There is a version of this story that plays out in GP surgeries across the UK every year. A partner goes down with a serious illness. The remaining partners absorb the workload for a week, then two, then a month. Eventually, a locum doctor is brought in to cover — at a daily rate that quickly runs into thousands of pounds. The practice had no locum insurance. By the time the absent partner returns, the surgery is carrying a five-figure unbudgeted cost with no mechanism to recover it.

This is not a rare scenario. It is one of the most common and least anticipated financial pressures a medical practice can face, and it is one that adequate insurance cover is specifically designed to prevent.

What Is Locum Insurance?

Locum insurance — sometimes called locum cover or GP locum insurance — is a specialist form of business continuity insurance designed for medical practices. It is usually provided by insurance companies, such as MIC, who specialise in policies for healthcare providers and medical professionals. In broad terms, it reimburses the cost of hiring a locum (a temporary substitute doctor) when a regular GP or clinical partner is unable to work due to illness, injury, or surgery.

The cover typically activates after a defined waiting period — commonly seven or fourteen days — and pays out a daily or weekly benefit up to an agreed cap for as long as the absence continues, subject to the policy’s maximum benefit period. Some policies extend beyond GP absences to cover other clinical staff on whose regular attendance the practice depends, such as nurse practitioners or salaried doctors.

The policy is taken out by the practice itself, not by the individual doctor, which distinguishes it from personal income protection insurance. Where a GP’s personal income protection covers their own salary if they cannot work, locum insurance covers the practice’s cost of finding and funding a replacement for them. Both can be held simultaneously and serve complementary purposes.

Why UK GP Surgeries Are Particularly Exposed

Understanding why locum insurance matters requires understanding the business model under which most GP partnerships operate. In England, GP practices typically hold a General Medical Services (GMS) or Personal Medical Services (PMS) contract with NHS England. Under this arrangement, the practice receives a capitation-based income — broadly, a payment per registered patient — in exchange for delivering a defined range of primary care services. The critical point is that this income continues regardless of whether the practice is operating at full clinical capacity.

That might sound like a protection, but it is actually a source of risk. A practice receiving income for 7,000 patients must still service those 7,000 patients whether it has two working GPs or four. When clinical capacity falls, the options are stark: accept a dangerous and unsustainable increase in workload for remaining staff, reduce patient access and risk regulatory consequences, or spend money the practice has not budgeted to bring in external cover.

GP partnerships are also small businesses in a way that larger organisations are not. A two- or three-partner practice has almost no redundancy built in. If one partner is absent for six weeks, that is a 33% to 50% reduction in core clinical capacity. There is no large pool of colleagues to absorb the shortfall and no corporate HR department to manage the situation. The remaining partners face both the clinical pressure and the direct financial impact simultaneously.

What Locum Insurance Actually Covers

Policy terms vary between insurers, and the detail matters considerably. Most comprehensive locum insurance policies for UK GP practices will cover:

GP partners absent through illness or injury — the primary and most common use case. Cover typically begins after the agreed deferred period and continues for the duration of the absence, up to the maximum benefit period, which commonly ranges from 26 to 52 weeks per incident.

Post-hospitalisation recovery — periods of convalescence after surgery or hospital admission, where a GP is medically signed off but not yet fit to return to full clinical duties.

Maternity, paternity, and adoption leave — many policies offer optional extensions that cover the cost of locum cover during planned parental leave. This is particularly relevant given the high proportion of female GPs in the UK workforce and the planning difficulties that extended maternity absences create for small partnerships.

Jury service — an often-overlooked inclusion. Jury service can last weeks in complex cases, and a GP summoned for an extended trial represents a genuine and unforeseeable absence.

Bereavement leave — some policies include a short-period benefit for absences following bereavement.

What most policies do not cover includes pre-existing conditions that were known at inception, absences that fall within the deferred period, and situations where a locum is not actually hired (many policies require the expense to be incurred, not simply that the absent doctor’s workload is redistributed).

The Real Cost of Going Without

The case for locum insurance becomes most concrete when you consider what locum cover actually costs in the open market — because this is the bill the practice faces without insurance.

Locum GP daily rates in the UK vary by region and availability, but a typical session rate runs from £450 to over £700 for a half-day surgery session. A full-time equivalent locum working five days per week represents a weekly spend of £2,000 to £4,000 or more. Over the course of an eight-week absence — not exceptional for a serious illness, surgery, or recovery — a practice could be looking at between £16,000 and £32,000 in locum fees alone.

These figures have increased markedly in recent years as GP workforce pressures have intensified. Locum availability in many parts of the country is constrained, and when supply is tight, rates rise. A practice without insurance and without a relationship with a locum agency may find itself competing for available doctors in a seller’s market.

The Indirect Costs Are Equally Damaging

The direct locum fee is only part of the picture. Consider the broader financial and operational consequences of an unplanned extended absence:

Partner earnings reduction — in a GP partnership, the partners share the net profit of the practice after all expenses, including locum costs, are met. An uninsured locum spend comes directly off the bottom line, reducing the drawings of every partner. In a small practice, this can represent a meaningful personal income reduction for partners who are already covering additional clinical work.

