What CPR 45.29 Actually Does

Under the current Civil Procedure Rules, including CPR 45.29, many Fast Track claims (and certain Part 8 proceedings) fall within a fixed recoverable costs regime.

The regime:

• caps recoverable costs at defined litigation stages

• limits recoverable fees (pre-action, issue to trial, trial)

• fixes recoverable amounts except in limited circumstances

Its objectives are:

✔ procedural certainty

✔ proportionality

✔ easier assessment

✔ predictability of exposure

However, fixed costs are not the end of the matter. Disputes still arise where:

• work lies outside the fixed regime

• exceptional factors are alleged

• proportionality and conduct arguments arise

• paying parties challenge entitlement at detailed assessment

The Core Rule Framework

CPR 45.29 remains central to the Fast Track fixed costs regime. In practice:

• fixed tables apply to specified stages

• recoverable sums are capped

• departure requires justification

Although this post originated before later consolidations of the CPR, it reflects the regime as applied in modern assessment practice.

Why Fixed Costs Disputes Still Arise

Fixed costs reduce argument — they do not eliminate it. Disputes commonly arise where:

1. Work Falls Outside the Fixed Scope

Issues often concern:

• specialist expert evidence

• additional hearings

• complex interlocutory steps

• work beyond standard Fast Track progression

Paying parties argue such work does not fall within the fixed scheme.

2. Exceptional Case Factors

The rules allow departure where exceptional factors justify it. The dispute becomes factual:

• Was the case truly exceptional?

• Does evidence support that status?

• Were costs actually incurred in that exceptional phase?

3. Proportionality and Conduct

Even within a fixed regime, disputes often involve:

• proportionality

• whether work was reasonably necessary

• whether conduct increased costs beyond what the tables assume

How Paying Parties Challenge Fixed Costs Claims

Effective challenges move beyond rule citation into dispute mechanics.

Ground A – Narrow Scope Interpretation

Paying parties argue:

• certain items fall outside the fixed scheme

• entitlement does not arise under the tables

• the work is of a type not envisaged

Ground B – Exceptional Factors Not Proven

Where exceptional circumstances are alleged, challenges focus on:

• lack of supporting evidence

• routine rather than exceptional context

• failure to meet the regulatory threshold

Ground C – Proportionality and Necessity

Arguments often show:

• costs disproportionate to value or complexity

• steps not typical in comparable Fast Track matters

• unnecessary or inefficient work

This is frequently the most strategic challenge.

The Role of Detailed Assessment

Even where CPR 45.29 applies, entitlement is tested at detailed assessment. Disputes may concern:

• scope of fixed tables

• exceptional costs

• proportionality

• conduct increasing costs

Advising on fixed costs therefore involves dispute planning, not simply reporting the rule.

Common Mistakes Leading to Reductions

Reductions often arise where parties:

• assume all work is covered

• fail to evidence exceptional factors

• overlook proportionality

• do not explain why costs were reasonably incurred

When Can Parties Argue Fixed Costs Do Not Apply?

Disputes often centre on whether CPR 45.29 governs the case at all.

Cases Outside Scope

Arguments arise where:

• the claim does not fall within the relevant pathway

• the case developed beyond what the regime anticipated

• case management altered complexity

• proceedings moved outside required conditions

Complexity and Case Development

While complexity alone is insufficient, disputes may arise where:

• factual or expert issues expanded significantly

• additional procedural steps occurred

• party conduct altered case trajectory

These often overlap with proportionality arguments.

Procedural Conduct and Case Management

Relevance may arise where:

• directions altered the nature of the claim

• atypical hearings occurred

• the procedural history diverged from standard Fast Track progression

Overlap With Other Costs Arguments

Scope disputes often intersect with:

• indemnity costs arguments

• guideline hourly rate challenges

• proportionality assessments

Why This Matters

Whether a case falls within fixed recoverable costs can dramatically affect financial exposure. Early identification of scope issues and procedural strategy reduces dispute risk at assessment.

Key Takeaways

• CPR 45.29 sets the fixed regime, but disputes remain common

• Fixed costs are not inviolable

• Paying parties succeed through scope, exception and proportionality challenges

• Evidence at detailed assessment is critical

• Understanding interpretation in disputes improves exposure control
