The date you apply is important
You get paid from the date you applied. If you apply after you turn 65 you won't be back-paid.
You have 20 working days after you first apply to give the Veteran's Pension Centre any other documents needed to complete your application. Otherwise, you may need to apply again. Contact them if you need more time.
