Life in the UK Test: the unique reference number you receive

Short answer: When you pass the Life in the UK Test you receive a unique reference number, which you need to complete your citizenship or settlement application. The Home Office uses it to check that you passed. Tests taken before 17 December 2019 produced a letter with a test reference ID instead.

Key facts, read from GOV.UK on 5 October 2026
  • If you pass, you receive a unique reference number, which you need to complete your citizenship or settlement application.
  • The Home Office uses that number to check that you passed.
  • Tests taken before 17 December 2019 produced a letter with a test reference ID instead.
  • GOV.UK describes the booking service as the only official government service for the test.

What you actually receive

GOV.UK says that if you score 75% or more you get a “unique reference number”. It is the thing the application asks for. The page does not describe a separate paper certificate, and we have not found an official statement saying one is issued, so we make no claim about that either way. What matters is that the pass is held on a record the Home Office can look up, and the number is how it finds it.

GOV.UK gives no separate recovery route for a lost unique reference number. For test queries the helpline is 0800 015 4245, Monday to Friday, 8am to 8pm, or support@lituk.psionline.com.

What to do after a pass

  1. Write the reference number down exactly as shown and keep it with your application papers.
  2. Check that the name on your booking matches your application name. The booking name must exactly match the ID used to book.
  3. Enter the number when the application form asks for the test, rather than relying on a printout alone.
  4. If you need to apply for citizenship after settlement, remember GOV.UK says you do not need to retake the test if you have passed it before.

Where the number comes from, and why sellers cannot supply one

A reference number exists because someone sat the test at an approved centre, had their photo taken and scored 75% or more. At the centre you must bring the same original ID you used to book, and your photo is taken on the day. An advert that promises a pass, a certificate or a number without sitting the test is selling something that does not match any record, and the Home Office check is built to catch exactly that. The pattern, and what real cheating looks like, are covered at fake Life in the UK test certificates. Using a false result in an application has its own consequences, set out at false test results.

If something went wrong at the test

Complaints must be made within three months of the test date, to complaints@lituk.psionline.com, and PSI should reply within 10 working days. A refund can be requested within three months if the test centre cancelled. You cannot get one if you brought the wrong ID, were ill, were late, did not bring the right documents or refused to be photographed. Report anyone selling passes through the scams page on GOV.UK; the steps are at report a scam.

Frequently asked questions

Do you get a certificate for the Life in the UK Test?

GOV.UK describes a unique reference number for passes. We found no official statement about a separate paper certificate, so we do not say either way. The reference number is what you use to complete a citizenship or settlement application. Keep the number safe, because there is no separate recovery route described for a lost one.

What is the unique reference number for?

You need it to complete your citizenship or settlement application. The Home Office uses it to check that you have passed. It exists only if you took and passed the test at an approved centre. Write it down exactly as it appears when you pass, and keep it with your application papers.

What if I took the test before December 2019?

Tests taken before 17 December 2019 produced a letter with a test reference ID rather than a unique reference number. GOV.UK says that if the letter is lost, you should send a letter explaining this with your application. The same advice applies to citizenship and settlement applications.

Can I buy a Life in the UK Test pass?

No. A pass is recorded when you sit the test at an approved centre with the ID you booked with and score 75% or more. The Home Office checks the reference number against that record, so a bought document cannot stand in for a real pass.

Who do I contact about a problem with my test result or booking?

The Life in the UK Test Helpline is 0800 015 4245, Monday to Friday, 8am to 8pm, or support@lituk.psionline.com. Complaints go to complaints@lituk.psionline.com within three months of the test date, with a reply promised within 10 working days. The helpline deals with booking and test queries, and refunds when a centre cancels have their own three-month limit.
