UK Credit Hire Glossary

Key terms, legal principles, and case law explained in plain language.

Disclaimer: This glossary is general guidance, not legal advice. Terms are simplified for accessibility. Always refer to the original authorities for full legal context.

Credit hire has its own language. If you work in the industry, you use these terms every day. If you are new to it, or dealing with a credit hire claim for the first time, the terminology can feel impenetrable. This glossary defines the key terms, legal principles, and case law references you are most likely to encounter.

A B C D E F G H I L M N O P R S T V W Z

A

ACRISS Code (also SIPP Code): A standardised four-character code used internationally to classify rental vehicle types. Each character represents a category (size, doors/type, transmission, fuel/air conditioning). ACRISS codes are important in credit hire disputes because they provide an objective way to compare vehicles when assessing whether a hire vehicle was of an equivalent class to the damaged vehicle.
Accident Management Company: A company that coordinates the post-accident process for a claimant, typically arranging credit hire, vehicle recovery, repair, storage, and personal injury referrals. Accident management companies act on behalf of the claimant and usually recover their costs from the at-fault insurer.
Assignment: The transfer of a legal right from one party to another. In credit hire, the claimant typically assigns the right to recover hire charges to the credit hire organisation, allowing the CHO to pursue recovery in its own name. The operation of assignments was confirmed in Clark v Ardington Electrical Services [2002] EWCA Civ 510.

B

Bailee: A person in lawful possession of goods belonging to another. In credit hire, a bailee (for example a leasing company that owns the damaged vehicle while the claimant uses it under contract) may have possessory title sufficient to bring a claim for hire and damage charges in its own right.
Basic Hire Rate (BHR): The rate a court uses to assess the reasonable cost of hiring a replacement vehicle. It represents what a reasonable person could have paid a mainstream rental supplier for a comparable vehicle, in the same locality, on similar terms. Where a claimant is not impecunious, recovery is typically limited to the BHR rather than the higher credit hire rate.
Key case law: Stevens v Equity Syndicate Management Ltd [2015] EWCA Civ 93; Bunting v Zurich Insurance Plc [2020] EWHC 1807 (QB).
BHR Evidence: The evidence submitted to court to establish the Basic Hire Rate. This typically includes quotes or screenshots from mainstream suppliers showing rates available for a comparable vehicle in the claimant's locality at the time hire was needed. BHR evidence should capture vehicle class (ACRISS/SIPP code), branch location, lead time, payment method, excess levels, deposit requirements, mileage caps, and any relevant terms and conditions.
Bunting v Zurich Insurance Plc [2020] EWHC 1807 (QB): A High Court decision in which Pepperall J dismissed an appeal against a trial judge's BHR assessment, describing the grounds as a "nit-picking challenge to the judge's findings of fact." The case confirms that BHR assessment is a fact-sensitive exercise for the trial judge and that appellate courts will not interfere absent legal error or perversity. It does not prevent rigorous factual challenges at first instance.

C

Consumer Credit Act 1974: Legislation that regulates consumer credit agreements in the UK. Credit hire agreements may be classified as regulated agreements under this Act. The leading authority on this point is Dimond v Lovell [2002] 1 AC 384, which held that an improperly regulated credit hire agreement cannot be enforced.
Copley v Lawn [2009] EWCA Civ 580: The Court of Appeal decision setting out when a claimant can reasonably refuse an intervention offer from the at-fault insurer. The court held that refusal is not automatically unreasonable and that the burden lies on the insurer to show the offer was genuinely capable of acceptance and that refusal failed the mitigation test.
Credit Hire: The provision of a replacement vehicle to an innocent party following a road traffic accident, where the cost of the hire is paid on credit terms. The claimant does not pay upfront. Instead, the credit hire company provides the vehicle and recovers the cost from the at-fault driver's insurer. Credit hire rates are typically higher than mainstream rental rates because they include additional services and the credit element.
Credit Hire Agreement: The contract between the claimant and the credit hire company. It sets out the terms of the hire, the vehicle provided, the daily rate, and the basis on which the cost will be recovered from the at-fault insurer. The agreement must comply with relevant consumer credit legislation to be enforceable.
Credit Hire Organisation (CHO): A company that provides replacement vehicles to non-fault drivers on credit terms following a road traffic accident, then pursues the at-fault insurer for the hire charges. CHOs may be GTA-subscribing or non-GTA. Their commercial model relies on the legal principle of restitutio in integrum.
Credit Hire Rate: The daily rate charged by a credit hire company for the provision of a replacement vehicle. This rate is typically higher than the BHR because it includes credit terms, accident management services, delivery and collection, and other elements not included in a standard mainstream rental. Where a claimant is impecunious, the credit hire rate may be recoverable. Where they are not, recovery is usually limited to the BHR.

