Reasonable adjustments for ADHD at work: a practical guide for HR

Written by Imogen Clark | November 3, 2026

Reasonable adjustments for ADHD are changes to how, when or where someone works that remove a barrier their ADHD creates. UK employers have a legal duty to make them where the Equality Act 2010 applies, and the employee does not need a formal diagnosis first. Most cost little: a quieter desk, written instructions, a regular check-in.

What the law asks of UK employers

ADHD (attention deficit hyperactivity disorder) can count as a disability under the Equality Act 2010 when it has a substantial, long-term effect on day-to-day activities. Acas guidance says employers should offer support, including reasonable adjustments, whether or not someone has a diagnosis. The barrier triggers the duty, and it covers recruitment as well as employment.

That matters because many adults wait a long time for an NHS assessment. Waiting for paperwork before acting is a legal risk. In Toghill v Lidl, a tribunal found the employer failed to make reasonable adjustments for an employee with ADHD because it didn't seek advice on running his disciplinary hearing.

ADHD reasonable adjustments at work, by barrier

ADHD affects people differently, so start with what gets in the way. These are common starting points.

Barrier

Adjustments to try

Focus and distraction

A quiet space or noise-cancelling headphones, a standing desk, protected focus time with notifications off

Time management

Short regular check-ins, projects broken into dated steps, shared task tools and reminders

Working memory

Written actions after meetings, agendas sent in advance, recorded briefings

Energy and burnout

Extra breaks, varied tasks, flexible start and finish times

Formal processes

Questions in writing beforehand, extra time, breaks during performance or disciplinary meetings

 

How to agree and review them

  1. Ask what the barrier is and what has helped before. The employee often knows.
  2. Get advice when you need it. Occupational health or a workplace needs assessment can recommend specific changes, and the government's Access to Work scheme can fund support beyond standard adjustments.
  3. Agree adjustments in writing and set a review date. Acas recommends trialling adjustments and checking they still work as roles change.
  4. Adjust formal procedures before a performance or disciplinary process starts.

 

Where adjustments stop

Adjustments change the job. They don't give someone clinical support to understand their ADHD, manage symptoms, cope while waiting for an assessment, or adapt after a diagnosis. Private medical insurance (PMI) usually covers the assessment and little else. An employee assistance programme (EAP) offers short-term counselling and signposting.

Without that support, the cost shows up as absence, presenteeism and people leaving. Peppy gives employees unlimited, confidential access to specialist neurodiversity clinicians through an app, before, during and after diagnosis. It sits alongside your adjustments process, your EAP and your PMI, and supports more than 3 million people at 250+ employers in 20+ countries.

 

FAQs

Does an employee need an ADHD diagnosis to get reasonable adjustments?

No. Acas advises employers to consider adjustments whether or not someone has a diagnosis. What counts is the barrier the person faces at work.

Is ADHD a disability under the Equality Act 2010?

It can be. ADHD meets the legal definition when it has a substantial and long-term effect on someone's normal day-to-day activities. An employment tribunal makes the final decision in a dispute.

What are examples of reasonable adjustments for ADHD?

Common examples include a quiet place to work, noise-cancelling headphones, written instructions, regular check-ins, flexible hours, extra breaks and support during formal meetings.

Who pays for reasonable adjustments?

The employer pays for adjustments that are reasonable for their size and resources. Access to Work can help fund support that goes beyond what the employer is expected to provide.

Can an employer refuse a reasonable adjustment?

Yes, if the adjustment isn't reasonable. Cost, practicality, the size of the organisation and whether it would remove the barrier all count. Employers should record why and offer alternatives.
