Locum work tends to get described in one of two ways. Either it’s freedom, the escape from rosters and practice politics into a career you actually control, or it’s instability, a stopgap for people between proper jobs who haven’t settled yet. Neither description is much use if you’re genuinely trying to decide, because both are caricatures built by people arguing a position rather than describing the work.
The reality sits somewhere less dramatic. Locum work offers real advantages that permanent posts struggle to match, and it asks you to accept trade-offs that some doctors barely notice and others find wearing within a year. Which camp you fall into depends less on the work itself than on your circumstances, your temperament, and what stage of your career you’re at. So rather than making a case either way, here’s an honest account of what you’d be taking on, so you can weigh it against your own situation.
What You Gain: Control Over Your Own Time
The central appeal is straightforward, and it’s the thing almost every locum mentions first. You decide when you work. Not in the theoretical sense of negotiating leave with a practice manager who has their own problems, but actually deciding, by taking a placement or declining one. If you want six weeks off in the middle of the year, you take six weeks off. Nobody has to approve it and nobody sighs about cover.
That control extends to where you work and what kind of work you do. You can try different settings, different regions, and different patient populations without committing your career to any of them, which is genuinely valuable if you’re still working out what suits you. Many doctors also find real relief in stepping away from the parts of permanent practice that have nothing to do with medicine, the meetings, the internal politics, the accumulated administrative load that grows around a long-held post. You arrive, you do clinical work, and you leave. For people who came into medicine to practise it rather than to manage a small business, that clarity can be restorative in a way that surprises them.
What You Give Up
The trade-offs are equally real and worth facing squarely. The obvious one is income security. Locum rates are often higher per day, which is what draws people in, but there’s no guarantee of continuous work, and the gaps between placements are unpaid. A month with nothing suitable is a month with no income, and that risk sits with you rather than an employer.
Everything a permanent post quietly provides becomes your responsibility too. Leave is unpaid because it’s simply time you didn’t work. Sick days are the same. Retirement contributions, professional development, and the various entitlements that accumulate in the background of a salaried role all become things you fund and organise yourself. Beyond the financial side, there’s the loss of continuity with patients, which matters more to some doctors than others but is a genuine change if you value long-term relationships and seeing outcomes over years. You also give up a settled team, the colleagues who know you and whose judgement you trust, and being the new person repeatedly has a social cost that’s easy to underestimate until you’ve lived it.
The Practicalities People Underestimate
Beyond the big trade-offs sit a set of practical realities that rarely feature in the freedom-versus-instability debate but occupy a surprising amount of a locum’s attention. Credentialling and registration paperwork is the main one, since each facility has its own requirements and processes, and keeping documentation current and accessible becomes an ongoing administrative task rather than a one-off.
Onboarding is the other constant. Every placement means a new set of systems, unfamiliar software, different local protocols, and working out who to ask about what. Experienced locums get quick at this, but it never disappears, and the first days of any placement carry a cognitive load that permanent staff don’t face. Then there’s the logistics of travel and accommodation for placements away from home, which can be arranged for you or left to you depending on how you work. Finally, managing your own finances takes real discipline, since irregular income requires planning around quiet periods and setting money aside for the obligations that would otherwise be handled by payroll. None of this is difficult, but it’s work, and it’s worth counting before you decide.
How the Work Actually Comes to You
One practical question people often have is simply how placements are found, because the mechanics aren’t obvious from the outside. Approaching facilities directly is possible and some doctors build relationships this way over time, particularly with places they’ve worked before, but it’s slow and it means you’re doing your own business development alongside clinical work.
Most doctors work through agencies instead, and the reason is largely administrative rather than about access to work. Alocum doctor recruitment agency handles the matching between your availability and facilities that need cover, carries much of the credentialling burden, and generally sorts out travel and accommodation arrangements for placements away from home. That removes a substantial chunk of the practical overhead described above, which is what makes locum work sustainable rather than exhausting for a lot of people. It also means someone else is looking for your next placement while you’re working your current one, which addresses the gap problem more effectively than anything you could manage yourself. Working out early how you want to source your work, and building a relationship with people who understand what you’re looking for, tends to shape the experience more than any other single decision.
Deciding Whether It Suits You
The honest test is to hold locum work against your own circumstances rather than against an ideal. Career stage matters a great deal. Doctors early on often find the variety valuable for working out what they want, while those later in their careers frequently use it to wind down on their own terms or to escape administrative burdens they’ve had enough of. The middle years, when mortgages and school fees are at their heaviest, are where income variability bites hardest.
Your financial position is the second test, since a buffer that covers a few months makes irregular income manageable and no buffer makes it stressful. Your temperament is the third, because some people find uncertainty energising and others find it quietly corrosive, and you probably already know which you are. If you’re genuinely unsure, the sensible move is to try it at the edges before committing, taking occasional placements alongside existing work to see how the reality lands. That gives you a real answer rather than a theoretical one, and it costs you very little to find out.