D

Dimond v Lovell [2002] 1 AC 384: A House of Lords decision that established two key principles. First, that a credit hire agreement is a regulated agreement under the Consumer Credit Act 1974, and if improperly regulated, it cannot be enforced. Second, that where a claimant has available funds to hire on the open market, recovery is limited to the reasonable market rate (BHR), not the higher credit hire rate including credit-service elements.
Diminution (Loss of Value): The reduction in a vehicle's market value following an accident, even after professional repair. A vehicle with an accident history recorded on HPI/Experian will always sell for less than an identical vehicle with a clean history. Diminution is a recoverable head of damage, separate from the cost of repair.
Key case law: Payton v Brooks [1974]; Earle v Charalambous [2006]; Jackson v Marley [2004].
Direct Hire: A replacement vehicle supplied directly by the at-fault insurer (or its nominated supplier) under an intervention offer, rather than by a credit hire organisation. Direct hire is typically priced at mainstream rates because the insurer pays for it directly.

E

Enforceability: Whether a credit hire agreement can be sued upon. Following Dimond v Lovell, a regulated credit hire agreement that fails to comply with the Consumer Credit Act 1974 is unenforceable. Modern agreements are typically drafted to fall within the FSMA Regulated Activities Order Article 60F exemptions to avoid this outcome.
Excess: The amount a hirer must pay towards any damage to the hire vehicle. Mainstream suppliers typically include an excess of £500 to £1,500, while credit hire agreements usually offer nil excess as standard. The cost of achieving nil excess at a mainstream supplier is treated as a separate uplift when calculating BHR.
Key case law: McBride v UK Insurance Ltd; Clayton v EUI Ltd [2017] EWCA Civ 144.

F

Fixed Recoverable Costs (FRC): A regime that caps the legal costs recoverable in certain civil claims. Since October 2023, fixed costs have been extended to fast track claims and monetary claims up to £100,000, capturing the majority of credit hire disputes. This changes the economics of litigation for both claimants and defendants.
FSMA RAO Article 60F: Article 60F of the Financial Services and Markets Act 2000 (Regulated Activities) Order 2001. The article exempts certain credit arrangements from regulation. Two limbs matter in credit hire: 60F(2) (credit for business purposes) and 60F(3) (free-of-interest credit under £25,000 repayable in 12 months or fewer in not more than four instalments). Modern credit hire agreements are drafted to fall within one of these exemptions.

G

General Terms of Agreement (GTA): The industry agreement between the ABI (Association of British Insurers) and subscribing credit hire organisations that sets out a framework for the handling and settlement of credit hire claims. The GTA includes protocols for the provision of replacement vehicles, rate structures, intervention timescales, late-payment penalties and dispute resolution. The version in force at the date of hire governs the rate.
Giles v Thompson [1994] 1 AC 142: A House of Lords decision confirming the lawfulness of credit hire arrangements and the recoverability of hire charges from the at-fault insurer. The case is a foundational authority for the credit hire industry.

H

Highway Code: The official guide to road use in Great Britain. Highway Code rules are not direct sources of liability but courts treat compliance as evidence of reasonable conduct and breach as evidence of negligence. Rules are routinely cited in liability arguments at first instance.
Hussain v EUI Ltd [2019] EWHC 2647 (QB): A High Court decision sharpening the evidential burden for impecuniosity. The court held that impecuniosity must be properly pleaded and properly evidenced, with at least three months of bank statements, credit card statements, payslips and evidence of available credit. A bare assertion will not succeed.

