The short answer
The billable hour is under pressure because AI collapses the time taken by the work that historically justified it. Anthropic’s general counsel Jeff Bleich told the American Bar Association’s White Collar Crime Institute in March 2026 that he does not regard the billable hour as the solution, and the in-house counsel on the same panel agreed with him. In England and Wales the pressure is regulatory as well as commercial: the SRA Transparency Rules require price publication for certain services, fixed recoverable costs cap what litigants recover, and consumer research shows fixed fees gaining ground for years.
Why this matters now
Three pressures have converged. AI compresses the tasks that filled timesheets. Fixed recoverable costs, extended in October 2023, cap recovery in most claims up to £100,000 regardless of hours recorded. And the clients buying legal services are now saying publicly that time-based billing misaligns incentives.
Key facts
- 12 March 2026: Anthropic’s GC and in-house counsel from IBM and Liberty Mutual question time-based billing at the ABA White Collar Crime Institute, San Diego
- Six-minute increments: the unit the model depends on, and the unit AI compresses fastest
- SRA Transparency Rules: price publication required for certain services offered to individuals
- October 2023: fixed recoverable costs extended to most claims up to £100,000
- The catch: firm profitability still depends on leverage, which volume work supplies
What Anthropic’s general counsel actually said
Jeff Bleich, general counsel at Anthropic, spoke on a panel at the American Bar Association’s White Collar Crime Institute in San Diego on 12 March 2026, alongside senior in-house lawyers from Google, IBM and Liberty Mutual.
His central line was direct: “I don’t think the billable hour is the solution, and we’ve known it for a long time.” His argument was that AI is removing precisely the repetitive, high-volume work firms have historically been able to bill heavily for, and that this was never the work clients valued lawyers for in the first place.
He also described the model as having created a wedge between firms and clients, because clients want problems solved efficiently while the economics of time-based billing reward complexity and duration.
What makes the panel more interesting than a single speech is that the buyers agreed. Damon Hart, the top lawyer at Liberty Mutual, made the point that value now lies in strategy and results rather than in time put in. IBM’s general counsel Anne Robinson said she was open to firms approaching her to design alternative arrangements.
A footnote worth enjoying
Anthropic is represented in separate litigation by WilmerHale, the firm whose earlier incarnation, Hale and Dorr, is widely credited with inventing the billable hour under Reginald Heber Smith in the early twentieth century.
Why does AI break the model specifically?
Because the billable hour prices input, and AI collapses input while leaving output unchanged.
Document review, first-pass legal research, contract analysis and due diligence share three features: they are high volume, they are checkable against an external source, and they have historically taken a great many junior hours. Those are exactly the characteristics that make a task amenable to automation, and exactly the tasks that filled timesheets.
When a task that took forty hours takes four, the firm faces a choice it cannot avoid. Bill four hours and lose ninety per cent of the revenue. Bill forty and misrepresent the work. Or price the matter rather than the time.
That is the whole argument, and it does not depend on any prediction about how capable AI becomes. It only requires that clients know roughly what the tools can do, which they increasingly do.
What is different about the UK position?
The commercial pressure arrives alongside regulatory pressure that has been building independently, which is not true in the US.
Price transparency is a rule, not a preference
The SRA Transparency Rules require firms publishing an offering of certain services to individuals, including residential conveyancing, to publish price information prominently on their websites. The SRA has taken enforcement action against firms that fail to comply. A profession already required to publish prices is in a different position from one being asked to consider it.
Fixed recoverable costs cap recovery regardless of hours
Since October 2023 most claims up to £100,000 fall within a fixed costs regime, with an intermediate track assigning cases to complexity bands. In those cases the hours recorded are largely irrelevant to what the winning party recovers, and the gap between recorded and recoverable falls on the client. Our guide to the Civil Procedure Rules sets out the structure.
Consumers are already buying differently
The Legal Services Consumer Panel’s tracker survey has recorded fixed fee use rising substantially over the life of the survey, and unbundled services, where a client instructs a lawyer for defined parts of a matter only, reached their highest recorded level in the most recent tracker. Consumers are not waiting for firms to redesign pricing. They are buying less of it.
In practice
The regulatory and consumer trends point the same way as the AI argument, which is why the UK conversation is further along than the headline speech suggests. A firm treating this as an American debate has misread its own market.
What are the alternatives to the billable hour?
Five models, each transferring a different amount of risk from client to firm.
| Model | How it works | Who carries the risk |
|---|---|---|
| Fixed fee | Agreed price for defined scope | The firm, if the matter runs long |
| Capped fee | Hourly billing to an agreed ceiling | Shared, with the firm exposed above the cap |
| Subscription or retainer | Recurring fee for ongoing access | The firm, if demand exceeds expectation |
| Outcome or value-based | Price tied to result or value delivered | The firm, most heavily |
| Unbundled | Client instructs for defined tasks only | The client, for everything outside scope |
Each requires something the billable hour does not: knowing what a matter actually costs the firm to run. A firm that has only ever measured hours recorded does not have that information, and cannot price a fixed fee safely until it does.
