Frequently asked questions

Is this service part of the NHS?

We’re private healthcare providers working independently from NHS Wales. This means Cardiff residents can access assessment quickly rather than waiting on lengthy NHS lists. 

Will my GP accept your report?

Our reports are written so the GPs and other professionals involved in your care can use them. Assessments use validated diagnostic tools such as ADOS-2 and follow NICE guidance, which helps ensure the findings are widely recognised. 

If a GP or NHS service prefers to apply their own criteria before acting on a private diagnosis, we’re happy to coordinate with them to keep things joined up, including sending your report directly to your GP. 

What support is available after diagnosis?

Your report includes tailored recommendations for your specific needs. We address practical aspects like sensory adjustments, routine support, social communication strategies and wellbeing. 

We also provide information about Cardiff-based autism services, support groups and practitioners who can offer ongoing help. 

Is the process confidential?

Absolutely. Your privacy is protected under GDPR with secure data handling throughout. All assessment information remains confidential. 

Avoid long NHS waiting times and get the support you need sooner. Book your private online autism assessment with Xyla and take the next step with a trusted provider for autism assessments in Cardiff.
