Searching for an HPI check discount code or a car check voucher? Here is the honest picture: codes are rare, usually expired, and the biggest saving is not a code at all. How to pay the least for a full UK car history check in 2026.
| Provider | Price | Core provenance data | Codes seen in the wild? |
|---|---|---|---|
| Total Car Check (Silver) | £3.99 | Experian | Occasionally, small |
| CarCostCheck | £4.99 | Experian | No code needed, multi-car discount built in |
| MyCarCheck | £4.99 | Experian | Rare |
| AA Car Check | £9.99 | Experian | Member offers only |
| RAC Car Passport | £9.99 | Experian | Member offers only |
| HPI Check | £19.99 | Experian | Almost never, beware the £39/yr auto-subscription |
Full MOT history, mileage check, health score, running costs. No signup needed.
If you are hunting for an HPI check discount code, a Total Car Check voucher, or an AA car check promo, here is the honest answer up front: working public discount codes for UK car checks barely exist in 2026. The voucher sites listing them earn a commission when you click, and most codes are expired or were never real. The good news is you do not need one. Every major UK provider buys its stolen, finance and write-off data from the same Experian feed, and that identical data is sold at prices from £3.99 to £19.99. Choosing the right provider saves you far more than any code ever would.

The pattern is clear: the "discount" you are searching for is really just the gap between providers. Paying £19.99 for data sold elsewhere at £4.99 and then hunting for a 10% code is solving the wrong problem.
Stolen records come from the Police National Computer, finance records from the finance industry register, and write-offs from MIAFTR, all aggregated by Experian and resold to every checker. A £4.99 report reads from the same databases as a £19.99 one. If you want the detail, our cheapest HPI check comparison walks through every provider, and our transparency page documents exactly where CarCostCheck's data comes from.
Most buyers shortlist two or three cars. Checking them together is where a genuine, always-on discount exists:
| Cars checked | CarCostCheck total | Same cars at HPI | You save |
|---|---|---|---|
| 1 car | £4.99 | £19.99 | £15.00 |
| 2 cars | £9.48 | £39.98 | £30.50 |
| 3 cars | £13.48 | £59.97 | £46.49 |
| 5 cars | £21.48 | £99.95 | £78.47 |
The most expensive "discount" mistake is the opposite of a saving: HPI auto-enrols buyers into a £39/year HPI Watch subscription after the £19.99 check unless you opt out at checkout. Read the small print on any provider before paying, and prefer flat one-off pricing.

Stop hunting codes. The real 2026 price ladder for a full UK car check is £3.99 for bare-bones data, £4.99 for data plus analysis, and £4.00 per car when you check your whole shortlist together. Anything above that is brand premium, not better data.
Rarely. HPI occasionally runs multi-check bundle offers on its own site, but public discount codes for the £19.99 single check are almost always expired or fake copies posted on voucher sites to farm clicks. The reliable way to pay less for the same underlying Experian data is to use a cheaper provider: the identical stolen, finance and write-off databases are available from £4.99.
No code is needed. CarCostCheck's premium check is £4.99 flat, which is already 75% below HPI's £19.99 for the same Experian-sourced data. The built-in discount is for checking multiple cars: the 2nd car is 50p off and the 3rd to 5th cars are 99p off each, applied automatically at checkout with no code.
Voucher sites earn affiliate commission when you click through, whether or not the code works. Car history checks are low-priced products, so providers rarely fund genuine codes; the voucher pages exist to capture the search and redirect you. If a code is not published on the provider's own site, assume it does not work.
Total Car Check's Silver check at £3.99 is the cheapest bare-bones provenance check (stolen, finance, write-off only). CarCostCheck at £4.99 includes those same Experian checks plus MOT analysis, mileage verification, reliability scoring and running costs, which is the most data for around £5. Checking several cars brings CarCostCheck's per-car price down to £4.00.
Both occasionally discount within their member ecosystems, but their standard checks are £9.99 each and public codes are uncommon. Both use the same Experian data feed as the £4.99 and £3.99 providers, so even a generous AA or RAC code usually still leaves you paying more for identical provenance data.
