The GTA Explained

The GTA, or General Terms of Agreement, is a voluntary industry protocol between subscribing credit hire organisations and insurers that sets agreed daily hire rates, vehicle categories and payment timescales so that non-fault claims can settle without litigation. It decides whether a credit hire claim settles in weeks at protocol rates, or in months through litigation at BHR, so knowing which insurer subscribes, which version applies and which category the vehicle falls into is fundamental to running a file efficiently.

This guide explains the GTA in plain English: what it is, what it does, what its limits are, and how it interacts with the wider case law on rate, period and mitigation.

What the GTA is

The GTA is a voluntary, contractual protocol between credit hire organisations and subscribing motor insurers, administered under the auspices of the Association of British Insurers (ABI). It is not legislation, it is not court rules, and it does not bind any party that has not chosen to subscribe. What it does is set agreed rates, timescales and processes so the volume of credit hire claims can be settled without litigation.

Which version applies?

The version of the GTA in force at the date of hire governs the rate, not the version current at settlement or trial. Multiple versions have been issued (including significant revisions in recent years). A claim that hired in one rate period and settles in another is governed by the rate published in the version in force when the hire vehicle was supplied. Mixing versions is a common defence-side trap to spot.

Vehicle categories

The GTA classifies replacement vehicles into categories derived from the ACRISS (Association of Car Rental Industry Systems Standards) coding system. Categories cover engine size, body style, transmission and broad vehicle type. The category drives the rate. Disputes over vehicle category are common, the claimant\'s pre-accident vehicle\'s ACRISS code determines the like-for-like band, and the CHO\'s supplied vehicle must fall within it.

Daily rates and regional structure

GTA daily rates are published by category and region. The regional structure reflects the differing mainstream supplier pricing across the UK (London, Greater London, urban, rural). Within a region, the GTA rate is fixed for each category and is what a subscribing TPI is taken to have agreed to pay for a protocol claim.

Late payment penalties

One of the GTA\'s most commercially important provisions is the late payment regime. Where a subscribing TPI fails to settle a protocol-compliant invoice within the agreed timescales, the GTA imposes interest and administrative charges. These penalties are designed to make it cheaper for a TPI to pay than to delay, and they sit alongside any contractual or statutory interest the claimant could otherwise claim.

Intervention under the GTA

The GTA contains a specific intervention protocol. A subscribing TPI that wishes to intervene must do so within prescribed timescales, must offer a compliant vehicle, and must comply with the protocol\'s notice provisions. A TPI that fails to follow the protocol may lose the right to argue mitigation later. Conversely, a claimant who unreasonably refuses a compliant offer may face the Copley v Lawn [2009] EWCA Civ 580 mitigation analysis.

When the GTA does not apply

The GTA does not apply where:

• The CHO is not a GTA subscriber.
• The TPI is not a GTA subscriber.
• The vehicle category falls outside the categories the GTA covers (e.g. very prestige, specialist or modified vehicles).
• The protocol has been exited by either party in accordance with its own terms.

Where the GTA does not apply, the rate analysis falls back to first principles: actual rate charged, BHR comparators under Stevens v Equity Syndicate Management [2015] EWCA Civ 93, and impecuniosity analysis under Lagden v O\'Connor [2003] UKHL 64 and Pattni v First Leicester Buses [2011] EWCA Civ 1384.

Dispute resolution

The GTA provides a Technical Committee process for resolving protocol-level disputes between subscribers. The Technical Committee is not a court, its decisions bind the parties as a matter of protocol membership, not law. For substantive disputes that go to litigation, the protocol provides a structured pre-action process that complements the Pre-Action Protocol for the Resolution of Personal Injury Claims and the Pre-Action Protocol for Road Traffic Accidents.

How CreditHire Assist helps

The platform tracks the current GTA version and rates and applies them automatically when generating responses to subscribing TPIs. The TPI Correspondence Analyzer flags GTA-protocol breaches in insurer letters (rate cuts at non-applicable categories, late-payment defences, intervention non-compliance). Outputs are grounded in the GTA version applicable to the date of hire, no version-drift.
