Legal & 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.

Legal claims and credit hire disputes come with their own vocabulary. Whether you are drafting a witness statement, responding to an insurer argument, or preparing documents for court, the terminology can feel impenetrable. This glossary defines the key terms, legal principles, and case law references you are most likely to encounter.

ABCDEFGHIJLMNOPRSTVWZ

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.
Awaab's Law
A statutory regime requiring landlords to investigate and fix prescribed hazards (notably damp and mould) within strict timescales. In force for social housing from 27 October 2025, with extension to the private rented sector to follow under the Renters’ Rights Act 2025. Strong evidence of what counts as a reasonable repair window in any HDR claim.

B

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.
Bolam v Friern Hospital Management Committee [1957] 1 WLR 582
The foundational test for clinical breach of duty: a clinician is not negligent if they acted in accordance with a practice accepted as proper by a responsible body of medical opinion skilled in that field. Applies to diagnosis and treatment but, since Montgomery, does not apply to risk disclosure and consent.
Bolitho v City and Hackney HA [1998] AC 232
A House of Lords gloss on Bolam: the responsible body of medical opinion relied on must itself be reasonable and logical and must withstand logical analysis. The court can reject an opinion that does not stand up to scrutiny.
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

Compliance Check
An automated or manual review of a legal document against applicable rules (such as CPR Part 32) to verify it meets required standards before submission.
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.
CPR Part 32
The Civil Procedure Rule governing witness evidence in England and Wales. Sets out the requirements for witness statements including format, content, and the statement of truth.
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 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.
Causation (clinical negligence)
The link between breach of duty and injury. The default test is "but for" on the balance of probabilities. Where multiple causes operate, material contribution may apply (Bailey v MoD [2008] EWCA Civ 883; Holmes v Poeton [2023] EWCA Civ 1377). Loss of chance below 50% is generally not recoverable (Gregg v Scott [2005] UKHL 2). In Montgomery cases, ask what this patient would have done if properly warned.

D

Defective Premises Act 1972, s.4
Where a landlord has a repairing obligation or right to enter and repair, the landlord owes a duty to take reasonable care that persons (including visitors) are reasonably safe from injury or damage from a relevant defect. Pleaded alongside the tenancy claim where disrepair has caused personal injury.
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].

Disrepair
Damage to, or deterioration of, the structure, exterior or listed installations of a dwelling that brings it below the standard required to maintain its character or function. Disrepair is the trigger for s.11 LTA 1985 liability and is distinguished from pure design defects (Quick v Taff-Ely BC [1986] QB 809).

E

Edwards v Kumarasamy [2016] UKSC 40
A Supreme Court decision on the scope of the s.11 LTA 1985 repairing covenant in respect of common parts. Confirms the limits of a landlord's implied obligation where the defect lies outside the demised premises and the landlord does not have an estate or interest in the relevant area.
Export Format
The file type a document is generated in for court use, typically Word (.docx) or PDF.

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.
Fitness for Human Habitation (Homes Act 2018)
The Homes (Fitness for Human Habitation) Act 2018 inserted ss.9A–9C into the Landlord and Tenant Act 1985. It implies a term that the dwelling is fit for human habitation at the start of and throughout the tenancy. Wider than s.11 because it does not require physical disrepair — a Category 1 HHSRS hazard can render a property unfit.

G

GTA (General Terms of Agreement)
The industry agreement between the ABI (Association of British Insurers) and the CHO (Credit Hire Organisation) 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, and dispute resolution. The most recent version was updated in 2024.

H

HHSRS (Housing Health and Safety Rating System)
The statutory hazard rating system used by local authorities to assess risks to health and safety in dwellings. A Category 1 hazard is the highest band and is strong evidence of unfitness for human habitation under s.9A LTA 1985.

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.

J

Judicial College Guidelines (JCG)
The standard reference work used in England & Wales for valuing general damages for pain, suffering and loss of amenity in personal injury and clinical negligence claims. Used alongside comparable reported awards.

