Altered or copied documents do not pass that check.
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 without a GP appointment, with most approved same day or by 9AM next morning. Employers decide what evidence they accept, and a private certificate is commonly used as evidence for sickness absence and Statutory Sick Pay (SSP) records.
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 documents your absence for your employer, though whether you get SSP depends on your employment and earnings rather than on the note itself. 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. NHS guidance says symptoms of tonsillitis usually go away after 3 to 4 days but can last longer. Longer again 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 can be very different. NICE guideline NG84 notes that acute sore throat, including tonsillitis, is self-limiting, that most people get better within around a week whether the cause is bacterial or viral, and that antibiotics shorten symptoms by about 16 hours on average. Glandular fever can take weeks. Knowing which you have often needs a swab or blood test. NHS guidance on tonsillitis says to see a GP if symptoms do not go away within 1 week or if you keep getting throat infections, and to get help from NHS 111 straight away if you have pus-filled spots on your tonsils or a sore throat so painful it is difficult to eat or drink.
Most issued same day or by 9AM next morning. 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 taking sick leave says an employee must give their employer a fit note if they have been ill for more than 7 days in a row, counting non-working days such as weekends and bank holidays.
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 ask for a sick note even for a 2 or 3-day absence. This is a public-health and duty-of-care position, not a punishment. Acas advises the opposite as the default position: an employer should only ask for a fit note from the seventh day of absence, and someone off for 7 calendar days or less does not need to provide medical evidence. Where an employer does ask for something earlier, GOV.UK's guide for employers is clear that the employer decides what is acceptable, and that if the employer agrees, the employee can give another appropriate form of evidence instead. Check your absence policy or ask HR before you order.
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. Antibiotics are prescribed only where clinically indicated.
Return to work: where antibiotics have been prescribed, the commonly used return point is at least 24 hours after the first dose, fever-free for 24 hours, and well enough to function.
Viral tonsillitis
Most cases. Caused by common viruses including adenovirus, rhinovirus and Epstein-Barr virus. Antibiotics do not treat a virus. Treatment is rest, fluids, paracetamol or ibuprofen.
Return to work: when symptoms clearly resolve, usually after 3 to 4 days but sometimes longer. 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 only where clinically indicated. NICE guideline NG84 gives phenoxymethylpenicillin for 5 to 10 days as first choice, with clarithromycin, or erythromycin in pregnancy, where there is penicillin allergy. Amoxicillin is not among the options NICE recommends | Rest, fluids, avoid contact sports (spleen risk) |
| Time off work | Usually 3 to 4 days, sometimes longer | 24 hours after starting antibiotics, then back when fever-free | 2 to 4 weeks, sometimes longer |
| Contagious period | Until symptoms resolve | Around 2 to 3 weeks untreated. NHS advice is to stay at home and avoid contact with other people until you feel better. Where antibiotics are given, 24 hours after the first dose is the commonly used return point | 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 says to see a GP if tonsillitis symptoms have not gone within 1 week, and that a blood test for glandular fever may be needed if symptoms are severe or will not go away. 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. NHS guidance says to call 999 or go to A&E for these signs, and not to drive yourself. 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. Whether tonsillectomy is appropriate is a decision for your GP and an ENT specialist, not something that can be settled online. NHS guidance says it is very rare for someone to need their tonsils taken out, and that this is usually only done where severe tonsillitis keeps coming back.
When to ask your GP about ENT referral
Referral thresholds are set locally and turn on how many documented episodes you have had over the preceding one to three years and how severe each one was. Your GP applies the criteria your local NHS commissioners use. What helps either way is a dated record of every episode, which forms part of the evidence an ENT specialist will want to see.
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 commonly takes around two weeks and needs a separate post-operative certificate. Your surgical team will advise on how much time off your own recovery needs.
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. Acas says an employer must keep information about a worker's health confidential and manage it in line with UK GDPR, and that an employer needs the worker's permission before asking a doctor for a report about their health.
