Disclosing ADHD at Work
Should You Tell Your Employer About Your ADHD? Pros, Cons, and How to Do It
There’s no single right answer to whether you should disclose an ADHD diagnosis at work — it depends on your employer, your role, your relationship with your manager, and what you actually need. What’s genuinely useful is understanding the real trade-offs, your actual legal position, and how to have the conversation well if you decide to.
Your legal position in the UK
In the UK, ADHD can be considered a disability under the Equality Act 2010 if it has a substantial, long-term adverse effect on your ability to carry out normal day-to-day activities — which, for many people with ADHD, it does. If it meets that definition, your employer has a legal duty to make reasonable adjustments once they’re aware of it, and you’re protected from discrimination because of it. Importantly, that protection only applies once your employer actually knows, which is one of the central trade-offs in deciding whether, and when, to disclose.
The case for disclosing
Disclosing opens the door to reasonable adjustments that can make a real, practical difference: things like written instructions alongside verbal ones, flexibility on start times or sensory environment, noise-cancelling headphones, extended deadlines where genuinely needed, or quieter working arrangements. It also means a manager who understands why you’re asking for something, rather than guessing, which tends to produce better outcomes than struggling in silence and hoping nobody notices.
The case for being cautious
The honest counterpoint is that disclosure doesn’t guarantee understanding, and stigma around ADHD — being seen as less capable, less reliable, or “difficult” — is still real in many workplaces, even where it shouldn’t be and even where it’s unlawful. Some people choose to disclose only to HR formally, while keeping it private from colleagues or even their direct manager, to access adjustments without broader workplace exposure. Others wait until they’ve been in a role long enough to have a track record that disclosure can’t undermine. There’s no universally correct timing — only what fits your specific situation.
How to do it well, if you decide to
If you do disclose, it tends to go better with some preparation: be specific about what you need rather than only naming the diagnosis (for example, “I work best with written follow-ups after verbal briefings” is more actionable than “I have ADHD”); put the request in writing, even if you first raise it in conversation, so there’s a clear record; know that you can ask for a formal Access to Work assessment, which can fund equipment, coaching or workplace adjustments; and bring documentation (a diagnostic letter, or even a clear screening result alongside a plan to pursue diagnosis) if your employer asks for evidence, since reasonable adjustment duties are generally easier to activate with some form of supporting information.
Whatever you decide, you don’t need a formal diagnosis to start building the skills and strategies that make work easier day to day. Our ADHD Coaching sessions can help you work out what support actually helps, disclosed or not.
