Personal injury practice in the UK has been reshaped profoundly in the last decade. The whiplash reforms (effective May 2021), the expansion of fixed recoverable costs to almost all fast-track and an increasing portion of multi-track personal injury work, the OIC Portal, and the Jackson reforms have collectively changed the economics of PI practice — particularly at the volume, low-value end of the market. Firms that thrived on high-volume road traffic accident claims with hourly rate costs recovery have had to adapt or exit.

The practices that have adapted successfully are those that either moved up the value chain into serious injury, clinical negligence, and employer/occupier liability claims where hourly rates and costs recovery remain viable, or invested heavily in process efficiency to make volume portal claims profitable on fixed fees. This guide addresses both models.

The Personal Injury Landscape Post-2021

The OIC Portal and Fixed Small Claims

The Official Injury Claim (OIC) Portal processes road traffic accident soft tissue injury claims worth £5,000 or less in damages, where the accident occurred on or after 31 May 2021. In these cases, the claimant is expected to navigate the portal largely without legal assistance — the fixed tariff for soft tissue injuries (set by the Whiplash Injury Regulations 2021) replaced the previous flexible general damages, and legal costs in the small claims track are not recoverable.

For law firms, this means that the lowest-value whiplash claims are essentially no longer viable as a fee-earning service unless the firm has found a way to operate at a cost base that makes the modest fixed fees workable. Many firms have moved their intake threshold upwards to £5,000-£7,500 to ensure that matters proceed on the fast track with recoverable costs.

Fast Track and Fixed Recoverable Costs

The Civil Procedure Rules’ fixed recoverable costs (FRC) regime was extended to virtually all fast-track personal injury matters (claims up to £25,000) from 1 October 2023 under Lord Justice Jackson’s recommendations. The FRC tables specify the recoverable costs at each stage of the claim depending on the claim value band and the point at which the case settles.

Understanding the FRC tables in detail is now a core commercial skill for PI solicitors. A claim that settles at the issue stage recovers different costs from one that settles after witness statements, and different again from one that reaches trial. Decisions about when to issue, when to obtain expert evidence, and when to push for trial are partly legal and partly financial — the fee earner needs to understand where on the FRC table a given settlement moment sits.

The Pre-Action Protocol for PI Claims

CNF and Portal Claims

For fast-track RTA, employer liability, and public liability claims, the pre-action process is governed by the relevant Pre-Action Protocol and (for RTA claims valued between £1,001 and £25,000) by the MOJ Claims Portal. The Claim Notification Form (CNF) must be submitted within the protocol timetable; defendants have strict response deadlines.

Managing a large volume of portal claims requires a systematic approach to CNF preparation and submission. Each CNF must accurately describe the accident circumstances, identify the defendant’s insurer, describe the injuries, and indicate the financial value of the claim. A CNF that is inaccurate or incomplete creates delay and can prejudice the claim.

Portal matter management requires tracking: CNF submission dates, response deadlines (acknowledgement and full response), medical evidence commissioning, MedCo allocation and report receipt, Part 36 offers, and settlement negotiations. Each of these has regulatory timeframes; missing them results in the matter exiting the portal and losing the costs protections the portal provides.

Medical Evidence

Medical evidence is the backbone of a personal injury claim. For soft tissue injury claims in the portal, MedCo-registered medical experts must be instructed. MedCo’s random allocation system was introduced to address concerns about expert capture; solicitors must use the MedCo portal to obtain a randomly allocated expert rather than selecting a preferred expert.

For more complex injuries — fractures, psychological injury, chronic pain, neurological damage — specialist experts outside MedCo are required. The solicitor’s selection of the appropriate expert discipline, and the quality of the letter of instruction, directly affects the quality and utility of the report.

The key operational discipline with medical evidence is timeline management. The medical report triggers a response from the defendant (who may rely on it or seek their own evidence), which then informs settlement negotiations. Delays in obtaining medical evidence translate directly into delays in settlement and, in cases with FRC, unnecessary costs on both sides.

Serious Injury and High-Value Claims

Clinical Negligence

Clinical negligence is a separate specialism with its own pre-action protocol, its own expert requirements (a letter of notification to the defendant health body before any proceedings, a duty of candour response), and its own economics. Legal aid is still available for clinical negligence where the claimant qualifies financially and the claim exceeds the threshold value — this is now one of the few areas of personal injury where LAA funding remains in scope.

