NHS Pre-Employment Occupational Health Checks Explained

Last updated September 2026 · Independent guidance, not affiliated with NHS England or DHSC

Short answer

An NHS occupational health check is a standard part of pre-employment screening, sitting alongside a DBS check and right-to-work verification. It generally involves a health declaration and, for many clinical roles, a check of your immunisation and vaccination status relevant to working with patients. Its purpose is to assess your fitness for the specific demands of the role you've been offered and to identify any reasonable adjustments that would help you do it safely — not to hunt for reasons to reject candidates. Exact immunisation requirements vary by role and trust and change over time, so this page explains the general shape of the process; for the current, authoritative standards, see NHS Employers' own pre-employment check guidance.

Alongside a DBS check and right-to-work verification, an occupational health assessment is one of the standard pieces of NHS pre-employment screening that most new starters go through once they've been offered a role. It tends to generate more anxiety than it probably should, mostly because people aren't sure what's actually being assessed or why. This guide explains the general concept, why immunisation status matters for many clinical roles specifically, and — most importantly — what occupational health's actual job is (and isn't) in the recruitment process.

What an occupational health assessment actually covers

In general terms, an NHS pre-employment occupational health check typically includes some combination of the following, though the exact depth and content varies depending on the specific role and its demands:

  • A health declaration questionnaire, where you disclose relevant medical history, current conditions and any medication that could affect your ability to do the role safely
  • For many clinical and patient-facing roles, a check of your immunisation and vaccination status against current guidance relevant to that clinical setting
  • An assessment of fitness for the specific physical and other demands of the role — manual handling, shift patterns, or particular working environments, for example
  • Where relevant, a conversation about reasonable adjustments that would let you perform the role safely and effectively

The exact combination and depth of these elements depends heavily on the role itself — a ward-based clinical post with direct patient contact is generally assessed differently from a desk-based administrative role, even though both may go through some form of occupational health process.

Why immunisation status matters for clinical roles

For many roles involving direct patient contact, part of the reasoning behind checking immunisation status is straightforward: it protects both you and the patients you'll be working with from certain infectious diseases that can spread more easily in healthcare settings. This is a well-established, sensible principle in healthcare occupational health generally, not something specific or unusual to any one trust.

What we're deliberately not doing on this page is listing specific immunisations, because exact requirements vary by role, by clinical setting, and by current public health guidance — and that guidance is reviewed and can change. Rather than risk publishing something that's out of date by the time you read it, we'd point you to two places for the current, authoritative position:

  • NHS Employers' own pre-employment check standards, which set out the national framework trusts generally work to
  • Your specific recruiting trust's occupational health team, who can tell you exactly what's required or recommended for the actual role and clinical setting you've been offered

If you don't know your own immunisation history, that's genuinely fine

Plenty of new starters don't have complete records of their own childhood or adult immunisation history to hand, and occupational health teams deal with this routinely — typically by arranging a blood test to check your actual immunity status directly, rather than relying purely on documentary history you may not have. If this applies to you, raise it with the occupational health team handling your assessment rather than worrying about it in advance.

What occupational health is actually trying to achieve — and what it isn't

It's worth being direct about this, because a lot of unnecessary anxiety around occupational health checks comes from a mistaken assumption about their purpose. Occupational health's role in NHS recruitment is generally to assess whether you can safely and effectively perform the specific duties of the role you've been offered — and, where there's a question mark over that, to consider whether reasonable adjustments would resolve it. It is not generally designed as a filter to look for reasons to withdraw a job offer.

This matters in practice for two common situations:

Disclosing a health condition or disability

Employers, including NHS trusts, operate under equality legislation that generally requires them to consider reasonable adjustments for a disclosed condition or disability, rather than simply rejecting a candidate on that basis. Declaring something honestly on an occupational health questionnaire is very often the start of a conversation about how the role can work for you — a phased start, adjusted duties, specific equipment — not an automatic barrier.

Disclosing mental health history

The same general principle applies to mental health information as to physical health information: the purpose is to assess fitness for role and consider adjustments, not to penalise disclosure. If you're anxious about how a specific disclosure will be handled, it's entirely reasonable to ask the occupational health team directly how they approach mental health information before you complete a declaration.

The honest approach is generally the better one

Declaring things accurately on an occupational health questionnaire — even something you're worried might count against you — is generally the better path than omitting it. An honest declaration lets occupational health do its actual job: working out whether, and how, you can do the role safely. An omission that later becomes relevant (for instance, if a condition affects your ability to perform a specific duty once you're in post) can create bigger problems than an honest disclosure would have, both practically and in terms of trust with your new employer.

How this fits alongside the other pre-employment checks

Occupational health clearance typically runs in parallel with other standard NHS pre-employment checks once you've accepted a job offer — most commonly a DBS check and, where relevant, right-to-work verification — rather than happening strictly before or after them. None of these processes are designed to catch you out; they're standard steps most new NHS starters go through, and delays in any one of them are a common, ordinary reason the gap between a job offer and an actual start date can run to several weeks. See our full how to join the NHS guide for how all of these pieces fit together.

