A step-by-step guide to the Official Injury Claim portal
What happens at each stage, what to watch for, and where decisions can affect what you receive.
Who this process is designed for
The Official Injury Claim portal handles a specific type of claim. Understanding whether it applies to your situation is the first thing to check.
Most people go through this process once — and it is not always clear what matters or what to expect. This guide covers what actually happens at each stage, what to watch for, and where the decisions that affect your outcome actually sit.
The Official Injury Claim (OIC) portal is designed for straightforward road traffic accident claims in England and Wales, typically involving whiplash or soft tissue injuries valued under £5,000 in injury damages. It was built so that claimants could manage the process themselves, without a solicitor.
If your situation is more complex — multiple injuries, disputed liability, or ongoing symptoms — the process may involve additional steps or considerations. You can still read through the stages below to understand how it works before deciding how to proceed.
Drivers and passengers injured in road traffic accidents in England and Wales on or after 31 May 2021, where the accident was not their fault (or where fault is disputed), and where the injury damages are valued under £5,000. The claimant must be aged 18 or over and the other vehicle must be identifiable and insured.
Cyclists, motorcyclists, pedestrians and horse riders cannot use the OIC portal — their claims follow a different process with different rules around legal costs. Children under 18 at the time of the accident are excluded, as are accidents involving uninsured or untraced drivers, or vehicles registered outside the UK.
Step by step: what happens when you make an OIC claim
The process follows four main stages. Understanding these makes everything else easier to navigate.
You submit basic information about the accident — the date, the vehicles involved and your injuries. The portal notifies the at-fault insurer, who then has 30 working days to respond with a liability decision. The claim is verified by a Statement of Truth: a formal declaration that the information provided is accurate.
What to watch for
The accident date determines which tariff applies — different rates have been in place since May 2025. It is also easy to understate symptoms at this stage, particularly if they developed or changed in the days after the accident.
Pause and check
Review everything before submitting. This is a formal declaration — take a moment to check everything carefully before proceeding. Providing inaccurate information in a Statement of Truth can have serious consequences.
The insurer admits liability in full, admits partial liability, or denies it. A full or partial admission moves the claim forward to the medical stage. A denial can be challenged through the portal or escalated to the small claims court.
What to watch for
A denial is not the end of a claim. But navigating a liability dispute — understanding what the denial turns on, gathering the right evidence — is where the difference between having representation and managing alone becomes most significant.
Pause and check
If liability is denied, read the insurer's reason carefully. If it is unclear or you believe it is incorrect, do not accept it without understanding your options.
An independent medical examination is arranged through MedCo — the accredited medical reporting organisation. The examiner produces a report assessing your injuries and expected recovery period. The prognosis period recorded in that report directly determines your tariff value — it is the single most consequential document in the process.
What to watch for
It is easy to understate symptoms at a medical appointment — particularly if they changed over time or affected day-to-day activities in ways that are hard to articulate. Think about how your daily life was affected, not just the initial injury.
Pause and check
Read the draft report carefully before approving it. If it does not accurately reflect your experience — the duration of symptoms, the effect on daily life — you can raise this before it is submitted. Once approved, it forms the basis of the settlement offer.
Once an offer is requested, the insurer has 20 working days to respond. The offer is calculated from the tariff based on the prognosis period in the medical report. Financial losses — travel costs, lost earnings, treatment expenses — can also be included. Counter-offers are made through the portal.
What to watch for
The first offer is often not the final outcome. The portal has a counter-offer mechanism — it is designed to be used. Consider whether all elements of your claim have been included before deciding.
Pause and check
Before accepting, check the tariff figure against what your prognosis period should produce. If financial losses have not been included, raise them before accepting. Acceptance through the portal is binding — the claim cannot be reopened after this point.
What the official guides do not always make clear
The OIC portal is presented as simple and straightforward. The experience of using it is often more involved. These are the things worth knowing before you start.
Claims through the OIC portal can take several months to resolve. OIC data shows an average of around 350 days from submission to settlement. This is not a sign that something has gone wrong — it is how the process is structured. Each stage follows on from the previous one, and the timeline runs at the pace of the insurer's decisions and medical appointment availability.
What helps
Keep track of key dates and portal communications. Knowing the timescales in advance removes much of the uncertainty during the waiting periods.
Around 87–88% of OIC claims are submitted with some form of professional representation — far above what the system's designers projected. Many claimants find the steps, terminology and decision points more involved than the official description suggests.
What helps
Take time to understand each step before acting on it. If something is unclear, pause. The complexity that deters most people is mostly definitional — once the structure is clear, the process is navigable.
Where more than one injury is involved — a whiplash alongside a knee or wrist injury, for example — the claim does not fit neatly within the tariff structure. This affects a significant proportion of claims and can create uncertainty about valuation and process.
What helps
Make sure all symptoms are recorded and reflected in your medical report. If multiple injuries are involved, understand how this affects the process before proceeding.
When it is worth slowing down
Some situations within the OIC process create complications the portal is not well-designed to handle. These are the points where pausing — and in some cases seeking regulated legal advice — makes a material difference.
If any of the following apply, take time to understand the implications before proceeding: your symptoms are ongoing or getting worse; you do not fully understand the medical report before approving it; liability is disputed or denied; multiple injuries are involved; the claim value may be approaching £5,000 in injury damages or £10,000 in total; you are unsure whether to accept an offer. Pausing does not mean you have done anything wrong. It is part of making an informed decision.
A mixed injury claim is one where the claimant has suffered both a whiplash or soft tissue injury (covered by the tariff) and a separate non-whiplash injury — a knee injury, a wrist injury, a fractured rib, a psychological diagnosis. These are not edge cases. In the final quarter of 2024, approximately 69% of OIC claims involved mixed injuries.