Clinical negligence requires instruction of medical experts in the specific specialty at issue, often a liability expert (to address the breach of duty question) and a causation expert (to address the link between the breach and the damage suffered). These experts are expensive and their availability can be a bottleneck — building relationships with a reliable panel of clinical negligence experts across the key specialties is a competitive advantage.

The NHS Resolution (formerly NHS Litigation Authority) defends clinical negligence claims against NHS trusts. Understanding NHS Resolution’s approach to early settlement, their use of collaborative resolution for lower-value claims, and the Pre-Action Protocol’s disclosure obligations significantly affects how claims are run.

Fatal Accidents

Fatal accident claims under the Fatal Accidents Act 1976 and the Law Reform (Miscellaneous Provisions) Act 1934 are among the highest-value personal injury instructions. They involve statutory dependency claims for dependants, bereavement awards (currently £15,120 for qualifying dependants following 2020 uplift), and the estate’s own claim for the deceased’s losses before death.

The interaction between a fatal accident claim, probate, and life insurance creates complex coordination requirements between the litigation team, the estate administration team (where the same firm handles both), and any financial advisers. Coordination is needed even in simple cases; in cases where liability is disputed or where there is a significant loss of dependency claim, it is essential.

Funding Personal Injury Claims

Conditional Fee Agreements

CFAs (often called “no win, no fee” arrangements) are the standard funding mechanism for claimant personal injury work. The solicitor agrees to take the case at no upfront cost to the client; if the case succeeds, the solicitor recovers their costs from the defendant (under the FRC regime) and is entitled to a success fee from the client’s damages.

The success fee deduction from damages is capped at 25% of the claimant’s general damages and past special damages (not future losses), under the rules introduced by LASPO 2012. Clients must be given clear written information about the success fee percentage and the effect on their damages recovery before signing a CFA.

After the Event Insurance

ATE (After the Event) insurance protects the claimant against the risk of an adverse costs order if the case is lost. In most fast-track personal injury cases, ATE is now standard. The ATE premium is not recoverable from the defendant (post-LASPO) and must be paid by the client from damages if the case succeeds, or is typically waived by the insurer if the case is lost.

Selecting an appropriate ATE product for each matter type — different products cover different risk profiles, and staged premium ATE (where the premium increases as the case progresses) is often preferable for uncertain-liability cases — is part of competent PI practice management.

Litigation Funding and Panel Arrangements

Panel Agreements with Insurers and Unions

Many PI practices receive referrals from trade unions, insurance companies (for accident victims under own-damage insurance policies), or claims management companies. These referral arrangements come with obligations — typically panel agreements that specify service standards, reporting requirements, and sometimes price structures that differ from the firm’s standard rates.

Panel agreement compliance is an operational management task. Ensuring that all fee earners handling panel referrals understand the specific reporting obligations (and that those obligations are documented in the matter from day one) prevents the complaints and delistings that can follow panel breaches.

Technology for Personal Injury Practices

Portal Integration and Case Management

The MOJ Claims Portal and the OIC Portal are the operational infrastructure of high-volume PI practice. Case management software that integrates directly with these portals — submitting CNFs, logging responses, tracking deadlines — eliminates the manual re-entry work that creates errors and inefficiency.

For serious injury cases outside the portal, case management software with strong document management, expert instruction tracking, and costs budgeting capabilities is essential. The same FRC management challenge that applies to fast-track cases applies more acutely to multi-track cases where costs budgeting under CPR Part 3 is required.

Medical Scheduling and Expert Management

A dedicated system for managing medical appointments, expert instructions, MedCo allocations, and report receipt significantly reduces the overhead of medical evidence management. For high-volume practices, this can be a module within the case management system; for specialist serious injury practices, a bespoke expert panel management tool may be preferable.

Obiter supports personal injury teams with the correspondence and administrative layer that high-volume claims generate — reading and triaging incoming insurer correspondence, drafting client update letters, recording billable time from calls and portal interactions, and maintaining AML records. For practices handling hundreds of portal and fast-track matters simultaneously, having AI manage the routine communication workflow frees up fee earners for the medical and legal analysis that drives settlement value.
