Reasonable Adjustments: Complete UK Employer Guidance

The Legal Duty

The duty to make reasonable adjustments arises under the Equality Act 2010. It is the primary mechanism through which the Act ensures disabled people can access employment on equal terms.

The duty has three separate requirements (limbs):

1. Provision, criterion, or practice (PCP): Adjust or remove a working rule or practice that puts a disabled person at a substantial disadvantage compared to non-disabled people.
2. Physical feature: Remove, alter, or provide a reasonable means of avoiding a physical feature of the workplace that puts a disabled person at a substantial disadvantage.
3. Auxiliary aids: Provide an auxiliary aid or service (e.g., software, equipment, or a support worker) where its absence puts a disabled person at a substantial disadvantage.

When the Duty Arises

The duty arises when the employer knows, or could reasonably be expected to know, that:

• The employee has a disability, AND
• The employee is likely to be placed at a substantial disadvantage without adjustments

The employer does not need to be told formally. If a manager can reasonably infer a disability from visible symptoms, prolonged sickness absence, or the employee's own statements, the duty may already apply.

What Is "Reasonable"?

Reasonableness is assessed on a case-by-case basis. The EHRC Statutory Code of Practice identifies relevant factors:

• Effectiveness: How likely is the adjustment to remove the disadvantage?
• Practicability: Is it practical to make?
• Cost: What is the financial and other cost, taking into account available resources (including Access to Work grants)?
• Disruption: How disruptive will it be?
• Employer's resources: The size and resources of the organisation are relevant — larger employers are expected to do more
• Availability of financial/other assistance: Access to Work grants reduce the financial burden

Important: The duty is to make adjustments that are reasonable — not every possible adjustment, and not any adjustment the employee requests. The employer must weigh costs and benefits.

The Interactive Process

The EHRC recommends an interactive process — a genuine, open conversation between employer and employee to identify the most effective adjustments.

Step 1: Recognise the Trigger

Has the employee disclosed a disability? Has sickness absence or performance raised a question? Has OH referred the employee?

Step 2: Invite a Conversation

Do not wait for the employee to formally request an adjustment. Proactively invite them to discuss their needs:

> "I want to make sure you have everything you need to do your job well. Can we set some time aside to discuss how we can support you?"

Step 3: Gather Information

• Ask the employee what adjustments they think would help
• Consider occupational health advice (OH referral is appropriate for complex cases — note that OH advises the employer, it does not make decisions for the employer)
• Consult Access to Work if specialist equipment or support may be needed

Step 4: Agree Adjustments

Document the agreed adjustments in writing (the Workplace Adjustments Passport is an ideal vehicle). Be specific about:

• What the adjustment is
• How long it will be in place
• Review date

Step 5: Review

Schedule a review. Adjustments should be reviewed (not removed) at agreed intervals. A review is an opportunity to assess what is working and make changes.

When the Employer Can Decline

An employer can decline to make an adjustment if it is not reasonable. Factors that may make an adjustment unreasonable:

• Prohibitive cost relative to employer size (though Access to Work may remove this argument)
• Adjustment would fundamentally alter the nature of the role
• Adjustment is impractical given the physical environment

However: The employer bears the burden of showing an adjustment is unreasonable. In Employment Tribunal cases, tribunals frequently find that employers have not adequately explored alternatives before declining.

Disagreements

If an employee and employer disagree about whether an adjustment is reasonable:

1. Escalate internally — HR or a more senior manager should review the decision
2. Occupational health review — an independent OH assessment can provide a neutral view
3. ACAS early conciliation — free, confidential, and often resolves disputes before they reach tribunal
4. Employment Tribunal — claims must be filed within 3 months (minus 1 day) of the failure to adjust
