Should I mention mental health in an interview?

When disclosure is necessary. If your CV has a gap that requires explanation: brief, honest, forward-pointing. 'I took 4 months in 2024 to recover from burnout. I worked with a therapist, rebuilt my work systems, and I'm at full capacity.' That's enough — you don't need to elaborate.

When disclosure is unnecessary. If the role doesn't require adjustments and you don't have a CV gap to explain, you don't need to disclose mental health history. UK Equality Act doesn't require it.

When to disclose post-offer. If you need workplace adjustments — flexible hours during therapy, occasional remote days for managing energy, lighting modifications, breaks during meetings — disclose at the start-date conversation, not earlier. UK Equality Act adjustments are mandatory once disclosed.

If asked directly. UK interviewers generally shouldn't ask about mental health, but some do indirectly ('How do you handle stress?'). Honest brief response: 'I've built better systems for high-pressure periods than I had previously.' Doesn't disclose detail; signals self-awareness.

What protections exist. Equality Act 2010 protects candidates from discrimination based on mental health condition (where it qualifies as a disability — significant impact on daily activities, lasting 12+ months). Reasonable adjustments are mandatory once disclosed. Withdrawal of offer based on disclosure is unlawful.
