All physicians employed by NHS Online, the nation's first entirely virtual hospital trust, must concurrently retain positions at other NHS institutions, and the amount of time they may devote to the new service is strictly limited. The measures were outlined at NHS ConfedExpo and represent an attempt to answer a question that has followed the project since its inception: how does the health service expand digital capacity without weakening the physical one?

The trust, announced by Prime Minister Sir Keir Starmer in September 2025, will provide care for conditions that clinicians have agreed can be safely diagnosed and managed virtually. Patients will have the option of using NHS Online when their GP makes a referral for specialist care, receiving treatment from doctors across the country directly through the NHS App, without leaving their home or waiting for an in-person appointment. The service is expected to begin offering specialist planned care through the NHS App from 2027.

NHS Online has been projected to deliver the equivalent of up to 8.5 million appointments and assessments within its first three years, four times more than an average trust, with initial focus on planned treatment areas with the longest waits. The government sees it as a means of reducing the backlog through digital scale, not additional estate or headcount.

But the structural question of where those clinicians come from has concerned workforce bodies and NHS leaders in equal measure. The fear is not hypothetical. The NHS already operates with significant staffing deficits, and a new trust that can offer doctors and nurses the flexibility of remote working risks becoming an attractive exit from demanding ward environments.

NHS Online non-executive director Omar Din, speaking at NHS ConfedExpo, said the trust has "really good ideas about how not to drain the system of its resources." He confirmed that safeguards would be put in place, adding: "You must be working in the NHS if you're going to work in NHS Online; there's only a percentage of your time which you'll be able to work within NHS Online, to safeguard our trusts and other parts of the system against being drained of those very important clinical commitments that we already have."

The specifics of that percentage cap have not been published. How it will be calculated, monitored, and enforced across what will be an inherently dispersed workforce remains an open question. A clinician splitting shifts between a busy district general hospital and virtual consultations booked through an app will require administrative tracking that no existing NHS rota system was designed to provide.

The challenge is compounded by the wider state of the workforce. NHS staff numbers in England grew by only 1,200 in the year to March 2026, the lowest annual growth in thirteen years, while the number of people aged 75 and over is projected to increase by 19 per cent over the next decade. A BMA report published this year found that eight in ten staff surveyed had attended work when unwell at least once in the previous three months. It is into this environment that NHS Online will ask clinicians to take on a second institutional commitment.

Critics of NHS digital reform have already flagged the risk. Dr Charles Goss, chair of the NHS Health at Work Network, has warned that technology cannot be expected to solve workforce pressures if introduced in ways that add to staff workload and stress, noting that stressed workers are already appearing in occupational health clinics as a result of digital transformation. A time cap addresses the quantity of hours a clinician can give; it does not address the cognitive load of managing obligations across two distinct institutional settings.

Tests, scans, and procedures will continue to take place at healthcare sites closer to patients' homes, while clinicians will be able to triage patients and review notes remotely, potentially outside office hours, without the patient being present. That flexibility is part of the appeal for staff and this contributes to the issue as well. Virtual work conducted outside office hours may technically fall within a percentage cap while still eroding the recovery time that an overstretched workforce cannot afford to lose.

NHS Online's leadership has committed to the safeguards. The practical test of whether this project adds capacity to the NHS or subtly redistributes the burden will be whether the structures required to make them effective can be built before the 2027 launch across a trust with no physical premises and a workforce borrowed from institutions that already have too little slack.
