What is locum work? In its simplest form, locum work refers to temporary clinical staffing that fills gaps when regular staff are unavailable due to holidays, sickness, or vacancies. It is a well-established feature of the United Kingdom’s healthcare system, ensuring patients can access timely care even when permanent team members are not on site. This guide unpacks the concept, explores how locum roles operate, and offers practical advice for anyone considering a career as a locum or seeking to hire temporary clinical staff.
What Is Locum Work In Practice?
Locum work is about temporary coverage. A locum clinician — whether a doctor, nurse, pharmacist, dentist, or allied health professional — works for a fixed period, ranging from a few hours to several weeks. The arrangement is usually facilitated by an agency or platform, though some clinicians work directly with an employer on a temporary contract. The primary aim remains constant: to deliver safe, effective care when a resident team cannot meet demand.
Locum Work versus Permanent Roles
Understanding the distinction between locum work and permanent positions is crucial for anyone exploring this path. Locum roles offer flexibility, variety and often different shift patterns, but they typically come with limited continuity of care with a patient base. Permanent roles provide long-term employment, structured career progression, and a stable salary with government pension arrangements. In contrast, locum work is designed for short to medium-term placements, giving clinicians the chance to explore specialties, locations and work cultures.
The Mechanics: How Locum Arrangements Are Structured
Most locum work in the UK is facilitated through registered agencies or platform marketplaces. A clinician registers, confirms availability, and reviews shifts posted by NHS trusts, private practices or hospitals. Payscales may be set by the agency, contract terms by the employer, and taxes by HM Revenue & Customs. Two common models exist:
- Agency and PAYE: The locum works through an agency that handles payroll, taxes, and limited benefits. The clinician is typically paid via PAYE (Pay As You Earn) with deductions for tax and National Insurance.
- Umbrella or Limited Company: Some clinicians operate via an umbrella company or their own limited company, which can offer different tax reliefs and allowances. This model often requires more administration but can yield certain financial advantages.
The Advantages of Locum Work
There are many reasons why medical and healthcare professionals choose locum work. The flexibility to tailor your schedule, the breadth of clinical exposure, and the opportunity to travel or work in rural and urban settings are among the most common draws. For some, locum roles are a route back to practice after a career break, or a way to test different specialties before committing to a formal specialty training path.
Flexibility and Control
Locum work offers the ability to select shifts that fit around personal commitments, family time, or study. Clinicians can plan weeks off between blocks of shifts, choose part-time hours, or pursue a portfolio career that balances clinical duties with research or education.
Variety and Experience
Each assignment can present new clinical challenges, team dynamics and patient populations. This variety can be stimulating and help enhance clinical decision-making, communication skills, and adaptability — valuable assets in any medical career.
Earnings and Financial Considerations
Locum rates can be competitive, particularly for urgent or high-demand periods. However, financial planning is important, since shifts may not offer guaranteed hours, holiday pay, or sick leave in the same way as permanent roles. Clinicians often factor in travel costs, accommodation, and the potential benefits they are foregoing by not being permanently employed.
Who Can Work as a Locum? Sectors and Roles
Doctors and General Practitioners
GPs and hospital doctors are among the most common locum professionals. GP locums fill holiday periods, sickness cover, and surge capacity during peak times. Hospital doctors may work on short-term cover in A&E, medicine, surgery, or radiology departments. The pathway typically involves registration with the General Medical Council (GMC), employment through an agency or hospital, and compliance with NHS safeguarding and continuing professional development (CPD) requirements.
Nurses and Midwives
Nursing locums are a core part of NHS resilience. Community, district, and hospital nurses, as well as midwives, can take on temporary shifts to cover peak periods, maternity leaves, or staffing shortfalls. Requirements include appropriate professional registration (NMC in the UK), evidence of recent practice, and appropriate safeguarding clearances.
Dentists and Pharmacists
Locum dentists provide temporary coverage in private and NHS dental practices, while locum pharmacists may step into hospital and community settings to maintain service levels. Both roles demand robust professional registration with the General Dental Council (GDC) or General Pharmaceutical Council (GPhC) and adherence to professional indemnity standards.
Allied Health Professionals
Locum opportunities extend to physiotherapists, occupational therapists, speech and language therapists, radiographers and other allied health professionals. These posts help ensure continuity of rehabilitation and diagnostic services when permanent staff are unavailable.
