84% of used EV buyers now actively ask: "what's the battery like?" Dealers with a documented answer sell faster, at higher margins, and have the documented FOS defence the Ombudsman looks for if a complaint ever lands. At RAA-exclusive pricing, sourced through the alliance's purchasing power.
"What's the battery like?", the single most-asked question on every used EV forecourt visit. An AVILOO certificate answers it definitively, and the commercial impact follows.
Certified EVs sell in 29 days on average, down from 45. Less floorplan cost, more stock turn, fewer hesitant buyers walking off the forecourt.
Independent battery evidence removes the single biggest price-objection on a used EV. Compete with the franchise networks on evidence, not on margin sacrifice.
84.4% of used EV buyers actively ask for battery health information. The dealers who can hand them a certificate close, the ones who can't, lose them to the dealer who can.
The upside is one side of the ledger. Here's the other, the cost of selling an EV without documented battery condition, taken from the largest analysis of FOS decisions ever conducted in the UK.
MotorCheck analysed every decision ever published by the Financial Ombudsman Service, 375,328 in total, and identified 271 verified EV battery complaints. In 49 of those cases, the Ombudsman explicitly weighed battery evidence as part of their reasoning. Collectively, more than £1 million in consumer claims was adjudicated. The outcome was binary.
A documented battery health check at the point of sale was enough. In every one of 29 cases where the dealer could produce independent evidence of battery condition, the complaint was dismissed.
No documentation. No defence. The Ombudsman's reasoning is consistent: "in the absence of any further evidence…", "no evidence has been provided…", "the vehicle health check recorded no issues."

Today's Ombudsman decisions concern EVs sold three to four years ago, when the UK EV parc was a fraction of its current size. Between 2026 and 2030, more than half a million EVs exit manufacturer warranty. The complaint volume we're seeing today is the leading edge, not the limit.
From 1 case in 2013 to 96 in 2025. The last two years have seen 71% and 93% year-on-year growth.
Today's FOS complaints stem from just 80,000 EVs exiting warranty. By 2030, that figure exceeds half a million.
Projected annual industry exposure by 2029. At current growth rates, with over half a million EVs exiting manufacturer warranty between 2026 and 2030, industry-wide EV complaint exposure could exceed £10 million annually, roughly six times the 2025 level. The mass-market wave has not yet reached the FOS.
The regulatory environment is moving unambiguously towards mandatory, independent, documented battery condition at point of sale. Selling, or financing, a used EV without knowing the state of its battery is increasingly difficult to reconcile with FCA Consumer Duty obligations to identify and mitigate foreseeable harms.
Firms must proactively identify and mitigate foreseeable harms. An undocumented used EV battery is, on the FOS evidence, a foreseeable harm. Recent Ombudsman decisions increasingly cite Consumer Duty directly.
Goods supplied under finance must be of satisfactory quality at point of supply. Within the first six months, faults are presumed to have been present, and the burden shifts to the dealer to prove otherwise.
Mandatory documentation of state of health, charge cycles, capacity, and maintenance history for every EV battery above 2kWh. UK consultation on mirrored requirements is already under way.
Mr R complained about a 20% range reduction in winter on his used Mercedes EV. He'd signed a £54,956 finance agreement and wanted the full sum refunded. The dealer won because, and only because, they had a documented EV battery health check on file from the day of sale.
A single rejected EV costs around £29,000. At your RAA-negotiated price, a single AVILOO check costs £33 + VAT. Stop one claim and you've paid for nearly 900 checks across the rest of your group's stock, every one of them adding a documented FOS defence to the deal.

