When Should Practices Hire Locums? Key Signs

A nurse calls in unwell before morning surgery. A hygienist’s annual leave has been approved, but the replacement has not been arranged. A dentist leaves with short notice and a full diary still needs care. When should practices hire locums? Usually, the right time is before a staffing gap begins to affect patient safety, clinical capacity or the experience of the wider team.

For busy NHS, mixed and private practices, locum cover is not simply a last-minute contingency. Used well, it is an operational tool that protects the diary, supports permanent staff and gives patients continuity of care when plans change. The decision is rarely about filling every empty slot. It is about recognising which gaps create risk and acting early enough to keep the practice running safely.

When should practices hire locums?

Practices should consider locum cover whenever the absence of a GDC-registered professional would compromise safe delivery, create unmanageable pressure for colleagues or lead to avoidable cancellations. The urgency will depend on the role, the practice’s appointment book and the level of cover already available internally.

A single missing dental nurse, for example, may mean a surgery cannot run as planned if no appropriately trained colleague is free to assist. The impact is more than an inconvenient rota change. It can affect decontamination processes, chairside support, safeguarding responsibilities, patient reassurance and the clinician’s ability to work efficiently.

For hygienists, therapists and dentists, the consequences are often visible immediately in lost appointments. Cancelling a list may protect safety in the moment, but repeated disruption can weaken patient confidence and reduce access to care. Patients who have waited weeks for an appointment may not be able to return easily, particularly where treatment plans or ongoing periodontal care are involved.

The best trigger is therefore not simply "we are short-staffed". It is: can we deliver the planned day safely, compliantly and without placing unreasonable strain on the team? If the answer is no, arranging a suitably vetted locum is usually the responsible option.

Cover planned leave before the diary is affected

Annual leave, maternity leave, training days and planned medical appointments are the clearest opportunities to arrange locum support in advance. They should not become urgent staffing problems simply because they were known weeks or months beforehand.

Planned cover is particularly valuable when the absent team member holds a specialist function or works closely with a specific clinician. A practice may be able to redistribute some tasks for a day, but a prolonged absence can quickly lead to fatigue, reduced efficiency and a growing backlog. Booking a locum for the busiest sessions, rather than every day of an absence, can be a sensible balance where budgets are tight.

It also gives the practice time to share practical information before the locum arrives. Surgery allocation, software access, local protocols, infection prevention arrangements and the day’s clinical expectations all matter. A prepared locum can contribute quickly; an unprepared one may still be capable, but the team will spend more time settling them in.

Act quickly when sickness creates a clinical gap

Unexpected sickness is where a reliable dental staffing partner matters most. Last-minute absence is stressful because practice managers must protect safety, communicate with clinicians and decide whether patients can still be seen, often before the first appointment of the day.

Not every sickness absence requires a locum. A small practice with spare capacity elsewhere in the rota may be able to adjust safely for a short period. However, relying on goodwill and overtime as the default response is rarely sustainable. If colleagues are repeatedly asked to absorb extra duties, morale can fall and further absence becomes more likely.

Fast cover is especially important where a missing nurse would prevent surgeries from operating, or where an absent clinician would leave a significant treatment list uncovered. A fully vetted, GDC-registered locum can help retain booked appointments while giving the permanent team the support they need to focus on patients.

For practices across Birmingham and the wider West Midlands, regional availability can make a material difference to short-notice decisions. A locum who understands dental practice routines and can travel realistically to the site is more useful than a speculative booking that may not materialise.

Use locums to manage peaks in demand

Recruiting a permanent team member is the right answer for a long-term, predictable need. Yet temporary increases in workload do not always justify a permanent hire. New patient campaigns, extended opening hours, a returning clinician’s growing list, school holiday demand or a short-term NHS capacity requirement may create a genuine need for extra clinical support without changing the practice’s ongoing establishment.

Locums offer flexibility in these periods. A practice might bring in a dental nurse for selected high-volume days, or arrange hygiene and therapy sessions to reduce a waiting list. The value lies in matching the cover to the pressure point, rather than committing to a staffing model that may not be needed six months later.

There is a trade-off. A locum rate can appear higher than the day-to-day cost of a permanent employee. But that comparison is incomplete if it ignores lost production, cancelled treatment, patient dissatisfaction and the pressure placed on existing staff when no cover is secured. The relevant question is whether the cost of cover is proportionate to the risk and lost capacity created by the gap.

Protect continuity during recruitment and transitions

A resignation does not always mean a practice should immediately reduce its service. In fact, the notice period and the weeks after a departure can be the ideal time to arrange locum support while a permanent search takes place.

This is particularly helpful where the departing employee carries knowledge of a busy diary, works in a difficult-to-recruit role or has responsibilities that cannot be transferred safely at short notice. Locum cover gives the practice breathing room to make a considered permanent appointment rather than accepting the first available candidate because the rota is under pressure.

The same approach applies when a new permanent employee has accepted an offer but cannot start straight away. A temporary placement can bridge the gap and keep expectations realistic for patients and the team. In some cases, a practice may also use regular locum sessions to assess how its clinical demand develops before deciding whether a permanent post is needed.

Do not wait for cancellations to become routine

One isolated cancellation may be unavoidable. A pattern of cancelled hygiene sessions, delayed treatment or last-minute changes to dentists’ lists is different. It is a warning that the current staffing plan has too little resilience.

Practice managers should watch for signals such as recurring overtime, staff being moved between surgeries at short notice, clinicians working without their usual support, waiting lists growing, or patients being asked to rebook more than once. None of these automatically requires agency cover, but together they point to an operational issue that needs attention.

A useful internal question is whether the practice is coping, or merely getting through the day. Coping means staff have adequate support, standards remain consistent and patients receive the service they were promised. Merely getting through the day often depends on rushed handovers, stretched colleagues and repeated compromises that eventually become visible to patients.

What to check before booking a dental locum

Speed matters, but it should never replace proper checks. The right locum should be able to work safely from the moment they arrive, with credentials and role suitability confirmed before the shift begins. This is why a specialist dental agency is different from a general temporary staffing provider.

Before confirming cover, make sure there is clarity around four areas:

• The exact role, clinical duties, start and finish times, and whether the booking is for a single day or ongoing support.

• Current GDC registration, relevant experience and the compliance checks required for that role.

• The practice’s systems, surgery setup, infection prevention procedures and any local protocols the locum needs to follow.

• A named contact on site who can provide a concise induction and resolve practical questions promptly.

The practice also has a part to play in making a placement successful. Clear communication about the day, realistic expectations and a welcoming introduction help a locum integrate quickly. This is not about lowering standards for temporary staff. It is about giving an appropriately qualified professional the information needed to meet those standards.

Build locum cover into the rota plan

The strongest practices do not only call for help when the diary is already at risk. They identify critical roles, note predictable pressure points and keep a clear process for requesting cover. That may include pre-booking for planned leave, setting an internal escalation point for sickness absence and reviewing recurring gaps after each month.

Peace of Mind Dental Staffing supports practices with fast, reliable 24/7 cover from fully vetted GDC-registered dental professionals, helping teams respond when staffing changes threaten patient flow. The aim is not simply to fill a vacancy, but to place a professional who is suitable for the practice, the role and the clinical day ahead.

A well-timed locum booking gives a practice more than an extra pair of hands. It gives the team space to maintain safe standards, patients confidence that their care remains on track, and managers the ability to make staffing decisions calmly rather than under pressure.
