How to Become a Locum Pharmacist in the UK

Locum work means covering shifts at different pharmacies rather than working permanently at one — more control over when and where you work, at the cost of doing your own admin: tax, insurance, mileage, and finding the shifts in the first place. Here's what actually has to be in place before your first day, and the decisions worth making early.

You need to be registered with the General Pharmaceutical Council to practise as a pharmacist in Great Britain at all — this isn't locum-specific, it's the baseline for the profession. That means an accredited MPharm degree, a foundation training year, and passing the GPhC registration assessment. If you're already registered and practising, this part is done; locum work doesn't require anything further from GPhC beyond keeping your registration and CPD up to date, same as any other registered pharmacist.

You need your own indemnity cover for locum work — don't assume a pharmacy's own insurance covers you as a locum, in most cases it doesn't. Organisations like the Pharmacists' Defence Association (PDA) offer indemnity insurance aimed specifically at locums, and it's also sometimes included if you locum through certain agencies — check exactly what's covered before assuming you're protected.

• Independent/self-employed. You find your own shifts, invoice pharmacies directly, and handle your own tax via Self Assessment. More admin, but no agency fee taken out of your rate and full control over which shifts you take.
• Through an agency.The agency finds shifts and either pays you as a self-employed contractor or via PAYE/umbrella. Less admin and less searching for work, at the cost of a cut of the rate and less control over which shifts you're offered.
• Both. Plenty of locums do agency work for steady baseline income and pick up independent shifts on top for pharmacies or areas they already know.

See our guide on self-employed vs PAYE/umbrella for how the pay side of each actually works.

Word of mouth, pharmacy chains' own locum pools, agency listings, and locum-specific Facebook groups are all common routes in. Whichever you use, the same questions matter every time: is the rate fair for the area and workload, what's the PMR system, and is mileage or a break paid — see our guide on judging whether a rate is fair for how to work that out quickly from a shift offer.
