ADHD affects an estimated 3–4% of UK adults, yet the NHS ADHD Taskforce found in 2025 that the condition remains “under-recognised, under-diagnosed, and under-treated.” For employers, the cost of that neglect is staggering – an estimated £17 billion a year in lost productivity, higher turnover, and increased sickness absence.
Most organisations that do act stop at reasonable adjustments. That is a start, but it is not enough. To close the performance gap, HR and wellbeing leads need to understand what ADHD coaching does – and why it belongs in every neuroinclusion strategy.
The Scale of the Problem Employers Can’t See
Nearly 550,000 people were on waiting lists for an ADHD assessment in England as of March 2025, with adult waits averaging over two years. Many of those people are in your workforce right now, struggling without a diagnosis.
Even among employees who do have a diagnosis, the City & Guilds Neurodiversity Index found that 76% have not disclosed their condition to their employer. CIPD’s Neuroinclusion at Work report paints a similar picture: a third of neurodivergent employees say their work experience negatively affects their mental wellbeing, and one in five has experienced harassment or discrimination related to neurodivergence. It is no surprise people stay quiet.
The consequences show up in performance data whether or not anyone discloses. Research from the World Health Organisation estimates that employees with untreated ADHD lose around 22 working days of productivity per year. They are 60% more likely to be dismissed and three times more likely to leave a role impulsively. In a 2024 Acas poll of 1,650 managers, 59% admitted they lacked the knowledge to support neurodivergent team members effectively. The gap between awareness and action remains wide.
Why Adjustments Alone Fall Short
Under the Equality Act 2010, employers have a legal duty to make reasonable adjustments for employees whose ADHD has a substantial, long-term effect on daily activities – and no formal diagnosis is required to trigger that duty. Common adjustments include noise-cancelling headphones, flexible start times, task-management apps, quiet workspaces, and written follow-ups after meetings.
These interventions matter. But they address the environment, not the underlying executive function challenges that define ADHD in a work context. ADHD is associated with a developmental delay of up to 30% in executive functioning – the cognitive processes that govern planning, prioritisation, task initiation, time management, and emotional self-regulation. A standing desk does not teach someone how to break an overwhelming project into manageable steps. Flexible hours do not build the skill of estimating how long a task actually takes.
As Leanne Maskell of ADHD Works has put it, a common employer mistake is assuming that reducing workload will help. “Nine times out of ten, we’re brilliant at the big stuff – our brains thrive on adrenaline. The things we tend to struggle more with are the small tasks.” Adjustments are a necessary foundation, but without a skill-building layer on top, they leave the hardest part of ADHD unaddressed.
What Coaching Does That Adjustments Cannot
ADHD coaching is distinct from therapy. Where cognitive behavioural therapy addresses thought patterns, emotional processing, and co-occurring conditions like anxiety, coaching is practical, future-focused, and goal-oriented. It targets the execution gap. That is to say, the space between knowing what to do and consistently doing it.
In my work at Rikta Coaching, where we deliver executive function coaching remotely to adults with ADHD across the UK, the pattern is consistent. Clients rarely lack intelligence or motivation. What they lack are reliable systems for translating intention into action: how to start a task they find unstimulating, how to protect a morning for deep work when their inbox pulls them sideways, and how to plan a week realistically rather than optimistically.
A coaching programme typically runs over 12 to 24 sessions, building personalised strategies for time management, prioritisation, task initiation, and self-regulation. Between sessions, structured homework embeds these strategies into daily routines. The approach is collaborative – the coach does not prescribe solutions but helps the client design systems that work with their brain rather than against it.
The evidence supports this. A descriptive review published in the Journal of Postsecondary Education and Disability examined 19 studies of ADHD coaching outcomes and found that every study showed improvements in ADHD symptoms and executive functioning, with the majority reporting statistically significant results.
A 2024 meta-analysis in SAGE Journals comparing pharmacological and psychosocial interventions for work-relevant ADHD outcomes found that coaching and psychological interventions may be more effective than medication alone for targeting workplace challenges, because the skills learned are transferable across contexts. As the clinical adage goes: pills don’t teach skills.
The Business Case HR Cannot Afford to Ignore
The economics are compelling. The University of Nottingham calculated in 2019 that each adult with ADHD is associated with over £18,000 in additional costs per year compared to a sibling without the condition – spanning lost income, lower tax contributions, and higher public service use. A typical ADHD coaching programme costs between £2,000 and £5,000. The return is not speculative; the International Coaching Federation reports an average ROI of seven times the cost of a coaching engagement across its global research.
Crucially, UK employers can access coaching at minimal or zero net cost through the government’s Access to Work scheme, which funds ADHD coaching as a workplace adjustment – grants can cover up to £69,000 per employee per year. Yet fewer than 1% of eligible individuals currently use the scheme. HR teams that proactively signpost Access to Work and include coaching in their adjustment toolkit are leaving money on the table if they do not.
Three Practical Steps for Wellbeing Leads
First, think in three layers. The most effective ADHD support is a three-legged model: medical treatment (medication managed by a clinician), environmental adjustments (workplace accommodations), and skill-building (coaching). Most employers only offer the second leg. Adding coaching closes the loop.
Second, know what to look for in a coach. Seek practitioners with recognised credentials – an ICF (International Coaching Federation) or EMCC accreditation, ideally with ADHD-specific training through bodies like the Professional Association of ADHD Coaches. Ask about their approach to executive function, their experience with working professionals, and how they distinguish coaching from therapy. An organisation with clinical roots or links to psychiatric expertise, as we have at Rikta Coaching through our sister clinic, adds a layer of rigour – but the coaching itself should remain firmly practical and non-clinical.
Third, don’t wait for disclosure. With three-quarters of neurodivergent employees choosing not to disclose, reactive policies will miss most of the people who need support. Frame coaching as a performance and development tool available to anyone, not as a remedial intervention triggered by a diagnosis. Normalise it within your wellbeing programme and you lower the barrier for the employees who stand to benefit most.
ADHD coaching is not a luxury add-on to a neuroinclusion strategy. It is the layer that makes the rest of it work.
