What Is a Work Adjustment Medical Certificate?
A work adjustment medical certificate — also known as an adjustments to work duties letter — is a medical document from a GMC-registered doctor outlining recommended modifications to your work responsibilities based on your health condition. It communicates to your employer what changes are needed to allow you to work safely and effectively while recovering from illness or managing an ongoing condition.
What it does
Unlike a sick note, which certifies that you are unable to work, a work adjustment certificate confirms that you can continue working — subject to specific modifications. It bridges the gap between full sick leave and normal duties, enabling a graduated return or an adjusted working arrangement that protects your health.
This mirrors the “may be fit for work” assessment on an NHS Fit Note, but in a more detailed, standalone format appropriate for private documentation of specific adjustment recommendations.
Sick Note vs Work Adjustment Certificate — Which Do You Need?
🔧 Work Adjustment Certificate
- ✔ You can work but need modifications to your duties or environment
- ✔ Supporting a phased return after sick leave
- ✔ Managing a chronic condition while remaining employed
- ✔ Formally documenting a reasonable adjustment request
- ✔ Returning early before a sick note expires with conditions
📋 Sick Note (Fit Note)
- ✔ You are unable to work in any capacity
- ✔ Absence for 8 or more consecutive calendar days
- ✔ Certifying absence to access Statutory Sick Pay
- ✔ Short-term acute illness preventing any attendance
If you are currently on stress leave or recovering from an illness and want to return to work in a modified capacity, a work adjustment certificate is the appropriate document. If you need to certify full absence, see our fit to work certificate for clearance when returning after sick leave.
Common Work Adjustments Covered
Our doctors can recommend a wide range of modifications where clinically appropriate. Adjustments are tailored to your specific condition and role. Certificates are suitable for low-risk, non-hazardous workplaces — high-risk environments (plant operators, scaffolding, road work) require specialist occupational health assessments.
Reduced working hoursPart-time or reduced hours during recovery, increasing progressively.
Remote or home workingWhere role permits, working from home to reduce commute fatigue or physical demands.
Modified dutiesTemporary removal from tasks that aggravate your condition — manual handling, sustained standing, client-facing roles.
Ergonomic or physical modificationsRecommendations for adapted equipment, adjusted workstations, or physical access provisions.
Phased return to full dutiesA graduated plan from light duties back to full responsibilities.
Flexible start or finish timesAdjusted patterns to accommodate medication schedules, fatigue cycles, or treatment appointments.
Reduced targets or workloadTemporary reduction in performance targets or volume of work during recovery.
Time off for medical appointmentsAcknowledgement of ongoing treatment needs and support for appointment attendance.
Conditions Commonly Supported by a Work Adjustment Certificate
Adjustments can be appropriate for both physical and mental health conditions — subject to clinical assessment. Common presentations include:
The Legal Framework — Reasonable Adjustments and the Equality Act 2010
What the law requires
Under the Equality Act 2010, employers have a legal duty to make reasonable adjustments for employees with disabilities — defined as physical or mental impairments with a substantial, long-term adverse effect on normal day-to-day activities. This duty is triggered when the employer becomes aware (or should reasonably be aware) of a condition placing the employee at a substantial disadvantage.
A work adjustment certificate from a GMC-registered doctor provides the medical evidence that both supports your request and puts your employer on notice of your clinical needs. Where an employer fails to make reasonable adjustments despite medical evidence of need, this may constitute disability discrimination under the Act.
Not all conditions requiring adjustments meet the legal disability threshold — shorter-term or lower-impact conditions may still warrant adjustments as good practice. Many employers accommodate adjustment requests without requiring formal legal justification.
For formal disputes, ACAS offers free guidance and early conciliation services. Access to Work grants are also available through DWP for assessments and equipment costs linked to disability at work.
How to Get a Work Adjustment Medical Certificate
Complete a medical questionnaire
Describe your health condition, how it affects your ability to perform your current duties, and what specific adjustments you are seeking. Include your job role and working environment — the more specific you are, the more tailored your certificate will be.
Upload supporting evidence
A brief video describing your symptoms and working situation, or supporting documentation such as a prescription, previous GP letter, or hospital discharge notes. Evidence of your condition helps the doctor make well-informed recommendations.
GMC-registered doctor reviews and issues your certificate
One of our experienced GPs reviews your submission the same day and — where clinically appropriate — issues a certificate specifying recommended work adjustments. The certificate will detail your condition, the adjustments recommended, and their expected duration.
Deliver to your employer and agree a plan
Your certificate is delivered by email same day or by 9AM next morning as a signed PDF. Present it to your employer or HR department as the basis for a return-to-work or ongoing adjustment discussion. Each certificate includes a unique reference number verifiable at verify@medicalcert.co.uk.
