If two doctors work the same shift, in the same hospital, on the same weekend, why does one arrangement cost so much more?
That's the question people dodge. Instead, they reach for lazy slogans. "Agencies are a rip-off." "Direct is always cheaper." "Cut out the middleman and everybody wins." Nice story. Usually wrong.
Here's what's actually happening. A direct locum arrangement means the doctor contracts straight with the hospital, practice, or service. No broker in the middle. An agency locum arrangement means a recruiter or staffing company sources the clinician, manages the placement, and bills the employer. Same doctoring. Different infrastructure.
And that infrastructure isn't free. Ever.
The central myth in this whole debate is that agency money somehow vanishes into a black hole of greed, while direct booking is pure efficiency. Nonsense. Money doesn't disappear. It gets redistributed. Into commission, yes, but also into recruitment labor, compliance checking, payroll, emergency replacement cover, invoice chasing, procurement processes, cancellation risk, and the plain old value of speed.
That's the real argument. Not morality. Not ideology. Who is doing the work. Who is carrying the risk. Who gets paid for friction.
This article is for people who want the grown-up version. Because the financially smarter route depends on who absorbs recruitment admin, governance burden, downtime, late changes, and the cost of a rota gap that needs filling now, not next Thursday.

What are you actually paying for when you book a locum?
Most people compare locum models the wrong way. They stare at the hourly rate like it's the whole story. It isn't. The rate is just the shiny number on the front of the box. The actual cost sits underneath: admin, reliability, speed, replacement capacity, payment systems, and the cost of things going wrong.
In a direct model, the organization pays the clinician more directly, but someone still has to source the doctor, verify documents, process approval, sort timesheets, answer rota emails at 9:47 pm, and deal with the "actually I can't do Sunday anymore" message. If that work lands on an internal staffing team, a consultant, or the doctor themselves, it still costs money. It's just less visible.
In an agency model, those jobs are outsourced. That margin everyone loves to sneer at? It often pays for exactly those hidden tasks. Sometimes badly. Sometimes very well. But pretending it's all deadweight is amateur economics.
I've seen departments boast that they "saved money" going direct, then quietly burn hours of consultant and manager time patching the rota, chasing pre-employment documents, and scrambling for backup when a shift falls apart. That isn't free. It's just not on the same invoice.
The money trail: where each pound actually goes
Let's strip this down.
An employer paying for a locum shift usually isn't just paying for clinical labor. They're paying for the shift to exist reliably. That means the doctor's compensation, payroll processing, onboarding, compliance checks, time approval, and some buffer against disruption. If an agency is involved, there's also the agency margin. But margin is not the same thing as profit. That's the first myth to kill.
A functioning locum agency typically covers candidate sourcing, reference collection, right-to-work checks, credentialing, database management, out-of-hours calls, payroll administration, timesheet reconciliation, invoice handling, and sometimes bad debt risk if the client pays late. Good agencies also benchmark rates across nearby hospitals, push departments to move faster, and find replacement cover when somebody drops out. That's real work. Messy work. Work that hospitals often don't want to do at scale.
Now the uncomfortable bit for direct-booking purists: cutting out the agency does not mean the employer "saves the middle." It means the middle gets rebuilt somewhere else. Internal rota coordinators spend time contacting clinicians. Medical staffing teams process paperwork. Procurement rules slow things down. Consultants message old locum WhatsApp groups because the official system is too clunky. And if the direct doctor cancels late, the service may need to pay even more for urgent rescue cover.
For doctors, the money trail can look just as leaky. A direct rate may be higher on paper, but then the invoice gets approved two weeks late because the supervising consultant was on annual leave. Or payroll puts you on a structure with deductions you hadn't properly calculated. Or your travel reimbursement "should be fine" until it mysteriously isn't. Or you spend your evening chasing signed timesheets instead of doing literally anything else.
And yes, agency work has its own leaks. Umbrella arrangements can eat away at earnings. Rate opacity is common. Some recruiters compress your pay while claiming the client "won't move," even when the market says otherwise. Travel and accommodation support varies wildly. Cancellation terms can be laughably one-sided.
This is why two identical shifts can produce completely different outcomes. In a scarce specialty with urgent demand, an agency may still get a doctor a strong rate because speed is valuable. In a stable local department with repeat cover needs, direct work may produce a better long-run deal for both sides. Volume matters. Geography matters. Specialty scarcity matters. Negotiating leverage matters.
Not sexy. Just true.
Direct locums: higher rates on paper, but not always more money in reality
Here's the myth: direct booking always means the doctor earns more. No. Sometimes the doctor earns more. Sometimes they just do more unpaid work for the privilege.
The direct model has real advantages. Fewer middlemen. Better relationship with the department. More chance of repeat work. Often more honest conversations about the rota and local pressures. If you're good, dependable, and known to the team, you can build something close to a preferred-supplier relationship without the formal nonsense. That can be lucrative. It can also be more pleasant. You stop being an interchangeable slot-filler and become "the person we call first."
That matters.
You may also get more room to negotiate rate, start times, block bookings, accommodation, and cancellation terms. And you get cleaner visibility into demand. If a department is desperate every second weekend, you'll see it. You can price that reality properly.
But direct work asks more of you. You have to source shifts. Maintain relationships. Handle contract details. Keep your compliance documents ready. Invoice properly. Chase payments. Clarify indemnity arrangements. Notice when a "recurring need" is actually a chaotic department making promises it never keeps. Agencies are often blamed for friction, but direct work can be friction with no support staff.
And there's a bigger issue people routinely ignore: opportunity cost. If your direct rate is higher but you spend hours hunting shifts, emailing medical staffing, and sitting through unpaid downtime between bookings, your effective earnings may be worse than an agency pipeline that keeps you consistently busy.
I've seen doctors proudly quote a better direct hourly rate while quietly working fewer total paid hours a month. That's not winning. That's rate vanity.
Direct arrangements tend to work best for clinicians who are well-networked, local, organized, and comfortable running their own mini-business. Also for niche specialists who are hard to replace and in stable departments that actually honor what they agree. If that's you, direct can be excellent. If it isn't, direct can turn into a spreadsheet hobby masquerading as freedom.
Agency locums: expensive middleman or paid problem-solver?
The reflexive hatred of agencies is overdone. Some recruiters deserve it. Plenty don't.
A good agency solves expensive problems fast. That's why it exists.
For doctors, agencies can open doors you simply wouldn't access alone, especially across multiple trusts, health systems, or regions. They can place you quickly, benchmark rates across sites, help with travel or accommodation, process payroll, and step in when a department starts playing games over timesheets or cancellations. That matters more than people admit. It's nice to say you want "direct relationships." It's less nice when you're personally arguing with three different admin offices over one missing approval email.
For employers, agencies provide candidate flow, compliance screening, backup options, and a single contact point when the rota is melting down. At 6 pm on a Friday, during a sickness crisis, nobody cares about staffing ideology. They care about whether an appropriately credentialed doctor can show up.
Now, the downsides. They're real. Margins can be opaque. Recruiter quality varies from excellent to embarrassing. Some use pressure tactics. Some play exclusivity games. Some promise "best rate" while quietly shaving your pay. And agencies can create distance between doctor and department, which weakens continuity and trust over time.
But the idea that agencies add no value is fantasy. In urgent vacancies, hard-to-fill geographies, short-notice sickness cover, or overstretched internal staffing teams, agency involvement is often economically rational. Expensive? Maybe. Irrational? No.
The mistake is treating all agency cost as waste. Often it's the price of responsiveness. Hospitals pay for speed all the time. Locum staffing is no different.
So which route wins? It depends on leverage, specialty, and friction costs
There isn't one winner. That's the final myth, and it needs to die.
The best financial choice is the one that gives you the best total net value after you account for admin time, reliability, payment speed, downtime, cancellation exposure, and your real effective hourly earnings. Not the headline rate. The actual result.
If you're a clinician, compare deals like an adult. What's the quoted rate? What deductions apply? How fast do you get paid? Who signs timesheets? What happens if the shift is cancelled late? Is travel covered? Is this one-off work or recurring block booking? And bluntly: how much do you hate admin? Your tolerance matters. Some people can run direct work beautifully. Others should not be within ten feet of their own invoicing process.