The portal was designed primarily for whiplash-only claims. Non-tariff elements do not have a fixed valuation mechanism within the OIC process. This creates uncertainty about how to value them, how to negotiate them and when a claim has outgrown the portal entirely. ACSO estimated in March 2025 that approximately 500,000 mixed injury claims were stuck in the portal — neither settled nor formally escalated.
Where the insurer denies liability or alleges that the claimant was partly at fault, the OIC process provides limited tools. The claimant can submit evidence, respond to the insurer's position and use the portal's messaging system — but if the dispute cannot be resolved, the next step is the small claims court. The portal itself cannot determine fault.
Navigating a liability dispute — gathering the right evidence, understanding what the denial actually turns on, presenting the case effectively — is where the gap between having representation and managing alone becomes most significant. This is the clearest situation in which regulated legal advice is relevant from the outset.
The OIC portal handles claims where injury damages are under £5,000. A whiplash injury with a prognosis of 18–24 months currently attracts £4,830 under the tariff alone — just below the threshold. Once financial losses are added, many claims exceed £5,000 in injury value or £10,000 in total.
Where a claim's total value exceeds £10,000, it exits the portal. Claims in this range can have substantially different outcomes outside the OIC process, because the tariff no longer applies and the claim is assessed under different rules. Settling within the OIC without recognising that the claim may belong outside it is one of the clearest ways value is lost through process rather than negotiation.
The OIC tariff for minor psychological injury covers prognosis periods of up to 12 months only. Beyond 12 months, the tariff structure does not apply to psychological injuries. A formal diagnosis of PTSD or clinically significant psychological injury also falls outside the portal framework entirely.
These cases involve a level of complexity the standard OIC process was not designed to accommodate. They are situations where the portal may not be the appropriate process, and where regulated legal advice is relevant from the outset.
What happens after your claim is submitted
Once your claim is underway, much of the process involves waiting. During this time, what you record and how you respond still matters.
Progress can feel slow and uneven after you submit your claim. The process routinely takes longer than people expect — not because something is wrong, but because the timescales are built into the protocol and each stage follows on from the previous one. A claim submitted today is unlikely to settle for the better part of a year. This is the normal experience. Understanding it from the outset removes a significant source of anxiety during the waiting periods.
During this period, a few things remain within your control. Keep notes of any changes in symptoms — improvements and setbacks both. If symptoms change significantly after the medical examination, there may be a mechanism to address this before the final report is approved. Respond to portal notifications promptly: some steps have fixed response windows and missing them can create complications. Keep copies of all documents and communications. If progress appears to have stalled, you can send a message through the portal to request an update.
If the process feels slow or unclear, that is a common experience — not an indication that something has gone wrong. The claim timeline maps the stages against typical real-world timescales and explains what the 350-day average actually reflects.
Most claimants do not complete the process alone
Since the portal launched in May 2021, approximately 87–88% of claims have been submitted with some form of professional representation — solicitors, claims management companies or insurers' own panel firms. This is far above the government's projected rate of around 30%.
The Justice Select Committee described the low rate of self-represented claimants as raising "serious concerns about the accessibility and user-friendliness of the OIC process." The government's post-implementation review of the Whiplash Reform Programme — which concluded its evidence-gathering in December 2025 — reached similar conclusions; its findings are expected in Spring 2026.
This is not a reason to feel defeated by the process.
The complexity that deters most people is mostly definitional — once the terminology, timescales and structure are clear, the process is navigable. Understanding what happens at each stage is the most effective preparation for going through it.
One further finding from the OIC's own published data: for straightforward whiplash claims, unrepresented and represented claimants have agreed similar levels of compensation. The tariff is fixed by government regulation — a solicitor cannot negotiate a higher tariff figure than the medical report supports. Their ability to influence the outcome in a straightforward claim is limited to the same things a well-informed claimant can also do: ensure the medical report is accurate, include all financial losses, and use the counter-offer mechanism.

Important — limitation period
Starting a claim through the OIC portal does not stop the three-year limitation period.
Only issuing court proceedings stops the clock. If your claim is approaching the three-year deadline, this creates a critical risk — because once the limitation period expires, the ability to continue the claim is usually lost.
Why the process feels the way it does
Understanding the fundamental tension in the OIC's design is the single most useful piece of context for anyone going through the process.
The OIC was designed to reduce the cost of processing minor injury claims — primarily for insurers, and by extension (in theory) for motorists through lower premiums. It was also designed to be usable without a solicitor. These two objectives are not always compatible. A system optimised for cost reduction produces different design choices than one optimised purely for claimant accessibility.
The fixed tariff removes the uncertainty of judicial valuation — but it also removes the ability to argue that a particular injury deserves more than the band allows. The ban on settling without medical evidence protects against fraudulent claims — but it also means every genuine claimant goes through a formal examination process that takes months. The 30-working-day liability window gives insurers structured time to investigate — but it also means claimants wait six calendar weeks with minimal communication. None of these features are accidental. They reflect deliberate design choices made within a framework whose stated purpose included reducing insurer costs. Knowing this does not change how the process works — but it does make the waiting, the formality and the occasional counterintuitive structure more legible.
This context is not an argument that the OIC is unfair or that the system should not be used. The portal processes hundreds of thousands of claims. The majority settle without incident. The tariff provides certainty about values for the injury type it was designed to cover. What it does mean is that an informed claimant — one who understands what the process is optimised for, where its limitations lie and where the critical decision points are — is better placed to navigate it than one who assumes it was built primarily to serve them. That gap in understanding is what this guide aims to close.
