things That Reduce Value More Than You Think

• Unpopular colours: Brown, green, and bright yellow cars sell for 5-10% less than black, white, grey, or silver equivalents.
• High mileage: Over 100,000 miles drops value significantly, even if the car is mechanically sound.
• MOT advisories: Current advisories reduce value because the buyer will factor in repair costs. Fix cheap advisories before selling.
• Missing service stamps: Even one missing stamp breaks the chain and reduces buyer confidence.
• Previous write-off: A Cat N or Cat S marker permanently reduces value by 20-50%. You cannot remove it.

Things That Increase Value

• Full dealer service history: Every stamp from the franchised dealer network. This is worth 10-15% on its own.
• Low mileage for age: Under 8,000 miles per year is considered low mileage.
• Desirable spec: Automatic gearbox, leather seats, sat nav, parking sensors, and alloy wheels all add value.
• Long MOT: A freshly passed MOT with no advisories is a selling point. Consider getting an MOT before listing if yours is due soon.
• Two keys: A replacement key costs £200-500, so having both adds value.

How to Maximise Your Car's Value

1. Run a free CarCostCheck report to see your car through a buyer's eyes. Note any advisories or issues.
2. Fix cheap issues: Advisory items like worn wipers (£15), low tyres (£60 each), or a missing bulb (£5) are cheap to fix but make the car look poorly maintained.
3. Get the £2.99 valuation to set the right asking price. Price 5-10% above the private sale value to leave negotiation room.
4. Clean thoroughly: A professionally valeted car sells for measurably more. Spend £50-100 on a full valet.
5. Photograph well: Clean car, natural daylight, clear background. Show the dashboard, boot, engine bay, and any features.
6. Have the CarCostCheck report ready: Showing buyers a clean history report builds trust and justifies your asking price.

What Makes CarCostCheck Different

CarCostCheck is not just a cheaper version of HPI. As well as the history check, it helps you judge whether a car will be a good one to own. Here is what you get that HPI does not offer at any price:

• Market valuation from £2.99, based on live UK dealer listings. See the local dealer value for your car and how quickly similar cars sell near you.
• Estimated vehicle lifespan: An estimate of how many years the car has left on UK roads and the probability of it still being on the road in 12 months.
• Insurance costs by age: See estimated annual premiums for drivers aged 20, 30, 40, and 50. Budget before you buy.
• Running cost breakdown: Annual fuel, road tax, MOT, predicted repairs, and total cost per month. All calculated for this specific car.
• Reliability score (0-100): one number based on the car's MOT record, including its pass rate, recent failures, advisory trend and mileage. Free.
• Common faults: the problems that keep coming up in the car's own MOT history. Free.
• 12 free checks: Full MOT history, mileage verification, reliability score, running costs, fuel costs, red flag alerts, common faults, recall check, ULEZ compliance, tax and MOT status, and more. All before you pay a penny.

The premium history check (£4.99) uses the same Experian database as HPI, AA, and RAC. You get the same core checks: stolen, outstanding finance and write-off. The complete bundle (history + valuation) is £6.99, still 65% cheaper than HPI's basic check.
