Detailed Assessment of Costs (CPR Part 47)
- Mar 10
- 4 min read

Bills of Costs, Points of Dispute, Proportionality and Detailed Assessment Strategy
Detailed assessment proceedings are often the stage where litigation costs exposure is either significantly reduced or successfully recovered.
Where parties cannot agree the amount of costs payable following a costs order, the court may determine the recoverable costs through detailed assessment under CPR Part 47.
For paying parties, the process is an opportunity to:
challenge excessive costs
reduce exposure
dispute hourly rates
raise proportionality arguments
challenge unreasonable or unnecessary work
For receiving parties, detailed assessment is critical to:
maximising recovery
defending reductions
justifying rates and time claimed
responding effectively to Points of Dispute
protecting recoverable profit costs and disbursements
SPH Costs acts for both paying and receiving parties across England & Wales in detailed assessment proceedings, including:
insurers
local authorities
defendant organisations
claimant firms
Court of Protection practitioners

What Is Detailed Assessment?
Detailed assessment is the court process used to determine the amount of legal costs recoverable following litigation.
The process usually arises where:
a costs order has been made
proceedings settle without costs agreement
interim costs orders are disputed
parties cannot agree the level of recoverable costs
The receiving party serves a Bill of Costs setting out the costs claimed.
The paying party may then serve:
Points of Dispute
identifying the reductions sought and the basis for challenge.
The receiving party may respond with:
Replies to Points of Dispute
before the matter proceeds toward provisional assessment, negotiation or an oral detailed assessment hearing.
Facing a Bill of Costs?
For paying parties, detailed assessment proceedings frequently involve disputes concerning:
excessive hourly rates
duplication of work
proportionality
counsel’s fees
expert fees
fee earner delegation
unnecessary attendances
inflated electronic bills
Well-drafted Points of Dispute often determine whether exposure is significantly reduced before any hearing takes place.

Maximising Recovery at Detailed Assessment
For receiving parties, detailed assessment strategy is equally important.
Poorly structured Bills of Costs, weak Replies or procedural failures can result in substantial reductions even where the underlying litigation succeeded.
Receiving party disputes commonly concern:
reductions to hourly rates
proportionality challenges
criticism of staffing levels
disputes concerning incurred time
challenges to counsel’s fees
recoverability of disbursements
Careful preparation of:
Bills of Costs
Replies
supporting evidence
schedules
narrative explanations
can materially affect the outcome of assessment proceedings.
The Main Stages of Detailed Assessment Proceedings
Detailed assessment proceedings usually involve:
Preparation and service of the Bill of Costs
Service of Points of Dispute
Replies to Points of Dispute
Negotiation between the parties
Provisional assessment or oral hearing
Many disputes resolve through negotiation once the key issues are identified clearly within the Points of Dispute and Replies.
Bills of Costs
The Bill of Costs sets out:
the work undertaken
time claimed
hourly rates
disbursements
VAT
funding information
The structure and presentation of the Bill frequently influence:
negotiation strategy
proportionality arguments
settlement prospects
the scope of disputes at assessment
Electronic bills and phased bills now play an increasingly important role in higher-value litigation and costs budgeting disputes.
Points of Dispute
Points of Dispute are the paying party’s primary mechanism for reducing costs exposure. Weak, generic or poorly targeted challenges frequently result in unnecessary costs being allowed.
Effective Points of Dispute usually focus on:
proportionality
unreasonable time claimed
excessive hourly rates
duplication
lack of delegation
excessive attendances
unnecessary work
non-recoverable items
Specialist drafting often materially affects both:
settlement negotiations
final recoverable costs
For practical guidance see:
Replies to Points of Dispute
Replies are the receiving party’s opportunity to defend:
work undertaken
rates claimed
staffing structures
litigation strategy
proportionality
recoverability
Strong Replies frequently narrow disputes significantly before any hearing takes place.
Weak Replies may leave substantial reductions difficult to resist later during assessment proceedings.
Hourly Rates and Guideline Hourly Rates
One of the most common areas of dispute concerns solicitor hourly rates.
Courts frequently consider:
Guideline Hourly Rates
complexity of litigation
seniority of fee earners
location of the practice
conduct of the litigation
Disputes commonly arise where:
rates exceed guideline levels
Grade A/B fee earners conducted routine work
delegation between fee earners is challenged
the complexity of the case is disputed
Proportionality
Even where individual items are reasonably incurred, the court must still consider whether the total costs claimed are proportionate.
Proportionality arguments are often central to detailed assessment proceedings.
The court may consider:
the value of the claim
complexity
conduct
importance of the litigation
wider factors affecting the proceedings
For paying parties, proportionality may provide a powerful route to reducing overall exposure. For receiving parties, careful presentation of the litigation context is frequently essential.
Provisional Assessment
Many detailed assessments proceed initially by provisional assessment
This paper-based process involves the court reviewing:
the Bill of Costs
Points of Dispute
Replies
supporting documents
without an oral hearing.
The court then issues a written provisional assessment. Where either party disputes the provisional outcome, the matter may proceed to an oral detailed assessment hearing.
Oral Detailed Assessment Hearings
Some disputes require oral hearings before a Costs Judge.
Common disputes include:
hourly rates
proportionality
counsel’s fees
electronic bills
procedural compliance
staffing structures
recoverability arguments
Preparation before oral assessment is often critical to the final outcome.
Detailed Assessment Strategy Matters Early
Detailed assessment outcomes are rarely determined solely at the hearing stage.
The approach taken during the litigation itself frequently affects:
recoverability
proportionality arguments
drafting strategy
settlement prospects
evidential support
Early costs strategy is therefore important for both:
paying parties seeking to reduce exposure
receiving parties seeking to maximise recovery
