Why Battery Health Checks Matter
The Market Is Moving. Are You Ready?
The Compliance Gap
29% of UK dealers currently do zero battery health checks on used EVs before selling them. That's nearly a third of the market operating without evidence, without compliance, and without defence when a claim arrives.
Consumer Rights Act 2015
Every used car sold by a dealer must be:
- Satisfactory quality — including durability
- Fit for purpose — especially if the buyer stated a specific need
- As described — all claims must be accurate
The critical rule: Within the first 6 months, any defect is presumed to have been present at delivery unless the dealer can prove otherwise. We cover the full Consumer Rights Act implications for EV dealers in detail.
"Sold as seen" clauses are void under consumer law. Dealers cannot opt out of these obligations.
What the Test Does — and Doesn't Do
An AVILOO battery health test reports the current condition of the traction battery at the time of testing. That is exactly what matters for Consumer Rights Act compliance: documented, independent evidence of the battery's state at the point of sale.
The test does not forecast future battery health, nor does it cover mechanical or electrical safety inspections. It is a snapshot — a TÜV-certified, cell-level analysis of where the battery stands right now.
For dealers, that snapshot is the critical piece. It proves you knew the condition of the battery when you sold the vehicle, and that the buyer was informed. That is your defence under the reversed burden of proof.
Disputes Are Surging
| Year | Motor Ombudsman EV Disputes | Growth |
|---|---|---|
| 2023 | 1,222 | — |
| 2024 | 1,951 | +60% |
| 2025 | 2,805 | +44% |
- Average dispute claim: £6,193
- 29% of claimants seek full vehicle rejection
- Battery replacement cost: £12,000–£25,000+
Without a documented battery health check at the point of sale, dealers have no evidence to counter claims that a fault was present at delivery. A single certificate changes that.
Regulation Is Coming
The EU Battery Regulation (2023/1542) introduces mandatory Battery Passports from February 2027. While the UK isn't directly bound, the government has signalled alignment with equivalent standards.
Labour committed to standardised battery health certificates in their 2024 manifesto. Dealers who adopt now future-proof themselves. Read our EU Battery Passport 2027 preparation guide for the full timeline.
The Business Case
A £35 test that delivers:
- £450–£900 price uplift per vehicle
- 57% more buyers enter the market with certificates available
- One prevented return pays for thousands of tests
- Faster sales, higher margins, fewer disputes
