Reasonable Adjustments in the Workplace – UK Employer Guide
What Do Reasonable Adjustments Mean for UK Employers?
Reasonable adjustments require UK employers to take practical steps to remove workplace barriers that place a disabled employee or job applicant at a substantial disadvantage compared to others.
Under the Equality Act 2010, the duty applies where an employer knows, or could reasonably be expected to know, that an individual has a disability and is experiencing disadvantage because of:
A workplace provision, criterion or practice
A physical feature of the premises
A lack of auxiliary aids or support
The obligation is proactive. Employers are not expected to guess, but they are expected to respond appropriately once a potential disadvantage becomes apparent.
In practical terms, this means reviewing how work is structured, how communication takes place, how performance expectations are set, and whether environmental factors may be creating avoidable barriers.
Reasonable adjustments are not about lowering standards. They are about removing obstacles so that capability can be fairly assessed and performance can be measured on equal terms.
For UK employers, the key considerations are:
Is the individual at a substantial disadvantage?
Is the proposed adjustment reasonable in the circumstances?
Is the adjustment proportionate in cost and operational impact?
Has the decision-making process been documented?
When approached in a structured way, reasonable adjustments reduce legal risk, improve employee engagement, and strengthen inclusive workplace culture.

When Is an Employer Legally Required to Act?
An employer’s duty to make reasonable adjustments arises when three conditions are met:
The individual meets the legal definition of disability under the Equality Act 2010.
The employer knows, or could reasonably be expected to know, about the disability.
The individual is placed at a substantial disadvantage compared to non-disabled colleagues.
A disability, in legal terms, is a physical or mental impairment that has a substantial and long-term adverse effect on a person’s ability to carry out normal day-to-day activities. “Long-term” generally means lasting, or expected to last, 12 months or more.
The duty is not triggered only by a formal diagnosis. If an employee discloses a condition, raises concerns about workplace barriers, or shows consistent difficulty linked to a health condition, employers are expected to consider whether reasonable adjustments may be appropriate.
Crucially, once knowledge exists, inaction can carry legal risk. Failing to explore adjustments may expose an organisation to claims of disability discrimination.
However, the law does not require employers to implement every requested change. Adjustments must be reasonable. In determining reasonableness, tribunals may consider:
The effectiveness of the adjustment in removing disadvantage
The practicality of implementation
The cost relative to the organisation’s size and resources
The availability of external support or funding
For SMEs, this often means proportionate changes that are manageable in scope but meaningful in impact.
Early engagement, open discussion and documented decision-making are central to meeting the legal duty confidently and consistently
Many capable individuals face unnecessary challenges at work, not because of ability, but because the environment, processes or communication styles do not align with how they think and process information.
A Workplace Needs Assessment identifies those barriers and provides clear, practical recommendations that are proportionate, reasonable and legally sound.
Following the assessment, you receive a detailed written report outlining suggested workplace adjustments, implementation guidance and next steps for both the employee and the organisation.

