While the test centre will keep the results for a reasonable amount of time and the test is valid for an indefinite period, it is still advisable to take the test when a person is ready for application of indefinite leave to remain and British naturalization. Another reason for taking the test close to the application of indefinite leave to remain and British naturalization is that the pass notification letter might end up being misplaced or lost and the examinee will be forced to do the whole procedure again causing so much inconvenience and unnecessary expense.

For disclosure of the time limit it would be best to call the Home Office Border and Immigration Agency, contact information is available on their website. Calling the test centre also for more specific information would be best as it will be the one responsible for keeping the data with regards to the person taking the Life in the UK Test.

Being informed with all the necessary information with regards to the technicalities of this test apart from being knowledgeable of what questions and situations would arise on the test itself is necessary to avoid technicalities that would end up disrupting the flow the paperwork in the application of British citizenship or indefinite leave to remain. From what was mentioned in the first question, the best time to do the test is when the applications for either British citizenship or indefinite leave to remain are ready so that it can be sent to the Home Office right away upon receiving pass notification letter.
