Legal Aid Billing Rules Change for Prison Law Cases

Legal aid billing can sound like a niche update, but it reaches into something bigger: whether prison law work is clearly funded and whether firms know what they can claim. On 31 July 2026, the Legal Aid Agency said updates to the Criminal Bills Assessment Manual, known as CBAM, and its supervisor guidance took effect for the 2025 Standard Crime Contract. The contract covers criminal legal aid providers in England and Wales. (gov.uk) If you are new to this area, think of CBAM as the rulebook used to assess criminal legal aid bills outside the Crown Court. The manual says it guides how recorded costs are checked by LAA processing staff, contract managers and audit teams, so wording changes here can affect what providers are paid and how they prove their work.

The headline change is in prison law. The Legal Aid Agency says it made bespoke funding changes after discussions with the Association of Prison Lawyers, and that the Prison Law chapter now gives clearer, more practical guidance for providers and LAA caseworkers, including on Parole Board work and other core prison law issues. (gov.uk) That matters because prison law is not one small corner of the manual. In the July 2026 version, section 13 covers questions such as sentence calculation, close supervision and separation referrals, Category A reviews, disciplinary cases, Parole Board cases, judicial review and exceptional case funding. In other words, this is the part of the rulebook that helps decide how representation around custody and release is understood for legal aid purposes. (assets.publishing.service.gov.uk)

A second set of changes is about admin and billing across criminal legal aid, not just prison law. The LAA says the amendments are meant to reduce the administrative burden on providers, especially around payment for administrative activities such as form-filling and other contact with the agency, while also bringing criminal guidance closer to civil legal aid guidance for consistency. (gov.uk) Here is the plain-English version: not every minute spent in an office is payable legal work. The CBAM says purely administrative matters and office overheads are not recoverable, but work counts as fee-earning if it goes directly to providing legal services to the client. That distinction is dull on the surface, yet it is one of the most important lines in publicly funded law because it shapes what can be claimed and what has to be absorbed by the firm.

The updated manual also changes the general principles used to assess the cost of letters and telephone calls, and the LAA says this will have a wider effect across criminal legal aid cases. The agency adds that it has borrowed wording from civil guidance here as well, again to make the approach more consistent. (gov.uk) The current CBAM shows why this area matters. Routine letters and routine telephone calls are paid at a set routine rate, but assessors still have to decide whether each item was reasonable. The manual also says administrative calls with no legal content are overheads and cannot be claimed. **What this means:** firms will need clean attendance notes and clear billing records, because small items such as calls, messages and correspondence can still become points of dispute.

The supervision update sits alongside all of that billing detail. The Legal Aid Agency says its supervisor guidance has been refreshed to match changes made by the Solicitors Regulation Authority on 12 June 2026, after the Court of Appeal's 31 March 2026 decision in CILEX and others v Mazur and others. The SRA says its revised guidance was meant to help firms make sure their supervision arrangements were lawful. (gov.uk) The key idea is responsibility. The SRA says the Court of Appeal confirmed that an authorised lawyer keeps responsibility for delegated litigation tasks, and that solicitors must be satisfied they are exercising proper direction, management, supervision and control. The LAA's July 2026 supervisor document brings that approach into crime contract guidance and says supervisors must be accessible, remain responsible for work done under their supervision, and carry out file reviews that reflect each worker's experience. (rules.sra.org.uk)

For providers, this is not just a reading exercise. The LAA's own supervisor guidance says firms must submit accurate supervisor declaration forms for each person acting as a supervisor under the 2025 contract, and must notify the agency within 21 days of significant staffing changes that could affect contract work. External supervision is allowed only in limited cases when a supervisor is temporarily absent. (assets.publishing.service.gov.uk) **What this means:** if you run or work in a criminal legal aid practice, 31 July 2026 was the date to re-check three things at once: how prison law files are opened and billed, how everyday contact such as letters and calls is recorded, and how supervision is evidenced on paper. The LAA presents these changes as operational improvements, particularly for prison law. We can reasonably infer a wider point too: when the rulebook becomes clearer, firms spend less time arguing over claims and more time on clients, which matters in an area as fragile as access to justice.