Starting a Career as a Locum: Step-by-Step
Qualifications, Registration and Compliance
Before embarking on locum work, confirm you meet the professional registration requirements for your discipline. This includes current registration with the relevant regulatory body (for example, GMC for doctors, NMC for nurses, GDC for dentists). You will also need up-to-date DBS (Disclosure and Barring Service) checks, vaccination records as required, and evidence of continuing professional development. Compliance with safeguarding policies and local practice requirements is essential.
Choosing the Right Agency or Platform
Choosing a reputable agency or platform is critical. Look for those with robust safeguarding practices, transparent billing, and clear terms regarding pay rates, holiday entitlements, and assignment lengths. Ask about support services, such as credential verification, reasonable travel allowances, and access to indemnity coverage.
Setting Your Terms and Rates
Before accepting shifts, determine your preferred rates, availability, notice periods, and any minimum assignment lengths. Some clinicians negotiate higher rates for unsociable hours or high-demand locations. Keep a record of your total earnings, deductions, and any expenses to assist with tax planning.
Compliance, Safeguarding and Induction
Most locum roles require a brief induction at the start of an assignment. Read all local guidelines, practice policies and patient safety protocols. Ensure you have the required training on resuscitation, infection control and GDPR data-handling. Induction helps you integrate with the team quickly and deliver safe patient care from day one.
Finding Locum Work: Platforms, Agencies and Networks
Strategies to Locate Shifts
To secure locum positions, utilise a blend of platforms, agencies and professional networks. Some clinicians prefer a handful of trusted agencies, while others diversify across several platforms to maximise opportunities. Networking with colleagues, attending local healthcare events, and joining professional forums can uncover unadvertised shifts.
Creating a Standout Locum CV
Your CV should clearly outline your professional registration, areas of clinical competence, recent placements, and CPD. Include API-friendly details like current DBS status, indemnity coverage, and access to equipment and scope of practice. A short professional summary highlighting your adaptability, reliability and clinical strengths can help you stand out.
Networking and Referrals
Word-of-mouth remains powerful in locum recruitment. Maintain positive relationships with hosts and agencies, request feedback after assignments, and ask for referrals. Satisfied clients often recommend locums who demonstrate punctuality, teamwork and clinical excellence.
Finance and Legalities in Locum Work
Tax, National Insurance and Payroll
Locums may be paid through PAYE, an umbrella company, or via their own limited company. Each route has tax implications and administrative considerations. It is wise to consult a tax adviser familiar with healthcare workers’ arrangements to optimise take-home pay while staying compliant with HMRC rules.
Holiday Pay, Sickness and Benefits
Unlike permanent NHS staff, locums may not receive the same holiday entitlement automatically. Some assignments include holiday pay, while others are paid as standard rates with holiday adjustments. Understand how a specific shift handles annual leave, sick pay and pension contributions, particularly if you work through an umbrella or agency.
Indemnity and Liability
Professional indemnity is essential for all clinicians. Confirm that your indemnity covers locum work and consider whether your existing policy extends to temporary placements. If unsure, seek advice from your regulator or a medical indemnity provider to avoid gaps in cover.
Practical Considerations for Locum Assignments
Rural versus Urban Placements
Rural shifts can offer unique clinical experiences, broader scope of practice and shorter commutes, but may require relocation or long travel times. Urban settings often provide access to larger teams, more resources, and a faster pace. Weigh travel, accommodation, and professional support when choosing assignments.
Shift Patterns and Work-Life Balance
Shifts can span early mornings, late evenings, weekends and on-call periods. Flexible schedules may support study or family commitments, but irregular hours can impact rest and wellbeing. Plan carefully to maintain a sustainable balance.
Patient Continuity and Team Dynamics
Locums contribute to continuity of care but may encounter differences in electronic health records, local protocols, or team culture. Proactive communication, thorough handovers, and a respectful approach help foster effective teamwork and patient safety.
The Future of Locum Work
Technology and Platforms
Digital platforms continue to streamline locum recruitment, credentialing and payroll. Advanced matching algorithms pair clinicians with shifts that fit their skills and availability, while secure telemedicine and hybrid roles open new avenues for temporary clinical work.
Policy and Workforce Planning
As healthcare systems adapt to demographic shifts and rising demand, locum capacity remains a critical component of workforce planning. Flexible staffing models help reduce waiting times and maintain service resilience, particularly during public health crises or seasonal peaks.
