Very happy, I ordered my Medical Certificate in the early morning hours and before noon time of same day I had it on my inbox. Speedy service and they present the health condition precisely, get to the point.
They meet the incredibly fast turnaround stated (certificate/letter sent before 9am the following morning if the doctor feels that a letter/certificate is appropriate) which is incredibly quick and I am really grateful for the help provided!
Very easy and quick to get my certificate. And the certificate was approved from the specific company to travel with my dog. I will use them again. Well done.
Second time using this company and they are fabulous! Always great, fast, friendly service. Highly recommend!
This was my second time using Medical Cert, and once again the service was exceptionally quick and professional. Everything was handled efficiently, with clear communication throughout.
I found the service very straight forward and quick. Exactly what I needed to get my Padi medical form signed before our holiday. Thank you very much.
Process was easy and responses were quick. I would recommend their service.
Fast efficient service for medical certificates. I used the not fit to fly service and was provided with a certificate the next day, the price is very reasonable and enabled a flight credit refund with my airline. Would recommend and would use again if needed.
A fast and efficient service. It wasn't complicated and the Fit-to-fly note was accepted by the Airport without any further questions. Thank you.
Ideal for me, I am looking to get a certificate for some medical issues I have. So this is the perfect solution for me, uploading docs was easy and the forms very straightforward to fill in. Will definitely use them again. Many thanks.
Excellent service. Easy to use and certificate issued in less than 24 hours. £39 as opposed to the £150 my GP charges. Highly recommended.
Quick and reasonably pain-free. Received their standard certificate as well as my requested bespoke certificate, by email, by 9am the following morning. Both completed properly, signed and stamped as required. More expensive than my GP, but infinitely quicker and easier.
One of the best experiences. It's easy to get a GP note.
Excellent. My GP refuses to issue DWP MED 3 Fit Notes to students. MedicalCert were excellent and extremely helpful in providing a necessary certificate. Highly recommended.
You were amazing, you kept me updated and replied promptly to any queries I had. I thank you from the bottom of my heart.
They helped me, they were very professional and nice.
Very pleased. Quick service with very professional letter provided.
Great service, pretty straight forward and easy to use the website.
I was recommended Medical Cert by a friend and was so impressed with the service received. I would recommend using a laptop rather than a phone. Overall a fantastic and fast service.
What Is a Work Adjustment Medical Certificate?
A work adjustment medical certificate is a letter from a GMC-registered doctor recommending specific changes to your working duties, hours, or environment based on your health condition. It allows you to remain in work, or return to work sooner, with modifications that protect your recovery. Under the Equality Act 2010 (sections 20 and 21), UK employers have a legal duty to make reasonable adjustments for employees whose health conditions place them at a substantial disadvantage.
How it differs from a sick note
A sick note for work certifies that you are unable to work. A work adjustment certificate confirms that you can work, subject to specific modifications. It bridges the gap between full sick leave and normal duties, enabling a graduated return or adjusted arrangement that protects your health while keeping you employed.
This mirrors the "may be fit for work" option on an NHS Fit Note (formally the Statement of Fitness for Work), but provides more detailed, standalone documentation of specific adjustment recommendations from a private GP.
Work Adjustment Certificate vs Sick Note vs Fit to Work Certificate
Three documents serve different purposes when managing health at work. The table below shows when each applies.
| Document | Purpose | When you need it | Employer obligation |
|---|---|---|---|
| Work adjustment certificate | Recommends specific modifications to duties, hours, or environment | You can work but need changes to your role or conditions | Must consider adjustments; refusal without good reason may breach the Equality Act 2010 |
| Sick note (fit note) | Certifies you are unfit for work, or may be fit with conditions | Absent from work for 8+ consecutive calendar days; needed for Statutory Sick Pay | Must accept as valid medical evidence of absence |
| Fit to work certificate | Confirms you are medically cleared to return to full duties | Employer requires medical clearance before you resume work after sick leave | May require before allowing return, depending on company policy |
Some employees need more than one document. For example, a fit to work certificate to authorise your return after sick leave, plus an adjustment certificate specifying the conditions of that return. If you are currently on stress leave and want to return in a modified capacity, the adjustment certificate is the appropriate document.
When to Choose Each Document
Work Adjustment Certificate
- ✔ You can work but need modifications to duties or environment
- ✔ Supporting a phased return after sick leave
- ✔ Managing a chronic condition while remaining employed
- ✔ Formally documenting a reasonable adjustment request
- ✔ Returning early before a sick note expires, with conditions
Sick Note (Fit Note)
- ✔ You are unable to work in any capacity
- ✔ Absence for 8 or more consecutive calendar days
- ✔ Certifying absence to access Statutory Sick Pay
- ✔ Short-term acute illness preventing any attendance
Common Work Adjustments a Doctor Can Recommend
Adjustments are tailored to your specific condition and role. Our GMC-registered doctors can recommend a wide range of modifications where clinically appropriate. Certificates are suitable for low-risk, non-hazardous workplaces. High-risk environments such as construction sites, plant operation, or motorway work require specialist occupational health assessments.
Part-time or reduced hours during recovery, increasing progressively as your condition improves.
Where your role permits, working from home to reduce commute fatigue or physical demands.
Temporary removal from tasks that aggravate your condition, such as manual handling, sustained standing, or client-facing roles.
Recommendations for adapted equipment, adjusted workstations, or physical access provisions.
A graduated plan from light duties back to full responsibilities over a defined period. See also our phased return to work letter for dedicated phased return documentation.
Adjusted patterns to accommodate medication schedules, fatigue cycles, or treatment appointments.
Temporary reduction in performance targets or volume of work during recovery.
Acknowledgement of ongoing treatment needs and support for appointment attendance during working hours.
Conditions Commonly Supported by a Work Adjustment Certificate
Adjustments can be appropriate for both physical and mental health conditions, subject to clinical assessment by a GMC-registered doctor. Common presentations include:
Your Legal Rights: Reasonable Adjustments Under UK Law
What the Equality Act 2010 requires
Under sections 20 and 21 of the Equality Act 2010, employers have a legal duty to make reasonable adjustments for employees with disabilities. The Act defines disability as a physical or mental impairment with a substantial, long-term adverse effect on normal day-to-day activities ("long-term" meaning 12 months or more, or likely to last that long).
This duty is triggered when the employer knows, or should reasonably know, that an employee's condition places them at a substantial disadvantage compared to colleagues without the condition. A work adjustment certificate from a GMC-registered doctor provides the medical evidence that both supports your request and formally puts your employer on notice of your clinical needs.
Where an employer fails to make reasonable adjustments despite documented medical evidence, this may constitute disability discrimination under the Act. Employees can raise a grievance internally, seek free early conciliation through ACAS (Advisory, Conciliation and Arbitration Service), or bring a claim to an employment tribunal.
Not every condition requiring adjustments meets the legal disability threshold. Shorter-term or lower-impact conditions may still warrant adjustments as good workplace practice. Many employers accommodate adjustment requests voluntarily without requiring formal legal justification.
The Access to Work scheme, administered by the Department for Work and Pensions, can also provide grants covering workplace assessments and equipment costs for employees whose disability or health condition affects their ability to do their job. Applications are made directly through GOV.UK.