CQC regulatory risk — the Care Quality Commission expects GP practices to maintain safe staffing levels and adequate patient access. A practice operating at reduced capacity for an extended period without a credible management plan risks an adverse CQC inspection rating. A practice rated ‘Requires Improvement’ or ‘Inadequate’ faces enhanced monitoring, mandated improvement plans, and reputational damage that can affect patient registration numbers — which directly affects capitation income.

Enhanced Services income at risk — many practices supplement their core GMS income by delivering enhanced or locally commissioned services: extended hours, minor surgery, diabetic reviews, and similar. Delivering these services requires adequate clinical staff. An absent partner can mean a practice is unable to fulfil the activity thresholds required to claim this income, and in some cases may be required to return payments already received.

Recruitment and retention pressure — remaining partners working at unsustainable intensity are at elevated risk of burnout and illness themselves. An unmanaged absence in a small practice can trigger a cascade: the partners covering extra work become exhausted, their own health deteriorates, and the practice faces a second or third absence before the first has resolved. This is not a hypothetical — it is a well-documented pattern in general practice.

Continuity of care — while this is primarily a clinical rather than financial concern, disrupted continuity has downstream financial effects. Patients who cannot access their practice promptly seek care through NHS 111, walk-in centres, or A&E. Commissioners and ICBs (Integrated Care Boards) are increasingly attentive to primary care access data, and a practice with a persistently poor access record faces scrutiny that can affect contract negotiation.

The Specific Risks of Underinsurance

Holding a locum insurance policy is not, by itself, sufficient protection. Many practices that believe themselves covered discover on making a claim that their cover is inadequate in one of several common ways.

Insufficient benefit levels — if the daily benefit cap is set too low relative to actual market locum rates, the policy covers only part of the cost. A policy that pays £300 per day when the market rate for a locum in the practice’s area is £600 leaves the practice self-funding half of every working day. Benefit levels should be reviewed annually against current local locum rates, not set at inception and forgotten.

Benefit periods that are too short — a maximum benefit period of 13 weeks may seem generous until a GP is absent for six months following a cardiac event or major orthopaedic surgery. Recovery timelines for serious conditions regularly exceed what practices anticipate, and a policy that expires mid-absence leaves the practice unprotected for the remainder.

Deferred periods that are too long — while a longer deferred period reduces the premium, a 28-day wait before cover activates means the practice absorbs the first month of locum costs entirely from its own resources. For a smaller practice, this can mean four weeks of unbudgeted expenditure before any benefit is received.

Exclusions for known conditions — a partner who has a history of back problems, cardiovascular disease, or mental health conditions may find that absences related to those conditions are excluded from cover. This underlines the importance of taking out cover before conditions arise, not after.

Locum Insurance Within the Broader Risk Picture

Locum insurance sits within a wider framework of risk management that a well-run GP practice should have in place. It complements — but does not replace — several other protections:

Practice partnership agreement — a properly drafted partnership agreement should specify how locum costs are allocated if a partner is absent, what happens if a partner is unable to return to practice, and the financial arrangements that apply in long-term incapacity. Without this, disputes about cost-sharing can arise at an already difficult time.

Individual GP income protection — as noted earlier, a partner’s own income protection policy covers their personal income if they cannot work. This is distinct from the practice’s locum insurance but equally important. A GP whose personal income protection kicks in can support themselves financially without drawing from the practice’s reserves, which in turn protects the partnership.

NHS Pension Scheme ill-health provisions — GPs who are permanent employees or partners contributing to the NHS Pension Scheme have access to ill-health retirement benefits if they are permanently unable to work. Understanding these entitlements is relevant to the practice’s longer-term planning if a partner faces a career-ending illness or injury.

Choosing the Right Policy

The specialist nature of GP practice means that locum insurance is not a product that generalist commercial insurance brokers always understand well. Practices are best served by brokers with specific experience in medical practice insurance, who understand the nuances of GP partnership structures, NHS contract income, and the employment status of different clinical staff.

Key considerations when reviewing or selecting a policy include whether the benefit is paid as a fixed daily/weekly sum or as reimbursement of actual locum costs incurred, how the policy treats pre-existing conditions of existing partners, whether locum availability is a condition of the benefit (if no locum can be found, does the policy still pay?), and how claims are handled in practice, not just in principle.

Conclusion

Locum insurance is not a luxury product for large, well-resourced practices. It is a fundamental piece of financial risk management for any GP surgery that operates as a partnership — which is to say, the majority of NHS primary care in the UK. The cost of adequate cover is modest relative to the exposure it addresses. The cost of being without it, when a partner goes down for a month or more, is immediate, concrete, and in many cases significantly damaging to a practice that was not financially structured to absorb it.

The GP workforce is under sustained pressure. Absence rates are high. Locum rates have risen sharply. The conditions that make locum insurance valuable are not improving. For any practice that has not reviewed its cover recently, or has not reviewed it at all, the question is not whether the risk is real — it is whether the practice can afford to carry it uninsured.
