Sheffield health group doubles in size as demand for ADHD and autism support surges

A Sheffield healthcare provider specialising in neurodiversity, mental health, addiction and has almost doubled in size over the last year as demand for ADHD and autism support continues to rise across the UK.

Montrose Health Group, headquartered in Sheffield and regulated by the Care Quality Commission (CQC), has reported significant growth over the past 12 months following the launch of its dedicated ADHD and Autism service and a major expansion of its clinical and operational team.

The business has doubled in size and opened an additional Sheffield clinic and operational hub, and recruited 15 new members of staff including a finance manager, clinic operations team, medical director, clinical director and a growing team of specialist assessors and administrators.

Montrose has also already supported more than 200 clients through its ADHD and autism service in its first nine months, and now has the capacity to treat 600 patients per month.

That growth is expected to continue.

The business plans to expand significantly over the next 18 months and has ambitions to grow to around 100 employees nationally as part of wider plans to establish regional assessment centres and increase access to neurodiversity support across the country.

The expansion comes at a time of growing national demand.

According to NHS figures referenced by Montrose, an estimated 2.5 million people in the UK are thought to have ADHD, while more than 562,000 NHS referrals for ADHD diagnosis remained open at the end of 2025. Autism referrals nationally have increased five-fold since 2009.

In April 2026, Montrose secured a Right to Choose contract with South Yorkshire Integrated Care Board to deliver ADHD and autism assessments and treatment for children aged six and over, alongside adult services.

For founder and CEO Jonathan Edgeley, the growth reflects a healthcare system under pressure and a conversation that still has further to go.

He said: “We’ve seen huge growth because demand is increasing at a rate that support simply isn’t keeping pace with.

“There is more awareness around ADHD and neurodiversity than ever before, which is positive, but awareness alone doesn’t equal access.

“People still face long waiting lists, inconsistent pathways and often mixed messages about where to turn.

“There’s also a real need to improve understanding and support in workplaces and help employers make the right reasonable adjustments for neurodiverse individuals.”

Montrose originally launched after identifying a direct correlation between addiction and ADHD within clients accessing addiction and mental health support.

Jonathan explains: “We were increasingly seeing undiagnosed and untreated ADHD presentations among people entering our residential services.

“That led us to begin carrying out assessments internally and ultimately ask a bigger question. If we’re seeing this here, how many more people are waiting for answers?

“That became the catalyst for creating what we believe is a gold standard assessment and treatment service.”

Unlike providers focused solely on diagnosis, Montrose has built its service around a broader treatment pathway, offering assessment, medication support, coaching and ongoing care.

The business operates across private ADHD and autism assessment services, residential addiction and mental health treatment and wider outpatient mental health support.

Its residential offer in the Peak District includes what Montrose describes as the UK’s first and only CQC-registered medical retreat and serves both UK and international clients with specialist programmes for ADHD and autism burnout.

Edgeley, who was diagnosed with ADHD later in life at the age of 48 and has spoken publicly about recovery and mental health following more than 12 years of sobriety, believes the next challenge lies beyond diagnosis.

He said: “There’s still a huge amount of misunderstanding around neurodiversity.

“One of the biggest risks is people assuming diagnosis is the finish line when actually it should be the beginning of support.

“While more individuals are now being assessed, there also needs to be wider understanding from employers, families and communities to continually support positive wellbeing.”

Looking ahead, Montrose plans to expand nationally through regional assessment hubs and by working with NHS partners while continuing to develop support for employers and professional sectors.

New initiatives already underway include the launch of Vulnerable Client Guide – Neurodiversity in Focus, being developed with strategic partners including Payne Hicks Beach and Hall Brown across the legal, financial and wealth sectors.

The business ultimately wants to become one of the UK’s leading providers of ADHD and autism assessment and treatment while continuing to grow its specialist mental health and residential services.

Jonathan added: “This is about creating something that genuinely changes outcomes in the lives of our patients, their families and the community.

“We want to help raise standards, reduce waiting times and make sure people receive support that is compassionate, evidence based and built around people as individuals.

“The demand is there. Our job now is making sure the support exists too.”
