Is ADHD a disability under the Equality Act?
Under the Equality Act 2010, a person has a disability if they have a physical or mental impairment that has a substantial and long-term adverse effect on their ability to carry out normal day-to-day activities. ADHD can qualify as a disability under this definition, but whether it does in any individual case depends on the impact of the condition on that person specifically.
"Substantial" means more than minor or trivial. "Long-term" means the condition has lasted or is likely to last at least 12 months. ADHD, as a lifelong neurodevelopmental condition, typically satisfies the long-term requirement without difficulty. Whether it satisfies the substantial impairment requirement depends on its actual impact on your day-to-day activities, including at work.
Importantly, the Act requires the assessment of impairment without taking into account the effect of any measures taken to manage or correct it. This means that if you have developed extensive coping strategies that reduce the visible impact of your ADHD, the underlying impairment before those strategies is what is legally relevant, not the degree to which you appear to manage.
The duty to make reasonable adjustments
Where a provision, criterion, or practice of an employer puts a disabled person at a substantial disadvantage compared to a non-disabled person, the employer is under a duty to take reasonable steps to avoid that disadvantage. This duty applies to all employers regardless of size, including sole traders and small businesses, though what is reasonable takes into account the employer's resources and the practicality of the adjustment.
"Reasonable" is assessed on a case-by-case basis. Factors considered include the effectiveness of the adjustment, the cost and practicality of implementing it, the disruption caused, the financial resources of the employer, and whether assistance is available from external sources such as Access to Work. An adjustment that is straightforward and low-cost is more likely to be considered reasonable than one that is expensive or operationally disruptive.
The duty is to make adjustments that are reasonable, not to provide whatever the employee requests. However, the employer must actively consider what adjustments could be made, and a failure to engage with the question at all is unlikely to be defensible. In practice, many adjustments are simple, cost nothing, and benefit the working environment more broadly.
What reasonable adjustments look like for ADHD
The adjustments that are most useful for employees with ADHD vary considerably between individuals and roles, but some patterns are common. Flexible working arrangements, including adjusted start and finish times or the ability to work from home on days requiring sustained concentration, address the difficulty many people with ADHD have with rigid schedules and commuting transitions. Written rather than verbal instructions and meeting summaries address working memory difficulties. Access to a quieter workspace or noise-cancelling headphones addresses distractibility.
More substantive adjustments might include breaking large projects into clearly defined stages with interim deadlines rather than a single distant deadline, adjusting performance review criteria to reflect output quality rather than process compliance, or providing regular check-ins with a manager to support task prioritisation and accountability.
Access to Work, a government scheme administered by the Department for Work and Pensions, can fund adjustments that go beyond what is reasonable for the employer to provide alone. This includes specialist coaching, assistive software, and support workers. Access to Work applications require evidence of a disability and can be supported by a diagnostic report.
"A reasonable adjustment is not a concession. It is a legal right, and it exists because the same working conditions that are neutral for most people can constitute a significant disadvantage for someone with ADHD."
Do you have to disclose your diagnosis?
You are not legally required to disclose an ADHD diagnosis to your employer. However, an employer cannot be expected to make adjustments for a disability they are not aware of. If you want adjustments to be made, some level of disclosure is practically necessary, though you can control the level of detail you share.
You may choose to disclose to HR rather than to a line manager, to share only what is relevant to the adjustments you are seeking, or to frame the conversation around functional needs rather than the diagnosis itself. There is no single right approach, and it is worth thinking through what you want from the conversation before having it.
Once disclosed, a disability must not be used as a basis for discriminatory treatment. Direct discrimination (treating someone worse because of their disability) and indirect discrimination (applying a policy that disproportionately disadvantages disabled people without justification) are both unlawful under the Equality Act.
How to request adjustments
The practical starting point is usually a conversation with HR or a line manager, framing the request around specific functional needs and the adjustments that would address them. Providing your diagnostic report, or the GP letter it includes, gives the employer the clinical evidence needed to understand the basis of the request.
It is worth making requests in writing and keeping records of conversations. If an employer declines to make an adjustment, they should explain why it is not considered reasonable. If you believe the refusal is unlawful, the next step is your employer's internal grievance process, followed if necessary by a claim to an employment tribunal.
Occupational health referrals are a common part of this process in larger organisations. An occupational health assessment, supported by your diagnostic report, can provide an independent clinical opinion on what adjustments are appropriate, which can be useful in conversations where the employer is uncertain.

What employers cannot do
Employers cannot ask about disability or health conditions before making a job offer, with limited exceptions. They cannot withdraw a job offer, dismiss an employee, or treat an employee unfavourably because of a disability. They cannot apply policies or practices that disproportionately disadvantage disabled employees without objective justification.
Harassment related to disability, including comments, behaviour, or a working environment that violates the dignity of a disabled employee or creates an intimidating, hostile, degrading, humiliating, or offensive environment, is also unlawful. If you experience any of these, the Equality and Human Rights Commission provides guidance on next steps, and an employment solicitor can advise on the specific circumstances.
How your diagnostic report supports this process
A formal ADHD diagnosis from a GMC-registered consultant psychiatrist provides the clinical evidence base for a workplace adjustment request. Your Distinct report documents the diagnosis, the impact on your functioning, and clinical recommendations, which are the elements an employer or occupational health professional needs to consider what adjustments are appropriate.
A supporting letter addressed specifically to your employer, setting out the diagnosis and relevant functional impact in terms suited to a workplace audience, is available on request. This can be more appropriate than sharing the full clinical report in some circumstances, particularly where you want to limit the detail shared.
