Fee earner utilisation — the proportion of a solicitor’s working time that is billable — is the single most important operational metric in a law firm. A 5% improvement in utilisation across a ten-fee-earner firm can add tens of thousands of pounds to the bottom line without winning a single additional matter. Yet most firms either do not measure it accurately or, worse, set targets and then fail to understand why they are being missed.

The reality in most UK firms is that fee earners are working hard. The problem is not effort. The problem is that a large portion of their working day is consumed by activities that cannot be billed: chasing clients for information, reformatting documents, managing email, handling administrative queries, attending non-billable internal meetings, and reconstructing time records at the end of the week. This guide explains how to measure utilisation properly, set targets that are achievable and motivating, and — critically — remove the non-billable drag that prevents fee earners from hitting those targets.

What Is Fee Earner Utilisation and How Should You Measure It?

Utilisation is expressed as a percentage: billable hours divided by total available hours. But each of those terms needs to be defined carefully or the metric becomes meaningless.

Available hours: the denominator

Available hours should reflect genuinely workable time, not a theoretical maximum. A fee earner working a standard 37.5-hour week has approximately 1,750 available hours per year after accounting for 25 days of annual leave, bank holidays, and a realistic allowance for sick leave and training. Some firms use a higher denominator — 2,000 or even 2,200 hours — which makes utilisation figures look worse than they are and demoralises fee earners who are performing well.

The right approach is to agree on a denominator that reflects realistic availability and apply it consistently. If your firm expects 1,600 available hours per year from each fee earner, use that figure.

Billable hours: the numerator

Here is where many firms go wrong. Billable hours should mean hours that are actually billed to clients and collected, not hours recorded in the time recording system. The distinction matters because write-offs — billing less than recorded time — mean that a fee earner with 1,200 recorded hours might generate bills for only 1,050 of them.

Tracking both recorded utilisation and realisation rate separately gives you two different diagnostic signals. High recorded utilisation with low realisation points to a pricing or scoping problem. Low recorded utilisation with good realisation suggests either under-recording or a genuine capacity problem.

Industry benchmarks

The Law Society’s 2024 benchmarking data suggests that average chargeable hours for solicitors in private practice runs at around 1,100 to 1,300 hours per year, implying utilisation rates of 63–75% against a 1,750-hour denominator. High-performing commercial firms typically target 75–80%. Legal aid and publicly funded practices often run lower due to the nature of the work.

Setting a utilisation target significantly above industry norms without addressing the structural causes of non-billable time is a recipe for burnout and turnover, not profit.

Why Fee Earners Miss Utilisation Targets

Before setting targets, understand why the current position falls short. The most common causes are systematic and fixable.

Under-recording, not under-working

A significant portion of billable activity is never recorded. Fee earners who work in the morning before switching on the time recording system, take a client call while walking between meetings, or spend 20 minutes reviewing a document without opening a time entry — all of this is lost.

Research by legal practice management consultants consistently finds that fee earners under-record by 15–30 minutes per day on average. Over a working year, that is 60–120 hours of billable time that simply disappears. At a rate of £200 per hour, that is £12,000 to £24,000 per fee earner per year in unrecorded revenue.

Administrative time consumption

A 2023 study by the Legal Services Board found that solicitors in firms without dedicated support staff spend on average 2.5 hours per day on non-billable administrative tasks: drafting client care letters, formatting documents, managing diaries, handling routine email correspondence, and filing. In a 7.5-hour working day, that is a structural 33% reduction in available billable time before the fee earner has done any chargeable work.

Meeting culture

Internal meetings — team meetings, supervision sessions, business development updates, training sessions — are necessary but their frequency and duration are often poorly managed. A fee earner who attends four hours of internal meetings per week has effectively lost 200 hours per year to non-billable activity. Audit internal meeting time before concluding that fee earners simply are not working hard enough.

Unclear targets and poor feedback loops

Fee earners who do not receive regular feedback on their utilisation position cannot self-correct. A monthly report that arrives three weeks into the following month is too slow to drive behaviour change. Fee earners need to be able to see their position weekly — ideally in real time — to manage their own performance.

Setting Targets That Actually Work

Utilisation targets should be challenging enough to drive performance but achievable enough to remain credible. A target that everyone misses is worse than no target — it teaches people that the number is meaningless.

Differentiate by role and practice area

A managing partner who spends 30% of their time on business development and firm management cannot hit the same utilisation target as a fee earner whose role is purely client-facing. A solicitor in a legal aid family practice has different billing economics than a corporate lawyer on a commercial transaction. Segment targets accordingly.

A reasonable framework for a mid-sized UK firm might look like:

Newly qualified – 3 years PQE: 70–75% utilisation target, approximately 1,225–1,312 billable hours per year
3–7 years PQE: 75–80% target, approximately 1,312–1,400 hours
Senior associates/associates with supervisory duties: 70–75%, adjusted for supervision time
Partners with significant client development roles: 55–65%, reflecting BD time

Make targets visible and timely

Weekly utilisation dashboards — accessible to the fee earner and their supervising partner — are significantly more effective than monthly reports at changing behaviour. The goal is to give fee earners the information they need to make decisions during the week, not to provide a retrospective verdict three weeks later.

Connect targets to compensation meaningfully

If hitting utilisation targets has no material impact on a fee earner’s income, the target is aspirational rather than motivational. Lockstep compensation structures that ignore individual performance are particularly prone to this problem. Even a modest discretionary element tied to consistent target achievement sends a clear signal about what the firm values.

Reducing Non-Billable Drag: Practical Steps

The most sustainable way to improve utilisation is not to pressure fee earners to record more hours — it is to remove the non-billable work that is consuming their time.

Automate time recording

Passive time capture tools — software that monitors document activity, email, calls, and meetings and auto-populates time entries for review — consistently recover 30–60 minutes of recorded billable time per fee earner per day. The fee earner reviews and approves entries rather than reconstructing their day from memory, which is both faster and more accurate.

Delegate or automate administrative work

Administrative tasks that currently fall to fee earners should either be delegated to support staff or automated. Client onboarding documents, standard engagement letters, AML form chasing, diary management, and routine correspondence are all candidates for automation or delegation. Every hour of administrative work shifted away from a fee earner is an hour that can be either billed or spent on genuinely non-billable but valuable activity like client relationship management.

Redesign internal meeting structures

Audit all standing internal meetings. Ask whether each one requires fee earner attendance, whether it could be shorter, or whether it could be replaced by a written update. Many firms find they can reduce internal meeting time by 30–40% without losing information flow.

Fix the client communication bottleneck

A disproportionate amount of fee earner time is consumed responding to client queries that could be handled by a support member or resolved by better client communication systems. Clients who receive regular matter updates without needing to chase are less likely to generate reactive calls and emails that pull fee earners out of billable work.

Obiter directly attacks the utilisation problem by automating the administrative work that consumes fee earner time. Its AI reads client emails, drafts appropriate responses for approval, records the associated billable time automatically, and handles routine administrative tasks — AML checks, time narratives, billing preparation — without fee earner input. Firms that have deployed Obiter consistently report material improvements in both utilisation rates and fee earner satisfaction, because more of each working day is spent on the legal work that fee earners came into the profession to do.