AVILOO is the Austrian-engineered battery diagnostic platform distributed in the UK by MotorCheck. A plug-in OBD device captures cell-level data directly from the vehicle and AVILOO's cloud issues a VIN-tied, third-party certificate, the kind of independent, methodology-backed evidence the Ombudsman looks for.
OBD-connected unit plugs into the vehicle. No workshop, no ramp, no technician training required.
Three minutes to capture cell-level data directly from the battery, far beyond what the car's own BMS reports.
AVILOO's cloud issues a third-party, VIN-tied certificate with independently-verified state of health.
Retain the certificate alongside the finance agreement. If a complaint lands months later, the evidence is already on file.
Watch how a dealer or technician runs the full battery test on any EV, from plugging in the OBD device to issuing the independent certificate.
The AVILOO certificate documents the battery's exact state of health on the date the test was run, the precise evidence the Ombudsman looks for when asking whether a fault was "present or emerging at the point of supply". A clean certificate at sale = a documented "no" to that question, retained for the life of the agreement.
AVILOO is procured through the RAA framework like any other strategic supplier, one negotiated commercial position, deployed across your group's franchises with central billing and consolidated reporting. The unit lives on the workshop floor, runs in three minutes per car, and produces a VIN-tied independent certificate that lives alongside the deal pack, the precise evidence the Ombudsman looks for when a complaint lands months or years later.
£33 + VAT per test, and zero unit rental fee for the first year with no minimum monthly volume, the most aggressive AVILOO pricing available anywhere in the UK, negotiated by the RAA on behalf of its 33 shareholders.
Pull any vehicle's battery certificate by VIN, registration, or stock number. When a customer or finance house asks "where's the evidence?", you open the file and it's there.
Certificates are preserved alongside the deal record for as long as the finance agreement runs. When a complaint lands two, three, four years after drawdown, the evidence is still there to defend it.
Run a single unit at one site or roll out across every franchise in your group, MotorCheck handles deployment, training, and central billing. One supplier, one invoice, one set of terms across your network.

"Of all the new commercial risks facing UK motor dealer groups today, undocumented EV battery condition at point of sale is among the fastest-growing, and the easiest to prevent. A documented, independent battery report is the most effective form of evidence we've seen emerge in this space, and exactly the kind of commercial position the RAA exists to negotiate on behalf of its members."
Every dot on the map is an active AVILOO unit in the UK today, already running tests, already issuing certificates, already protecting dealer finance books against the next FOS complaint. From the UK's largest automotive traders to independent dealerships, businesses are embedding independent battery evidence into their used EV process.
…and hundreds of UK car dealers building trust with every EV sale.
Reinsured by Swiss Re, one of the world's largest reinsurers.
Every eligible EV you certify with AVILOO will soon carry an independent warranty that travels with the vehicle. It's the first and only EV battery test in the market backed this way, with genuine financial substance behind it, not just a company's own promise. It gives your customers real reassurance, and you a stronger story at the point of sale, included at no extra cost.
It's a separate, financially-backed warranty issued alongside the independent AVILOO battery certificate and reinsured by Swiss Re. The certificate records the battery's health on the day of the test; the warranty adds protection if that battery degrades faster than forecast during the cover period.
No. They are two separate documents. The certificate is independent evidence of the battery's condition at the point of sale. The warranty is an added layer on top that travels with the vehicle, protecting against abnormally fast degradation.
Twelve months or 20,000 km from the date of the AVILOO test, whichever comes first. The period is fixed from the test date and printed on the warranty certificate.
Eligible battery-electric vehicles (BEVs) that pass AVILOO's automatic eligibility check at the time of the test. Plug-in hybrids still receive a full AVILOO certificate, but the warranty itself is for BEVs. The vehicle's model also needs to be on AVILOO's coverage list and pass the Flash Test cleanly, and batteries that are already heavily degraded may not qualify.
Nothing extra. It's included with every eligible AVILOO Flash Test at no additional cost, with no separate product to price up.
Yes. The warranty covers eligible vehicles whether the customer buys outright or on PCP or hire purchase, and it travels with the car if it's sold on during the cover period.
A fixed £2,700, paid to the owner if the battery falls below its certified threshold. It's a set cash sum, not a contribution towards a repair, and the validation test is refunded on a confirmed claim.
Within the cover period the owner has a second AVILOO Flash Test and submits the claim directly to AVILOO. If it confirms the battery has dropped below its threshold, AVILOO pays the £2,700 and refunds that test. The claim is handled by AVILOO, not the dealer.
It's issued digitally through AVILOO Connect alongside the test result, not posted or emailed as a separate PDF.
