Sick note for work — professional and fast
My GP had a 3-week wait. MedicalCert issued a sick note within a few hours. The doctor was thorough, and my employer accepted it without question. Exactly what I needed.
Sick Note for Tonsillitis
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 Statutory Sick Pay, 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.
Same day. Full refund if a doctor cannot issue.
When You Need a Sick Note for Tonsillitis
Under UK 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. 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 satisfies it the same way an NHS one does.
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. Treated with a 5 to 10 day course of penicillin or amoxicillin.
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.
Tonsillitis (viral)
Sore throat, swollen tonsils, low to moderate fever, often part of a cold or flu-like illness.
Off work: 3 to 5 days typical.
Strep throat (bacterial)
Severe sore throat, high fever, white or yellow tonsil patches, swollen lymph nodes, often no cough.
Off work: 24 hours after starting antibiotics, then back when fever-free.
Glandular fever
Severe persistent sore throat, profound fatigue, swollen lymph nodes throughout the neck, sometimes splenic enlargement.
Off work: 2 to 4 weeks, sometimes longer.
The clinical reality: we cannot diagnose Epstein-Barr virus 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 for monospot or EBV serology. 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. Current rate is £123.25 per week or 80% of your average weekly earnings, whichever is lower.
Many employers offer contractual sick pay above the statutory minimum. Check your contract.
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. UK clinical guidance, including SIGN, considers tonsillectomy referral when episodes are frequent and disrupting normal life.
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. No automated approvals, no offshore review. 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.
