Following comments by Professor Dame Uta Frith about the broadening definition of autism and the growing reliance on self-reporting, a practical question has moved to the front of the operational accessibility agenda.
Not: “Is this person disabled?”
But: “What do we do when someone asks for a reasonable adjustment based on a self-diagnosed condition?”
For venues, stadiums, theatres, and visitor attractions, this is no longer a theoretical question. It's an operational one that many staff are already facing.
The Real-World Scenario
Imagine you're the duty manager. A member of your team radios through.
“I've got a guest here who says they're self-diagnosed autistic. They don't have an Access Card or any other evidence, but they're becoming overwhelmed and are asking to use the sensory room.”
“This guest says they're experiencing sensory overload. Can we move them into the VIP lounge because it's quieter?”
What should the answer be?
Many organisations worry that saying yes could create inconsistency or encourage abuse of the system. Others fear that saying no risks discriminating against a disabled person. Both concerns are legitimate. Neither provides a clear operational answer on its own.
What the Equality Act Actually Requires
The starting point is the legal framework itself. The Equality Act 2010 doesn't require a formal diagnosis before the duty to make reasonable adjustments arises. It requires a disabled person to demonstrate that they meet the statutory definition of disability: a physical or mental impairment that has a substantial and long-term adverse effect on the ability to carry out normal day-to-day activities.
Self-diagnosis doesn't automatically meet or fail that test. What matters is whether the impairment actually exists and actually has the required effect, not how it came to the individual's attention.
The constructive knowledge principle from the 2026 EHRC Code is relevant here. Where a customer's circumstances indicate that assistance may be required, staff can't simply refuse to engage until formal documentation is produced. They need to assess the situation in front of them.
There's a practical framework for handling these situations that protects both the customer and the organisation — and it doesn't require staff to make disability assessments. It requires them to assess observable behaviour and respond proportionately.
The key is distinguishing between the question “is this person disabled?” which is not a question for frontline staff, and the question “is this person in genuine distress and would using the sensory room help?” which is.
