Ask the employee what would help — don't assume — and keep the disclosure confidential. Autism is a disability under the Equality Act 2010, so you must make reasonable adjustments, with or without a diagnosis. Thank them for telling you, and resist the urge to reach for a checklist of "autism adjustments". Every autistic person is different, so the support that works is the support they tell you they need.
First: respond well, and protect the information
The disclosure itself is the most fragile moment, so handle it with care. Treat what they have told you as confidential personal data about their health: under UK GDPR and the Data Protection Act 2018 you cannot pass it to colleagues, or even to other managers, without the employee's consent. Agree together who needs to know and why. A good opening question is simply, "What would make work easier for you, and what gets in the way at the moment?" That puts the employee in charge of their own support rather than having it done to them.
You do not need to see proof. A worker does not need a formal diagnosis to be protected, and Acas is clear that you should offer support whether or not one exists. You can ask for evidence of how the condition affects their work, but they are not legally required to provide it, and pressing for a diagnosis letter is rarely the right first move.
Second: agree and trial adjustments together
Reasonable adjustments are individual, so work them out with the person rather than for them. Acas advises listening to the worker, trying changes out, and reviewing them regularly — adjustments that help one autistic employee may do nothing for another. Common starting points include:
- Written instructions and meeting notes to back up anything said aloud.
- A quieter workspace, or noise-cancelling headphones.
- Advance notice of changes to plans, rooms or rotas.
- Flexible or fixed hours, and structured one-to-one check-ins.
Write down what you agree and put a review date on it. A short record now is your best evidence later that you took the duty seriously, and it gives you both something to adjust as needs change. For a fuller list, see what reasonable adjustments should we make for an autistic employee.
The legal duty, and where to get help paying for it
Autism can meet the Equality Act definition of disability — a mental impairment with a substantial, long-term effect on everyday activities (section 6) — and the disclosure puts you on notice, so the duty to make reasonable adjustments (section 20) is triggered. You, the employer, cannot ask the employee to pay for the adjustments. The case for getting this right is also commercial: the Government's Buckland Review of Autism Employment (published February 2024) found autistic people have one of the lowest employment rates of any disability group, so retaining the staff you have matters.
Where support costs more than you can reasonably provide, the DWP's Access to Work grant can fund practical help beyond your own adjustments, such as a job coach or specialist equipment. Waiting times are long, so the employee should apply early. Whether autism counts as a disability in a given case turns on its effect on that person, not the label; see is autism classed as a disability under UK law, and on the confidentiality point, do we have to keep an employee's neurodivergence confidential.
