The Asylum Substantive Interview and Credibility Assessment

What the substantive asylum interview is

After you claim asylum in the UK, the Home Office holds a substantive interview— the main interview where you explain, in detail, why you fear returning to your country and why you need protection.

A central part of the decision is the credibility assessment: whether your account is accepted as consistent, plausible and supported. Decision-makers look at internal consistency, how your account matches country information (CPIN / country guidance), and whether you claimed at the earliest reasonable opportunity.

Why credibility matters so much

Many asylum claims succeed or fail on credibility rather than the law itself. Inconsistencies, vague dates, or accounts that don’t match country evidence can lead to refusal — even where the underlying fear is genuine. Careful preparation is therefore critical.

How to prepare

• Know your own account — dates, places, events, and the timeline of what happened.
• Be consistent with your screening interview and any written statement.
• Explain gaps or delays — there are often good reasons (trauma, fear, lack of advice) that should be put forward.
• Gather supporting evidence — documents, medical or expert reports, and country evidence where relevant.
• Request adjustments if you are vulnerable (for example a female interviewer or interpreter, or breaks).

Related protections

If your situation involves trafficking or modern slavery, a separate process — the National Referral Mechanism (NRM) — may apply alongside your asylum claim. If your claim is refused, you may be able to appeal or make further submissions (a fresh claim).

Frequently asked questions

Arrangements vary; a solicitor can advise on attendance and, importantly, prepare you beforehand and review the interview record.

What if I make a mistake in the interview?

Errors can often be addressed afterwards in writing. Tell your solicitor as soon as possible.

What is a credibility finding?

It’s the decision-maker’s assessment of whether your account is believed. It’s central to most asylum decisions.
