NHS Probation Period Explained

Starting a new NHS job comes with enough to think about without also being unsure what "probation" actually means for you day to day — how long it runs, what a review meeting really involves, whether you're as exposed as it can feel, and what "failing" it actually looks like procedurally. This guide covers the general shape most NHS trust probation policies follow, while being honest that the exact detail — length, notice, and exactly how a concern is handled — genuinely varies by trust and sits in your own contract, not in a single national rule.

How long NHS probation typically runs

There is no single length of probation fixed by Agenda for Change itself — it's a matter of local trust policy, written into your individual contract of employment. In practice, six months is by a clear margin the most common length used across NHS trusts for most Agenda for Change roles, though you'll occasionally see shorter periods for some posts. Doctors and dentists on national training programmes, and some other nationally-contracted groups, often sit outside the general trust probation policy entirely, following their own training programme's induction and assessment arrangements instead.

What actually happens during probation

Most NHS probation policies are built around structured review points rather than simply leaving you to find out at the end whether you've passed. A typical pattern looks something like this, though the exact number and timing of reviews varies by trust:

None of this is designed to be a trap — the structure exists precisely so concerns get raised and addressed early, with support, rather than surfacing for the first time as a shock at the very end of six months. If you're ever unsure how you're actually doing partway through probation, it's entirely reasonable to ask your manager directly for honest feedback rather than waiting for the next scheduled review.

Notice periods during probation

One of the most commonly overlooked details in a new NHS contract is that the notice period that applies during probation is usually shorter than the notice that applies once you've completed it. This cuts both ways — you generally need to give less notice to leave during probation, and your employer generally needs to give you less notice to end your employment during this period too.

Exactly where your own notice period sits within that general pattern depends on your specific contract and your trust's own policy, so treat the figures above as a general shape rather than your personal answer — check your actual written statement of terms, which should set out the applicable notice for both the probationary and confirmed stages of your employment.

Extensions: when, and why they shouldn't be open-ended

Probation can usually be extended, but a well-run policy treats this as an exception that needs a genuine reason, not a routine way of avoiding a decision. Common, legitimate reasons for an extension include:

• • Significant absence during probation — for example extended sickness absence, or a lengthy period of leave — that genuinely prevented a fair assessment of your performance over enough working time.
• • Specific, clearly identified concerns that a manager reasonably believes could be resolved with more time, additional training, or closer supervision, rather than concerns serious enough to justify ending employment now.
• • A delayed or missed review through no fault of your own — for example if your manager was unavailable at the scheduled review point — where it wouldn't be fair to let the original end date pass without the review actually happening.

What a genuine extension should come with is clarity: a specific new end date, clearly stated reasons for the extension, and — where the extension follows a performance concern — clear, written objectives for what needs to improve and by when. An extension with no clear end point, no clear reasons, and no clear plan is worth questioning directly with your manager or raising with your union representative, since it leaves you in an uncertain position for longer than is fair.

Failing probation vs a disciplinary dismissal: a genuinely different process

This is the distinction that causes the most confusion, and it matters practically as well as emotionally. Most NHS trust probation policies explicitly carve conduct and performance issues arising during probation out of the trust's normal disciplinary and capability procedures, and deal with them instead under the probation policy itself.

The practical effect of this distinction is that ending someone's employment during probation typically doesn't require the same formal investigation-then-hearing sequence a disciplinary dismissal would — which is one reason probation can feel like it carries less procedural protection than employment does once you're confirmed. That said, a sufficiently serious matter arising during probation — for example a serious safeguarding, safety, or conduct concern — can still be escalated into the full disciplinary process at a trust's discretion, rather than being confined to the lighter-touch probation route regardless of severity. If you're ever told a probation concern is actually being treated as a disciplinary matter, that's worth clarifying explicitly, since the two processes carry different rights and different stakes.

Your rights during the probation process

• • Clear objectives — you should know, in writing, what's actually expected of you and what a review is assessing you against, not be left to guess.
• • The right to be accompanied at formal review or decision meetings — most trust probation policies extend this to a trade union representative or work colleague, similar to the statutory right that applies to disciplinary and grievance hearings.
• • Written outcomes — a review or decision meeting should be followed by something in writing confirming what was decided and why, not left as a verbal impression you have to rely on later.
• • A right of appeal if your employment is ended during probation — check your own trust's policy for the specific time limit, which is often short.
• • A reasonable chance to improve where a genuine, addressable concern is raised partway through probation, rather than being failed at the final review for something never previously mentioned.

A changing legal backdrop: qualifying service for unfair dismissal

Under the law as it currently stands, an employee generally needs two years' continuous service to bring an ordinary unfair dismissal claim — meaning most staff on probation, almost by definition, don't yet have access to that particular legal protection if their employment ends during or shortly after it (a handful of protections that need no qualifying service at all, such as whistleblowing dismissal and certain discrimination-related dismissals, are the exception, not the rule).

This is genuinely changing, though not in the way originally proposed. Early versions of what became the Employment Rights Act 2025 floated making unfair dismissal a "day one" right for everyone, alongside a new statutory "initial period of employment" with a lighter-touch dismissal process — but that specific proposal was dropped from the final Act. What has been confirmed instead is a reduction in the qualifying period from two years to six months, due to take effect from 1 January 2027. As that date approaches, this will bring a meaningful proportion of longer probation periods within reach of ordinary unfair dismissal protection for the first time — worth being aware of if your own probation is likely to still be running, or to have only recently ended, around that date.
