MOT Checkup vs CarCostCheck: Free MOT History Check Compared

Both have strong free tiers. MOT Checkup leads on MOT depth and AI common-faults; CarCostCheck leads on running cost and reliability score.

MOT Checkup is the better tool for a deep free MOT history check while CarCostCheck is the better tool for ownership costs, because MOT Checkup centres on the DVSA MOT timeline plus AI common-faults and a free stolen check, whereas CarCostCheck builds its free tier around fuel cost projections, road tax estimates and a reliability score with a paid upgrade from around £4.99 for extras.

TL;DR

  • MOT Checkup: free, MOT-history-first, AI common-faults, free stolen check.
  • CarCostCheck: free, ownership-cost-first, reliability score, paid tier from around £4.99.
  • The two complement each other rather than duplicate.
  • Use MOT Checkup before viewing a specific car; use CarCostCheck when shortlisting models.
  • Neither replaces a paid HPI-style report for finance or write-off data.

The honest summary

CarCostCheck is the closest free competitor on quality of the free tier, with one of the best running-cost views in the UK market. MOT Checkup is not trying to be a CarCostCheck — it is trying to be the best free MOT history checker with AI context and a stolen check built in. Use the right tool for the right question, and a paid HPI-style report on top when finance or write-off matters.

Frequently asked questions

Is CarCostCheck free?
CarCostCheck has a strong free tier including running-cost estimates, fuel cost projections and a reliability score, with a paid premium upgrade priced from around £4.99 for additional history data. MOT Checkup is fully free for MOT history, mileage, advisories, AI common-faults and a stolen-vehicle check, with no upgrade.
Which one shows MOT history in more depth?
MOT Checkup. The full DVSA timeline is the core product, with mileage at every test, advisory list, defect categorisation and AI common-faults summarised by make and model. CarCostCheck shows MOT data but its strongest free feature is running-cost analysis, not deep MOT history.
Where does CarCostCheck win?
Running costs. CarCostCheck's free tier includes fuel cost projections, road tax estimates, insurance grouping and a reliability score that draws on owner-survey data. If your question is what owning this car will cost over three years, CarCostCheck is the better starting point. For MOT history depth, MOT Checkup leads.
Do they overlap on common-faults coverage?
Both surface model-level fault information, but in different ways. CarCostCheck draws on owner-reported reliability surveys; MOT Checkup uses AI to summarise DVSA failure patterns by make and model. The two are complementary rather than duplicating each other — a thorough buyer can read both.
When should I use CarCostCheck instead?
If you are choosing between candidate cars and want running costs, fuel projections and a reliability score in one place, CarCostCheck is genuinely strong. For the MOT and mileage angle on a specific registration you are about to view, MOT Checkup gives you that with a free stolen check on top.
Can I use both services together for a complete picture?
That's the most thorough approach for a few minutes' work. Use CarCostCheck to model 3-year ownership cost, fuel and tax projections before you shortlist. Once you've picked a specific candidate, run that registration through MOT Checkup for the full DVSA history, mileage trail, advisory pattern, and stolen-vehicle status. Different questions, different tools — both free.