Practical advice

  • Complete your health declaration honestly — the purpose is to assess fitness for role and identify adjustments, not to find reasons to reject you
  • Don't panic if you don't know your immunisation history — occupational health teams can typically check your immunity status directly rather than relying on records you don't have
  • Ask questions if you're unsure how something will be assessed — occupational health teams are used to fielding questions about specific conditions, disclosures or adjustments before you formally declare anything
  • Check NHS Employers' own pre-employment check standards if you want to understand the national framework behind the process, rather than relying only on secondhand descriptions
  • Respond promptly to requests for information or appointments, since occupational health is often one of several checks running in parallel and delays here can push back your start date

Why trust this guide

  • Explains the general purpose and structure of occupational health checks without inventing specific immunisation requirements we can't verify
  • Directly addresses the common, understandable anxiety around disclosing health conditions, rather than glossing over it
  • Points to NHS Employers' own pre-employment check standards as the authoritative national reference
  • Independent and not affiliated with the NHS, DHSC, or any individual trust's occupational health service

The bottom line

An occupational health check is a standard, sensible part of NHS pre-employment screening, built around assessing whether you can safely do the specific role you've been offered and identifying any adjustments that would help — not around finding reasons to reject you. Be honest on your declaration, don't panic over gaps in your immunisation history, and ask questions if you're unsure how something will be handled. For the current, authoritative national standards behind the process, see NHS Employers' own pre-employment check guidance rather than relying on general descriptions like this one for anything role-specific.

Frequently asked questions

Will an occupational health check reject me for having a health condition or disability? +

Generally, no — the purpose of the assessment is to establish fitness for the specific duties of the role and to identify whether reasonable adjustments would let you do the job safely and effectively, not to screen out candidates because they disclose a condition. Employers, including NHS trusts, have legal obligations under equality legislation to consider reasonable adjustments rather than simply rejecting a candidate because they've disclosed a health condition or disability. If you're unsure how a specific condition might be assessed, it's reasonable to ask the occupational health team directly rather than assuming the worst.

What immunisations will I actually need for my NHS role? +

It depends on the specific role, the clinical setting, and current guidance, which is exactly why we haven't listed specific immunisations on this page — requirements can vary and change over time. Your recruiting trust's occupational health team will tell you exactly what's required or recommended for your specific post, and NHS Employers' own pre-employment check standards are the authoritative national reference for how immunisation and screening requirements are generally structured.

Do non-clinical NHS roles need an occupational health check too? +

Often yes, though generally a less extensive one than a clinical, patient-facing role would require. Even roles without direct patient contact can involve physical demands (manual handling, shift patterns, specific working environments) that occupational health needs to assess fitness against. The depth and focus of the assessment is generally tailored to the actual demands of the role rather than being identical for every NHS job.

What happens if occupational health identifies a problem — does that mean I lose the job offer? +

Not automatically. Occupational health's role is generally to work out whether you can do the specific duties of the role safely, with or without reasonable adjustments — not to look for reasons to withdraw an offer. In many cases, an issue identified at this stage leads to a conversation about adjustments (equipment, altered duties, a phased start) rather than a rejection. Genuine cases where a role's core physical or clinical demands can't be safely met do exist, but they're generally the exception addressed through a considered process, not an automatic outcome.

Can I be honest about my mental health on an occupational health declaration without it damaging my chances? +

In principle, yes, and honesty is generally the better approach — occupational health assessments exist partly to identify support or adjustments that help someone do a role well, not just to flag risk. A well-run occupational health process treats a mental health disclosure the same way it treats a physical one: assessing fitness for the specific role and considering reasonable adjustments. If you're anxious about how a disclosure will be received, it's reasonable to ask the occupational health team how they handle mental health information before you complete a declaration, rather than assuming disclosure is automatically risky.

Is occupational health information shared with my new manager or the wider recruitment team? +

Occupational health operates under standard medical confidentiality principles, generally sharing only a fitness-for-role outcome and any recommended adjustments with the recruiting manager or HR — not the detailed clinical information behind that outcome. Exact information-sharing practices can vary by trust and by the sensitivity of what's involved, so if you have specific concerns about confidentiality, it's reasonable to ask the occupational health team directly how information about your case will be shared before you complete a declaration.

Does the occupational health check happen before or after the DBS check? +

There's no single fixed national order — many trusts run pre-employment checks, including DBS, occupational health and reference checks, broadly in parallel once an offer has been made, rather than in a strict sequence. See our <a href="/careers/nhs-dbs-check-explained/">DBS check guide</a> for how that specific check works alongside this one.

Do I need a fresh occupational health check every time I move to a new NHS trust? +

Generally yes, in most cases, since occupational health clearance is typically tied to the specific role and trust you're joining rather than being a portable, one-off certificate like a DBS check can potentially become via the Update Service. Some information (such as immunisation history) may transfer more easily between trusts if properly documented, but confirm with the specific trust's occupational health team what they require from you as a new starter.

What if I don't know my own immunisation history? +

This is a genuinely common situation, and occupational health teams are used to dealing with it — they can typically arrange blood tests to check your immunity status directly, rather than relying solely on documentary history, and advise on any immunisations or boosters needed based on the result. Don't assume a gap in your own records is a barrier; raise it with the occupational health team handling your assessment.

Where can I find the authoritative, current standards for NHS pre-employment health checks? +

NHS Employers publishes national guidance on pre-employment check standards, including the general framework trusts use for health clearance, and this is the right place to look for the current, authoritative version rather than relying on a general guide like this one. Specific immunisation and screening requirements are also subject to UK Health Security Agency and Department of Health and Social Care guidance, which is reviewed and can change.
