Ever wondered how pharmacies keep their doors open when their regular pharmacist is on holiday, unwell, or on training? The answer often lies with a crucial and dynamic professional: the locum pharmacist.
If you're a newly qualified pharmacist, or perhaps you're years into your career and craving a change, the world of locuming can seem both intriguing and daunting. It promises flexibility, variety, and often, a higher rate of pay. But what does it actually involve, and how do you get started?
Consider this your complete beginner's guide to becoming a locum pharmacist in the UK.
What Exactly is a Locum Pharmacist?
Think of a locum pharmacist as the pharmacy equivalent of a supply teacher. The term 'locum,' derived from the Latin phrase locum tenens, means 'place holder.' In essence, a locum is a self-employed pharmacist who steps in to cover temporary gaps in a pharmacy's rota.
This could be for a single day, a week, or even for several months to cover maternity leave or a long-term absence. They perform all the duties of a regular pharmacist, from clinical checks and dispensing prescriptions to providing patient consultations and managing the pharmacy team. They are the versatile professionals who ensure that patient care and pharmacy services continue without interruption.
Why Choose to Be a Locum Pharmacist? The Perks of the Job
The locum lifestyle attracts pharmacists for many reasons. Here are some of the biggest draws:
Unbeatable Flexibility: This is the number one reason many pharmacists choose to locum. You are your own boss. You decide when you work, where you work, and for how long. This freedom allows for a much healthier work-life balance, giving you time for family, travel, or other pursuits.
Diverse Experience: Working in various pharmacies—from quiet village independents to bustling city multiples and even GP surgeries—exposes you to different systems, patient demographics, and working cultures. This rapidly broadens your clinical and professional experience in a way a static role cannot.
Higher Earning Potential: Locum pharmacists are typically paid a higher hourly rate than their permanently employed counterparts. This is to compensate for the lack of benefits like sick pay, holiday pay, and employer pension contributions. With good financial planning, locuming can be very lucrative.
Networking Opportunities: Each new pharmacy is a chance to meet new colleagues, from technicians and dispensers to area managers and pharmacy owners. Building a strong professional network can open doors to future opportunities you might not have otherwise found.
The Essential Checklist: How to Become a Locum Pharmacist in the UK
Ready to take the plunge? Here’s a step-by-step guide to getting started.
1. Get Qualified and Registered
This is the foundation. You must have completed your Master of Pharmacy (MPharm) degree, finished your pre-registration training year, and be successfully registered with the General Pharmaceutical Council (GPhC).
2. Gain Solid Experience
While you can technically locum as soon as you qualify, most experts and agencies recommend gaining at least 1-2 years of post-registration experience. This builds your confidence, speed, and ability to adapt quickly to new environments – all essential skills for a successful locum.
3. Set Up Your Business
As a locum, you are self-employed. This means you need to:
Register with HMRC: You'll need to decide whether to operate as a sole trader (the simplest option) or a limited company.
Get an Accountant: It's highly advisable to hire an accountant who specialises in locums or contractors. They will be invaluable for managing your tax returns, expenses, and understanding regulations like IR35.
Open a Business Bank Account: Keep your personal and business finances separate from day one.
4. Arrange Your Documents
You’ll need a portfolio of professional documents ready to go. Most agencies and employers will ask for:
GPhC Registration Number
Professional Indemnity Insurance Certificate
DBS Check (Disclosure and Barring Service)
Proof of Right to Work in the UK (e.g., passport)
A Professional CV
Proof of Immunisations (e.g., for flu jabs)
Smartcard Number
5. Find Work
There are three main ways to find locum shifts:
Locum Agencies: The most common route for beginners. Agencies have relationships with numerous pharmacies and will find and book shifts for you in exchange for a commission (usually paid by the pharmacy).
Booking Apps: A growing number of platforms now allow you to browse and book shifts directly from your phone, giving you more control over rates and locations.
Direct Networking: Once you build a reputation, pharmacies may start contacting you directly. This often leads to better rates as there's no agency fee involved.
The Challenges of Locuming: A Balanced View
The locum life isn't without its challenges. It’s important to be aware of the downsides:
No Employment Benefits: You don't get sick pay, paid holidays, or an employer pension contribution. You must budget for these yourself.
Instability: Work can sometimes be inconsistent, especially in certain regions or times of the year.
Constant Adaptation: Every day can be a 'first day.' You need to be able to quickly learn new computer systems (SOPs) and get along with a new team.
Financial Discipline: You are responsible for managing your own taxes, national insurance, and pension contributions. Forgetting to set money aside for your tax bill can be a costly mistake.
A Rewarding Career Path
Becoming a locum pharmacist is a fantastic career choice for those who value autonomy, variety, and a dynamic work environment. It places you in the driver's seat of your career, allowing you to shape a professional life that truly fits your personal one.
By being organised, proactive, and committed to excellent patient care, you can build a successful and fulfilling career as a locum pharmacist, becoming an indispensable asset to the UK's healthcare community.
