Detailed Assessment Strategy for Paying Parties

​

If you have been served with a Bill of Costs, Detailed Assessment is the stage where financial exposure is either reduced or unnecessarily increased.

​

As part of our Paying Party Cost service, SPH Costs acts for insurers, local authorities, businesses and other paying parties throughout England & Wales. We provide strategic advice from the initial review of a Bill of Costs through to negotiation, provisional assessment and contested Detailed Assessment proceedings.

Successful outcomes are rarely determined on the day of the hearing. They are usually achieved through early analysis, well-drafted Points of Dispute, effective negotiation and a clear strategy from the outset.

 

What Is Detailed Assessment?

​

Detailed Assessment is the court process used to determine the amount of costs payable where the parties cannot reach agreement. Although the Court considers individual items within the Bill of Costs, the assessment is rarely a simple line-by-line exercise. Instead, the Court considers broader issues including:

​

  • Reasonableness.

  • Proportionality.

  • Recoverability.

  • Conduct during the litigation.

  • Compliance with the Civil Procedure Rules.

 

A carefully planned strategy can therefore have a significant impact on the final outcome.

 

Where Detailed Assessment Outcomes Are Really Decided

​

Many paying parties assume that success depends upon advocacy at the hearing. In reality, the outcome is often determined much earlier. The most significant issues usually include:

​

  • Whether the overall costs claimed are proportionate.

  • Whether hourly rates are reasonable.

  • Whether the level of fee earner claimed is justified.

  • Whether duplication or inefficiency exists.

  • Whether procedural conduct affects recoverability.

  • Whether the <a href="https://www.sphcosts.com/points-of-dispute">Points of Dispute</a> clearly identify the strongest reduction arguments.

 

Strong preparation creates leverage long before the matter reaches the Court.

 

A Structured Strategy for Paying Parties

​

Our approach follows a structured process designed to reduce unnecessary costs exposure.

 

1. Early Review of the Bill of Costs

​

We assess:

  • The value of the claim compared with the costs claimed.

  • Complexity of the litigation.

  • Procedural history.

  • Areas of obvious overstatement.

 

2. Identifying the Strongest Reduction Arguments

​

Typical pressure points include:

  • Excessive hourly rates.

  • Incorrect fee earner grading.

  • Duplication of work.

  • Excessive attendances.

  • Unnecessary correspondence.

  • Costs falling outside the scope of recovery.

 

3. Drafting Effective Points of Dispute

​

Effective Points of Dispute do far more than challenge individual entries. We prepare structured objections supported by:

  • CPR principles.

  • Proportionality.

  • Recoverability.

  • Commercial reduction strategy.

 

4. Negotiation

​

Many Bills of Costs settle before Detailed Assessment. Well-prepared Points of Dispute frequently strengthen the paying party's negotiating position and encourage commercial settlement.

​

5. Detailed Assessment Proceedings

​

Where agreement cannot be reached, we prepare focused arguments supported by evidence, avoiding unnecessary points that may distract from the strongest issues.

​

The Issues We Commonly Challenge

​

Successful reductions frequently arise from recurring issues.

 

Hourly Rates

  • Rates exceeding Guideline Hourly Rates.

  • Incorrect fee earner grading.

  • Unsupported enhancements.

 

See our Guideline Hourly Rates 2026 guide.

​

Delegation and Duplication

​

We regularly challenge:

  • Partner-level work undertaken on routine tasks.

  • Multiple fee earners attending the same meetings.

  • Repeated review of documents.

  • Internal duplication.

 

Proportionality

 

Even where individual items appear reasonable, the Court must still consider whether the overall costs claimed are proportionate.

Global reductions frequently arise where costs are disproportionate to:

  • The value of the claim.

  • The complexity of the litigation.

  • The importance of the proceedings.

 

Recoverability

 

We regularly advise on:

  • Work outside the scope of recovery.

  • Procedural defects.

  • Discontinuance issues.

  • Fixed Costs arguments under CPR Part 45.

 

Counsel's and Expert Fees

 

We also advise on:

  • Counsel's fees.

  • Expert fees.

  • Duplication.

  • Proportionality.

  • Appropriate level of expertise.

 

Why Paying Parties Often Overpay

 

In our experience, unnecessary costs are frequently allowed because:

  • Points of Dispute are generic.

  • Individual items are challenged without an overall strategy.

  • Proportionality arguments are underdeveloped.

  • Negotiation opportunities are missed.

  • Key weaknesses within the Bill are not identified early.

 

Successful Detailed Assessment is about strategy rather than simply objecting to individual entries.

 

Provisional Assessment and Oral Hearings

​

Most Bills of Costs are determined by Provisional Assessment.

This means your written case is often the most important part of the proceedings.

Where matters proceed to an oral hearing, success frequently depends upon:

  • Clearly defined issues.

  • Focused arguments.

  • Strong supporting evidence.

  • Well-drafted Points of Dispute.

 

Detailed Assessment as Part of a Wider Paying Party Strategy

 

Detailed Assessment forms one stage of a wider Paying Party Costs service.

Taken together, these services provide paying parties with a consistent strategy from receipt of the Bill through to final assessment.

 

When Specialist Advice Makes the Greatest Difference

​

Early specialist involvement is particularly valuable where:

  • The Bill of Costs is high value.

  • Hourly rates exceed guideline levels.

  • Delegation or duplication is evident.

  • Proportionality is likely to be an issue.

  • Fixed Costs arguments arise.

  • A contested Detailed Assessment appears likely.

Early review frequently creates opportunities for settlement before the matter reaches a final hearing.
