Lithium battery fire risk and EV recovery handling

section

What thermal runaway actually is

Thermal runaway is a self-sustaining exothermic reaction inside a lithium-ion battery cell. It begins when a cell is damaged (physically or electrically), overheated, or undergoes internal short-circuit. The damaged cell heats neighbouring cells; they in turn heat further cells. The reaction produces heat, gas (including hydrogen fluoride), and eventually fire.

The characteristic of thermal runaway is that it cannot be stopped by removing the ignition source: the battery is both the fuel and the heat source. Water suppresses the temperature but does not stop the electrochemical reaction; the cell must be cooled below the runaway threshold continuously. Fire services use immersion tanks or continuous water application for hours.

In a collision-damaged EV, thermal runaway may begin immediately, or may be delayed by hours or days as electrolyte slowly contacts damaged cell chemistry. This is the reason collision-recovered EVs are held in isolation compounds, not in standard vehicle storage.

insight

How recovery operators handle thermal runaway risk

At the scene: the operator checks for visible damage to the battery pack (underside inspection), smoke, unusual odour, or electrolyte leakage. If any of these are present, the vehicle is treated as a thermal runaway risk and the operator maintains a safe distance. No wheel-lift under a damaged pack.

During transit: a thermally suspect EV travels on a flatbed with the operator monitoring for smoke. The cab of the recovery vehicle has a fire extinguisher rated for lithium fires (Class D or a specialist EV suppression agent). The operator's route avoids tunnels where possible.

At the compound: the vehicle is parked in an isolation bay, a reinforced bay, outdoors or in a well-ventilated area, away from other vehicles and structures. The compound operator monitors the vehicle for 24 to 72 hours before transferring to the insurer's salvage agent.

Where the vehicle goes after a thermal runaway recovery

A collision-damaged EV is a write-off in the vast majority of cases, not because the vehicle is necessarily beyond structural repair, but because the cost of inspecting, certifying and replacing the traction battery exceeds the vehicle's market value. The insurer's salvage agent takes the vehicle to an EV salvage facility with the equipment to safely drain, discharge and depollute the pack.

Authorised Treatment Facilities (ATFs) licensed for EV handling are listed in the Environment Agency directory. Not all ATFs have EV capability; the facility must have specialist training, containment equipment and a fire-suppression water supply before the EA grants EV endorsement.

The Certificate of Destruction issued by the ATF is the document that closes the vehicle's DVLA record. The keeper retains a copy; the DVLA removes the vehicle from the taxed and MOT-required register.

Why this question keeps coming up

Drivers ask about Lithium battery fire risk and EV recovery handling because the recovery industry rarely answers the question on its own pages. Headlines start at "from £X" and grow without explanation. This guide gives you the published answer with primary-source citations so you can audit it.

The framework throughout is UK statute, the Highway Code, the National Highways framework, the BSI standard for recovery management, and the Health and Safety Executive guidance on lifting equipment. See the citations panel at the bottom.

in the press

The framework in plain English

UK vehicle recovery sits at the intersection of road law, work-equipment law and consumer-protection law. The starting point is the Road Traffic Act 1988 which covers driving offences and police-instructed removal under section 165A. The operational procedure is PAS 43 administered by the British Standards Institution.

Motorway and managed-trunk-road work runs on the National Highways recovery framework; the rate is statutory. Council-instructed work runs under the Refuse Disposal (Amenity) Act 1978. Private-land removal is the Protection of Freedoms Act 2012 Schedule 4 regime.

Consumer protection in any direct booking comes through the Consumer Rights Act 2015 and the Citizens Advice consumer guidance.

What the price actually depends on

Distance from operator base to scene affects attendance time but not the published band. Vehicle class affects the band: a car is not the same lift as a van, an EV, a classic car, a motorhome or an HGV. Service type sets the framework: roadside jump start, fuel delivery, flat-tyre swap, lockout assistance, local tow, regional tow, long-distance tow, motorway recovery, accident recovery, illegal parking removal, abandoned-vehicle removal, scrap pickup, EV recovery, motorbike recovery.

Variables NOT in the band: time of day, day of week, urban vs rural postcode at booking. Operators on the panel attend on the same rate regardless of region.

See the pricing page for the full table and the methodology.

What to do at the scene

Move the vehicle to the safest position you can reach. On a motorway exit on the passenger side, get behind the safety barrier, dial 999. Highway Code rules 274 to 287 cover the full procedure; see gov.uk.

On an A-road or in an urban area, switch on hazards, place a warning triangle behind the vehicle where it is safe to do so (not on a motorway), and stand clear of traffic. Call the booking line or open the contact form.

When the dispatcher answers: state your location (postcode is enough), your vehicle class and registration, the destination, and any access constraints. The indicative band is quoted before the operator is dispatched.

insight

Common pitfalls and how to avoid them

  • Misreported vehicle class. A flatbed for a Luton van is not the truck for a low-clearance sports car. Read the V5C class field before booking.
  • Wrong destination. A garage that turns out to be closed costs the operator a wait or a compound drop. Confirm opening hours.
  • Missing locking wheel-nut key. Most operators carry a master-key set but not for every car. Check the boot before the operator arrives.
  • EV on the road wheels. Always flatbed an EV. Regen and the permanent-magnet motor damage the inverter even on a short distance.
  • Decanting fuel at the wrong vehicle. Five litres of petrol in a diesel will air-lock the common rail and may damage injectors. Confirm fuel type before the decant.