Common mistake
A fixed fee without a clearly defined scope in writing, and a stated position on what triggers a variation, is a route to either a fee dispute or an unpaid overrun. Unbundling raises the same question more sharply, because the boundary of the retainer is also the boundary of the firm’s duty.
The problem nobody wants to discuss
Alternative pricing solves the client’s objection. It does not solve the firm’s economics.
The traditional firm model depends on leverage: partner time sold at a high rate, with profitability coming from associates and trainees billing volume work above their cost. Automate the volume work and the pyramid narrows. Move to fixed fees and the efficiency gain passes to the client by design.
That leaves firms needing a different answer to where profit comes from, and the honest answers are uncomfortable: fewer juniors, higher-value work only, or genuinely productised services delivered at scale. The first creates a supply problem in five years, since the mid-level lawyers of 2031 are the trainees recruited now. We look at what this means for entrants in our guide to whether AI will replace lawyers.
Performance measurement is the other casualty. If hours stop being the currency, appraisal, progression and bonus structures built on the timesheet need rebuilding, and most firms have a decade of infrastructure assuming otherwise.
The regulatory angle firms overlook
Pricing changes engage professional obligations, and a firm moving away from hourly billing is changing a term clients rely on.
Costs information must be accurate and not misleading, and the duty to keep clients properly informed about costs does not soften because the arrangement is now fixed. If anything the opposite: a fixed fee makes scope the contested territory, so the client needs to understand clearly what falls outside it and what happens if it does.
There is also a transparency question specific to AI. Where a client has agreed an hourly rate on the assumption of human effort and the work is substantially machine-assisted, the fairness of the charge is a live issue whether or not any rule currently compels disclosure. Institutional clients are increasingly addressing AI use in outside counsel guidelines, which converts it into a contractual obligation. The publicity constraints on how firms present pricing are covered in our guide to law firm marketing and the SRA rules.
What to work out before changing your pricing
- What your common matter types actually cost the firm to run, not what was recorded against them
- Which of your claim types now fall inside fixed recoverable costs, and the size of the recovery gap
- Whether your website pricing meets the Transparency Rules for every service you currently offer
- What your scope definitions say, and what triggers a variation
- How you would measure and reward performance if hours stopped being the currency
- What your panel terms and outside counsel guidelines say about AI use
Frequently asked questions
Is the billable hour ending?
Not immediately, but its dominance is under pressure from three directions at once: AI compressing the work that justified it, regulatory requirements on price transparency and fixed recoverable costs, and clients buying fixed fee and unbundled services in growing numbers.
What did Anthropic’s general counsel say about the billable hour?
Speaking at the ABA White Collar Crime Institute in San Diego on 12 March 2026, Jeff Bleich said he does not think the billable hour is the solution and that the profession has known this for some time, arguing that AI removes the repetitive work the model depended on.
What are the alternatives to hourly billing?
Fixed fees, capped fees, subscription or retainer arrangements, outcome and value-based pricing, and unbundled services. Each transfers risk differently, and all require the firm to know what a matter costs to run rather than only what was recorded against it.
Do UK firms have to publish their prices?
Firms publishing an offering of certain services to individuals, including residential conveyancing, must publish price information prominently on their websites under the SRA Transparency Rules. The SRA has taken enforcement action against firms that do not comply.
Should firms tell clients when AI has been used?
There is no general regulatory requirement to disclose it, but institutional clients increasingly address AI use in outside counsel guidelines, making it a contractual question. Where hourly billing assumes human effort and the work is substantially machine-assisted, the transparency issue arises regardless.
Why is moving to fixed fees difficult for firms?
Because profitability depends on leverage. Automating volume work narrows the pyramid, and fixed pricing passes the efficiency gain to the client by design, so firms need a different answer to where profit comes from and a different way to measure performance once hours stop being the currency.
The key points
- The buyers are saying it too: in-house counsel from IBM and Liberty Mutual agreed with Anthropic’s GC on the same panel
- The UK is further along: Transparency Rules and fixed recoverable costs were already moving pricing before AI arrived
- Pricing is the easy part: costing a matter accurately is what most firms cannot yet do
- Scope is where fixed fees fail: an undefined scope turns a price into a gamble
- Leverage is the unsolved problem: automating volume work narrows the pyramid that funds the firm
The practical takeaway
The interesting development is not that an AI company’s lawyer criticised the billable hour. It is that the general counsel buying legal services agreed with him on the same panel, and that in England and Wales the regulatory framework has been moving in the same direction independently of AI.
The firms that handle this well will do two unglamorous things first: work out what their matters actually cost to run, and write scope definitions tight enough that a fixed fee is a price rather than a gamble.
