Does the Life in the UK test pass expire?
No, a Life in the UK test pass does not expire. Once you pass, the result is valid for life and there is no expiry date to worry about. That means you can use the same pass first for your settlement (indefinite leave to remain, or ILR) application and later for your citizenship (naturalisation) application. You do not have to sit the test again if you have already passed it.
This catches a lot of people out, because there is a widespread myth that the pass "lasts two years". It does not. GOV.UK does not set any validity period on the Life in the UK test, and the Home Office caseworker guidance confirms that an applicant is only required to pass the test "if they have not already done so". Once it is on your record, it stays there.
- A Life in the UK test pass is valid for life. There is no expiry date.
- The same pass counts for both ILR and citizenship. You do not retake it.
- When you pass, you get a Unique Reference Number (URN), not a certificate that expires.
- The Home Office uses your URN to verify your pass on your immigration application.
- The "two-year validity" idea is a common myth. It does not apply to this test.
What you actually get when you pass
When you pass the Life in the UK test, you do not receive a printed certificate that sits in a drawer and expires. Instead, GOV.UK confirms you get a Unique Reference Number (URN): "You'll get a 'unique reference number'. You'll need this number to complete your citizenship or settlement application."

Since 17 December 2019, the test provider (PSI) no longer issues paper pass notification letters. Instead, your result, with your URN, is recorded in your online PSI Life in the UK account, and you also receive an email confirming your result. If you took the test before that date, you will instead have a letter showing a "test reference ID", which does the same job.
The key point is that your pass is recorded against you. The Home Office uses your URN to check that you have passed. You do not normally need to post any physical document.
Why the pass never expires
The Life in the UK test measures a knowledge requirement that, once met, is treated as met. The Home Office's knowledge of language and life caseworker guidance makes this clear: a person who has already passed the test does not have to pass it again for a later application. So if you passed the test to get your ILR, that same pass satisfies the requirement when you apply for British citizenship a year or more later.
This is different from the English language requirement, which can be met in several ways (such as a B1-level qualification or a degree taught in English). Some of those routes have their own rules, but the Life in the UK test itself has no shelf life.
If you are unsure whether you need the test before or after your immigration application, read our guide on whether you take the Life in the UK test before or after applying for citizenship or ILR.
Keep your URN and pass confirmation safe. You might pass the test for ILR and not apply for citizenship until years later, and you will still need that Unique Reference Number for the second application. Save the confirmation email and note the number somewhere secure.
What to do if you have lost your URN
Because you may need the number long after you sat the test, losing it is a genuine worry, but it is recoverable. Your URN is stored in your PSI Life in the UK online account, so start by signing back in there to view your result. If you cannot access the account or took the test before December 2019, contact the official Life in the UK Test helpline to recover your details. Your pass still exists on record even if you have mislaid the number.
Have your personal details ready. The name, date of birth and ID you used on test day, so your record can be matched quickly.
The bottom line
A Life in the UK test pass is a once-in-a-lifetime achievement in the most literal sense: pass it once and you never need to pass it again. There is no expiry date, no renewal, and no two-year clock. The one thing you must not lose is your Unique Reference Number, because that is how the Home Office links your pass to your application, for both settlement and citizenship.
If you have not sat the test yet, the best way to make sure your first attempt is your last is to prepare properly. Our Life in the UK test 2026 guide walks you through the format, the pass mark and how to revise so you pass first time.
