Criminal legal aid billing is governed by a dense web of regulations, portal-specific requirements, and fee scheme calculations that catch out even experienced criminal defence practitioners. Unlike civil legal aid — where most work is billed on a controlled or certificated basis through CCMS — criminal work splits across multiple portals, remuneration mechanisms, and billing codes. Errors at any stage can result in reduced payment, a requirement to repay, or an adverse finding on audit. This guide explains the billing codes, portals, and best practice for crime lower and crime higher claims.

The Regulatory Framework for Criminal Legal Aid Billing

Criminal legal aid in England and Wales is funded under the Legal Aid, Sentencing and Punishment of Offenders Act 2012 and administered by the Legal Aid Agency under a network of Standard Crime Contracts. Remuneration is set by the Criminal Legal Aid (Remuneration) Regulations 2013, as amended.

The Regulations prescribe how different types of criminal work are remunerated — through fixed fees, hourly rates, or graduated fee calculations depending on the work type, court level, and case characteristics. Understanding which remuneration regime applies to a particular piece of work is the foundation of accurate billing.

The 2022 Fee Increases

Following sustained pressure from the Criminal Bar Association and the Law Society, the Ministry of Justice implemented a 15% increase in criminal legal aid fees in October 2022, applying to both solicitors and barristers. This was the most significant fee increase since the legal aid reforms of the 2000s. The uplift applied across both Crime Lower (police station and magistrates’ court) and Crime Higher (Crown Court) work. Despite this, research commissioned by the Law Society in 2023 confirmed that real-terms rates remained substantially below 2010 levels for many practitioners.

Crime Lower: Police Station Work

Police station advice and assistance is primarily remunerated through a fixed fee regime under the Crime Lower contract.

Police Station Fixed Fees

For Duty Solicitor work at the police station, a standard fixed fee applies per attendance. As of 2025:

Standard police station fixed fee (outside London): £186.05 per matter
Standard police station fixed fee (London): £223.50 per matter

The fixed fee covers attendance at the police station, phone advice, and follow-up work relating to the same matter up to the “escape threshold.” Own client work at the police station (where the detained person is an existing client of the firm rather than a duty-allocated one) is also remunerated at the fixed fee unless the escape threshold is reached.

The Escape Fee Threshold

Where the actual cost of police station work exceeds the fixed fee by a specified multiple (currently three times the fixed fee), the matter “escapes” from the fixed fee regime and is remunerated at hourly rates. This is known as the escape fee threshold.

To claim at hourly rates, the provider must be able to demonstrate that the work genuinely exceeded the threshold. CWA performs automatic checks against the claimed time; matters that are close to but do not reach the threshold are paid at the fixed fee without question. Providers should calculate the threshold before submitting to confirm whether an hourly rate claim is appropriate.

The escape fee hourly rates for crime lower as of 2025 are:

Grade A (London): £59.39/hour
Grade A (outside London): £52.56/hour
Grade B (London): £50.26/hour
Grade B (outside London): £44.46/hour

CWA Billing Codes for Police Station Work

Crime Lower submissions through CWA require the correct combination of:

Matter type codes — identifying whether the matter is Duty or Own Client, and the offence category (there are 14 offence categories in the current Crime Lower contract, ranging from “general crime” through to specified offences including sexual offences, terrorism, and homicide).

Stage reached codes — indicating how far the matter progressed. The stage reached affects the fixed fee payable in some circumstances and is an audit-relevant field.

Outcome codes — recording the outcome of police station attendance (e.g., released without charge, charged and bailed, charged and remanded, NFA). Getting the outcome code wrong is one of the most common audit findings in crime lower work.

Activity codes — where the matter escapes the fixed fee, time is broken down by activity (attendance, travel and waiting, telephone advice, preparation of written advice).

Magistrates’ Court (Crime Lower) Fixed Fees

Representation at the magistrates’ court under the Crime Lower contract is also primarily fixed-fee. The magistrates’ court fixed fee is calculated by reference to:

The offence type (standard or specified)
The stage at which the matter concludes (guilty plea, cracked trial, contested trial, committals to Crown Court)
Whether the matter is “standard” or falls into one of the enhanced fee categories

Standard Matter Fixed Fees (Outside London, 2025)

Guilty plea (standard offence): £332.20
Cracked trial (standard offence): £332.20
Contested trial (standard offence): £490.75 + £89.60 per day beyond the first
Committed to Crown Court: £158.52 (preparation fee, with further fees payable at Crown Court level)

Specified Offences and Enhanced Fees

Specified offences — including drug offences above Class B supply, sexual offences, serious violence, and certain financial crime — attract enhanced fees. The enhancement percentage varies by offence type and stage. Providers should check the Crime Lower contract specification to confirm whether an offence falls into a specified category before coding the matter.