Examples of Reasonable Adjustments for Neurodivergent Employees
ADHD
Employees with ADHD may experience challenges with sustained attention, organisation, time management or task prioritisation. Adjustments might include:
Breaking large tasks into smaller, structured milestones
Providing written follow-up after verbal instructions
Agreeing realistic deadlines with interim review points
Allowing use of noise-cancelling headphones
Flexible scheduling where operationally possible
The focus is on reducing cognitive overload and improving clarity.
Autism
Autistic employees may experience differences in social communication, sensory processing or routine changes. Adjustments may include:
Providing clear, unambiguous written instructions
Offering predictable schedules where feasible
Minimising unnecessary last-minute changes
Adjusting lighting or workspace location to reduce sensory impact
Allowing alternative communication methods where appropriate
Small environmental or communication changes can significantly reduce stress and improve performance.
Dyslexia
Dyslexic employees may experience challenges with reading, spelling, processing written information or working memory. Adjustments could include:
Providing instructions in bullet-point format
Allowing additional time for written tasks
Using assistive software tools
Offering verbal clarification alongside written documents
Adjusting assessment formats where appropriate
The aim is to support processing differences without lowering performance expectations.
Dyspraxia
Employees with dyspraxia may experience coordination, organisation or sequencing challenges. Adjustments may include:
Structured task lists
Additional time for practical activities
Clear procedural guidance
Adjusted workspace layouts to reduce physical strain
It is important to emphasise that reasonable adjustments are individualised. Two employees with the same diagnosis may require different support.
Effective adjustments are based on structured discussion and, where necessary, formal workplace assessment to identify specific barriers and proportionate solutions.
How Employers Can Identify Appropriate Adjustments
Identifying appropriate reasonable adjustments is not about guesswork. It requires a structured, evidence-informed approach that focuses on workplace impact rather than assumptions.
Employers should begin with an open and supportive conversation. The purpose is not to interrogate medical details, but to understand:
What aspects of the role are proving difficult
Whether specific workplace practices are creating disadvantage
What changes might remove or reduce that disadvantage
It is important to approach these discussions without preconceived solutions. Adjustments should be based on practical need, not diagnosis alone.
In some cases, informal agreement may be sufficient. For example, clarifying communication methods or adjusting deadlines may be straightforward and easily implemented.
Where challenges are more complex, or where managers feel uncertain about appropriate adjustments, a more structured assessment process may be beneficial. A formal workplace review can:
Identify specific barriers linked to the role
Evaluate environmental and procedural factors
Recommend proportionate and reasonable adjustments
Provide documentation to support decision-making
A structured approach protects both the employee and the employer. It ensures that decisions are evidence-based, consistent, and aligned with legal obligations.
For many SMEs, having a documented process in place reduces uncertainty and demonstrates a proactive commitment to compliance and inclusion.
Common Mistakes Employers Make When Managing Reasonable Adjustments
Even well-intentioned employers can make errors when approaching reasonable adjustments. These mistakes often arise from uncertainty rather than disregard for legal duty.
One common mistake is waiting for a formal diagnosis before taking action. The duty to consider reasonable adjustments can arise based on knowledge of disadvantage, not only medical confirmation. Delaying action may increase legal and employee relations risk.
Another frequent error is treating reasonable adjustments as a one-off event. Adjustments should be reviewed periodically to ensure they remain effective as roles, responsibilities or workplace circumstances change.
Some employers overestimate cost and complexity. In practice, many reasonable adjustments involve changes to communication style, task structure or environmental factors rather than significant financial investment.
Inconsistent documentation is another risk area. Decisions about adjustments — including where adjustments are declined — should be recorded with clear rationale. Transparent decision-making reduces the likelihood of misunderstanding or dispute.
Finally, employers sometimes focus solely on compliance rather than effectiveness. An adjustment that technically meets the duty but does not remove the disadvantage may not resolve the underlying issue.
Avoiding these common pitfalls strengthens both legal compliance and workplace culture.
Practical Steps for SMEs to Implement Reasonable Adjustments
For small and medium-sized enterprises, implementing reasonable adjustments does not require complex infrastructure. It requires clarity, consistency and documentation.
A practical approach can follow five structured steps:
1. Encourage Early Disclosure
Create a workplace culture where employees feel safe raising concerns. Clear communication that the organisation is willing to consider adjustments reduces delay and uncertainty.
2. Hold a Structured Conversation
Focus on workplace impact rather than medical detail. Identify specific tasks, environments or processes that are creating disadvantage.
3. Explore Proportionate Solutions
Consider adjustments that are practical and effective. Evaluate cost, operational impact and feasibility, but avoid dismissing options without discussion.
4. Record Decisions Clearly
Document what was agreed, the reasoning behind decisions, and review timelines. Written records provide clarity and reduce future dispute risk.
5. Review and Refine
Adjustments may need refinement over time. A short review meeting after implementation can confirm whether the change has removed the disadvantage.
For SMEs without dedicated occupational health resources, a consistent internal framework provides reassurance and reduces legal risk. Where internal confidence is limited, a structured Workplace Needs Assessment for Neurodiversity can provide clarity and independent guidance.
Reasonable adjustments should be seen as part of good management practice, not exceptional treatment. When approached systematically, they strengthen productivity, retention and organisational resilience.

Conclusion: Taking a Structured Approach to Reasonable Adjustments
Reasonable adjustments in the workplace are not simply a compliance obligation. They are a practical mechanism for removing avoidable barriers and enabling individuals to contribute effectively.
For UK employers, the key is structured decision-making. Early conversation, proportionate assessment, clear documentation and periodic review form the foundation of a legally sound and operationally effective approach.
Most adjustments are not complex. The difficulty often lies in uncertainty — understanding when the duty arises, what is considered reasonable, and how to determine appropriate solutions.
Where internal confidence or expertise is limited, a structured workplace assessment process can provide clarity. Independent review ensures that adjustments are evidence-based, proportionate and aligned with both the Equality Act 2010 and the realities of the role.
Employers who approach reasonable adjustments systematically reduce legal risk, strengthen workplace culture and support long-term organisational resilience.