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.
Landlord and Tenant Act 1985, s.11
The statute implying a repairing covenant into most tenancies under 7 years. The landlord must keep in repair the structure and exterior of the dwelling and the installations for water, gas, electricity, sanitation, space heating and water heating. For defects inside the demise, the landlord is liable from the point of notice and after a reasonable time to repair.
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.
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.

Limitation (clinical negligence)
3 years from the negligent act or omission or the claimant's date of knowledge under s.14 Limitation Act 1980, with s.33 discretion to disapply. Time runs from age 18 for children. Time may not run at all for protected parties who lack capacity.
Limitation (housing disrepair)
6 years from breach for the contractual disrepair claim; 3 years for any personal injury element from injury or knowledge. Issue within 6 years to recover damages for the whole disrepair period.

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.
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.
Material Contribution
A causation rule applied where injury has more than one operative cause and "but for" cannot be cleanly satisfied. See Bailey v Ministry of Defence [2008] EWCA Civ 883 and Holmes v Poeton Holdings Ltd [2023] EWCA Civ 1377 (confirming the rule applies to indivisible as well as divisible injuries).
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.
Montgomery v Lanarkshire Health Board [2015] UKSC 11
The Supreme Court decision on consent in clinical practice. A doctor must take reasonable care to ensure the patient is aware of material risks and reasonable alternatives. Materiality is judged from the perspective of the particular patient, not a responsible body of doctors. Bolam does not apply to risk disclosure.

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.

Notice (HDR)
In housing disrepair, the trigger for liability for defects inside the demise. The landlord must have actual or constructive notice of the defect and then a reasonable time to carry out works. Dating and proving notice is central to almost every HDR witness statement.

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.
Ogden Tables
The actuarial tables used to calculate future loss multipliers in personal injury and clinical negligence quantum. Applied via multiplier × multiplicand. The Personal Injury Discount Rate for England & Wales has been +0.5% from 11 January 2025, replacing −0.25%.

P

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 court looks at what a reasonable person in the claimant's position would have done, taking into account their specific circumstances.
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.
Periodical Payment Order (PPO)
A court order providing for future loss in serious personal injury or clinical negligence claims to be paid as periodic payments rather than a lump sum. Useful where investment risk and longevity risk on a lump sum would be unacceptable.
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.
PII Redaction
The process of removing or masking personally identifiable information from legal documents before processing or sharing.
Pirelli v Oscar Faber [1983] 2 AC 1
The leading authority on accrual of the cause of action in latent damage / disrepair claims at common law. Often cited on limitation in HDR claims to fix the date from which time begins to run.
Practice Direction 32
The supplementary guidance to CPR Part 32, setting out detailed requirements for how witness statements should be formatted, structured, and presented.
Pre-Action Protocol for the Resolution of Clinical Disputes
The CPR protocol governing pre-action conduct in clinical negligence. Records request → (optional) Letter of Notification → Letter of Claim → Letter of Response within four months. Independent experts on breach, causation and condition/prognosis are usually required; ADR encouraged.
Pre-Action Protocol for Housing Conditions Claims (England)
The CPR protocol governing pre-action conduct in housing disrepair claims in England. Early Notification Letter (optional) → Letter of Claim → disclosure of repair records → single joint expert inspection (normally within ~20 working days) → ADR.

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.
Renters' Rights Act 2025
Received Royal Assent on 27 October 2025 with staged commencement. Extends the Decent Homes Standard and Awaab’s Law to the private rented sector by regulation and abolished section 21 evictions from 1 May 2026. Materially shifts the standard owed by private landlords in HDR claims.
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.
Statement of Case
The formal documents that set out each party's case, including particulars of claim, defence, and any counterclaim.
Statement of Truth
A declaration required under CPR that the maker of a witness statement believes the facts stated are true. Must appear at the end of the statement and be signed.
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

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

Witness Statement
A written account of the facts of a case, given by a witness and used as evidence. In credit hire claims, typically covers the accident circumstances, need for a replacement vehicle, and the hire period.

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.