I

Impecuniosity: The financial inability of a claimant to pay for a hire vehicle on the open market. Where impecuniosity is established, the claimant may recover the full credit hire rate rather than being limited to the BHR. The test, established in Lagden v O'Connor [2003] UKHL 64, asks whether the claimant could have paid hire charges "without making sacrifices the plaintiff could not reasonably be expected to make." The burden of proof is on the claimant, as confirmed in Zurich Insurance Plc v Umerji [2023] EWCA Civ 357.
Intervention: The process by which an at-fault insurer contacts the claimant directly to offer a replacement vehicle, typically from a mainstream supplier at BHR, as an alternative to credit hire. Successful intervention reduces the insurer's outlay but must comply with regulatory standards and the claimant's right to choose their own provider.

L

Lagden v O'Connor [2003] UKHL 64: The House of Lords decision that established the impecuniosity test in credit hire claims. Lord Nicholls held that an impecunious claimant is entitled to recover the reasonable costs of credit hire, even where those exceed the basic hire rate, provided they could not have paid for a mainstream hire without making unreasonable sacrifices.
Liability: The legal responsibility for causing the accident. In credit hire claims, liability determines which party's insurer is responsible for the hire costs. Liability can be full (100% one party's fault), split (shared fault, e.g. 50/50 or 75/25), or disputed. The allocation of liability directly affects the recoverable amount.
Like-for-Like: The rule that a replacement vehicle should be reasonably equivalent to the claimant's own vehicle in terms of size, type and specification. Identity of make and model is not required, but a claimant who drove an executive saloon is entitled to an executive saloon, not a supermini.
Locality: The geographic area relevant to assessing the BHR. Courts assess what mainstream rates were available in the claimant's locality, not nationally. This means the nearest mainstream supplier branches to the claimant's home or workplace.
Key case law: Stevens v Equity Syndicate Management Ltd [2015] EWCA Civ 93.

M

Mainstream Supplier: A conventional car rental company that offers vehicles on standard commercial terms (pay on collection or prepay). Examples include Enterprise, Hertz, Europcar, and Sixt. The BHR is assessed by reference to what a reasonable person could have paid at a mainstream supplier.
Mattocks v Mann [1973] RTR 13: A starting-point authority on the recoverable period of hire. The case confirms the recoverable period tracks the reasonable repair window or, in total loss cases, until pre-accident value is paid plus a reasonable replacement period. Subsequent authority has refined the analysis.
McBride v UK Insurance Ltd; Clayton v EUI Ltd [2017] EWCA Civ 144: A Court of Appeal decision that confirmed nil-excess should be treated as a separate question when assessing BHR. Where mainstream comparators include an excess, the cost of achieving nil excess can be added as a reasonable uplift to the BHR.
Mitigation of Loss: The legal duty on a claimant to take reasonable steps to minimise their loss. In credit hire, this means the claimant should not hire for longer than reasonably necessary, should consider whether a hire vehicle is genuinely needed, and should take reasonable steps to resolve the claim promptly. The standard is reasonableness, not perfection.

N

Need (for a Hire Vehicle): The requirement for a replacement vehicle during the period the claimant's own vehicle is unavailable. Courts assess need based on the claimant's actual circumstances: whether they used their vehicle daily, whether alternative transport was available, and whether the hire was genuinely required rather than merely convenient.
Nil Excess: A hire agreement with no excess (the amount the hirer must pay towards any damage to the hire vehicle). Mainstream rental suppliers typically include an excess of £500 to £1,500. Credit hire agreements usually offer nil excess as standard. When assessing BHR, the cost of achieving nil excess at a mainstream supplier is treated separately and can be added as an uplift.
Key case law: McBride v UK Insurance Ltd; Clayton v EUI Ltd [2017] EWCA Civ 144.

O

Official Injury Claim (OIC) Portal: The online portal launched in May 2021 for processing road traffic accident personal injury claims valued under £5,000. The OIC was introduced as part of the whiplash reform programme under the Civil Liability Act 2018. Credit hire claims are not processed through the OIC, but the reforms have indirect effects on credit hire through changes to claim volumes, fraud patterns, and the economics of litigation.