Why the published rate matters

Bait pricing has been the recovery industry default for as long as the industry has existed. Headlines start low, the bill ends high, and the customer has no leverage at the scene because the truck is already loaded. The published-rate model is the answer to that.

Every figure on cheap car tow comes from a single source-of-truth table. The dispatcher reads the same band the customer reads on the page. The operator agrees to attend on the band. There is no surprise at the scene.

This is one of those rules that is easy to write down and hard to keep. It requires an operator panel that has accepted the framework, a dispatcher process that does not allow per-booking margin tweaks, and continuous transparency policing. We do all three.

Insurance and reimbursement

Most comprehensive motor policies include a recovery clause. Where the insurer instructs us directly we invoice them and the driver pays nothing at the scene. Where the driver pays at the scene the VAT invoice is the document submitted to the insurer for reimbursement.

For a non-fault accident the third-party insurer is liable for the recovery cost; the driver's own insurer routes the recovery instruction. Credit hire (a courtesy vehicle while the recovered car is off the road) is a separate service from recovery. See Association of British Insurers for the wider insurance framework.

Subrogation is the insurer's right to recover paid claim costs from a liable third party. For recovery costs the subrogation route is the standard claims procedure.

When to call a recovery vs sort it yourself

A flat 12V battery in a car park with a willing neighbour and a jump pack is a self-sort. A flat 12V on the hard shoulder of a motorway is a recovery, every time, because PAS 43 working procedure cannot be reproduced by a driver standing in lane one.

A simple tyre swap with a full-size spare on a verge with daylight is a self-sort if the locking nut key is present and the surface is level. A tyre swap on a steep camber with the spare hidden behind a boot full of luggage is a roadside-assistance call.

Out of fuel on a forecourt's doorstep is a five-minute walk with a jerry can. Out of fuel on a quiet B-road at midnight is a fuel-delivery booking.

Where the vehicle ends up

Default destination is the address you nominate at booking. Where no destination is named, the operator delivers to their secure compound and the keeper collects within the published storage window.

For end-of-life pickups the vehicle goes to an Authorised Treatment Facility from the Environment Agency directory. The ATF depollutes and destroys the vehicle under the End-of-Life Vehicles Regulations 2003 and issues a Certificate of Destruction.

For council-instructed recoveries the vehicle goes to the council's contracted compound; the release procedure is set by the council and is not subject to change by us.

Comparison points across the UK

Recovery practice is broadly uniform across the UK because the same operational standard (PAS 43), the same lifting-equipment regime (LOLER, PUWER) and the same Road Traffic Act apply UK-wide. The differences are in council enforcement procedures, Low Emission Zone schemes, and the police force structure.

In England and Wales the abandoned-vehicle framework is the Refuse Disposal (Amenity) Act 1978. In Scotland the equivalent is the Civic Government (Scotland) Act 1982 sections 99 to 103. In Northern Ireland the Pollution Control and Local Government (NI) Order 1978 covers the same ground. The procedure is similar in all three: notice to keeper, statutory holding period, then disposal.

Clean Air Zone, Low Emission Zone and Ultra Low Emission Zone schemes are run by individual councils or city regions. London ULEZ, Birmingham CAZ, Bath CAZ, Bristol CAZ, Newcastle Tyneside CAZ, Sheffield CAZ, Portsmouth CAZ, Bradford CAZ, Oxford ZEZ, York CAZ all charge non-compliant vehicles entering the zone. The Scottish LEZ scheme operates in Aberdeen, Dundee, Edinburgh and Glasgow.

How to verify the cost yourself

If you want to audit a recovery cost rather than take a published rate on trust, the steps are: ask the operator for the PAS 43 panel reference, ask for the LOLER thorough-examination date on the lift equipment used, ask for the photographic recovery sheet, and check the operator's company against Companies House.

For motorway recoveries the police-instructed dispatcher's reference is on the receipt left in the windscreen; the compound that holds the vehicle releases on payment of the published National Highways tariff. The tariff itself is available through the National Highways customer service line.

For council recoveries the council's contracted compound publishes the release procedure and the fee schedule on the council website. The fee is set by the council, not by us; we route the recovery but do not handle the release.

Common questions readers send us after this guide

Q: Will my insurer accept a recovery sheet from a non-AA operator? A: Yes; all comprehensive motor policies recognise PAS 43 compliant operators. The recovery sheet, the VAT invoice and the photographic record together form the claim evidence; the insurer's claims department processes them under the Insurance Conduct of Business Sourcebook (ICOBS).

Q: Can I refuse a recovery operator instructed by the police? A: Not on a live motorway; the carriageway has to be cleared for safety. Once the vehicle is at the holding compound the keeper can move it on at their own arrangement. The statutory cost of the initial recovery has to be paid before release.

Q: Does a recovery affect my no-claims bonus? A: A recovery by itself does not affect NCB. A claim made on the recovered vehicle (own damage, third-party damage) can affect NCB depending on whether it is at fault or non-fault. The insurer's claims handler decides; the recovery operator does not influence the NCB outcome.
