It is so important to take the correct ID with you to the test, if you don't they won't let you take the test, you will loose your money, and you will have to book again!
Over the many years that I have been teaching a course for the Life in the UK test, a handful of students have arrived at the test centre with the wrong ID and have been turned away.
They don't make any exceptions - and it's very frustrating and disappointing after all that preparation to be turned away and have to rebook.
If you're not sure about whether you have the correct photographic ID or not, contact the Life in the UK test helpline on : 0800 015 4245
And do be aware that at the test centre your photo will also be taken on the day to confirm your ID - so be prepared for this to happen.
