Frozen Shoulder Sick Note: UK Sickness Rules and Adjustments

Frozen shoulder can justify sickness evidence when symptoms prevent your normal work. Explain the tasks affected, treatment and any useful adjustments. A diagnosis does not automatically mean you need a paid certificate, and the first seven calendar days can normally be self-certified.

This detailed clinical and statutory guide outlines the process of securing a fit note for frozen shoulder in the UK, understanding your rights regarding workplace adjustments, and managing sickness absence. If you need a professional medical certificate to support your recovery or to present to your employer, you can learn more about our private medical certificate service or submit an online consultation request directly on our secure portal. Our medical team reviews submissions promptly, ensuring you receive the compliant medical evidence required to protect your rights and focus on rehabilitation.

The Pathophysiology and Clinical Phases of Frozen Shoulder

The shoulder joint is a ball-and-socket joint surrounded by a strong, flexible tissue capsule. Adhesive capsulitis occurs when this shoulder capsule becomes severely inflamed, thickens, and tightens, leading to the development of bands of scar tissue called adhesions. This process reduces the volume of the joint cavity and restricts the lubrication within the joint, making movement extremely painful and physically restricted. While the exact cause is not always clear, risk factors include diabetes, thyroid disorders, cardiovascular disease, and prolonged immobility of the shoulder following a stroke, mastectomy, or shoulder injury.

Frozen shoulder typically progresses through three distinct clinical phases, each presenting unique challenges for the patient. The first phase is the freezing or painful phase, which lasts from two to nine months. During this time, pain develops gradually, often worsening at night or when lying on the affected side, and the shoulder begins to lose range of motion. The second phase is the frozen or adhesive phase, lasting from four to twelve months. In this phase, the pain may start to diminish, but the shoulder becomes extremely stiff, making everyday activities like dressing, reaching, or driving almost impossible. The third phase is the thawing or resolution phase, which can take between five months and three years, during which the shoulder's range of motion slowly improves.

Managing a frozen shoulder requires a combination of pain management, physical therapy, and joint preservation. Clinical treatments can include non-steroidal anti-inflammatory drugs (NSAIDs), intra-articular corticosteroid injections to reduce inflammation, and joint mobilization exercises. In severe, resistant cases, surgical interventions such as manipulation under anesthesia (MUA) or arthroscopic capsular release may be necessary. If you are recovering from surgery or undergoing intensive physical therapy, a period of modified duties or complete rest is crucial. Continuing to strain the joint can worsen inflammation and prolong the recovery timeline, highlighting the importance of timely medical certification.

Sickness Absence Rules in the UK: Self-Certification and Fit Notes

Self-certification normally covers the first seven calendar days, including weekends. For a longer absence, discuss a fit note with the healthcare professional treating you and follow your employer's reporting policy. A private medical certificate is a different document from an NHS Med 3 fit note; check that your employer will accept it before paying. See GOV.UK sickness evidence guidance.

If your frozen shoulder symptoms prevent you from working for more than seven consecutive calendar days, you must provide your employer with a fit note, officially called a Statement of Fitness for Work. This seven-day threshold includes all calendar days, including weekends and public holidays. To ensure there is no gap in your sickness documentation, you should arrange a clinical assessment around the eighth day of your absence. If you experience difficulty booking an appointment with your GP, you can submit an online sick note consultation to request a clinical review by a GMC-registered doctor on our secure portal.

A clinician can consider earlier dates when the history and evidence support them. Backdating or a particular certificate duration is not guaranteed. Tell your employer if documentation is delayed and keep them informed about the expected assessment.

Obtaining a Fit Note for Frozen Shoulder

Securing a fit note for a frozen shoulder requires a clinical evaluation by a registered healthcare professional. In the UK, fit notes can be issued by doctors, nurses, occupational therapists, pharmacists, and physiotherapists. During your assessment, the clinician will discuss your symptoms, evaluate your joint range of motion, and assess how the stiffness affects your ability to perform your specific job duties. If your work involves manual labor, overhead reaching, heavy lifting, or prolonged keyboard use, you must explain these physical demands to the clinician.

To support your request for a fit note, you should present any relevant medical documentation, such as letters from a physiotherapist, details of corticosteroid injections, or records of orthopedic consultations. The clinician will evaluate this information to determine if you are "not fit for work" or if you "may be fit for work" under specific conditions. For chronic conditions like adhesive capsulitis, the duration of the fit note is typically set for several weeks or months to allow time for physical therapy or other interventions to take effect.

