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.
Yes, You Can Get a Sick Note for Sinusitis
You can get a sick note for sinusitis in the UK. Sinusitis is a recognised medical condition, and a GMC-registered doctor can certify your absence from work after assessing your symptoms. You do not need a specialist referral, a scan, or a hospital-confirmed diagnosis. NHS guidance confirms that sinusitis is diagnosed on clinical symptoms alone in almost all cases.
The facial pain, sinus pressure, blocked nasal passages, and fatigue caused by sinusitis can make it impossible to concentrate, sit at a screen, or communicate at work. If your employer needs medical documentation for your absence, MedicalCert can provide it the same day, entirely online.
Can I get a sick note for sinusitis?
Yes. Sinusitis is a valid reason for certified sick leave in the UK. A GMC-registered doctor reviews your online consultation, assesses your symptoms, and issues a signed private medical certificate covering your absence. Most certificates are approved same day or by 9AM next morning.
No waiting room, no appointment, no commute when you already have a pounding headache.
Why Sinusitis Can Warrant a Sick Note
Sinusitis, inflammation of the sinuses that usually follows a cold or upper respiratory infection, is commonly misunderstood as a minor condition. Acute sinusitis causes symptoms that can make sustained work genuinely impossible, particularly for roles involving concentration, communication, or screen use:
Chronic sinusitis, where symptoms persist for more than 12 weeks, can also be certifiable where it causes ongoing impairment of function. NICE Clinical Knowledge Summaries define chronic rhinosinusitis by this 12-week threshold. A doctor assesses what you can and cannot do, not just whether you have been formally diagnosed.
Acute vs chronic sinusitis: does it make a difference for a sick note?
Acute sinusitis has a sudden onset, typically follows a cold, and lasts up to 4 weeks. It is the most common presentation, and most sinusitis sick notes cover an acute episode. The certificate will typically say "acute sinusitis", "acute rhinosinusitis", or "upper respiratory tract infection with sinusitis".
Chronic sinusitis involves persistent symptoms lasting 12 weeks or more. It can be certified for longer periods where the ongoing impact on function is documented. If your sinusitis is chronic, note the duration and any treatment you have had when completing the consultation.
When Do You Need a Sick Note for Sinusitis?
The rules for sinusitis are the same as for any other illness. Under GOV.UK guidance on taking sick leave, you can self-certify for the first seven calendar days of absence. Simply inform your employer you are unwell, with no doctor's note required. From day eight onwards, your employer can request medical evidence of your illness.
Some employers have their own absence policies that require documentation earlier, particularly if you have had multiple short-term absences. ACAS guidance confirms employers may ask for medical evidence for absences under seven days, though they normally meet the cost. If your employer has asked for a note for a sinusitis absence of under seven days, a private certificate from MedicalCert is fully accepted.
What your sinusitis sick note includes
- ✔ Your full name, date of birth, and contact details
- ✔ Diagnosis, typically "acute sinusitis", "rhinosinusitis", or "upper respiratory tract infection"
- ✔ Certified period of absence with start and end date
- ✔ "Not fit for work" or "may be fit for work" assessment as appropriate
- ✔ GMC registration number of the signing doctor
- ✔ Unique QR code for employer verification
How Long Can You Be Signed Off for Sinusitis?
Most sinusitis sick notes cover 7 to 14 days. NHS guidance states that acute sinusitis usually clears within 2 to 3 weeks, and a certificate typically covers the period during which symptoms are severe enough to prevent work. If symptoms persist beyond the initial certificate period and you remain unfit, a new certificate can be issued to extend the cover.
| Presentation | Typical recovery | Typical certified period |
|---|---|---|
| Acute viral sinusitis | 2 to 3 weeks, usually self-resolving | 7 to 14 days |
| Acute bacterial sinusitis | 2 to 4 weeks, may require antibiotics | 7 to 14 days, extendable if unresolved |
| Chronic sinusitis (12+ weeks) | Ongoing, with acute flare-ups | Per episode, assessed individually |
| Post-surgical recovery (e.g. FESS) | 1 to 2 weeks before returning to most roles | 7 to 14 days, longer for physical roles |
For chronic sinusitis with recurrent acute flare-ups, certificates can cover individual episodes or longer periods depending on the clinical picture. Where sinusitis has required surgery, such as functional endoscopic sinus surgery (FESS), the post-operative recovery period can also be certified.
Sick pay: what you are entitled to
From 6 April 2026 under the Employment Rights Act 2025, Statutory Sick Pay (SSP) is payable from the first day of certified absence. The previous three-day waiting period has been abolished. SSP is paid at £123.25 per week or 80% of average weekly earnings, whichever is lower, and all employees now qualify regardless of income.
Your employer may offer enhanced contractual sick pay above SSP. Check your employment contract. SSP is the legal minimum.