If you're an employer, the right metric isn't "what did we pay per hour." It's "what did we pay per filled, safely staffed, governable shift, and how much chaos did it create?" Fill rate, time-to-fill, no-show risk, governance burden, continuity, and internal staff time all belong in the calculation.

For many experienced locums, the smartest move is hybrid. Direct for stable recurring work where relationships are strong and everyone trusts each other. Agency for urgent bookings, remote sites, market access, and periods where you want someone else carrying the coordination burden. That isn't indecisive. That's efficient.
The people who do best in this market follow the money through the whole chain. Everyone else gets hypnotized by a bigger-looking number and misses where the losses really sit.
Red flags and negotiation truths most people ignore
Here are the warning signs people excuse when they shouldn't: vague rate breakdowns, fuzzy payment cycles, unexplained deductions, exclusivity clauses dressed up as "standard process," bait-and-switch shifts, and cancellation policies that somehow become detailed only after there's a problem. If the arrangement is unclear before the shift, it will be worse after the shift. Count on it.
And no, the highest advertised rate is not automatically the best deal. If you lose hours between bookings, cover your own travel, absorb late cancellations, and wait forever to be paid, that "great rate" can become a mediocre quarter very quickly.
The only comparison that matters is effective hourly income over a month or quarter. Not one glamorous Saturday night shift. Look at the whole period. Paid hours. Unpaid admin. Delayed cash flow. Failed bookings. Actual deductions.
Ask direct questions. Who handles compliance? Who pays if the shift is cancelled late? How quickly are invoices approved? Does block-booking change the rate? Is accommodation guaranteed or "usually available"? These aren't awkward questions. They're the entire game.
Money follows systems, not slogans. That's the part people resist because it's less satisfying than blaming "the middleman" or worshipping "independence." But it's the truth. And if you're serious about locum work, serious enough to treat it as a career strategy rather than a random stream of shifts, you need to look past the headline number and map who is carrying the cost, the hassle, and the risk.
That's where the money really goes.
