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.
Sick Note for Tonsillitis
Yes, you can get a sick note for tonsillitis online in the UK. A GMC-registered doctor reviews your online consultation and issues a signed certificate same day, without a GP appointment. The certificate is accepted by UK employers as evidence for sickness absence and Statutory Sick Pay (SSP).
Tonsillitis is one of the few conditions where staying home is not just about how you feel. It is about whether you are still contagious to colleagues, customers and family. A signed sick note from MedicalCert confirms your absence to your employer and qualifies you for SSP, but the bigger question for most people is the simpler one: when can I safely go back to work?
How long off work for tonsillitis: the short answer
Bacterial tonsillitis (including strep throat): stay off work until you have been on appropriate antibiotics for at least 24 hours and have been fever-free for 24 hours.
Viral tonsillitis: stay off until your symptoms have clearly resolved, typically 3 to 5 days from symptom onset. Longer if the cause is glandular fever (Epstein-Barr virus), which can mean 2 to 4 weeks.
Tonsillitis, strep throat or glandular fever?
All three present with severe sore throat and swollen tonsils, but the time off work is very different. Strep throat clears quickly with antibiotics. Viral tonsillitis usually resolves in under a week. Glandular fever can take weeks. Knowing which you have changes the answer to "when can I return?", and that often needs a swab or blood test. NHS guidance on tonsillitis (nhs.uk/conditions/tonsillitis) recommends seeing a GP if symptoms last longer than four days or are severe.
Same day. Full refund if a doctor cannot issue.
When You Need a Sick Note for Tonsillitis
Under UK employment law you can self-certify the first seven calendar days of any sickness absence. From day eight, your employer can request medical evidence before paying SSP or processing your absence record. GOV.UK guidance on employee sick leave (gov.uk/taking-sick-leave) confirms that a fit note or equivalent medical evidence is required from day eight onwards.
Tonsillitis sits in an unusual position because it is often resolved within the seven-day window, yet many employers still want a sick note for shorter absences when the role involves close contact with the public.
If you work in hospitality, healthcare, education, food preparation, customer-facing retail or any role that brings you within droplet range of colleagues or customers, your employer or your contract may require a sick note even for a 2 or 3-day absence. This is a public-health and duty-of-care position, not a punishment, and a private medical certificate from a GMC-registered doctor satisfies it the same way an NHS one does. ACAS guidance on managing staff absence treats medical evidence from any registered doctor as valid.
For absences extending beyond seven days, a sick note becomes a legal requirement for SSP. If your tonsillitis is recurring or your GP suspects glandular fever and you are looking at two weeks or more off, get the certificate dated from the start of your absence.
How Long Off Work for Tonsillitis: The Contagion Rules
Tonsillitis itself is not contagious, but the viruses and bacteria that cause it are highly contagious. The return-to-work answer depends entirely on which type you have.
Bacterial tonsillitis
Most often caused by Group A Streptococcus, the same bacterium responsible for strep throat. If bacterial tonsillitis is suspected, a doctor may prescribe antibiotics where clinically appropriate.
Return to work: at least 24 hours after starting antibiotics, fever-free for 24 hours, and feeling well enough to function. Bacterial load drops sharply once antibiotics are working.
Viral tonsillitis
Most cases. Caused by common viruses including adenovirus, rhinovirus and Epstein-Barr virus. Antibiotics do nothing here. Treatment is rest, fluids, paracetamol or ibuprofen.
Return to work: when symptoms clearly resolve. Typically 3 to 5 days. You remain mildly contagious until symptoms are gone, so wait until fever and severe sore throat have settled.
Without a throat swab, telling viral from bacterial in a remote consultation is an informed clinical judgement based on the symptom picture. The reviewing doctor will issue based on what is in front of them and the likely time-off range. If symptoms persist beyond what was expected, request a follow-up.
Tonsillitis vs Strep Throat vs Glandular Fever
These three conditions overlap heavily on symptoms and confuse a lot of people, including some employers. The time off work answer is genuinely different for each.
