How Easy Is It to Register as a Locum Doctor?

Let's answer the question you're really asking

If you're wondering whether registering as a locum doctor means drowning in paperwork and waiting weeks to start, we fully understand, and we're going to be completely honest with you.

Compliance is thorough, because it has to be. But 'thorough' doesn't have to mean slow or painful, and with the right support it really isn't.

This page shows you what registering with Medacs Healthcare actually involves, how long it takes, and exactly what you need to get you working faster and most importantly, so you know exactly what to expect.

Why compliance is safe in our hands

Medacs Healthcare is one of the UK's longest-established healthcare recruitment agencies, trusted to place doctors across the NHS and private sector for more than 35 years.

Compliance and clinical governance sit at the very heart of what we do.
We're an approved supplier on all the major NHS frameworks, including the Crown Commercial Service (CCS), HealthTrust Europe (HTE) and NHS Scotland national procurement, which is one reason the trusts you want to work in already recognise and trust us.

Our vetting and safeguarding processes are built to the standards the NHS and the GMC expect, and our dedicated in-house compliance team does nothing else but get clinicians safely and properly cleared to work.

That depth of experience is exactly why a process that can feel daunting on your own becomes genuinely manageable with us alongside you.

Why do doctors choose locum work?

Doctors choose locum work for many reasons.

We have listed the most common below:

Flexibility and control over their own schedule, working around family, study, or other commitments

Higher earning potential per shift compared to some substantive roles

Variety, experiencing different hospitals, teams and ways of working

A break from the pressures, politics or rota constraints of a permanent post

Bridging a gap, between training posts, after returning from abroad, or while deciding on their next move

Building a portfolio career, combining clinical work with education, research or other interests

Whatever the reason, locum work suits doctors who value autonomy and are comfortable trading a full-time, substantive role for more freedom.

That trade-off is the honest heart of it, and it's worth understanding properly.

The honest pros and cons of locum work

This is the part most guides skip over, or gloss with only the positives. We won't.
Here's the genuine, balanced picture, because knowing the downsides is exactly how you decide well.

The genuine benefits

Benefit	What it really means
Flexibility	You decide when and where you work. You can take time off when you want it, without asking permission. Flexibility doesn't mean unpredictability – long-term block bookings are available
Earning potential	Locum rates can be higher per shift than substantive pay, especially for hard-to-fill shifts and specialties
Variety and experience	Working across different settings broadens your clinical exposure and your CV g, governance and pricing are assessed against national standards
Autonomy	You're not tied into rota politics, and you can step away from a role that isn't working for you
Control over workload	You can work as much or as little as suits your life, and you can chosse to pick up more or less as things change

The honest trade-offs

And here's the other side, said plainly, because these matter just as much.

The genuine benefits

Trade-off	What to weigh up
Income can be less predictable	Work isn't always guaranteed.But working with an agency that has work in many NHS trusts and boards ensures you have options even in the quieter times.
No paid holiday or sick leave	Although you benefit from a higher than average hourly rate, as a locum you're not paid when you don't work.
Pension considerations	Pension arrangements differ from a substantive post, so it is essential you understand this (we cover this separately)
Less continuity	Although some agencies offer longer term placements and the opportunity to block book – many only offer last minute, ad-hoc shifts
Admin and compliance	You may have to manage your own compliance, tax and revalidation evidence, though a good agency will manage this for you and ensure you are up-to-date with the latest requirements.
It can feel isolating at times	Moving between teams means you're sometimes the new face. Some doctors love this, others miss the roots, this is a great opportunity to network and make friends and connections across different settings and services.

None of these should put you off.

For thousands of doctors, the freedom is more than worth it. But they're the real considerations, and any agency that pretends locum work is all upside isn't being straight with you.

How does locum work actually work?

Here is the registration process in 5 easy steps.

You register with an agency (or more than one), which handles your compliance and matches you to work.

You're offered shifts, sessions or fixed-term placements that suit your grade, specialty and preferences.

You choose what to accept. You're never obliged to take anything that doesn't work for you.

You work the shift, and submit a timesheet.

You're paid, usually weekly, either through PAYE, or an approved umbrella company.

💡 Top tip: Most doctors work through an agency because it handles the admin heavy parts, compliance, finding the work, and getting you paid, so you can focus on the medicine. A good agency should feel like a partner who knows you, not just a booking service.

What kinds of locum work are there?

There are lot's of different types of locum work.

The Main Types:

Type	What it involves
Ad-hoc shifts	Individual shifts booked as needed, maximum flexibility, ideal for topping up income or fitting around other work
Block Bookings	A run of shifts over a longer period of time – usually 3 – 6 months in advance, ideal for those clinicians who want a little more predictability and stability
Fixed-term placements	A defined block, weeks or months, offering more stability and continuity than one-off shifts
Specialty locum work	Roles matched to your specialty and grade, from SHO through middle grade to consultant level
Insourcing	Working as part of a surgical team brought in to add clinical capacity, often to reduce waiting lists

Is locum work right for you?

Only you can answer that, but in our 35+ years of experience here's what we would say.

Locum work tends to suit you if:

You value flexibility and autonomy more than the security of a fixed post

You enjoy variety and adapting to new teams and settings

You want to earn well for the hours you choose to work

You're at a transition point, between posts, returning to work, or building a portfolio career

Depending on the recruitment agency you choose it maybe for you if you prefer long-term team continuity, want the certainty of fixed-guaranteed monthly income, or would rather not manage any of your own admin.

And that's completely fine, there's no right answer, only the right answer for you.

Frequently Asked Questions

A locum doctor is a qualified doctor who works on a temporary basis, filling gaps where a hospital, GP practice or other provider needs a doctor but doesn't have a permanent one available.

The word 'locum' comes from the Latin for 'to hold the place of'.

Locum work can be single shifts, fixed-term placements, or ongoing flexible work.

For many doctors, yes, but it depends on what you value. The benefits are flexibility, higher potential earnings and variety.

The trade-offs are less predictable income, no paid holiday or sick leave, and managing your own admin.

If you value freedom and are comfortable with a little less certainty, it can be genuinely worth it.

Locum rates vary by grade, specialty, location and how hard a shift is to fill, and can be higher per shift than substantive pay.

How you're paid (PAYE, or umbrella ) also affects your take-home. We cover pay, IR35 and tax in detail on a separate page.

Generally no. As a locum you're paid for the work you do, so time off, whether holiday or illness, isn't paid.

This is one of the honest trade-offs of locum work, and it's worth planning a financial buffer for quieter or non-working periods.

Yes, many doctors do. Locum shifts are a common way to top up income, gain experience in other settings, or build a portfolio career alongside a substantive post.

The flexibility is one of the main reasons doctors choose locum work.

It can be, particularly for gaining experience, earning between training posts, or bridging a gap.

It's worth balancing income against maintaining training opportunities, and a good agency will help you find work that supports your development, not just fills a rota.

Take your time, and decide what's right for you

There's no rush, and no pressure. Locum work is a big decision, and the right choice is the one that fits your life, your finances and your goals.

If it's something you'd like to explore, we're here to help you think it through honestly, and if it's right for you, to make it happen.

That, more than anything, is the difference we make together.
