When you see a Consultant in a hospital, it is easy to assume they are there around the clock. However, the way their time is structured is quite specific. If you have ever wondered why your Consultant isn’t on the ward every day, or how their schedule is calculated, the answer lies in a system called Programmed Activities (PAs).
In the UK, a standard full-time NHS Consultant contract is based on 40 hours per week. But as with many senior roles, the reality of those hours is more nuanced than a simple 9-to-5.
Instead of being paid by the hour like many staff, a Consultant’s workload is divided into “Programmed Activities” or PAs.
What is a PA? One PA is equivalent to 4 hours of work (essentially half a day).
The Full-Time Standard: A standard full-time contract consists of 10 PAs per week.
The Math: $10 \text{ PAs} \times 4 \text{ hours} = 40 \text{ hours per week}$.
A Consultant’s week is rarely spent entirely at the bedside. Their 40 hours are usually split between “Direct Clinical Care” and “Supporting Professional Activities.” A typical split for a full-time doctor might look like this:
6 Clinical PAs (24 hours): This is the “frontline” work. It includes ward rounds, outpatient clinics, performing surgeries (theatre sessions), and emergency multidisciplinary meetings.
4 Non-Clinical PAs (16 hours): This time is dedicated to the “hidden” work of medicine. This includes teaching medical students, conducting life-saving research, clinical audits, governance meetings, and departmental management.
While the majority of this work occurs between 9:00 AM and 5:00 PM, Monday to Friday, many Consultants also participate in “on-call” rotas, providing emergency cover during nights and weekends.
While the contract says 40 hours, the timing of those hours can be highly flexible. Many modern hospital departments use a “Consultant of the Week” system to ensure continuity of care.
Intense Weeks: For one week, a Consultant might work 60+ hours, staying on the wards all day to see acutely ill patients and supervising the junior team.
Compensatory Weeks: To balance the 40-hour average, that same Consultant may have a much lighter schedule the following week—sometimes even being “off-ward” to focus on research or admin without needing to use their official Annual Leave.
The financial rewards for reaching the top of the medical profession are significant, reflecting the 10–15 years of rigorous training required to get there.
NHS Base Salary: As of the current pay scales, a full-time NHS Consultant earns between £94,000 and £126,000 per year based on their years of experience.
Total NHS Earnings: When you include “Clinical Excellence Awards” (bonuses for exceptional work), on-call supplements, and overtime (additional PAs), the average NHS Consultant salary rises to approximately £143,000.
Private Practice: Many Consultants choose to work beyond their 40 NHS hours. By seeing patients privately or performing medicolegal expert witness work in the evenings or on weekends, their total income can increase substantially, often reaching well into the mid-six figures.
In short, a full-time hospital Consultant is contracted for 40 hours a week, divided into ten 4-hour blocks.
Whilst they are well-compensated for this time, the complexity of the role means they are often balancing direct patient care with the essential administrative and educational tasks that keep the hospital running safely.