| Viral tonsillitis | Strep throat (bacterial) | Glandular fever (EBV) | |
|---|---|---|---|
| Typical symptoms | Sore throat, swollen tonsils, low to moderate fever, often with cold symptoms | Severe sore throat, high fever, white or yellow tonsil patches, swollen lymph nodes, usually no cough | Severe persistent sore throat, profound fatigue, widespread lymph node swelling, sometimes splenic enlargement |
| Cause | Adenovirus, rhinovirus, other common viruses | Group A Streptococcus | Epstein-Barr virus |
| Treatment | Rest, fluids, paracetamol or ibuprofen | Antibiotics (penicillin or amoxicillin, 5 to 10 days) | Rest, fluids, avoid contact sports (spleen risk) |
| Time off work | 3 to 5 days | 24 hours after starting antibiotics, then back when fever-free | 2 to 4 weeks, sometimes longer |
| Contagious period | Until symptoms resolve | Up to 2 weeks untreated; 24 to 48 hours on antibiotics | Several weeks (virus shed in saliva for months) |
| Diagnosis confirmation | Clinical assessment | Throat swab (rapid strep test) | Blood test (monospot or EBV serology via GP) |
The clinical reality: Epstein-Barr virus cannot be diagnosed remotely. If your sore throat lasts beyond 7 to 10 days with worsening fatigue, lymph node swelling and a feeling of being properly unwell rather than just throaty, you need a GP appointment and a blood test. NHS guidance recommends urgent GP review if tonsillitis symptoms persist beyond four days without improvement. We will tell you if your consultation suggests this pattern and recommend you see your GP for further assessment.
Symptoms That Justify a Sick Note for Tonsillitis
Our doctors look for a symptom cluster consistent with active tonsillitis. You do not need every symptom listed. A combination indicating significant inflammation, contagion risk and inability to work safely supports issuance.
Severe sore throat
Pain on swallowing, often radiating to the ears, that interferes with eating, drinking and talking.
Fever and chills
Temperature of 38°C or higher, often with sweats, body aches and fatigue.
White or yellow tonsil patches
Visible exudate on the tonsils, often a strong indicator of bacterial infection. A photograph during consultation helps the reviewing doctor.
Swollen, tender lymph nodes
Particularly in the neck and under the jaw. Indicates the immune system is actively responding.
Difficulty swallowing
Reduced ability to manage food, fluids or saliva. Combined with fever, makes work attendance impractical and risks dehydration.
Marked fatigue
Particularly characteristic of viral tonsillitis and a red flag for glandular fever if pronounced and persistent.
Symptoms that need A&E, not a sick note
Difficulty breathing, audible noisy breathing, drooling because you cannot swallow saliva, severe one-sided neck swelling or a muffled "hot potato" voice can indicate peritonsillar abscess (quinsy) or airway compromise. Call 111 or attend your nearest A&E. These cases need urgent assessment and possibly drainage, which is beyond what a private certificate service can safely address. We refund any consultation we cannot complete on clinical grounds.
Sick Pay and SSP for Tonsillitis
Tonsillitis qualifies for Statutory Sick Pay on the same basis as any other sickness absence. The April 2026 SSP changes matter here because tonsillitis is often a 3 to 5 day absence, exactly the length that previously fell into the unpaid waiting period.
SSP is now payable from day one of absence. The previous three waiting days have been abolished, so a typical 4-day tonsillitis absence is now fully paid where it would once have been mostly unpaid. The lower earnings limit has also been removed, so part-time workers, zero-hours contract workers and lower earners who previously did not qualify now do. The current rate is £123.25 per week or 80% of your average weekly earnings, whichever is lower (GOV.UK, Statutory Sick Pay).
Many employers offer contractual sick pay above the statutory minimum. Check your contract or staff handbook.
Recurrent Tonsillitis and Repeat Sick Notes
If you get tonsillitis multiple times a year, you are not alone and you are not unreasonable for needing repeat sick notes. The Scottish Intercollegiate Guidelines Network (SIGN guideline 117, Management of sore throat and indications for tonsillectomy) provides the standard UK clinical criteria for tonsillectomy referral.
When to ask your GP about ENT referral
The widely-used referral threshold is 7 or more documented episodes in the preceding year, 5 per year for the previous two years, or 3 per year for the previous three years, where each episode was severe enough to interfere with normal activities. Documented sick notes from each episode form part of the evidence trail an ENT specialist will want to see at referral.
Repeat MedicalCert certificates contribute to that record. Each one carries a date, doctor name, GMC registration number and the issuing clinical reasoning. Keep them. If you do progress to tonsillectomy, recovery typically requires 10 to 14 days off work and a separate post-operative sick note.
What Is on Your MedicalCert Tonsillitis Sick Note
Every certificate is reviewed and signed by a GMC-registered UK doctor. The document your employer receives contains:
Certificate contents
- Your full name and date of birth
- The dates you are certified as unfit for work
- The condition referenced as tonsillitis or acute pharyngotonsillitis, included only with your explicit consent
- Any recommended workplace considerations (e.g. avoidance of public-facing duties for the contagious period)
- The issuing doctor's full name, signature and GMC registration number
- Date of issue and clinic identifying details
- A statement that the certificate is issued by a UK GMC-registered doctor
If you would prefer the condition not be named, the certificate can simply state that you are unfit for work for the period specified. Your employer is not entitled to demand a diagnosis. ACAS guidance on handling medical information at work confirms that employees are not obliged to disclose the specific nature of their illness.