Discuss the advice on your fit note with your employer and explain any safety concerns. Adjustments and fitness for your specific duties need an individual discussion. Seek advice from your treating clinician, occupational health or Acas if there is a dispute.

Workplace Adjustments and the Equality Act 2010

Under the Equality Act 2010, a frozen shoulder can be legally recognized as a disability if it has a substantial and long-term adverse effect on your ability to carry out normal day-to-day activities. In this context, "long-term" means the condition has lasted, or is expected to last, for at least twelve months. If your frozen shoulder meets this statutory definition, your employer is legally required to make reasonable adjustments to help you overcome the disadvantages caused by your condition at work and support your return to duties.

Reasonable adjustments for a frozen shoulder are tailored to your specific physical limitations. Common adjustments include providing ergonomic office equipment, such as split keyboards, a vertical mouse, a document holder, and voice-to-text software to reduce arm movement. For physical roles, adjustments can include restricting overhead reaching, avoiding heavy lifting, and reassigning manual tasks to colleagues. Logistical adjustments can include flexible working hours to allow attendance at physiotherapy sessions and permitting home working to eliminate painful commutes.

If your fit note indicates that you "may be fit for work" with adjustments, you must discuss these recommendations with your employer. If your employer is unable or unwilling to implement the recommended adjustments, the fit note must be treated as "not fit for work," and you should remain on sick leave. To learn how to manage a return to work after an extended absence, read our guide on a phased return to work for structured return patterns.

Statutory Sick Pay and Financial Support

For sickness from 6 April 2026, eligible workers receive SSP from their first full qualifying day. The lower earnings limit and three waiting days have been removed. The ordinary 2026/27 weekly amount is the lower of £123.25 or 80% of average weekly earnings, for up to 28 weeks. Other eligibility rules and transitional protection can apply. See Acas SSP guidance.

Company sick pay may provide more than SSP under your contract. Check the reporting requirements and any evidence requested for enhanced pay. The old SSP waiting days no longer apply to new sickness from 6 April 2026.

If your sick leave extends beyond 28 weeks and your SSP entitlement is exhausted, or if you do not qualify for SSP in the first place, your employer must provide you with form SSP1. This form allows you to apply for state benefits, such as Employment and Support Allowance (ESA) or Universal Credit, through the Department for Work and Pensions (DWP). Securing continuous medical evidence through fit notes is vital during this transition, as the DWP will require ongoing proof of your incapacity to work to process your claims. If your employer refuses to accept your sick note, read our guide on what to do if your employer refuses a sick note for detailed advice.

How DoctorCert Can Help with Your Sickness Documentation

DoctorCert offers a remote review for a private medical certificate. Issuance and the dates supported depend on the doctor's assessment and available evidence. This does not guarantee sick pay, employer acceptance or protection from dismissal. Check the work sick note service and your employer's requirements before booking. Urgent symptoms need medical care, not a certificate application.

Our service supports your sickness absence management with these key features:

The doctor reviews your request and supporting evidence and decides whether a private certificate is appropriate. Employer verification confirms authenticity, not automatic entitlement to SSP or company sick pay.

Frequently Asked Questions

Can you get a sick note for frozen shoulder?

Yes. Frozen shoulder is a recognized medical condition that causes severe pain and stiffness, restricting functional movement. If a clinician determines that your shoulder symptoms prevent you from performing your work, they can issue a fit note.

How long can you be signed off work with frozen shoulder?

There is no standard number of days off for this condition. A clinician considers your symptoms, treatment and actual duties, and reviews the duration when needed. A desk role with adjustments may be manageable before lifting, driving or other demanding work is safe.

Is frozen shoulder considered a disability under the Equality Act?

Yes, if the condition has lasted or is expected to last for twelve months or more, and has a substantial adverse effect on your ability to perform normal day-to-day activities, it meets the statutory definition of a disability.

Can I work with a frozen shoulder?

Yes, depending on your job duties and the severity of your symptoms. If your job involves desk work and your employer implements adjustments (such as ergonomic keyboards or voice-to-text software), you may be able to continue working safely.

What happens if my employer cannot accommodate the adjustments on my fit note?

If your employer cannot implement the adjustments recommended on your fit note (such as avoiding overhead reaching), the fit note is treated as "not fit for work," and you should remain on sick leave.

Preparing for a work discussion

Describe reaching, lifting, dressing and commuting difficulties. Ask about temporary tasks that avoid painful movements and breaks for the treatment plan recommended by your clinician. The NHS frozen shoulder guide explains treatment and when to seek help.
