Occupational health providers give employers independent advice on fitness for work, adjustments, health surveillance and safety critical medicals. Compare them on the services offered, accreditation and how quickly they can see your staff. The deciding factor is which services you need and whether the provider is accredited for those exact services. Ten options follow in no particular order.
Occupational health is where HR goes when a health question gets too big for a manager. Someone's been off for months, a new starter needs a medical, or a role involves noise, dust or vibration that the law says you must monitor. A good provider turns those situations into clear, practical advice.
The ten providers below range from national groups to regional specialists. They're listed alphabetically and in no particular order, and every description comes from the provider's own website, read this week. This page describes services and accreditation only. It isn't medical advice, and individual health questions belong with a clinician. My guide to improving employee wellbeing covers the everyday side.
Occupational health providers compared
The last column shows whether the page I read on each provider's own website names SEQOHS, as of Oct 2026. Not stated doesn't mean they can't offer it. It means that page didn't say so, so ask before you sign anything.

Check the SEQOHS certificate, not just the list
The TUC says some occupational health providers are only accredited for certain parts of the SEQOHS standard, so you should always check the certificate to see what they're accredited to do, not just whether they're on the list.

SEQOHS is the accreditation scheme for occupational health services. It's a good sign, but it isn't all or nothing. A provider can hold accreditation for clinical services and not for, say, physiotherapy or a particular kind of medical. Before you sign, ask for the certificate and match it against the services you're buying, then keep a copy with the contract.
National group, regional provider or one-off support?
National groups suit employers with sites across the country. They offer one contract, one reporting system and clinics in many places, and they're used to high volumes of referrals.
Regional providers often know local employers well and can be quicker to respond. They suit firms in one area that want the same clinicians each time.
One-off support suits small employers with an occasional case. You get advice when you need it, without a long contract you'll rarely use.
Seven questions to ask an occupational health provider
- Which services does your SEQOHS certificate cover?
- How quickly will a management referral be seen?
- Will we get reports a manager can act on?
- Do you offer remote and face to face appointments?
- Which health surveillance can you deliver on our sites?
- Who are the clinicians, and what are their qualifications?
- How will you share information while protecting employee confidentiality?
Signs you need occupational health support
- A long absence has no plan. Nobody knows when or how they'll return.
- Managers guess at adjustments. They need clinical advice.
- Roles carry noise, dust or vibration. Surveillance may be required.
- New starters need medicals. Safety critical jobs demand them.
Do you offer occupational health services? Providers can ask to be considered for a featured place on this list.
My plain advice on choosing occupational health
Write down the three situations you face most often before you speak to anyone. Long-term sickness, pre-placement medicals and noise or dust surveillance need very different services, and providers are stronger at some than others. Ask each one how they'd handle your three situations, and judge them on how practical the answer is for your managers.
If you don't have an HR team to manage the provider, my guide to UK HR support services shows who can help.
Frequently asked questions
What does an occupational health provider do?
It gives employers independent advice on employees' fitness for work, adjustments, health surveillance and work-related medicals.
What is SEQOHS?
SEQOHS is the accreditation scheme for occupational health services in the UK. Check what each provider's certificate covers.
Can a provider be accredited for only some services?
Yes. The TUC says some providers are accredited for certain parts of the standard only, so check the certificate.
Do small businesses need occupational health?
Not always on a contract. Many small employers buy one-off advice when a long absence or a medical question comes up.
Is occupational health advice confidential?
Occupational health clinicians follow confidentiality rules. Ask each provider how they share reports with managers.
Is this page medical advice?
No. It describes providers' services and accreditation. Individual health questions should go to a qualified clinician.
