Electronic Bills of Costs: Structure, Precedent H Alignment and Detailed Assessment
- 4 days ago
- 3 min read

Electronic bills of costs are now standard in multi-track litigation and require a structured approach to preparation and assessment. The phase, task and activity format is designed to mirror Precedent H and enables detailed comparison between the approved budget and the costs claimed. Understanding how electronic bills operate is essential for both receiving and paying parties involved in detailed assessment.
What Is an Electronic Bill of Costs?
An electronic bill of costs presents time in a spreadsheet format organised by phases, tasks and activities. This structure allows the work undertaken to be analysed and compared directly with the approved costs budget.
The objective is transparency so that the court and the parties can identify what work was carried out, by whom and at what stage of the litigation.
Phases, Tasks and Activities
Electronic bills are designed to reflect the structure of Precedent H:
phases correspond to the stages of litigation
tasks identify the type of work undertaken
activities describe the specific action performed
This format allows the bill to be reviewed alongside the approved budget and its assumptions.
Relationship with Precedent H
The approved costs budget remains the starting point on detailed assessment. Time recorded within each phase of the electronic bill should correspond with the phases and assumptions contained in Precedent H.
Where work falls outside those assumptions, the court will consider whether there is good reason to depart from the approved budget.
Common Issues in Electronic Bills
Issues that frequently arise on detailed assessment include:
time recorded in an incorrect phase
inconsistent task descriptions
block billing within activities
duplication of attendances
excessive senior fee earner time on routine work
work claimed outside the scope of the budget assumptions
These matters may affect both the presentation of the bill and the assessment of recoverable costs.
Analysis on Detailed Assessment
A structured review of an electronic bill involves:
comparing phase totals with the approved budget
identifying work that does not fall within the budget assumptions
analysing time by task and fee earner grade
considering proportionality within each phase
This phase-based approach assists the court in determining whether the costs claimed are reasonable and proportionate and should be considered alongside proportionality challenges in costs.
Points of Dispute and Electronic Bills
Effective points of dispute and replies to an electronic bill should address:
alignment between the bill and Precedent H phases
clarity of task and activity descriptions
time recorded outside the approved scope
delegation and fee earner grade
Addressing these matters at phase level as well as by individual entry supports a structured detailed assessment.
Requests for Re-presentation
Where an electronic bill does not allow proper comparison with the approved budget, it may be necessary to request re-presentation. This can arise where:
phases do not correspond with Precedent H
task and activity information is unclear
time cannot be reconciled with the budget
A properly structured bill assists both the court and the parties during detailed assessment.
J-Codes and Bill Structure
The use of J-Codes is not mandatory. The critical requirement is that the bill presents time in a clear phase and task format that allows comparison with the approved budget.
The focus on detailed assessment is therefore on transparency and structure rather than the coding system used.
Preparing Electronic Bills
For receiving parties, careful preparation of the electronic bill includes:
ensuring phase totals match the approved budget
using clear task and activity descriptions
maintaining consistency between time records and the bill
aligning the bill with the Precedent H assumptions
This assists the court and reduces the likelihood of queries on detailed assessment.
Assessing Electronic Bills
For paying parties, a structured review of the electronic bill enables:
comparison with the approved budget
identification of work outside scope
analysis of fee earner grade and delegation
consideration of proportionality by phase
This supports a focused and efficient approach to detailed assessment and the preparation of points of dispute and replies.
