From SAS to Consultant: what the transition actually looks like

Eligible is not the same as appointed

By the time a doctor reaches the end of the Portfolio Pathway, the assumption is understandable: the hard evidence-building work is behind them, the GMC and the relevant Royal College have confirmed the portfolio meets the required standard, and the Specialist Register entry has come through. It feels like the finish line. In terms of what the doctor is legally permitted to do next, it is a genuine and significant milestone. In terms of actually becoming a Consultant, it is closer to a starting gun.

Since 1 January 1997, GMC Specialist Register entry has been a legal requirement to take up a substantive, fixed-term or honorary Consultant post in the NHS, a fact covered in detail in our article on Specialist Grade vs Consultant. What that requirement does is remove a barrier. It does not create a post, advertise one, shortlist you for it, or appoint you into it. Those steps happen through the ordinary NHS medical recruitment process, the same one that applies to a doctor with a UK CCT, and they are not shortened or waived because you arrived at Register entry through the Portfolio Pathway rather than training.

This distinction matters most for the two groups the Portfolio Pathway is built around: senior SAS doctors, and non-substantive Consultants already doing Consultant-level clinical work on a locum, fixed-term or trust-grade contract. Both groups can reasonably feel, by the time Register entry arrives, that they are already doing the job. What follows in this article is an honest account of why that feeling, correct as it usually is about the clinical substance, does not translate into an automatic change of contract.

Why there is no automatic conversion to substantive

Doctors who have spent years as a non-substantive Consultant, perhaps on a series of fixed-term contracts in the same department, sometimes ask a fair question: if the Trust already knows the doctor, already relies on them clinically, and the only thing that changed is Register entry, why does the post need to be advertised and interviewed for again?

The answer sits in employment law rather than in any judgement about the individual doctor. NHS trusts (and, historically, the primary care trusts and strategic health authorities the same regulations originally covered) are required under the National Health Service (Appointment of Consultants) Regulations 1996 to appoint Consultants through a defined process, generally involving an Advisory Appointments Committee. NHS foundation trusts, which now employ the majority of NHS Consultants, are not bound by the same statutory duty, but in practice the great majority still run an equivalent process voluntarily, for the same reason most employers run a fair and defensible recruitment process for any senior appointment: it protects the Trust, the department, and the doctor appointed.

Two doctors with identical portfolios and identical clinical standing can go through this process differently only in how smoothly it runs, not in whether it runs at all. Understanding this in advance changes how doctors approach the months around Register entry: rather than treating the appointment as a foregone conclusion, treat it as a genuine, winnable competition that your Portfolio Pathway evidence has prepared you well for.

Advisory Appointments Committees: the process behind almost every appointment

An Advisory Appointments Committee, almost always shortened to AAC, is the panel constituted to interview and recommend candidates for a Consultant post. Its defining feature, and the reason it exists as a distinct concept rather than an ordinary NHS interview panel, is external representation: each Medical Royal College nominates independent representatives to sit on AAC panels within their specialty, in England, Wales and Northern Ireland also for certain non-training specialty doctor posts. That representative is there to provide specialty-specific quality assurance of the shortlist and the interview, independent of the employing Trust.

Job descriptions for AAC-assessed posts are typically submitted to the relevant Royal College for review before advertising, and college approval of a job description generally holds for around twelve months, useful to know if a post is re-advertised after an unsuccessful first round. Employers are usually expected to give the college reasonable notice, often several weeks, to arrange a representative for the panel date, which is one of the practical reasons a Consultant appointment process can take longer to schedule than an SAS or Specialist Grade interview.

For doctors who have come through the Portfolio Pathway, the practical implication of the AAC is reassuring rather than daunting. The evidence a strong Portfolio Pathway application is built on, structured referee reports, workplace-based assessments, a coherent structured CV, is close to what an AAC panel is looking for anyway. Our articles on structured reports and referees and the structured CV format are as relevant to preparing for a Consultant interview as they were to the original application.

Step by step: from GMC decision to your first day as Consultant

The sequence below is the typical shape of the transition for a doctor moving from a non-substantive Consultant, Specialist Grade or senior SAS post into a substantive Consultant appointment once Register entry is confirmed. The exact order and timing vary by Trust, but the stages themselves are consistent.

Not every stage applies to every doctor in the same order. A doctor who has been acting up in a Consultant role, or whose department has been planning the substantive conversion for some time, may find several stages happen close together. A doctor applying to a different Trust entirely will usually experience the full sequence with no shortcuts.

Acting up: the interim step some doctors take

Between finishing Portfolio Pathway evidence-building and formal Register entry, some SAS and Specialist Grade doctors take on Consultant-level responsibilities informally, most commonly by acting up: covering the clinical and managerial duties of an absent Consultant colleague for a defined period. BMA guidance on acting up in England is clear that a doctor doing this is entitled to be paid at the rate of the role they are actually performing for the period they perform it, whether that role is specialist or Consultant.