P

Part 36 Offer: A formal settlement offer made under Part 36 of the Civil Procedure Rules. Part 36 offers carry costs consequences if the recipient fails to beat the offer at trial, an important tactical tool in credit hire litigation for both claimants and defendants.
Pattni v First Leicester Buses Ltd; Bent v Highways and Utilities Construction [2011] EWCA Civ 1384: A Court of Appeal decision that established the objective "person such as the claimant" test for assessing the reasonable cost of hire. The case also sets out the eight-principle framework for assessing impecuniosity, looking at income, outgoings, savings, available credit, dependants and whether using available funds would have required unreasonable sacrifices.
Period of Hire: The duration for which a replacement vehicle is provided. The recoverable period is the time the claimant reasonably needed a hire vehicle, which may differ from the actual hire duration. Courts assess reasonableness based on the time needed for repair or replacement, the claimant's actions in progressing the claim, and any delays attributable to either party.
PII (Personally Identifiable Information): Data that can identify a specific individual, such as names, addresses, dates of birth, and vehicle registration numbers. PII masking or redaction is important in credit hire operations to comply with GDPR and data protection requirements, particularly when using AI tools that process claim correspondence.
Pre-Action Protocol: A set of procedural rules under the Civil Procedure Rules governing what the parties must do before issuing court proceedings. The Pre-Action Protocol for Road Traffic Accidents and the Pre-Action Protocol for the Resolution of Personal Injury Claims both interact with credit hire claims and set timescales for disclosure, response and settlement attempts.

R

Rate Evidence: The evidence used to establish what rates were available in the market at the relevant time. Rate evidence typically includes screenshots of mainstream supplier websites showing rates for a comparable vehicle in the claimant's locality, captured at or near the date hire was needed.
Restitutio in Integrum: The foundational legal principle that the innocent party should, as far as money can do it, be placed in the same position they were in before the tort was committed. This principle underpins all tortious compensation claims, including credit hire and diminution.

S

Small Claims Track: The court track for civil claims of lower value. For RTA-related personal injury, the small claims limit was raised to £5,000 in May 2021 as part of the whiplash reforms. Costs recovery is limited on the small claims track, which affects the commercial viability of pursuing credit hire losses alongside injury claims in this track.
Stevens v Equity Syndicate Management Ltd [2015] EWCA Civ 93: A Court of Appeal decision that established the key principles for assessing BHR. The court held that BHR should be based on the lowest reasonable rate from a mainstream supplier, in the claimant's locality, for a comparable vehicle. This case is the primary authority on the objective BHR test.
Storage Charges: Charges for storing a damaged vehicle after an accident, typically at a recovery yard or repair facility. Storage charges can accumulate quickly and are a common area of dispute between credit hire companies and insurers.
Subrogation: The process by which an insurer, having paid a claim, takes over the claimant's right to recover the loss from the at-fault party. In credit hire, the credit hire company may have subrogated rights to pursue recovery of the hire charges from the at-fault insurer.

T

Total Loss: A vehicle declared uneconomic to repair, where the cost of repair exceeds the pre-accident value. In credit hire, total loss claims engage a separate recoverable period running from the date hire commenced until the date the claimant receives pre-accident value plus a reasonable period to source a replacement vehicle.
TPI (Third-Party Insurer): The insurer of the at-fault driver. In credit hire claims, the TPI is the party from whom the hire costs are recovered. TPI correspondence refers to the letters and communications from the at-fault insurer challenging or disputing the credit hire claim.
TPI Correspondence: Letters from the third-party insurer challenging aspects of a credit hire claim. Common challenges include rate (arguing the BHR should be lower), period (arguing the hire was longer than necessary), need (arguing the claimant did not require a hire vehicle), impecuniosity (arguing the claimant could have afforded to hire on the open market), and mitigation (arguing the claimant failed to take reasonable steps to minimise loss).
Tariff Damages: Fixed compensation amounts for whiplash injuries introduced by the Civil Liability Act 2018. The tariff sets prescribed damages based on injury duration, replacing the previous common law assessment. A 15% uplift took effect from May 2025.

V

Vehicle Diminution: See: Diminution (Loss of Value).

W

Without Prejudice: A label applied to correspondence and offers exchanged for the purpose of settlement. Without prejudice material is generally inadmissible in evidence on the substantive issues, encouraging frank settlement discussion. "Without prejudice save as to costs" extends inadmissibility but allows the material to be referred to on the question of costs after judgment.

Z

Zurich Insurance Plc v Umerji [2023] EWCA Civ 357: A Court of Appeal decision that confirmed the burden of proof for impecuniosity lies with the claimant, who must "plead and prove" their case. The court also confirmed that impecuniosity is relevant to both the rate and the period of hire.