Escape Fees at Magistrates’ Court Level

As with police station work, exceptionally complex magistrates’ court matters can escape from the fixed fee regime. The escape threshold is 3× the applicable fixed fee. Above that threshold, the matter is remunerated at hourly rates (applying the same grade-based rates as for police station escape cases). Documentary evidence of actual time is essential for escape fee claims, as CWA will scrutinise the claimed hours carefully.

Crime Higher: Crown Court Billing

Crown Court work — representation in the Crown Court on indictable and either-way offences — is remunerated under the Litigators’ Graduated Fee Scheme (LGFS) for solicitors and the Advocates’ Graduated Fee Scheme (AGFS) for barristers and in-house advocates.

LGFS: How the Graduated Fee is Calculated

The LGFS fee is not a simple hourly rate or fixed fee — it is a graduated calculation that takes into account:

Case type — Trial, cracked trial, guilty plea, or committed for sentence. A “cracked trial” is one that resolves (by guilty plea or otherwise) after the case is listed for trial but before it begins. Misclassifying a case type is a frequent source of billing disputes.
PPE (Pages of Prosecution Evidence) — The LAA uses the PPE count as a proxy for case complexity and volume of reading. The graduated fee increases with PPE, but only up to specified thresholds; above the threshold, a “PPE bolt-on” applies. The LAA’s own PPE count (drawn from the Digital Case System) governs; where there is a discrepancy, providers should raise it promptly.
Number of defendants — A small uplift applies where there is more than one defendant represented.
Special features — Uplifts apply in certain defined circumstances, including confiscation proceedings, cases with a very large number of witnesses, and Newton hearings that add significantly to the preparation burden.

Common LGFS Billing Errors

Incorrect case type classification. The distinction between a trial and a cracked trial is critical — the fee differential can be substantial. A case is a “cracked trial” if the first day of trial is listed and the case resolves before or on that day; it is a “guilty plea” if it resolves before trial is listed. Cases that resolve at the PCMH (Plea and Case Management Hearing) are guilty pleas, not cracked trials.

Incorrect PPE count. The LAA’s digital PPE count is automatically imported into the LGFS claim, but providers should verify it against their own records. Where prosecution evidence was served in non-standard digital formats (audio, video, CCTV) additional PPE may be claimable.

Missing bolt-ons. Various LGFS uplifts (“bolt-ons”) must be claimed explicitly and are not automatically applied. These include the confiscation bolt-on, the very high cost case (VHCC) bolt-on, and the Paper Heavy Case Uplift (PHCU). Failure to claim bolt-ons is a recoverable loss for the firm.

Not claiming disbursements. Travel, accommodation, and expert fees must be claimed separately from the graduated fee. Many firms focus on the graduated fee calculation and overlook legitimate disbursements.

Using CWA for Crime Lower Submissions

The Contract Work and Administration (CWA) portal is the submission gateway for crime lower claims. Key practice points:

Matter Starts and Allocations

Your contract specifies the number of crime lower matter starts (the number of new matters you can open per contract year). Exceeding your matter start allocation means the excess matters are funded at your own risk. Monitor your usage through CWA’s reporting functions and apply for additional matter starts before you run out.

Monthly Billing

Crime lower bills are typically submitted monthly. CWA produces a monthly schedule of all matters submitted for payment. Providers should reconcile this against their own records to ensure all matters have been captured and no matters have been inadvertently omitted.

Rejection Handling

CWA will reject submissions that fail automated validation checks. Common rejection reasons include: missing or invalid billing codes, matter type/offence category mismatches, outcome codes inconsistent with the matter type, and claims where the client’s eligibility cannot be verified. Rejected claims must be corrected and resubmitted; delays in doing so affect cash flow.

Audit Risk in Criminal Legal Aid

The LAA’s Contract Management team audits criminal providers periodically. The most common audit findings in criminal legal aid are:

Incomplete file notes (particularly for police station work where attendance records are thin)
Incorrect outcome codes (most commonly the conflation of NFA and released without charge categories)
Incorrectly claimed escape fee matters (where the actual time claimed is not supported by contemporaneous records)
Missing representation order documentation for magistrates’ court work

Maintaining a clean audit record requires consistent file management discipline. Every police station attendance should produce a contemporaneous file note of reasonable length and detail; every magistrates’ court representation should be supported by a representation order on file.

Technology and Automation in Criminal Billing

The volume and complexity of criminal legal aid billing — often involving dozens of police station matters per month across a team of duty solicitors — makes it an ideal candidate for workflow automation. AI-assisted billing tools can automatically log attendance, assign the correct billing codes, calculate whether an escape fee threshold is reached, and prepare the monthly CWA submission.

Obiter captures attendance and activity automatically, assigns the correct crime lower billing codes based on matter type and offence category, and alerts fee earners when an escape fee threshold may be within reach. For busy criminal defence teams, that means fewer missed uplifts, fewer coding errors, and substantially less end-of-month billing admin.
