A serious personal injury claim is not simply about negotiating a figure with an insurance company. It can involve years of medical evidence, rehabilitation, care assessments, financial calculations and detailed planning for the injured person’s future.
A recent High Court judgment demonstrates why these cases must be prepared realistically from the outset, particularly where serious injury compensation claims and life-changing injury claims involve long-term care needs, catastrophic injuries and complex expert evidence.
In Bassey v Whittaker and Watford Insurance Company Europe Ltd [2026] EWHC 2126 (KB), the claimant had suffered extremely serious injuries after being struck by a car. Liability was admitted, but the claim still required extensive work to determine the appropriate amount of compensation.
The case concerned legal costs rather than the value of the claimant’s injuries. Nevertheless, it provides an important illustration of the complexity behind a substantial personal injury claim and the danger of failing to anticipate the work that may be required, including the importance of costs budgeting in personal injury cases, particularly in catastrophic injury claims and serious road traffic accident injury claims.
What Happened in Bassey v Whittaker?
The injured claimant was a protected party who lacked the capacity to conduct the litigation himself. His wife acted as his litigation friend.
The claim involved numerous medical and non-medical experts, rehabilitation evidence, continuing disclosure of treatment records, witness statements and a trial estimated to last ten days.
The claimant’s original costs budget sought almost £2 million. Following costs management by the court, the recorded budget was approximately £1.03 million.
As the case progressed, the timetable changed. Further expert work, rehabilitation evidence, updated statements and additional disclosure were required. The claimant applied to increase the approved costs budget by £238,350.
The High Court held that the budget could not be increased simply because more work had arisen or because an increase might appear fair. Under CPR 3.15A, a significant development in the litigation was ordinarily required before an approved costs budget could be revised.
The court concluded that the additional work relied upon had been reasonably foreseeable when the original budget was prepared.
The full decision is available in the approved High Court judgment in Bassey v Whittaker.
What Is a Costs Budget?
In substantial civil claims, each party may be required to provide the court with a budget estimating the legal work and costs likely to be incurred during the proceedings.
The budget is divided into stages, which can include:
- Preparing statements of case.
- Disclosure of documents.
- Witness evidence.
- Medical and other expert evidence.
- Case management hearings.
- Settlement discussions.
- Preparation for trial.
- Attendance at trial.
The court may approve or revise the proposed figures. Once a costs-management order has been made, the approved budget becomes an important control over the costs that may ultimately be recovered from the losing party.
A costs budget is separate from the compensation claimed by the injured person. It does not determine the value of the injuries, care needs or financial losses. However, it governs the recoverable expense of performing the legal work needed to establish those losses and is a central feature of costs budgeting in personal injury cases, especially in serious injury claims and life-changing injury compensation claims.
What is a “Significant Development”?
CPR 3.15A provides a mechanism for revising a costs budget when a significant development in the litigation warrants a change.
The High Court confirmed that, unless the parties validly agree otherwise, a significant development is a necessary threshold. The court does not have a general discretion to increase a budget merely because the original estimate has proved insufficient.
Whether something amounts to a significant development depends on the circumstances. The court will consider whether the event was reasonably foreseeable when the earlier budget was approved.
In Bassey, matters such as further medical evidence, developments in rehabilitation, updated witness statements, additional records and a delayed trial were regarded as reasonably foreseeable features of that particular serious injury claim and catastrophic injury compensation case.
The decision does not mean that further expert evidence or a change in prognosis can never justify a revised budget. A genuinely unexpected development may cross the threshold. The difficulty is that the solicitor must demonstrate why it could not reasonably have been anticipated earlier.
Why Are Serious Injury and Life-Changing Injury Claims So Complex?
Life-changing injury claims often develop over a considerable period. An injured person’s long-term prognosis may not be clear for months or even years.
Evidence may be required from specialists in:
- Neurology or neurosurgery.
- Orthopaedics.
- Neuropsychology and psychiatry.
- Pain medicine.
- Rehabilitation medicine.
- Nursing and professional care.
- Occupational therapy.
- Physiotherapy.
- Accommodation and property adaptation.
- Assistive technology.
- Employment and earning capacity.
- Pensions and financial management.
The legal team may also need to investigate future care, specialist equipment, adapted accommodation, loss of earnings and the effect of the injury upon the claimant’s family.
Life Changing Injuries
Our guide to life-changing injury claims explains the different forms of practical and financial support that may form part of a substantial compensation claim, including catastrophic injury compensation awards and long-term care funding. You may also find our guide on rehabilitation funding in personal injury claims helpful in understanding how early treatment and support can be secured in serious injury and catastrophic injury cases.
Why Early Planning Matters to the Injured Person
Costs budgeting may appear to be a technical dispute between solicitors and insurers. Behind it lies a much more important question: has the claim been properly planned?
A solicitor conducting a serious injury claim or life-changing injury compensation claim should consider at an early stage:
- Which medical disciplines are likely to be relevant.
- Whether the prognosis is sufficiently settled.
- What rehabilitation and treatment evidence will be required.
- Whether the claimant’s care needs are likely to change.
- Whether adapted accommodation will be necessary.
- How employment, pension and future earnings losses should be calculated.
- Whether family members should provide evidence about care and daily life.
- What records will require continuing disclosure.
- Whether interim compensation payments should be requested.
- Whether the litigation timetable is realistic.
If substantial work is omitted from the original budget because it was foreseeable but overlooked, the court may refuse to allow an increase later.
That does not necessarily prevent the injured person from continuing the claim, nor does it automatically reduce their damages. It can, however, create a serious dispute over who must bear the additional legal expense. Proper preparation protects both the claim and the client in serious injury and life-changing injury litigation.
What if the Future Is Still Uncertain?
Some serious injury claims and catastrophic injury claims cannot safely be budgeted to conclusion at an early stage. The claimant may still be receiving intensive rehabilitation, awaiting surgery or undergoing assessment of their long-term capacity and care needs.
In appropriate circumstances, the legal team may ask the court to approve only part of the future budget and direct a later review. This is sometimes more realistic than attempting to predict every stage of a complex case before the medical position becomes clear.
If a genuinely unforeseen development occurs, an application to revise the budget should be made promptly. Waiting until the additional costs have already been incurred may significantly weaken the application.
The High Court also confirmed that a party may attempt to establish a “good reason” to depart from the approved budget at detailed assessment. However, the judgment described that route as an “uphill battle”. It is a safety net, not a substitute for careful budgeting in serious injury compensation claims.
Choosing a Serious Injury Solicitor
A life-changing injury claim requires more than knowledge of the basic law. It demands strategic planning, access to appropriate experts and an understanding of how the injured person’s needs may develop over the rest of their life.
The solicitor must investigate not only the immediate injury but also its effect upon:
- Independence and mobility.
- Employment and earning capacity.
- Personal care.
- Family relationships.
- Housing and transport.
- Medical treatment and rehabilitation.
- Future financial security.
Compensation should place the injured person, so far as money can reasonably do so, in the position they would have occupied had the accident not happened. Achieving that objective requires the evidence and likely costs of the case to be considered from the outset in all serious injury and life-changing injury compensation claims.
