How to Manage Your Locum Diary Effectively and Maximise Your Income

One of the most significant adjustments when moving to locum practice is the shift from a predictable monthly salary to a variable income driven entirely by the sessions you book, the rates you negotiate, and how efficiently you manage your availability. Most experienced locum GPs develop their diary management systems gradually — through trial, error, and lessons learned the hard way. This guide compresses that experience into a practical framework you can apply from your first month of locum work.

The Foundation: Build Around Anchor Sessions

The most stable locum diaries are not built on ad hoc bookings — they are built on anchor sessions: regular, recurring commitments at two or three practices where you work weekly or fortnightly on a consistent basis. Anchor sessions provide predictable income, reduced cognitive load (you know the systems, staff, and patients), and the professional continuity that supports your revalidation and appraisal requirements.

Practices value anchor locums highly. When their regular GP is away, you are the first call. When they are covering unexpected absence, your availability is assumed. This relationship also tends to attract better rates over time — practices pay more to retain clinicians they trust than to take a chance on someone new at short notice.

The best way to build anchor relationships is simple: do consistently excellent clinical work, communicate clearly with the practice manager, make yourself easy to rebook, and give plenty of notice when you are unavailable. Practices are not looking for perfection — they are looking for reliability.

Set Your Minimum Rate and Hold It

One of the most common and costly mistakes new locum GPs make is accepting below-market rates from practices that test the price of supply. Setting a clear minimum rate and communicating it confidently from the outset saves significant frustration and builds appropriate professional standing.

In 2025, the established market range for locum GP sessions in England is:

Do not discount your rate for regular bookings — it signals that your advertised rate was inflated in the first place, and it sets a precedent that is difficult to reverse. Instead, offer additional value for regular bookings through reliability, flexibility, and easy communication.

Use Multiple Booking Channels

Relying on a single channel for all your session bookings creates fragility in your diary. The most resilient locum GPs combine:

• Specialist agency relationships — SHR Group and other primary care recruitment agencies maintain active relationships with large numbers of practices and can fill diary gaps quickly, particularly at short notice. This is the fastest route to building a full diary when starting out.
• Direct practice relationships — built over time through consistent, high-quality clinical work. The most reliable and often best-paid route once established, as there is no agency margin.
• NHS staff banks — most ICBs and NHS organisations maintain staff banks for locum GPs. Rates may be below market but the volume of opportunity is high and the process is straightforward.
• GP chambers — local GP chambers often have a pool of work available to members and provide administrative support that reduces your overhead.

Block Your Availability Strategically

Managing your availability is as important as booking sessions. If you are available every day, you will be reactive rather than strategic — filling gaps rather than choosing the best sessions. A more effective approach:

• Block non-work days at the start of each month and treat them as fixed commitments before any sessions are booked. Protecting rest and personal time is not laziness — it is sustainability planning.
• Build in CPD, appraisal, and admin time as protected diary blocks. These are professional commitments, not optional extras. A locum GP who neglects CPD to maximise sessions is building towards a revalidation problem.
• Plan holidays far in advance and notify your anchor practices as early as possible. Practices that value you will plan around your availability — and they appreciate the notice.

Last-Minute Requests: When to Say Yes and What to Charge

Last-minute session requests are a permanent feature of locum life. Whether to accept them is a judgement call based on your current workload, the rate offered, and the clinical demands you would be walking into. Key principles:

• A premium for genuine short-notice cover is entirely reasonable and widely expected. Practices requesting emergency cover on the day or next day anticipate paying a premium — if they do not offer it, ask for it directly and without embarrassment.
• You are entitled to know what you are walking into. Before accepting a last-minute session, find out the clinical demand (how many patients, what type of list), whether the clinical system is SystmOne, EMIS, or Vision, and whether there is an on-site clinical lead available for support.
• Saying no to last-minute sessions you genuinely cannot manage is a legitimate professional decision. Overcommitting and delivering suboptimal care is worse for you, the practice, and patients than simply declining.

Managing Income Variability

Seasonal variation in locum demand — busy autumn, quieter January, surge in April — is entirely predictable once you have experienced it. Managing the financial impact is straightforward with two disciplines: maintaining a cash reserve equivalent to at least two months of typical gross income, and booking sessions further ahead than you think necessary during busy periods to avoid the crunch when demand drops.

Some locum GPs diversify their income during quieter periods through medico-legal work, GPwER (GP with Extended Roles) sessions, educational or training roles, or private practice. Building these income streams gradually provides useful diversification without the pressure of suddenly needing to replace clinical income at short notice.
