What is the unique reference number?
It is the number you are given when you pass. The Home Office uses it to check your result, so you need it when you apply for citizenship or settlement. Keep it somewhere you will find it again.
The pass itself is one line in a much longer process. This guide covers the unique reference number you are given, how long a pass lasts, and what the next steps actually are.

Start a free practice testYou passed. That is one requirement met, out of several, and the next steps are worth getting in the right order.
When you pass, you are given a unique reference number. This is the whole proof. There is no framed certificate and nothing arrives in the post to replace it.
The Home Office uses that number to confirm your result when you apply. GOV.UK says plainly that you need it to complete your citizenship or settlement application.
No expiry date is published for it. GOV.UK lists people who have already passed the test among those who do not need to take it again.
In practice that means one pass normally covers you for both settlement and, later, citizenship. You do not sit it twice. Confirm your own case on GOV.UK before you apply, because the rules around exemptions do change.
This catches people out. Passing the Life in the UK test does not prove your English.
They are two different requirements, and most applicants have to meet both. English is usually shown at B1 level or above, through an approved test or a degree taught in English. Some people do not have to prove it at all. GOV.UK explains how to prove your knowledge of English, including who is exempt.
What comes next depends on which door you are walking through.
Both carry a Home Office fee that is far larger than the £50 you paid for the test. Those fees change, so read the current figure on GOV.UK rather than anywhere else — what the test costs puts the £50 in context.
A successful citizenship application ends with an invitation to a ceremony, usually arranged by your local council.
There you make an oath of allegiance to the King, or an affirmation if you would rather not swear by God, and then a pledge to the UK. You are given your certificate of British citizenship at the end.
You are expected to attend within three months of the invitation, so book it as soon as it arrives. GOV.UK explains how citizenship ceremonies work.
If any of that sounds familiar, it should: the ceremony is on the test. Chapter 1 of the handbook covers it, and so does the topic page on the citizenship ceremony.
The last useful thing you can do with a pass is hand the route to whoever asks you next. Most people know somebody a year behind them.
The questions people ask us most about this, answered in a sentence or two.
It is the number you are given when you pass. The Home Office uses it to check your result, so you need it when you apply for citizenship or settlement. Keep it somewhere you will find it again.
No expiry date is published. GOV.UK lists people who have passed the test before among those who do not need to take it again, so one pass normally covers both settlement and citizenship.
You get a pass notification with your unique reference number rather than a framed certificate. The certificate people mean is the citizenship certificate, and that comes at your ceremony much later.
Usually yes. They are separate requirements. Most applicants must also show English at B1 level or above, unless they are exempt.
You make an oath or affirmation of allegiance and a pledge, and you are given your certificate of British citizenship. You are invited to book one after a citizenship application is approved.
Knowing how the test works is the easy half. The other half is knowing the answers.