For doctors who are already Register-entered and weighing up whether to accept an acting-up period before a substantive post becomes available, the honest calculation is usually about experience and visibility rather than pay: the pay entitlement is the same either way for the period covered, but the exposure to Consultant-level service leadership, MDT chairing, and rota management can genuinely strengthen an application when the substantive post is eventually advertised.

What changes in your contract, pay and job plan

The move from SAS, Specialist Grade or non-substantive Consultant terms onto a substantive Consultant contract is a genuine contractual change, not an uplift within the same agreement. In most of the UK this means moving onto the 2003 Consultant contract framework or the relevant national equivalent, with its own pay scale, on-call and job planning provisions.

None of this happens by default when the appointment letter is signed. If your existing job plan has informal arrangements, a flexible SPA session here, an unofficial reduced on-call commitment there, do not assume they transfer. Treat the job planning meeting for your new Consultant post exactly as our article on job plan flexibility recommends for any new post: get the specifics agreed and written down, rather than relying on a verbal understanding carried over from your previous role.

Contractual notice periods for Consultant posts are commonly longer than at SAS or Specialist Grade level and will be set out in your new contract of employment. Check the specific figure with your prospective employer's HR or medical staffing team rather than assuming it matches your current post, and factor it into any handover planning with your current department.

Realistic timing: how long the whole transition takes

Doctors planning around the end of a Portfolio Pathway application often ask how long the gap will be between Register entry and starting as a substantive Consultant. There is no single reliable figure, because so much depends on whether a post already exists and needs converting, or has to be created and advertised from scratch, and on how quickly a job description can clear Royal College review if this has not been done for the post before.

Put together, doctors converting their own post in a supportive department sometimes move from Register entry to a substantive start date within two to three months. Doctors applying for a genuinely new post, particularly at a different Trust, should reasonably expect the process to take longer, and building that realistic expectation into personal and family planning avoids the frustration of assuming Register entry itself is the finish line. This is one of several reasons our article on what a genuinely supportive Trust looks like is worth reading well before you reach this stage, not after.

Support during the transition: induction and mentoring

The clinical and leadership step up from senior SAS or non-substantive Consultant work to a full substantive Consultant post is real, even for doctors who have effectively been doing Consultant-level work for years. Several Royal Colleges run structured support for this transition, and it is worth using deliberately rather than assuming you should already know how to navigate it.

The international doctor's version of this transition

For internationally-trained doctors, the appointment process described in this article, the AAC, the job planning meeting, the contract change, is identical regardless of where you trained or worked before the UK. What is usually different is everything that led up to Register entry in the first place. Direct-from-overseas Portfolio Pathway applications, without any period of UK clinical practice, are genuinely rare and difficult, because the evidence the route requires is built around UK practice, governance and working culture that is hard to demonstrate from outside the system.

Most internationally-trained doctors who reach this stage do so after a period working in UK SAS or Specialist Grade posts first, building the evidence base described throughout this site while also becoming genuinely familiar with the NHS systems an AAC panel will expect a Consultant candidate to understand well. Our article on translating overseas evidence covers the earlier stage of this journey in more detail, and a dedicated article on the international doctor's bigger picture sets out how this transition fits into the wider decision of moving to the UK.

Before you apply: a practical readiness checklist

The list below is deliberately practical rather than clinical. Most doctors reaching this stage already have the clinical standing; what catches people out is the surrounding process.

None of this replaces the clinical and evidential substance of the Portfolio Pathway itself. It sits alongside it, and doctors who plan for the appointment process with the same care they gave the portfolio tend to find the transition considerably less stressful than those who assume Register entry is the end of the work.

Where this sits in the recruitment bridge series

This is the fifth article in the Tier 6 recruitment bridge cluster, which looks at how the working environment, contract type and appointment process around the Portfolio Pathway shape a doctor's actual trajectory, not just the formal evidence requirements. Understanding the appointment process honestly, rather than assuming Register entry is self-executing, is one of the most practically useful things a doctor can do in the final stretch of their Portfolio Pathway.

For doctors earlier in the process, our articles on eligibility, realistic timeline, and costs and hidden expenses give the wider context. Doctors actively building evidence will find the four GMC domains, Capabilities in Practice, and leadership and management evidence the most directly useful next reading, since leadership evidence in particular tends to matter as much at AAC interview as it did in the original portfolio.

Doctors closer to submission or already through it will get more from our guides to the GMC Online application walkthrough, the Royal College assessment process, the 24-month application window strategy, and, for anyone who has faced a setback along the way, our articles on deferrals and additional evidence requests and appeals and reapplication.
